I am not sure if this is the correct forum but I need advise on choosing the right material to make a new shaft. I replaced the 2 bronze bushings that support the shaft that holds the step pulleys that drive the spindle from the motor. The shaft is worn pretty bad where it rides in the bushings and is chewed up where the set screws sit. Should I make the new shaft from 3/4" drill rod or just use some 3/4" round stock from Home Depot. Also should it be hardened?
It's a 12" Craftsman Atlas lathe.

I wouldn't use either. Get with Pacific Machinery and Tool Steel, and get some 3/4 1040 TGP. They call it 'Arrow 10'. It's just for that purpose. If you feel like overkill, buy 'Acralloy' instead.

It's not expensive.

I finally finished the new shaft for my lathe today. I used 1045 T G P from Speedy Metals. This project required me to cut my first key slot which worked out perfect. It didn't occur to me to take pictures while I was making the new shaft, but here is a photo of the lathe back together and a photo of the old shaft
. Thanks for the advice!

Thanks, this time we can see the pictures. Looks good. Nice little lathe should work a lot better with the new shaft.
 
Nice work! 1045 TGP is very appropriate for shafting of this nature. Tough, but easily machined. For high stress situations, 1144 Stressproof fills the bill. Still pretty easy to machine.
