New to the forum. Hoping someone can shed some light on an issue I'm running into with my router lift. I can set the height I need but once the router is on for a brief time the bit will drop or raise in height. Original lift was a Jet Xacta lift made by Jessum. Thought it was an issue with the lift itself so I purchased a new lift from Woodworkers Supply this weekend. Finished setup this afternoon and the problem is reoccurring with the new lift. Router motor is from a Porter Cable 690 with 1/2" collet. Issue happens with multiple bits. Almost seems as if the router spindle is out of tolerance. Any thoughts?

Welcome Ken. I would have to agree with Stick. The most likely culprit is the collet.

Try putting a small rubber grommet into the collet. About 1/8th thick. Then you can bottom out the bit on the grommet which may help. If that fails, replace the collet. If that fails, get a Bosch.

If it happens with multiple bits then it would appear to be the collet. I had a problem with a 1/2" roundover bit slipping in my Bosch 1617 but it didn't slip with any other bit. Replaced that bit and problem solved.
since then I have replaced my collet with a Musclechuck and it is even more convenient for bit changes and none have slipped.
