Hi Bobpat,
the Super Adept lathe is quite a simple hobby lathe, check out this link – http://www.lathes.co.uk/adept/
I dont think they ever made a collet set for this lathe, I did have one but sold it again as I couldn’t find parts for it other than a 3 jaw and 4 jaw chuck. Check the headstock on it too as these often get overtightened and broken and are welded back together. I have a four jaw chuck for one of these but it is now mounted onto an 8mm collet to use in my watchmakers lathe
