Hi everyone,

Thought I would share the refurbishment I did to my little south bend 9a last year.

I live on the Canadian west coast, which is a bit of a machinery desert. But I did manage to find this South bend 9a lathe (built 1953). It was used as a high school lathe, then given to the shop teacher upon his retirement, I bought it from a friend of his who inherited it.

Here's the day I brought it home:

The lathe was in working condition when I got it. I did one small project with it before tearing it down. Most inportant the ways were in really nice shape. Unfortunatly the chuck was REALLY stuck on the spindle. I also liked that it came with an original chip tray and cast iron stand.

I had my phone die so unfortunatley I lost most of the restoration pictures. But I will share what I still have.

I tore the lathe down into its sub assemballies.

I removed 7 layers of paint from the bed and stand until it was down to bare metal.

Next I put 2 coats of expoy primer, followed by 2 coats of 2 part urethane automotive paint...

The ways had some dings near the chuck (being a school lathe) but the flaking was still faintly visible down the whole length so I will leave them be.

Here's the cast iron stand, I added a steel 2×4 (1/4 wall) between the two legs rigidity as well as a tray near the bottom, also made with a thick walled frame. I also put some vibration dampening feet on it (hockey pucks).

I most of the pictures of the rest of the restoration but I took apart each sub assembally clean, stripped and repainted them. I also replaced all the felts, wicks and wipers. Additionally, I replaced on gear with a chipped tooth and replaced the bronze nut on the cross slide and conpound. I also had to buy new oil cups to replace the broken ones To get the chuck off I made a tool that clamped the spindle along its hole length then built an attachment for the chuck back plate which had a large bar attached to it and I was able to get it off.

Gear box repainted with a NOS threading chart ready for for reassembally

Beautifully done. Congratulations on all the hard work. Btw, I noticed the (I'm guessing Craigslist) powder coating oven! Sweet

Thanks it was a fun project.

Yes, I do quite a bit of powdercoating for myself, friends and an occasional paying job. The oven came out of my home some years back when my wife and I replaced it with a new oven. I think it is a mid 1980's vintage, but still operates perfectly and is great for powder coating small and medium sized stuff. One day I'd like to have a much larger oven but for now this one works well and it was free.
