49505RE: [atlas_craftsman] Re: Lathe speeds - halifax 524
- Feb 5, 2008After much messing about, I bought an old tacho off eBay. It's a Starret
tacho quite like this one:
You reset it and pop the end in your spinning chuck. Time it for a minute
and the see how many revs it has counted. The scale on the outside counts
revs (1-100) and the inside scale clicks over every 100 revs.
I have some info for my Halifax 524 if that's any use to anyone:
I didn't change motor drive pulleys right now as it's too much hassle, but
with the motor connected to the smaller pully and Pully 1 being the largest
drive pully (top left) just above/behind the headstock the speeds in RPM
1 - 2000
2 - 1275
3 - 800
4 - 500
Backgear - 85
I hope this info is useful to someone.
