    What is the best paint for an old machine restoration.

    Thanks for all the information. I would like this to be a display piece, I don't think it will ever work. So, yes I would like a good polished gloss. I am leaning toward a 2 pack polyurethane.

    What is the best paint for an old machine restoration.

    Astro Skeleton clock.

    Don. That is exactly what I am working on right now. I had a test part that worked really well. When I received the real part , while I was machining the glass the print just floated off. I possibly did not clean the glass properly before I sent it to the printers. I am going to have another...

    Atlas acorn tools shaper.

    Please note; I will make sure every thing is working, but there is no more parts than in the photo. No vice and no side cover. The tool holder in the clapper box is there. It is a dirty gem though. You can make a beautiful restoration job out of it. It is a Myford equivalent in a shaper. I made...
