Re: [atlas_craftsman] Re: Slow Speed Adapter
- speaking of crazy coincidences,I bought , at obscene cost, the set of pulleys you need- no use to me- I have more than $50.00 in them. I will send them to you on approval. Please send details of shipment to: Jonathan Bateman, 25 Ivy Drive, Apt. 41, Keene, NH 03431 or to above email.

I went back out and looked at the drill press, I know my dad or
grandfather replaced the motor at one time, the motor pulley is a 3
groove while the spindle pulley is 4 groove. I've gotten ahold of an
old dunlap 1/3 HP motor which is what was originally on this press.
My coworker just told me this morning that his 150 has the slow speed
adapter and he can go down to 72rpm. He's going to pull it and we'll
make a copy of it. It can't be too hard to make. The bearings for the
pulley will probably be the complicated part. My neighbor has an old
atlas/craftsman lathe that I can use to turn the pieces.
- Hi, realize it has been quite awhile but I am currently in search of motor drive pulley for an Atlas Mk2 lathe. The pulley and belt are very narrow like 6mm or 1/4 inch drive. If you still have these please contact me 925-487-7895 e/mail clearsky@..., thanks, Douglas
