Brings back memories from the 1970`s , got about 6 pence each on piecework, brass, copper and aluminium lighting , no gloves, goggles or PPE/H & S, and dropped the blank in with lathe on continuously , working in Birmingham metal bashing quarter/ jewellery quarter.
Fantastic! Any leads you can give about where to get supplies for this type of work would be appreciated. I guess you're using a polyethylene support on the tailstock side?
the tailstock support can be just about anything...UHMW, Delrin, PVC, brass, wood, composite, etc. The spin chucks are shop-made to your specs and the hand-tools can be shop made or purchased. Mostly, everything would be shop made to fit your specific needs
Is it possible to make a stainless steel (3mm thickness) disc into bowl ? I need advice like what is the failure rate ( like how many not cracked bowls out of ten)
Yes, you can spin on any lathe. But lots of pressure is put on the bearings. Little parts like these not so much, though. You need to be able have a spinning rest mounted and you’re good to go. Speed (RPM) is needed, too. So the upper end of the lathes pulleys should be used.
