Topic tags/keywords: router

I finally got around to setting up and figuring out my brand new old stock Leigh dovetail jig, and the bushing kept coming unscrewed… so of course I dinged the aluminum strip the router rides on and damaged my dovetail bit during the first pass.

Very frustrated.

Any ideas? Obviously I tightened it as much as I can by hand.

TIA

Ummm there is such a thing as a sping lock washer.


Black spring washer keeps bushing tight.

I got mine at MLCS (4th item down on page) as part of a kit, but they’re sold separately for about $7. I’ve made half a dozen projects without it loosening. I don’t unscrew it as it mounts to the Incra throat plate.

Maybe lock tight? I am not much of a router person. I have one but have only used it twice in three years.

I have seen this happen in project videos where the work gets dinged but to have it hit the jig and ding the bit is a double whammy.

Never had this problem with mine and I just hand tighten it. I’d recommend some low strength loctite to start with and see if that remedies the issue for you. Another option would be to put the nut in a vise and VERY SLIGHTLY squeeze it to make it a little out-of-round.

Yeah, I was thinking about Loctite, but a spring washer seems more betterer.

Thanks for the suggestions.

I love this site!

- Ruscal

TD-514L.

It’s from the ‘80s, picked it up a while ago for $100. Unused. Through dovetails only, but it’s a solid jig. The only issue I’ve noticed so far is that you have to make sure the… not sure what they’re called, the things the router rides around… have to be tightened very securely or they slip, causing the operator to swear.

I have LOTS of tools that have the defect of causing the operator to swear.

My other dovetail jig, a General Dovetailer II, is so much simpler. But this is a 12” x 5” frame that wants big-ass tails, not just a drawer.

Bill, plumber’s tape is a good idea. Will try it.

There are some that cause the operator to invent new swear words.

I had the same problem with the Leigh bushing. I ditch it and with a standard bushing and solved my problem. The fact that the material they used to make it is just not as good as a brass bushing.

My bushing isn’t made by Leigh, but I hadn’t thought about the quality of the bushing itself.

+1 PTFE plumbers tape

Bought a set of cheap shop fox router bushings, and they would not stay tight. PTFE plumbers tape solved the problem.
Bought a inlay router bushing set from infinity, and there as obvious difference in quality of threads. Didn’t need plumber’s tape on that one.

Spring washers (or wave disc springs) can be bought from McMaster Carr, 10 pc for < $15.

Peachtree also sells one for $6.
