Default Overhaul of another South Bend, a light ten

Here's how the freshly oiled and cleaned light ten looks at this point.
I will post some photos of how we got here in a later post.
I wanted the cabinet darker and the lathe more towards the beige, but I don't give a rat's a$& .
Leveled and set in it's permanent place...



Another look.



This is the variable frequency drive that handles the 1/2 HP 3 phase motor:



I hooked it up temporarily, but never got to making the nice controls I meant to make...



This is a carriage stop and a holder for a 2 inch travel dial indicator.



And this is the home brewed threading dial. It awaits painting of the engravings (Lacquer Stick -- it's in the mail -- thanks for the pointer Gail in NM)... I should also change the setscrew to a shorter brass-tipped one... Oh, well, temporarily it'll do (will be there next year )



What I absolutely hate is the lantern style tool post.



Which is going to change to an under construction piston style quick change tool post... Here's the body. I stopped the boring operations as I was getting tons of chatter, and I decided to make a decent boring bar and a decent boring bar holder. When I do, I'll resume construction...



take care,
tom in MA

OK, some photos of the overhaul.

I had never operated a lathe bigger than a Sherline (heck any other lathe other than a Sherline... ). I decided to get myself some old iron. I went for a light ten (SB10K).

This SB10K was used in a high school machine shop. The clutch was stuck, so an apron dismantling was in order. Apart from that the machine is in OK shape - at least by inspection. Take a look at the ways, scraping marks have vanished near the headstock. The depression is 0.002 on the operator side, and 0.001 on the opposite side.



another view ...



Apron with almost all gears and clutch removed...



Various gears in a bag with acetone and carb cleaner for degreasing... The carb cleaner is some nasty stuff, but works tremendously well.



more pics to come...

Gearbox disassembly almost done...



Quick change gearbox gears getting degreased...



Headstock, cover and back gear removed...



Spindle removed...



Spindle, bull gear, thrust bearing, cone pulleys...



Removing the cup oilers...



Degreasing in a few liters of petrol and half a liter of carb cleaner...



Clean to the bare metal...



Masked bearings and surfaces not to be painted...



One hand of light beige industrial grade Benjamin Moore paint...



You get the gist...

take care,

tom in MA

Very nice work, Tom.
I rebuilt a SB9 40+ years ago. I did not do nearly as nice a job as you have done.

Tom;
Nice job, good to see how others have tackled this work. I'm about to do the same to a 9x20 I just found, painting is my least favorite task. I'll be stealing some of your de-greasing methods! The best part of your labour's is the racing stripe on the back wall !
Cheers
Garry

hey Gail,

I enjoyed the job cause I learnt the lathe inside out. Painting was a stupid choice on retrospect. I do not care for looks in general. The thing would not rust.

The problem is that even 3 months after painting, the paint is not fully cured. It is dry, but you can very easily scratch it. It's supposed to withstand scratches though... Oh well, if I were doing it again, I'd use Rustoleum. Like most people.

Garry, good luck. Me like the stripe - anastasia does not love it tho ...

take care,
tom in MA

Great rehab job Tom. I need to do the same with my Heavy 10, and it is good to see you tackle yours.

I like the paint scheme also. Atypical, but very nicely done.
