Hi.
I have an old TR8 that gets regular use until last week.
The tr8 has a single speed (24000 rpm), 6mm collet.
It suddenly became more difficult to manually control and seems to be
unbalanced when running.

Can anyone shed any light on whats gone wrong with it?

Thanks.

Arthur



Have you done a complete router tune up? There's a how-to article in
Fine Woodworking, Taunton Press, not sure which issue. Have you
checked the brushes? Carefully look for damage? Check runout? When
did the router start behaving that way and what was it doing? Have the
owner's manual?
