It's possible the brushes on the motor are worn and need replacing Mimi. Unscrew the caps on each side of the motor, unscrew the brush and visually check. You can tell just by looking. To replace may cost $20.00 each. I've replaced mine twice in the last 16 years which only takes a few minutes. The brushes should be available through Seyco or order them through a local electric outlet which I had to do. I now keep a spare set on hand eliminating any shut down time. Good luck.
Well done Ralph. Freeing up space on the work bench is a good thing alowing other items waiting in line to get on ... Lol. I like the storage on the stand. The self looks to be the proper size to hold a cold one, and maybe two. Anyway, very nice.
My shop is well insulated keeping the heat out during the summer months. During the winter months I maintain the temperature with a small electric heater so I'm good to go all year through.
