Replacing switches on 3hp General Dual Drum Sander

howgor

So have got to change the switches to my 3hp general dual drum sander. I'll run a piece through and the conveyor just stops. Tried blowing any dust away but that hasn't helped. I know I can replace the switch that will turn the drums on, it's the variable switch to the conveyor that I can't solve. I also don't know if the motor for the conveyor is AC or DC. So here's where I need help. I am going to remove all the existing switches(don't know how to attach picture of switch panel to this). For the drums I will put in a 20 amp safety switch. But what switching should I use for the conveyor motor?? Should I just use a regular 15 amp switch off a 15 amp 120v line and forget the variable speed, or is there some type of variable speed switch I can get?? Thanks for the help.

I am still not sure what to do with the conveyor switch. I was asked if it was ac or dc and I am not sure of that. The switch that was recommended to buy from Amazon was a simple switch for the drums it didn't seem like it would work for the conveyor motor.

I have a Grizzly 3 hp dual drum sander. The conveyor motor is a 1/4 hp IIRC and the conveyor belt runs at 11 fpm. The conveyor is not variable speed on mine. Unlike my Performax, the sanding drums pull the work through and the conveyor resists it.

My suggestion is to call Grizzly and talk to their tech people. They have been very helpful to me in the past. Jet also makes sanders and I have talked to them, and they have been helpful as well.

You don’t have any motor shops around. Having the conveyor at full speed all the time would make it useless in my opinion.
