How to stop a ¼" bit from moving up in its collet?
I have the older model Triton ½" router in a Triton table. All is good with ½" bits, but I have an upcut ¼" bit that I use in a collet. Regardless of what I do the bit moves upwards in the collet, i.e. starts to cut deeper as soon as I start moving wood through it (collet does not move.). It can move up 3/8" already after 6" of cutting, and it's driving me nuts. I've tightened the chuck hard as I can, used mallets to tighten it, used higher and lower speeds, used different brands of collets, but nothing helps. Haven't tried locktight yet, but will. Anyone had a similar problem, or have any tips?
Thanks so much,
