Let me just start by saying this is all a little above my head. I recently purchased a Bosch 1276D Belt Sander. The label rates it at 12.5 amp with an input power of 120vAC at 60hz. I've been digging for days, trying to find ways to juice this thing up a little more. I'm trying to get it rdy for my first belt sander race and will be running against lighter, and faster Makita's and DeWalts. In my research I have heard about Full Wave Bridge Rectifiers which should be able to take the standard 120Vac 60hz and take it to around 169 Vdc 120hz. Needless to say I don't know much about altering circuitry so I'm trying to find some help from people on what rating of bridge rectifier to buy and how's I go about hooking this thing up. I've also read that it's a good idea to apply capacitors to the bridge to smooth the DC output. Also, is this DC voltage going to smoke my belt sander's motor and what effect is doubling the hz going to have on the motor. The average race last between 2.5 and 3.5 secs...so I wouldn't be running it very long. But, for lining up the sanding belt and other various pre-race preparations, it would be nice to be able to switch the rectifier off when I don't need it. Any suggestions would be much appreciated. Don't worry, any help you offer would not be considered enabling me to cheat. Multiple racers that come to this event every year, juice there's up but aren't willing to divulge their secrets. I'm just a simple carpenter lookin for a little help. Thanks alot.
