Bruce,
Just offering a word of encouragement ¡ª the very first real thing I machined on my 618 lathe was a 2-step motor pulley. When I bought the lathe, it had all the other parts including the two-step countershaft drive pulley, but the motor only had some Tractor Supply Company single groove version. After a bit of research and advice from another owner, I was able to sketch up the required dimensions and turned one from a 6061 round stock. It took way longer than it probably should have to finish, but it fit up nicely and works like a champ. Moral of the story, it looks a lot more complicated than it really is; if you have a way to use the lathe as is, dive in and do it. You will learn a bunch in the process, and there is a great deal of satisfaction to be had the first time you make something else using the parts you made yourself.?

Thanks all!

Glenn N ¨C Yes, Robert Downs put this file in the files section.

Brad ¨C How can 3-D printing & casting & machining be less expensive than the piece of aluminum?

Kay ¨C Thanks for the Speedy Metals link.

Robert Downs / Guenther Paul ¨C Thanks for the suggestions on how to machine it more easily.
?
Kay Davis / Dave Matticks ¨C 7075 seems much more expensive than the other aluminum choices.

Craig Treleaven ¨C Thanks for filling me in on the edits I make causing problems.? I get the update only daily, so do not have this problem.? The only times I do this instead of a separate post, is when I have grammar or formatting errors.? It seems like every group has different formatting defaults.? And in this group you cannot see what the final formatting is going to look like until AFTER you post.? Will try to be more careful.

So everyone understands, it may be a while before I create this aluminum pulley.? I will update everyone when I complete this or have questions.? Prior to November, I did not even own a lathe, so I am new to this & still learning.? What might be easy to some, is new to me.? I am going to a) wait a little while to see if I can locate an OEM 60-29 pulley.? b) If not, then I will do the aluminum pulley machining.? As was discussed early in this thread, I do not use the drill press constantly & it is working as is. ?So this is not an immediate necessity.
