(Heavy 10) Anyone have a Bull gear for sale? Even one with missing
teeth? Marty (292) |
| Have you ever
checked Harwood's for parts? Harwood's is the tool "junkyard" on
40th St. between the freeway and University. I was there the other
day and saw a SB 10L rusting away outside. I don't think it had a
headstock, but who knows, he may be using it for a door stop. Bob
(293) |
| Quick change gearbox
|
| Does anyone know if the QC gearbox from a 10" will fit on
the 9". The units look identical but I don't have it in my hands to
check the measurements (looking to purchase). Frank (581) |
| My understanding is that
the 10K and 9A use the same gearbox. The 10L might use the same one
but am not sure. The heavy 10 is supposed to be the same as the 11
and 12" machines which are different. JWE (583) |
| Depending on which model of 10" lathe, it might. As pointed
out by Mr. Early, the 9" and the 10K gearboxes were the same. The
gearboxes (single or double tumbler) for the "Heavy Ten" will not
fit the smaller 9" and 10K machines. If you are able to examine the
gearbox, look for a unit code. This number is not the catalogue
number on the gearbox tag but is stamped into the tumbler guide bar
under the gearbox. If you find it and it has an "NK" suffix, It will
fit the 9" lathe. One note on adding a gearbox to a 9" B or C model:
You will have to drill and counter bore a third mounting hole in the
bed for the gearbox. Some may have this hole already but most don't.
Webb (587) |
| Will a 10K tailstock
fit any other models? |
| Have an
extra 10K tailstock I was gonna put on eBay and just wondering if it
fits any other South Bend models. (1419) |
| The answer is no. The bed
of the 10K, or "light ten" as it is sometimes called, is identical
to the bed of the 9 inch model. However, the tailstock of the 10K is
too tall for the nine inch unit. The bed of the "heavy ten" is wider
and so the tailstocks of the light and the heavy 10s do not
interchange. (1422) |
| SB Milling Attachment |
| Will a
milling attachment for a 9" fit a 10"? That hybrid of mine has all
10" specs except the swing is 9". Would you rather have a SB or
Palmgren if you were buying? Tim Q (1500) |
| I would think
that the Heavy Ten milling attachment would work. But check the
plinth of your compound against the plinth of the milling attachment
to be sure. The plinth is the inverted conical part that fits inside
the cross slide. Both the 9 inch and 10K lathes use the same milling
attachment. And I believe this is true of your "hybrid" 9 inch and
the Heavy Ten milling attachment. I haven't used the Palmgren
milling attachment but the South Bend Lathe one is reasonably
sturdy. I've used the South Bend Lathe ones until I got a real mill.
If you plan to do much milling, get a true vertical mill. No milling
attachment will give you the capacity or capabilities of a vertical
mill. But they will let you do some small stuff. Webb (1502) |
| Interch of
small/lg dials on a 10L |
| Anybody
know about interchangeability of small and large dials for a 10L? I
am looking into a purchase of a complete taper attachment setup for
my 10L. The taper attachment under consideration has a small dial on
the cross feed. My lathe has the large dials. Does anybody know if I
can simply swap my large dial onto the crossfeed screw in place of
the small dial? (2855) |
| I don't know about a 10L
but the cross feed shaft on the 9" is longer for the large dial than
the small dial assembly. My understanding this is for clearance when
the saddle is cranked back for large dia work. I also understand
the crossfeed nuts are different with or without the taper
attachment. Ed (2861) |
| 1. It
is not possible to do what you propose because the screws for the
large dials are longer than the screws for the small dials. Also,
the large-dialed screws use roller thrust bearings rather than flat
washers, so they are improved to turn more smoothly. 2. As you
probably know, the screw that goes with the taper attachment is
"telescoping," so that it can be more quickly switched from regular
turning to taper turning. However, it would be possible to use your
current cross feed screw with the taper attachment (2862) |
| I have 2 carriages and
aprons here; trying to do the large-dial conversion and add power
crossfeed at the same time. The large-dial setup has a bushing an
inch and a half or thereabouts longer. The non-threaded part of the
cross slide feedscrew is longer by the same amount as the difference
in bushing length. To effect this swap requires a new leadscrew,
bushing, and dial. I don't know about any difference in nuts for a
taper attachment, although there are 2 different part numbers in the
book for the nut called out for taper equipped or non-taper
equipped. Looks like a Logan 1105 cross-feed screw can be sleeved
for the fat part and shortened a bit on the crank end, at a whole
lot cheaper than OEM--about 1/10 the cost if the reports I have
heard of OEM prices for the screw and nut are accurate--thanks
Scott. When I get my Logan leadscrew I will post the results. (2865) |
| Interch SB 9/10K CF
screw w/ 10L? |
| Does
anyone have experience with the interchangeability of South Bend
9/10K crossfeed screw with the 10L (or Heavy-10) for taper
attachment equipped lathes? I spoke with someone by phone who has a
complete telescoping TA crossfeed screw set (handles, nut, lg dials,
etc) from a 9" South Bend (I am assuming this also same part for
10K, correct me if I am wrong). Based on our phone discussions I
believe there is a strong possibility they will fit my 10L w/ lg
dials. Does anyone know if that is the case or not? Mark (3470) |
| You better check that
attachment out very carefully. My 1966 copy of SB's "How to Run a
Lathe" says "the plain taper attachment is used on all 9" South Bend
Lathes" (non-telescoping) and the telescoping attachment is "used on
all 10" to 16" swing South Bend Lathes" (p. 62). If what that
someone has is truly a telescoping TA, then it may fit, but if it is
truly off of a 9", it likely isn't telescoping. Rick (3473) |
| Will a chuck from a
SB 9" fit a 10K? |
| Both
lathes have a threaded spindle, but I don't know if the thread sizes
are the same. Anyone know? Marv (4958) |
| They should be the same
nose, at least for 9" ~1940's and beyond I believe. The noses are
1-1/2", 8TPI. Paul R. (4959) |
| 10" head stock on a
9" base |
| Does
the 10" head stock with the 1 3/8" thru hole fit the 9" bed. I could
convert my 9" to a 10" with 5C collets for a few hundred bucks.
Kerry (5281) |
| I believe they will fit
on the early 9" like my 9" junior, but the later 9" had a narrower
bed by about 50% I think, measure your bed and get someone in the
group with a 10 to measure theirs that should tell you. scott (5282) |
| "Heavy 9"? |
| I
just swapped a Heavy 10 steady rest I bought by mistake, with a guy
who bought a 9-inch steady by mistake that was too narrow for his
lathe--his fits mine perfectly. My lathe is a 1937 9-inch Workshop
"C". He says the Heavy 10 steady I sold him sits half an inch too
high but fits the ways perfectly. From the bed dimensions, it seems
he has a 9-inch built on a wider, heavy 10 bed. Or does he maybe
have an old 11? Was the pre-fire 11 built on the same bed as a heavy
10? Is there such a thing as a heavy 9? The bed width on his is just
about 3 5/8 center-to-center on the inner ways, versus the 3 1/8 on
my 9. (5476) |
| Your friend probably has
a 9" junior or maybe a 9" model R. these early 9" before the
workshop were the same size beds as a heavy ten. my 9" junior has
the same gears as a heavy ten 16dp and apparently a heavy ten quick
change gear box can be fitted without too much work look in photos I
have a pic of my 9" junior (5477) |
| Taper Attachment
interchange? |
| Will
any 9" SB taper attachment fit directly onto a 10K? If not what do I
need to look at for the correct fit. Robert (7010) |
| Robert, The 9" and 10K
take the same Taper Attachment, Catalog # CL428NK. In the 1958
Catalog this Attachment sold for $93. Jim (7018) |
| Change gear question
|
| Are
change gears for the 9" and 10" lathes interchangeable? Johnny
(7333) |
| Light Ten [10K] yes.
Heavy Ten [10L] I think not, I believe the heavy 10 gears are 16DP
and not 18DP as with the 9 and 10K, but someone check me on this.
(7334) |
| Will micrometer
carriage stop that fits 10K fit 9" |
| I have
a carriage stop stop I have personally bolted to a SB 10K lathe and
fits perfect. can I assume that this carriage stop will also fit a
SB 9"? I have heard that these parts are interchangeable between the
10K (light 10) and the 9". Mark (8636) |
| Mark; The 9" and the 10K
(but not the 10L, also known as a "heavy 10") both use the same
lathe bed. For this reason the bed dimensions are the same and your
carriage stop can be used interchangeably between the two. The
aprons are also the same (provided your 9" is a model A or B) so the
stop flat cast into the apron should be the same in both. Perk
(8638) |
| Headstock fit |
| Will a 9" Under drive headstock fit on a 9" horizontal drive
bed? I don't care about the regular drive method as I am going to
run it with a DC motor controlled from a CNC driver. I have a bed
from a 9" HD and have found a Headstock from an under drive on Ebay.
Jim (9682) |
| It will certainly
fit on the bed but how will you transmit driving power to the
spindle? You would need to do some major butchering on the rear of
the UND casting to run a belt out the back. You are better off
getting the correct headstock for your bed. They come up often
enough on ebay. Peter (9696) |
| Does a Boxford tumbler
reverse fit an SBL9? |
| The UK
manufacturer Boxford copied the SBL9. Does their rather nice spring
loaded tumble reverse mech. fit the South Bend, anyone? Can't much
see the point of a tumble reverse that you need a spanner to
operate, neither did Boxford, I guess. There is a nice mod to use
the 10inch bracket in the files section. Just wondered if there was
an easier route for those of us across the pond. Jon (12735) |
| I used a special
"semi-permanent fitting" square hole spanner with a round, screw in,
handle to lock the tumbler reverse units on my 9" SouthBends. This
spanner was just a square hole sleeve arranged so that when the
handle was screwed in it locked the sleeve onto the square headed
locking bolt. I found that the bolt orientation was right to give a
neat lock/unlock movement without the fixed handle getting in the
way of anything. You might need to make adjustments by adding a
washer or facing off the bolt thrust face. Make the square head
spanner by welding a cover onto a suitable sized bit of steel with a
U shaped slot in it. This lazy character used a nut (6 mm??) to save
having to tap a thread afterwards. I have also made such spanners by
strapping two L shapes or 4 flats around a suitable former and
welding them together. Knurling the business end of the handle is
swanky. Did the same for the bed lock. Clive (12771) |
| From what I can tell the spring tumblers do not fit on a headstock
designed for the other type. The mod in the files section is
required for that to work. My 9" model A originally was designed
with the spring loaded reverse but it was missing when I got it. The
mod shown in the files section is already part of the headstock
casting. The spring tumblers are rare and typically pretty pricey on
ebay so I ended up getting the other type. It fits but I had to face
off the inner side to get the gears to mesh properly. (I then cut
off the handle and fabricated a spring mechanism for it. Works fine.
Of course now that I don't need one, a spring tumbler went at a
REALLY good price on ebay last week. John (12783) |
| 10K and 9" Apron
interchange |
| Are the
aprons from a 10K-model A and a 9" model A interchangeable? The unit
code on the 10K QC gearbox is 600NK1, so I'm sure that part will go
to the 9". Johnny (14007) |
| Don't have either
a 10k or 9 myself but according to parts info I have, Apron on 9"
and Light 10 models A and B are the same carrying part # PT 70 NKI
and 9 and Light 10 Model C are the same carrying Part # PT 70 JNKI.
Heavy 10 in my parts list as well as 13,14 ,14 1/2, and 16 have no
part # in book only notation to "Price On Request ". I would say
from this info that no they do not interchange. Hope someone who
actually owns one will pipe in if they know for sure. Ron (14008) |
| My
friend has a Heavy 10, the apron is noticeably different from my 9A.
(14009) |
| Yes, the parts
that will interchange but are different are the head and tailstock,
they are 1/2" taller on the 10K, otherwise everything else is the
same. Clint (14011) |
| So, if
I understand correctly, a 9" model C, with the addition of a 10K
QCbox, leadscrew, and apron, becomes a 9" model A? Johnny (14012) |
| Yes it would be a Frankenlathe, (g) model A like I said in my last post, if you use
the head and tailstock however, you have built a 10K. Clint (14013) |
| The
compound rest swivel (9 = PT9IN1 ; 10K = PT9IK1) on the compound is
different for the 10K. Tom (14014) |
| The crossfeed
leadscrew needs to have the gear that runs off of the worm gear in
the apron. Glen (14015) |
| Glen is
correct, make sure you get the saddle with the apron. You can use
your compound. Clint (14016) |
| You only need the
model A saddle if you want powered crossfeed. You can do with out it
but it sure is nice to have for large facing jobs. John (14017) |
| Since
the saddle is already gone, I'd better back away from this apron. If
the apron were from a 9A would I still need the saddle to go with
it? I saw a 9A apron on ebay a few minutes ago that ends today, but
here again, no saddle. Johnny (14019) |
| Johnny, It makes no
difference which apron you get, the saddle needs to have the
leadscrew with a gear on the inboard end to work off the worm gear
in the apron. As someone pointed out, you could use the model C
saddle if you are willing to give up powered cross feed. This is a
very nice feature for facing off large diameter parts. It also
really helps for parting off where steady feed rates are necessary.
You might be able to modify the model C crossfeed screw to add the
gear. Does anyone know the DP and tooth count for this gear? Glen
(14020) |
| Glen, I
think you have the parts mixed up. He would need a Model A or B
apron to have power cross feed. It should bolt up to his present C
saddle. He would need the cross feed lead screw. I think there are
some differences in these between lathes with taper attachments or
without. His saddle may need the casting opened up a bit so the
gears can mesh together. I think on some of the C's its not. I have
heard that some of the saddles and aprons from very early 9's are
different and may not bolt up. Still most should. I think using the
present saddle would be best, unless damaged. It should match your
ways. Another saddle may not. Tom (14021) |
| Tom, I meant it doesn't
make any difference whether he uses a Model A 9" apron or a 10K
Model A apron. He still needs the gear on the cross slide leadscrew
to get power from the apron. It would indeed be better to modify the
saddle he has than to get a new one. When I upgraded my "C" to an
"A", my saddle had the geared leadscrew. My lathe was probably
thrown together from a warehouse full of parts in Bristol,
Connecticut. It would be worth the effort to lift off the saddle and
take a peek at the screw to see if the gear is there. Glen (14022) |
| Glen, I
know both you and Clint have done this conversion. I haven't
completed mine yet. I'm building garage space and doing a CNC
upgrade. Busy. Still, I think there are a few missing points and a
few things that seem confusing on how they are presented. Still,
back to what is needed for this conversion. The QC box, the (main)
lead screw for an A lathe (or machining of present lead screw), the
A or B apron for power cross feed, the cross feed screw from an A or
B lathe (it should have the gear, there is a difference for taper or
non-taper attachment lathes) and there is the gear train. I think he
needs the 20T gear for this conversion. I can remember if someone
has these for sale or not. I forget who had them made, but I think
he is sold out of them. Then I think someone else made some. So all
in all he could get the apron on E-Bay and then get a cross feed
screw. Tom(14023) |
| Johnny yes, you can use a
saddle off a 9A on the 10K apron and vice versa. You can also use
either from a model B. Clint (14024) |
| I think
that I have a 20 th gear left over I also have a model A leadscrew,
a Model B leadscrew and a model C leadscrew I also have a saddle and
a screw with the power feed gear, I think! Clint (14025) |
| Lurch found some 20 tooth
gears somewhere and bought all they had. I bought gear cutters and
made 15 or so. I still have a dozen left. I am asking $20.00
including US shipping to cover my cost for the gear cutters. Glen
(14026) |
| Glen
That certainly is a good price on the gears Do you have a cutter to
make the 20th that goes on the A leadscrew? Clint (14036) |
| Clint, If it's 18DP 14.5
degree PA I do, but I thought those were 20DP. Does anybody know? I
guess I could see if a change gear meshes. It'll have to be tonight,
though. Glen (14049) |
| Glen
I'm pretty sure the gear on the leadscrew is smaller in diameter. I
have a gear at home and IIRC it is smaller than the stud screw. I
never compared it to the lead screw but it looks about right. Co you
need a gear Clint? If so what do you have in trade? I'm looking for
parts for a tailstock. Wheel, screw and maybe the quill. Say would a
discarded the crossfeed screw from a model C work? I need 1/2 x10 LH.
with about 2 3/4 of thread. John (14052) |
| The 20 t leadscrew gear
is larger than the 20 t stud gear, but not by much, I was just
comparing them last week Humm! I will have to check on them parts I
have a C model screw. Clint (14064) |
| Glen,
on the 9" if you are talking about the reversing gears that go from
the spindle to the change gears there are both 18 pitch and 20 pitch
gears, both 14-1/2 PA. The spindle gear is a 20 pitch that drives a
compound gear, a 20 to a 18 pitch. All the change gears beyond this
are 18 pitch. I noticed that on my heavy ten and my 13" the same
thing happens. The heavy 10 goes from a 18 to a 16, the 13" goes
from a 16 to a 14. Walt leadscrew? the wrote: few what is the and
conversion. had else cross Tom(14066) |
| I checked last night and
the 20 tooth gear I have is 1.1" OD. I believe this is 20 DP. I
didn't check it against the leadscrew gear. John (14068) |
| No, I
think Clint was talking about the gearbox output gear that goes on
the leadscrew. The stud gear is 18DP, so it's OD should be about (20
+ 2)/18 = 1.222.... inches. If the leadscrew gear is 20DP, it
should be (20 + 2)/20=1.1 inches. Glen (14070) |
| Light 10 vs Heavy 10
differences? |
| I am
waiting on a seller to gather all of the parts to a 1950 Light 10
horizontal drive lathe. He said it had an approximately 0.8" through
hole in the headstock spindle. If he can find all the parts, I am
planning on purchasing it. Through my research, I've learned that
the Heavy 10s had a larger through hole. What are the other
significant differences between the light 10 and heavy 10? (Were
there any horizontal drive heavy 10s?) I really would like the
larger capacity headstock spindle, but can't find any local heavy
10s. Is it possible for me to replace the L10 spindle with an H10
spindle? Anybody know of any Heavy 10s for sale in or near Georgia?
Bill (14627) |
| The 'heavy 10' model
CL187 weighs close to half a ton and has the motor in the base. It
is similar to the 13" and 16" in construction. The large bore has
the letter 'L' in the serial number and has a 1.4" thru hole in the
spindle. The spindles are not interchangeable. The CL187 has a 2
1/4-8 thread and the 10T has a 1 1/2-8 thread. The heavy 10 also has
an optional cam lock or long taper spindle, not sure for the 10T.
The 9 and 10T, which I believe you are referring to are similarly
constructed. They are 1/2 to 2/3 the weight of the heavy 10. The bed
ways are closer together as well on the 10T vs heavy 10. JP (14628) |
| 10K vs 10L Taper
Attachments |
| Is
there any difference between taper
attachments for 10K's and 10L's that would make them not be interchangeable? I have a 10L and the attachment I'm looking at has
the telescoping feed screw. Does the taper attachment for 10K's use
such a replacement feed screw? (15038) |
| The 10K taper attachment
is the same as the BB 9. It doesn't use a telescopic cross feed
screw. The cross feed nut has to be disengaged (remove the screw).

| Will
a 10" Atlas thread dial run on my 9 C sb workshop? Rick (15174) |
| If a 10" Atlas has

or may not fit without modification. John (15176) |
| 10" back gear
assembly |
| Anyone
know if the back gear assembly from a 10" will work on the 9"? W.

| SB 14-1/2 vs SB 16
interchange? |
| Anyone
know about 14-1/2 and 16" SouthBends? The gear box on this lathe had
both sizes on it but the lathe measured 14-1/2. Curious which parts
are interchangeable? Jeff (17650) |
| You need to get the South
Bend Parts manual. You can look at the parts numbers and see which
are the same on both lathes. The 14 1/2 is fairly rare, as they were
only built from 39 to 66 and were less popular than the 13 or 16.
They are much heavier than the 13, and have a number of common parts
with the 16, but have some parts in common with the 13, and some
that are unique to the 14 1/2. Leblond does not support any of the
unique parts, (they don't support the 14 1/2) so you have to get
them on the used market. About 4000 were built from 47 on, and
possibly another couple of thousand before that, so there aren't
that many. My father has one in mint condition from 1963, with
almost all the accessories made for it, and he loves it. When it
sits side by side with a 13 inch, it really makes the 13 inch look
small and light weight. (17658) |
| SB/Logan Follow Rest
|
| File
this under obscure facts A Logan 10" follow rest fits a SB heavy 10
perfectly (19379) |
Which would also mean a
SB H10 follow rest will fit a Logan. If the Logan users find out,
they be after the SB stuff too! Jeff
(19421) |
| Add to
this that a South bend 9" workshop lathe follower rest fits nicely
on a Logan 9B lathe. I have both machines and only a single follower
rest. Also the carriage stops are usable on a Logan. The gearbox on
the Logan keeps you from using the stop up real close to the
headstock, so I do that kind of thing on my B model workshop lathe.
Things that mount on the spindle are usually interchangeable unless
they are fitted exactly to the Logan. The extra.009 on the South
bend will stop it from seating. Most of the things that you get from
Logan are not fitted that tight so they work. It looks to me like
they use a 1.515 reamer (it avoids stuck chucks) RC (19461) |
| Logan 10 steadies
and followers vs SB Heavy 10 |
| A
previous post by Dr. Harms mention that the Logan 10" follower rest
fit the South Bend heavy ten lathe. Is it true for steady rests as
well? I know that Scott Logan is a contributing member of this
group, so I ask if he can verify that. I purchased what I and the
seller believed were South Bend 10" steady and follower rests but
they might be made for Logan's. I will post pictures in a folder
called Logan vs. South bend 10 rests. (19861) |
| I can't be positive, but
it sure looks like those are Logan Steady and Follow Rests. We have
found that the Logan 10/11 Follow will fit without modification on a
SB 10-L (Heavy 10), but I don't know about the Steady Rest. It will
likely need at least a bit of modification, since the heights are
not the same, AFAIK. On the Logan, the heights are 5-1/4" (10") or
5-9/16" (11"). If anyone needs one and wants to order, I will allow
you to return it if it does not fit, no restocking charge. I would
only ask you let me know what it would take to make it fit
correctly, if possible. Scott Logan(19862) |
| Anyone use Boxford
parts on SB lathe? |
| I
currently have 2 south bend lathes a 10K and a 10L I have someone
selling a Boxford lathe 9" that from what I have read and what it
looks like would have some parts interchange with the south bend
(10k or 9") The Boxford looks to be a better made lathe in some
ways. the cross slide is a T slot table with 4 slots so you can
change the location of your compound or use as a boring table. The
quick change box looks to be good quality also. This has has a
variable speed with cone pulleys in the cabinet (very nice) The head
and tail stock look to have a bit more metal to them but the bed
still looks the same as a south bend. It also has a built in coolant
pump in the cabinet. The lathe uses the same 1-1/2 x 8 TPI spindle.
I have read all the information on the lathes.uk site any more info
would be great. (21758) |
| I have used a couple of
Boxford parts on my 1940 9" C, but they were probably not indicative
of full interchangeability. I changed the small dials for direct
reading type from a Boxford, and use a Boxford faceplate. The
slotted crosslide table IS to the best of my knowledge directly
interchangeable, and Tony Griffiths sells these as new parts. Len
(21762) |
| Generally
speaking Boxford South-Bend parts interchangeability follows the "if
it looks as it if will fit it will fit" rule. All major dimensions
are the same but there are some detail differences and obviously you
need to be reasonable about what you are doing. Mixing Boxford and
South-Bend head and tail stocks on the same bed is unreasonable but
putting a pair of one make onto a bed of the other is quite
practical. Carriage, apron and cross slide assemblies can be mixed
with gay abandon provided you pay heed to certain minor differences
but switching internal components from one breed to another is
risky. Main hidden thing to be aware of when switching carriage
stuff is that the power cross feed gear size is different so you
will have to split the feed screw. Obviously the Boxford feed-screw
dials are bigger and the mount / thrust bearing assembly different
but they will fit with a bit of simple work provided you attend to
the screw. Boxford top slide feed screw and dial is pretty much a
straight retro fit but again, the South-bend screw wont fit the
Boxford dials. Frankly its best to fit the whole top slide. Cross
slide and top slide feed nuts interchange. When I did a Boxbend (or
SouthFord) hybrid I used a complete Boxford saddle assembly with the
South Bend apron which worked very well once I had attended to the
feed screw drive pinion. As the Boxford screw was in better shape I
had to split it twice and braze the SouthBend pinion in. If using a
South-Bend screw you only have to fit the longer tail needed for the
Boxford dial assembly. QC gearboxes may be more of a problem. The
intrinsic centre height and bed spacing is right but there may well
be differences in bed shape which prevent a straight swop. This is a
known problem when retro-fitting QC boxes to non QC Boxford not
just a Boxford South-Bend issue. Fixing holes will need sorting too.
Change gears are a straight swap. Clive (21764) |

case, but the Boxford dials I bought fitted straight on to my SB
feedscrew. However, being larger diameter I had no datum mark for
the micrometer dial, so I turned a brass collar to overfit onto the
original thrust collar, held in place with a grub screw, and scribed
the datum mark on that. Len (21767) |
| Thanks
Len for reminding everyone that fitting Boxford dials and a datum
carrying collar is an effective way of upgrading small dial
South-Bends into something readable. To the best of my knowledge
there are no year of manufacture problems but I think Boxford dials
do vary slightly in thickness so you may need to shim or trim to get
things seating nicely and the handle tight with no play. I've always
changed the whole thing, mount and all. It means more mods but it
gets you a roller thrust bearing and, on the cross slide, the extra
length of the mount is a great help in keeping the handle out of the
way. The two socket head bolt fixing on the Boxford assembly is
better for taper turning types as its much easier to withdraw the
feedscrew. Its a shame to cut out the threads from a South-Bend
cross-slide though. By far the best option is to get a Boxford slide
as well or fit (as I did) a new T-slotted unit. If you travel this
route go the extra yard and fit a hefty, square turret type, rear
tool-post for the parting tool and knurling tool. The extra weight
helps tame chatter and makes it easier to get a good finish whilst
having a correctly set parting tool ready at all times is just plain
brilliant. (21788) |
| If you find a good
Boxford my recommendation is to grab it and ask questions later. I
have a SouthBend B9W w/HMD (late 30's/early 40's) and a Boxford 9" A
Underdrive (early 60's), so if I discover any surprising
compatibilities, I will post them. I'm thinking of messing about
with a gearbox transplant onto the B9W as bed lengths are identical
(just to see if it works). I won't be boring the third screwhole
thru the ways though - I think there may be other methods such as
clamping the leadscrew end of the gearbox onto the outside way. If
developments get interesting, I will post them. Tim (21794) |
| 10K parts fits 10L? |
| Anybody know
if a 10K tailstock and steady rest, will fit a 10L (heavy 10)?
William (19218) |
| I believe the 10L ways are
wider and you have to change the base. JP (19219) |
| Yes, I know, and NO
the will not fit. The beds are different widths. Frank (19222) |
| The answer is no, the parts
are not interchangeable. I own both machines. The machines are very
different in many ways. Perk (19223) |
| 9 in/10 in |
| I have a question
involving a 9 in.sb and a 10 sb I just got (yes I'm hooked) is it
possible to put the head and tail stock from the 10 on the 9. My 9
in has a longer bed and has all it's drive. It's a model A and the
10 in is missing it gear box. if I do this will my threading
abilities still be the same on my 9 with the 10 head. The teeth on
the 10 in. head appear the same and have the same number of teeth.
gregg. (19663) |
| Every thing is the
same except the center height, you also need to use the 10 compound
rest. Boris (19665) |
| Heavy 10
pedestal bed & cabinet bed- interchangeable? |
| I am considering
changing out my worn bed for a less worn one and was wondering if
the earlier heavy 10 bed that originally mounts to the pedestal and
legs can be used with the headstock, dual lever gearbox, saddle,
feet, etc. of my early 50s cabinet style heavy 10. Does anybody have
experience with this? Mark (20892) |
| I am not sure
about the leg model but I do know I bought and had to return ship an
old heavy ten that was a rear belt drive and it would not work. I
didn't even know they ever made a rear belt model Heavy 10. The bed
has to have the casting made to accept the belt dropping through it.
I would guess that any heavy ten that had the motor below would work
but before you pay big shipping bills like I did use some good
measure comparisons with the guy you are getting it from. Also the
gear box when we were building one up for fun a couple of years
back. If the bed came from a different gear box like the single
lever the bed is not drilled for the box mounting right but I think
this would be easy to fix. Might add don't pay to much for a bed
unless it is excellent because you can have your bed reground like
new if you are getting to much in it. Grumpy (20894) |
| If you regrind the
bed, don't you then have to worry about shimming the rack and making
sure the QC and all that lines up correctly since you will have
lowered the headstock and saddle? Kevin (20901) |
| Of course you also
have to worry about this (and possible removing material rather than
shimming) if you swap beds. (20902) |
| Swapping
headstocks between similar models? |
| I am
rebuilding a 9" Model C that is in good condition except for the
headstock; it has quite a few chipped teeth and the bearing shims
are missing, not to mention a few odd holes drilled in the castings.
In the parts collection I have a headstock from 9" model A that is
in great condition. Can the Model A headstock be used as a direct
substitute for the Model C unit? I am most concerned with the
bed-to-centerline distance and am hoping that all 9" headstock
castings are ground to the same finished dimensions. Both headstocks
are identical in appearance. Tj (21186) |
| If you change any
headstock there is a good chance that the tailstock will not match.
I was once told that they are a matched set and that the tailstock
was bored from the headstock As long as the tailstock is lower there
is little problem as you can shim the tailstock up. The headstocks
are more or less identical between the C and the A. I have swapped
headstocks on my C with one I bought on E-Bay. ( I messed up the
bearing surface.) I needed to shim the tailstock about 0.012" Jim B.
(21187) |
| Yes you can, but
you should check vertical separation between headstock and tailstock. tj (21193) |
| Heavy 10
compatibility |
| I have a SB heavy 10 that is missing a tailstock and
carriage. I was looking at a Logan lathe over the weekend and it
looks so much like the sb I was wondering if anyone knows if there
are other tailstocks or carriages that would fir the heavy 10? might
be a dumb question, but like I said I'm new to lathes. jeff (21394) |
| The short
answer is no. Logan's use a combination prismatic and flat ways for
the saddle and South Bends use two prismatic ways. They are
completely incompatible. The tailstock I'm not sure but I wouldn't
think so. At least, not without "fitting," that would involve skills
and equipment unlikely to be available to a newbie. Check with Plaza
Machinery or Sobel for the parts you need. Very likely, they will
have what you need. Webb (21400) |
| Threading Dial
for Heavy 10 |
| Anyone out there
know about interchangeability of the threading dials for the SB 10R? I'd like to find one for my Heavy 10. (21518) |
| I used one from a
Sheldon lathe, just needed to make a simple mounting bracket. One
from most any lathe with an 8 TPI lead screw should be adaptable.
This includes most American lathes. JP (21522) |
| Lathe Bed
interchange |
| I have a 13"
SouthBend lathe that I got at NO cost. It runs and works good as far
as I was told, it came out of Allis Chamers corp. The lathe bed ways
are in very bad shape in the first 12"(main working area) and the
saddle ways are also bad. Serial# on this bed is 159034. Pre 1947??
it has a single lever feed gearbox. Now I know a guy that has a good
bed and saddle with the rest of that machine parts out that he is
willing to part with. This is a newer lathe with a bed serial number
of 11343tkl14 and has two lever feed gearbox. Will this bed work out
with my headstock and single lever feed gear box is what I'm looking
to find out. Joe (26194) |
| I'll defer to
the more knowledgeable members of the group, but I don't know any
reason why it would not swap. You may also want the tailstock if
yours is worn relative to the headstock. George (26195) |
| The headstock
should fit the bed. I have a double lever head stock 2 1/4 on my
single lever bed that had a 1 7/8 headstock. But the reverse lever
and covers are different as well as the lead screw. (26196) |
