I have a router table setup consisting of a jessem-em table and lift with a milwaukee 3 1/4 hp router mounted to it.
I noticed that something wasn't right when a roundover bit with a 1/4 inch shank moved upward while routing, screwing up the workpiece.
I went through the tightening procedure multiple times and felt something was wrong. When tightening the collet, I was used to stopping tightening when I felt it was tight enough. With more power I would have gotten it tighter. Now, at some point, there was something like a 'hard stop' an what point I couldn't have possibly tightened further. As if the shank wasn't thick enough.
Now I seem to encounter the very same thing with a 1/2 " bit: A 'stop' position while tightening and a bit that seems to move up slightly.
The router is about 10 years old, so are the collets.
My question: I can see that collets might get 'tired' after a while - but both at the same time? Are there parts of the router shaft (that the collets screw onto) that might cause something like this?
I am not using anything but 1/4 or 1/2 inch bits, no weird european sizes.
Thanks for any help / opinion
