Removing Chicago Screws

[fredk]

Loctite what? Loctite is the brand name. They make thread lock, various adhesives including superglues

Loctite thread locker, I'm sure. I've done mine with the blue, because I know how hard the red is to remove. I tried to remove a couple on a neighbor's belt that I made. Couldn't do it without doing damage. I smell a fish here with the customer. I've been using Loctite thread locker in gunsmithing for quite a while, and a couple of decades with dental equipment before that, never had a failure, unless the threads were coated with grease or something before application.

I've since decided to just figure the CS is a sacrificial element if I want to remove it, and use a Dremel to cut a slot in the smooth half, and replace the CS with a new one. I've got bags of them, don't know why I tried to save the one. Just got silly, I guess.

I do not know, but does Loctite work well on brass? Just a thought. I use the blue wood to leather with nickel plated Chicago screws all the and never had a problem. Any answers will be appreciated. As I have never used brass screws before.  

Oh yeah.  That's why I'm so puzzled.  The only thing I can figure out is that I am putting a hell.of a lot of torque on them screwing them in so maybe when they stripped out.

All of my Chicago screws have fairly coarse threads, so the Loctite thread lock is pretty much necessary. I likely use TOO much thread lock. I've always been one of the "if a little is good, a lot is better" people. THAT has bitten me in the arse on more than one occasion.

The Weaver tool is also handy if you have to drill out a rivet.

Not shrinkage.  He said they are coming out.  He resells them, so...

Well, that sinks that theory

The Weaver Leather catalog shows the same tool for $16.95.

Thank you as well @Sonydaze

They look like they could be quite useful at times though perhaps a bit slow and cumbersome to use.

I just use a crepe rubber sheet and lay the belts over and press down into when I do them up. Indeed as @fredk pointed out they do loosen up due to shrinkage so I re-tighten them again at least a day later and normally get another 1/2 turn tighter. Yeah and I don't use any locktite-glue or whatever.  Made thousands of belts over the years and only had 3 maybe 4 say they came loose. They were many years after the sales and I always been happy to replace for free. Fishy customers soon learn they gotta pay more as well.

I am an airplane mechanic, I use loc-tite all the time. All of our loc-tite has an expiration date after which we throw it out because it loses its ability to hold. I don't think the civilian bottles have expiration dates, but they should.

Was your loc-tite a fresh bottle?

@RockyAussie Man those are some beautiful belts.

In general, blue is for threads you want to be able to get apart and red is for those you don't. In either case, the tiniest drop is usually enough.

If you do use red, don't use the hi-temp stuff. It's made for, well, hi-temp applications like engines, etc. and is almost impossible to unscrew. The regular red stuff will generally release with heat.
