I have decided to get rid of the 7.5 electric motor, just not enough power.  I have already purchased the replacement....it's a 65 hp wisconsin engine.  I know, I know it's big but power won't be a problem soon.  It's in good shape and plenty of power at lower speed.  1600 rpm is around 42 hp so I think I'll size my new pulleys for the 1700 rpm range, should save a little gas and less work on the engine.  Let me know what you think!

Wow! That's a lot of ponies. Is your mill designed to handle the weight? I've always thought that if I were going to build a bandmill, I would build one using an old circle mill track and carriage. Mount the band verticals where the circle mill used to be. Just thoughts tho, never gunna happen.

Yeah, it'll handle the weight but I do have to modify the top of my rig in order to raise my saw head as high as I would like.

I suggest running the engine at it's peak rpm. Making it pull at idle will lead to overheating, the fan needs to move air.

And to think, I complain about feeding a 20hp. To get the most out of all that power, you might consider 2" bands, or at least 1.5"

Duane,do you have any parisitic loads on your electric motor like a hydraulic pump,really with good electric service a 7.5 hp motor should handle things.Your not turning your band too fast are you.I converted my bandmill from engine to motor and found I was running the band too fast.Its always best to put auxiliary loads on a seperate electric motor if possible.Be aware you will have exhaust fumes to contend with after the convert.

No....the only thing the motor is pulling is the band.  I have got problems with the motor anyway, it was a new motor that has been dropped but repaired but it is blowing start capacitors.

They either are not large enough or the start switch is damaged .
