Lathe tool - what is it?

[Jswain]

Just picked up a new to me south bend 9c 1938 and I can figure out most of the tooling except for a couple pieces but I figured I would ask for help on this one as I can't find anything like it but I'm not a lathe guy.

It has an mt2 shank and the face is roughly 2" across, a bit of pitting and roughness on the back seems like it maybe homemade or modified. 1/4"ish hole in the center which goes in about 3/8" of an inch....WHAT AM I

Added a couple more photos to last post of the almost finished project

Drilling crotch....fits in the tailstock.

It looks tapered in one pic, but straight in the other?

Rest of the lathe & tooling that came with it...fairly dirty but mostly grime from sitting not being used. Seems tight and no marks in the ways/everything moves nice and smooth, can't find any chipped gears.

It's at least getting a partial restore if not a full

That was quick, thanks!!

I can see what you mean, just an illusion though definitely mt2

Looks like a good one! Wish I had all that stuff for mine. Looks like an annoyingly noisey belt with that metal clasp. Some SB owners glue the belt or find one the right size and pull out the shafts to install.

Google ”Flexco Clipper Lacing”

I think I will likely go with a serpentine belt, I'll probably wait til I get a wick kit then pull that right apart so I can put one that isn't cut on it.

They actually used a strip of rafter tie cut to join the belt lol, nifty but noisy

I was kind of anxious to go see it because it didn't have any of the tooling in the ad. When I pulled up and seen a box full I was quite relieved

Steadies, check
3&4 jaw chuck, check
Change gears, check
Tail stock, check

All the expensive parts present. Very good start to a lathe.

no neat sig line

Automotive serpentine belt worked quite well on my Logan!

Nice pdf thank you! Other cool thing that came with the lathe was all the original paperwork from 1938, including a couple of written letters between southbend and the original owner. A few books from that era too pretty impressed they have kept them this long

You want a J section Poly V-belt: https://www.mcmaster.com/catalog/128/1236

Have the rest of the stuff sorted out except for these two. Not even sure if they are for the lathe or random things thrown in.

The little tray is roughly 6" long and 2" wide. And the stop clamp? Is about 3/4" with a set screw and markings 4h 42 g on the backside

Looks to me like a stand for a large soldering iron and an old fashioned dumbbell weight keeper, though that would usually have an L handle and not a set screw.

 

[Old Man Roger]

Soldering iron stand for sure, I have one just like it. Not your average size iron though.

 

[RTM]

2nd looks like a dumbbell end holder to me too. Seen some needing a square wrench, never an Allen key.

 

[Jswain]

I guess now I need a bigger soldering iron

 

[lilredex]

Not really, I use mine with these irons.

Well here she is mostly cleaned up. I will probably do some painting in the near future of all the guards/tailstock/saddle etc but everything cleaned up quite nice. Still waiting for a new vbelt but I slipped a one piece serpentine belt on there to get rid of the leather.
I placed it a little far back on the table because my garage is fairly small and busy so I'd rather not hit the lathe with anything

Came with an amflo coolant mister too but it was missing the base, knob was broken and the suction hose was split. 3d printer took care of most of it and then a fitting for a new suction hose was the first thing I made with the new lathe

 

[Jswain]

Found a good deal on a table but needed some work so spent some time on it. Wanted to leave it bare and strip the millscale but after 2 days of soaking with citric acid/vinegar/ quite a bit of grinding I decided on paint lol

Anytime you tilt a camera downward and snap a pic of an object the part that is closer to the camera appears bigger than the parts further away. In this case the narrower tip got bigger and made the shaft look parallel. Not too long ago view cameras were used extensively to correct this issue in advertising photographs. View cameras can tilt the lens board and the film back (plus raise and lower and swing sideways) to absolutely control the shape of objects for correct looking images. Today this is done in photoshop.

Our minds subconsciously correct these phenomena for us so we don't notice these effects in normal life.

Try photographing something symetric like a cigarette package from above while observing it's image on the screen on the back of the camera to see this effect.

I have noticed that while taking pictures of a piece of paper.
