I have a lawfully acquired, but less than useful backplate. It has an odd thread, 1-7/8"x8tpi). Which is strange, because I have a lathe with an equally odd, but different thread (2-1/8"x8tpi). . . also lawfully acquired.

Is there an index of lathes anywhere that would be searchable by spindle type? It's too nice of a backplate to sit on my shelf rusting. The shelf space generally being reserved for rough cut scrap that is rusting.
 
I too have a ship load of these oddball threaded backplates and chucks from long ago lathes . :grin:
 
I'm thinkin the Heavy 10s have 1 7/8ths whatever threads . I just measured a Bison up that I know came off the old SB that traveled north . I had posted a thread in the trading section long ago , but it doesn't get much attention . :big grin:
 
Good to know that there is no lathe or backplate theft going on around here, I wouldn't want to be guilty by association. I've just finally cleared the statute of limitations.
