Blue Chips, thanks much for the reply and the identification confirmation. That helps. I tried to get the serial card or 'build card' from Grizzly but, as I noted, they said that particular card had been lost so they couldn't provide it. That was part of the motivator for this post. The different colors are evident on the machine in different places where the paint is scratched or scuffed or worn away. In some places the orange shows thru and of course the green is all over it. But the original machine gray is evident under all that. So I am still in the process of slowly removing all those layers of paint so that I can get it repainted. As for the collet adapter sleeve, I don't have it. Just the pieces that are in the photo (other than the collets of course) Going to have to locate one somewhere. Greg

Afternoon all. This is my 1st time posting on this particular group, though I have been a part of the Rockwell Milling Group for some time. I recently purchased a South Bend 10 Heavy and am looking for some opinions on the machine specifics.

Someone in the distant past painted it an orange color (?) and someone else in the more recent past painted it green. I am in the process now of trying to remove all that old paint & repaint it the original gray color (as close as I can) using Ford Tractor Light Gray spray paint. So I have not powered it up yet. There was quite a bit of rust on the bare metal parts. But I have managed to get most all of it off. (Electrolysis is our friend)!  It only came with a 3-jaw chuck (Cushman 8”) & the tailstock of course. No 4-jaw or steady rest or follower rest. It did come with a set of 5 C collets & rack.

And also has a hand lever collet closer attachment which is missing some parts. (Missing the Sleeve, Knock Out Nut, Spanner, Shoe, Spring, & Snap Ring). I have no idea where to acquire these parts so if anybody out there can advise, I’d appreciate it. The shaft of the closer was pretty badly rusted & pitted, but the rest had only surface rust.

I ordered a Serial Card from Grizzly. But was later notified that that particular card “had been lost and was not recoverable”.  (Figures).

I have tried to lock down everything I can from the various South Bend as well as vintage machinery sites based on the Catalog # (CL187R) and the Serial # (11612 RKL). The vintagemachinery.org site under “10” regular lathes 1947-1983” shows that serial number as being made between 1959 and 1960. So, I assume that’s correct. The spindle thread is 2 1/4-8.  It has a 4-1/2’ bed. So if I’m deciphering this correctly, I am almost sure it is a 10 L Heavy, with a large spindle hole (which measures 1.400” and the spindle nose measures 1.600”). Does that sound correct? (The 10 L part).

As the photo shows, the cabinet it came with is the “welded steel floor leg model”.  I don’t know if that indicates that it is a “tool room model” or not (as I have seen pics with that cabinet and they were tool room models). But in the Catalog number (CL187R), there is no “8” between the CL and the 187 and I believe that is the “tool room model” indicator. I don’t know.

The brass chart plate which is (supposed to be) mounted on the outside of the cone cover is missing and was approximately 2-1/2” wide X 5” tall in size. I don’t know what that chart was & can’t seem to locate any close up pictures that would help identify it. Can anybody advise what it should be? Is it the lubrication chart (Chart #441-3) perhaps? I see different brass charts online, both originals and repros but don’t really know which chart would apply. On the underside of the cone cover is the head stock bearing adjustment plaque which is intact (though slightly painted over by the previous owner with a green fetish).

Among the various pieces of parts I found loose in a cardboard box was a gear that I can’t identify. I am wondering if it is related to the missing gear from the hand lever collet closer?? Perhaps someone out there can enlighten me. Will try to include some pics. It is a 1.000” wide gear. The OD is 2.997”. The ID is a little more difficult because it looks as though it has been worn on one side. It measures 1.940” but the worn side measures 1.949” The inside has a
.193” (3/16”) keyed slot. The gear has 40-teeth. I don’t know what it is for. (With my luck, it’s the ONE PIECE the entire lathe depends on and it’s laying in a 40-year old cardboard box).

Another item in that box (which I can’t identify) is a small plug. (Pics hopefully included). It has a step down on its OD. The measurements are: (large) OD- 1.250. (small) OD- 1.000. Thickness- 0.750. And the ‘step’ measures 0.400 on the large OD and 0.350 on the small OD. Anybody?

The electrical control box on the rear of the machine of course has a cover over it, but is missing one of the two ‘RESET’ buttons that should be there. Anybody have a clue where I may find such an item (or modern equivalent)?
Also missing is the thread dial. Threaded mounting holes are there. One even has a hex head bolt in it. But no dial. Just noticed that one. I only cut threads on a rare occasion, but will try to locate one to complete the lathe anyway. The only one’s I’m seeing right now are the 3-D printed ones. (Outside of the rare one I find on EBay that a price gouger is showing for a zillion dollars). Hate to disgrace this fine old machine with a 3-D version, but anybody out there with any experience with these 3-D ones? Are they worth having or should I keep looking?

So, it appears I’ve got a few parts to find.  Thanks for any help!  Greg

The ID is 3". The OD is 12".  3/4" thick.

Mike,

 

What’s the center hole diameter and thickness of these wheels? I have a Dumore tool post grinder, that uses 3” wheels, 3/8” hole. These look to be 1”’ish. If the prices is right, I could make up some adapter flanges.

I would like to know if a 4" tool post grinder will work properly on a SB 9"?

I have one sold by South Bend that I would like to rebuild and use, but I hate to waste my time on it if it is too big for my lathe. My South Bend literature makes no mention of size recommendations. It looks like a lot of weight to bolt onto a 9" lathe compound.

If you look at the tooling dimensions drawing you might notice that there wasn't a lot of variation in swing over the compound until you got to the much larger lathes. The 9" workshop, 10K and the "heavy 10" had almost identical swing over the compound. Larger than that swing over the compound increased less quickly than swing over the bed.

So, it wouldn't surprise me much if one tool post grinder worked with many or most lathe models.

It came in parts, so I have not had a chance to mount it yet nor did I want to spend the time and money rebuilding it just to stick it on a shelf. Comparing the centerlines is a good idea as far as determining fit. It's a little weird that South Bend sold these without any recommendations as far as the proper size grinder for a given size lathe. I looked and can't find a thing.

The Dumore link recommends a Series 44 grinder for lathes with 8"-14" swing. Series 44 grinders weigh 35# and use a maximum 3" diameter grinding wheel. The South Bend unit can use a 4" wheel and probably weighs about the same. I guess my 4" grinder should work okay. The advantage of the South Bend grinder is the direction of rotation avoids having to run the lathe backwards and risk unscrewing the chuck. 35# sounds like a lot to mount on the compound, but I suppose light passes are part and parcel with a grinder anyway.

Once I rebuild it and mount it, I will follow up with any info that might be helpful to others.

Thanks.
