That's what I meant, Mark. I changed blades on mine last night and noticed the blade has pressed a groove in the center from where it has been riding. The blade sinks pretty far into the brush's wire bristles. Last night was the first time I opened the back and I found some chips in there, but not bad after using it for a year.
The brush holder on mine isn't near as pretty as the one you made.
yea, the brush lasts about a year. I just have the brush touch the blade enough to turn it. The brush lasts longer that way.
