What I'm wondering about it the torque. If say I slow down our
bandsaw by 25% would the torque decrease or stay the same. I'm using a
bandsaw to cut brass and have slowed it down with an idler pulley and
its just fine but occasionlly I need to cut material a bit harder and
its wearing the blades. I'm using 1/16 blades and they don't take
running hot too well. I want to be able to switch to my SCR circuit
and dial the speed I want when I have to cut this other material.

Burning out the windings of an AC motor with an scr is a more apt title.

Many bandsaws use what are called squirrel cage AC motors. These are not
amenable to speed control, whether by SCR or any other method. If you have a
small bandsaw whose motor has brushes on it like a drill motor, then you may be
able to speed control it, because it actually isn't an AC motor at all, it's a
DC motor which is universally wound.

I take it you want to slow down the bandsaw's cutting speed to cut steel?

No German Silver which needs to be 25% slower on our machine. Maybe I
need to find another motor thats laying around here
