??? ??? Verify your spindle threads & there is plans in the
files section to make a ER40 collet chuck . Nice thing a one piece
ER thread on collet chuck is it cut's down on the length of
stickout on the spindle & you can also feed stock through the
spindle , but make sure you have a outboard spyder if you have
long material .

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.?
