Hi there woodworkers!
I have a problem trying to use router bits with shank-mounted ball bearing, to shape wood pieces in order to build a radial horns. The wood is 1 1/2" thick ash, and the router bit is 1". I'm using this with a template to make the pieces, but somehow, I'm destroying the ball bearing, which ends up seized and not functioning, burning the wood because ofthe friction, anybody knows what I'm doing wrong? I only managed to shape two pieces before the bearing seizing, and I still have six more to do...

I rough shaped the pieces with a jig saw, leaving about 1/8" extra wood that I have to remove with the shaper. This ash is quite a tough wood to cut/shape, I wonder if I'm trying to cut too much in one pass, but this should only affect the cutting bit, not the bearing??????????

thanks for any advice,

PS - gone now for one week, so if any question, I'll get to them next week - thanks all for suggestions and for your patience if any Q's,

Cheers,
