I am new to the world of templates and flush trim router bits. With that
said, my problem is that the bearing spins with the router bit and burns the
heck out of my MDF templates. Is this supposed to happen or is the bearing
supposed to turn independantly? If this is supposed to happen how do I
keep it from burning up the edges on my templates. It's a Bosch flush
trim bit I bought at Lowe's
Thanks for any help.
No, it should *not* spin with the bit.
It will however, spin with the bit *until* you bring the bearing into
contact with the template edge. At the point of contact there will be a
*small* amount of abrasion/burning of the template until the bearing stops
If your bearing is not free to turn (or not) independently of the bit, then
either it is defective or the attaching screw is too tight or the shoulder
washer is on backwards, etc. If it's a brand new bit, take it back and get
one that works properly.
