Can anyone recommend what type of Locktite to use for a .22 rimfire barrel liner? In the past I have used Acraglass. Locktite sounds easier to use: no mixing.

All suggestions will be most appreciated. Thanks! Joe

Locktite will respond directly to your question - an engineer will give you LOCTITE's recommendation.  Hmmmm.  They are in the business - ask them!

JB Weld is about as good as anything and better than most for barrel liners. It is good for 600*F and chemical resistant. I haven't exposed it to hot bluing, but see no reason it would cause a problem. It is cheaper and easier to get than either LocTite or Acraglass.

The red Loctite threadlocker, I forget the numbers, since there are many, takes heat in the area of 900 degrees to release.
Some of the other will take up to 1200 and up to release.
On the Loctite web site it will give all the information needed for use, and the swell rate and the amount of heat each will tolerate.

Most folks will be amazed the strength these adhesives will provide.
Most will easily hold any liner in any re-line job.

No reason to even think of soldering any more, I helped do it once, and that was way to many times.

I have been using Loctite 262 on liners for many years. I notice now they have a whole lot of different types that may be better. I have never had a liner come loose and even tried to remove some when I made a mistake, had to drill them out, heat had no effect. The 262 will hold up in hot tank blue. I think the fit is very important and try for .002" clearance using reamers to get as close as possible. I have one lathe dedicated to reaming barrels and make most of my own reamers. The reamers have cutting oil pumped through them to flush the chips out, same setup I use for rebores. The liners I use come from T.J.'s which I believe has the largest selection and the best hammer forged liner.
When installing coat the inside of the barrel and the outside of the liner. I end up wasting more than is needed. I clean both parts with break clean before applying the loctite. I bevel the end of the liner to help spread the loctite in the barrel. Next, run a patch through the liner. You don't want any loctite in the bore, once it is hard it don't like to come out. Any heat will start the set quicker, cutting the ends off with a hacksaw is enough heat to start locking them in place, probably do to the close fit. If you want to know how to hide the liner at the muzzle you will need to e-mail me and ask.

Thanks for all the ideas gentlemen. Locktite it shall be!

I must say that I use JB weld a lot in my shop. Nothing cheap about it at all, and a fine quality product indeed. The JB Quick style is especially nice for making barrel bushings, as it sets up fast. I have all kinds of epoxy's, and JB gets the nod for many jobs. 

Safe and happy shooting! Joe
