FWIW I just measured the X leadscrew diameter, mine appears to me .926 or 23.52mm, with 10 TPI, or as close to that as I could figure. Half nut appears to be brass, hard to see under there, very greasy.
Only reason I think it is an RF-31 is the speeds are 150-3000, most RF-30 i’ve seen are 120-2500. And my speed chart on top of belt guard has #31 of it.
zdiaz & C-Bag thanks for the info. I guess we’ll keep looking into this.
Some newer machines can be a mystery, unlike my 80 yr old SB 9C.
So it goes.
