Greetings,
I have a 16" Von Wyck lathe circa 1903-1908 that I'm having some issues re: the spindle taper. Based on measurements I took, this was the oddball 4.5MT (1.5" outer diameter).
After much research/google I identified that Grizzly sells a 4.5 MT to 3MT adapter--great!. I purchased a couple of these (why buy just one when you are already paying shipping to Canada) so this is where I have the issue. The adapter doesn't seat smoothly in the spindle with hand pressure, and with slight tapping with a rubber mallet it seems to fit snuggly until you put the 3MT center in it and fire it up. The center has a very pronounced wobble to it.
I blued the adapter, seated it and there is some contact but not what you'd expect to see.
Upon visual inspection, the spindle bore has some wear (scratches etc.), but not unexpected for 110 years old, but no obvious 'nicks' or spurs.
It took a week to find references to a 4.5 MT adapter let alone a 4.5MT reamer (non existent from what I'm seeing).
What are a guys options here?
Is there a possibility that this is not 4.5MT (tailstock is 3MT -- no question)
