I am at my wits end, the conveyor switch is not working and now the switch for the drums seems to not be working properly. So what I would appreciate is can I get a sense of what I propose as a solution will work - I am going to remove all the switches. I will attach a separate 20amp switch that will power the drums. For the conveyor motor, I was thinking of attaching one of the variable speed controls that you can buy separately for routers. Doing all the wiring I can do no problem, I just want to be sure this will work before I dump money on this. I have had too many projects start to go through the sander only to have the conveyor stop. Thanks for your help.
