Hi,
I registered here to share my recent experience with brushes. I own two early bt3000, one of which is in daily use at work (builder). Had a brush failure, and then discovered that they are NLA.
Ordered the (wrong)later brushes, returned them.
I want to keep these saws running, for all the reasons well documented here.
Eventually, I went to my local hardware store and looked at the generic brushes. I saw that there was one which was very close to half the size of the Ryobi brush. So I bought four, sanded them down to size, recontored the radius by sanding on a round surface same size as the armature, and installed two brushes into each brush holder. Two springs, leads, etc. It was a tight fit, but got it in. After all, it's all conducting to the armature. I must admit this was not machine shop quality work, I was experimenting.
Ran the saw for a few minutes with no load, then tuned up the sticky switch , cleaned the shims and guides,(thanks for the tips on shim retainers, I have used the double stick tape with no problems for a few years), then took the saw back to work.
It's been in service for two months now, with no apparent problems.
