I have a Dremel 300 which I use for drilling my printed circuit boards. I have the drill stand that goes with it.
For years I have not had a seconds problem with it.
Yesterday it just stopped, so I checked the brushes and they were almost non-existent. I had some made here and I fitted them.
When the drill was turned on it made a strange sound but was turning, I assumed that the brushes needed to be run in. However the drill got very hot. So I waited for it to cool down and then opened it up. There was lots of fine dust which I blew out and then basically I cleaned everything I could with isopropyl.
When I reassembled it the switch now does not work.
Can you give me some advice on how to go about repairing this machine. I would be happy right now to bypass the switch and buy a new one. At least if I get it running I know nothing else is wrong
