This project definitely comes out of left field...
I have a Jet Performax 16-32 drum sander that just predates the addition of a SandSmart controller. When I first got the sander, I looked into swapping out the controller. Well, the box of parts has sat for a long time, but I got it done this past weekend.
SandSmart is the controller that runs the conveyor belt. It allows you to set whatever variable speed you want, but if you set the feed too fast for the drum, it automatically backs off the conveyor speed to keep the drum at full load, but not pop a breaker. For anybody who has popped a breaker by taking too much off a board or hitting an unexpected high spot during flattening passes, you know why this controller can be a big deal. When the breaker pops, the conveyor stalls almost immediately and the drum spins down very slowly. The heat of the drum slowing will always leave a very large burn mark.
The "doesn't pop the breaker" benefit is the most touted, but not the best reason in my mind. Drum sanding is slow, it's boring. I like the idea that on the first several passes to simply 'hog off' stock, I can set the speed much higher than it could handle and let the SandSmart controller back off the speed to the maximum speed allowed given the abrasive, stock, and amount you're trying to take off. That's why I want SandSmart.
In this video, we take a tour of the drum sander insides if you haven't seen one up close. Below the video is a list of parts you'd need to accomplish this. They are all available from Jet's replacement parts program.
Even if this upgrade doesn't interest you, if you have an older pre-Jet Performax drum sander, you might want to consider ordering the new dust hood with the 4" port versus the older 2.5" port. The stock number for this new dust hood is 80-2002. Depending on your older model, you may have a knob to open it (like you see in the video thumbnail) or a D-shaped handle. If you want the knob (which the replacement dust cover is drilled for), the knob is 80-3137 and the corresponding latch 40-3168. Note that the SandSmart controller assumes a 1.5hp motor. If you have an original Performax, you may have a 1hp motor, which will draw a maximum of 8 amperes. The 1.5hp motor will draw a maximum of 11 amperes. SandSmart's hysteresis is based on current so the 1hp will never get in the self-regulation range of the controller.
