Looking for options to add collets to my very old SB 15x8 lathe.? I have seen the recent posts on using a backplate and ebay/amazon ER40 chuck.? Wondering what was the original taper in the tube of my SB model 37?? Is it morse or what I believe is SB propietary??
If morse, then I would need a drawbar and nut for the tube.? As close as I can tell the threads are 2-1/4x6, not 2-1/4x8 like the newer lathes.
I have multiple chucks and backplates if I want to go the ER40 route.? I am a beginner as to working with lathes.? Shop class 55 years ago.?
