I’ve been using these HF brass guide bushings for a couple of projects and they’re great. They work beautifully when using spiral bits and a jig.

However, I need to tighten the collet every so often, I assume because of the vibration of the router.

I purchased additional base plates for my router so I pretty much have one dedicated to the bushing I use the most. Aside from simply crazy-gluing the collet, is there any other way to keep it secure? I was also thinking Locktite.

Go to the box store and find a rubber oring that fits over the threads. My whiteside inlay kit came with one, and I have copied the idea to my other bushings.

In defining “thread” there is a tolerance that defines a small gap between the bolt’s thread and the nut’s thread. Perhaps HF increased that gap.

Epoxy, Locktight, crazy-glue, etc.. tend to be of a more perminite nature. If you want to change bushings you would have problems removing the old size bushing.

I would try to close the gap with a wrap or two of tape, like what a plumber does with iron pipe. This would help fill in the gap and yet allow you to remove the bushing.

Teflon tape? Cheap solution, and removable.

I used to have this problem and use a spring washer made for this problem. Several places including MLCS sell them for about $6 for two.

The teflon tape works well, as does the O ring. I also have a bushing nut that has locking screws built in. I think it came with something, maybe The Dado Wiz tool. You can buy them, but they are the more expensive way to solve the problem.
