Bits coming out of collet
I have an old Craftsman 1/4 inch collet plastic router from Craftsman. (red and black housing). I have it mounted to a table and it does pretty good most of the time. However, sometimes, but not all the time, when I am routing a groove or dado, the bit will start to come out of the collet. It has never come all the way out, thank goodness, but I am a bit fearful that it might. I have noticed this using a stright bit, spiral bit and with either a flat bottom or rounded bottom.
The collet is still tight around the bit's shank. I cannot move the bit when I have the router locked as to remove or replace a bit. This seems to happen mostly if I have the bit set just a bit too deep. Too deep seems to be more than about an 1/8th of an inch.
If I am making a rabbit or rounding over, this doesn't happen. It only seems to happen when the bit is completely surrounded by wood. Any help would be greatly appreciated.
Thanks in advance,
If at first you don't succeed, maybe you shouldn't try sky-diving!
