I am converting a cheap little 9” bandsaw I had laying around, via a speed reducer, and matching motor. The end result will be a small bandwidth able to cut smaller steel and brass pieces. I have other ways to cut bigger stuff, including a power hacksaw made by machinist at home in the 50s. It’s really cool piece of vintage machinery. It uses an weak motor that likely came out of a washing machine, but makes beautiful cuts through 4” round stock.
I digress, back to the point.
The output shaft of the reducer is 7/8”. The old bandsaw motor was 1/2” and has a gear on the end feeding the bandsaw drive belt. I need to remove the gear and place it on a new shaft and then adapt it to 7/8” to connect it the reducer.
I am having trouble finding a premade reasonably priced adapter. I thought about buying 7/8” prekeyed shaft and machining down one end to 1/2”. I never keyed a shaft myself. I would then use 7/8 to 7/8 coupler. However, I am concerned about the key gap causing problems when turning.
As far as pulling the gear.
1) Freeze motor
2) Heat gear quickly
3) Pull with puller
Suggestions needed but please remember on a scale of 1 to 10, I am a -1 as far as skill goes
