I have a 1/2 hp 14" bs and recently was offered the motor out of a 1 hp craftsman. The process or making the switch doesn't seem too complicated... or am I missing something? Are there issues I'm likely to see?
I have looked and it appears the motor on my band saw runs counter-clock wise and the craftsman motor say "CW. Rotation shaft end". It sounds strange I know but I have read about motors not always rotating as marked, but pretty sure testing a motor that isn't mounted to anything sounds like a bad idea.
If I am as screwed as the labels on the motor makes it sound. Is there a way to revers the direction of the motor?
However, you can locate the motor on the other side of the belt and ...walla ....it's turning the belt the other direction. You can also fire up the motor just clamp it on a board or plywood...it will jump a bit when it first starts up, then it will be fine. If the location for the motor is such that you can not turn it around then you are "screwed" as you suggested. If the stand is open rather than a cabinet type then it's possible to turn it around OR you can make a new stand out of plywood, depending how attached you are to this whole project. Maybe replacing the motor with a reversible direction type would be easier...I donno?
If the new motor speed is 3450 RPMs, and the old was 1725 RPMs, reduce the motor pulley size by 1/2 or increase the machine pulley by double.
If the belt is fairly long like it is for older saws you can get a slightly longer belt and twist it in a figure eight which will reverse the direction. It's rough on the belts though and should only be done if no other way will work.
