How does climb cutting apply to using a dovetail jig? Besides a good backer board and sharp bit, you’re at the mercy of the wood, huh?

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,
Dave
Make sure router bit is the same diameter for the whole length of the bit in the collet. Do not sink the bit all the way down into the collet but leave the bit sticking up an 1/8" from the bottom of the collet to allow for bit heat expansion. Make sure not to tighen down on the flare taper of the bit near the cutting edge when tightening the bit in the collet. Set the depth of cut more more than 1/4" on each pass or sometime the bit will ride up from the force of the cutting action in too deep of a cut. Good Luck! Handymanbill

I have had that happen with my Triton. I had the bit migrate a couple times.
But one day the 1/4" shank bit came out - and flew across the garage.
. . . and it can only have the Grace of God that it did not head my way.
I solved the problem easily.
A. I do not ever, ever try a 1/4" bit in the Triton.
Nothing I tried made any difference.
B. I now put the 1/4" shank bits in the Porter-Cable router.

I have a bullet that came into my airplane cockpit one day in 1967 . . .
There are just some things it is better not to try twice.

I thought this was a common known problem with triton. I didn’t know about it until I was routing my rail and stiles for a panel after spending a fair amount of time getting my mortise and tenons spot on. Frustrating and scary at the same time as you have a spiral bit moving up the collet. I went to an aftermarket collet and it helped. It’s a 4 point collet. Maybe eagle but don’t really recall brand. It definitely should be a triton recall item.

I see Musclechuck has collets for the old style Triton (#8) and the new style (#11) https://www.musclechuck.com/compatibility/# That would solve your problem with holding 1/4" bits. The Musclechuck holds 4 times better than any standard collet and is easier to change bits with, especially for table routing. I went to one for my Hitachi M12V2 which I have in my table. I was having problems with bits getting stuck in the collet which is the same as the Bosch 1617 and many DeWalts. No issues since using the MC.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Default How to stop a ¼" bit from moving up in its collet?

I purchased a Triton Router along with my Sommerfeld Fence probably 10 years ago. It worked fine with ½ bits, but ¼" bits were hit and miss as far creeping up. Most bits would only move a millimeter or so, but every carbide spiral bit I tried pulled up before I could complete a dovetail. Sommerfeld send me 2 new collets and neither of them made a bit of difference. It was like a screw backing out. I returned the router for credit and bought a Bosch. That solved the problem.

I’m just a bit aghast at all these revelations of collet cholera - thus far I’ve had no issues with my 1617 but it may still be pretty young compared to y’all’s gear, especially that Triton debacle. Looks like a MC is the only real solution...I stand forewarned.
