JB Weld temporary sight attachment

[Col. Batguano]

Super glue (stated several times above) and soft solder are the more popular ways of doing the temporary hooked breech/ barrel attachments. Both will release with heat.

Myself, if I were building a hooked breech gun I would go with soft solder because it's more permanent and will also give you a better full contact mould for the parts to nest together once the assembly is complete. If you burn away the super glue residue you might have some gaps and a little bit of slop for the barrel to move under recoil and spoil some of your accuracy.

The best answer of course is to ask Dave Person how HE does it. He's built a ton of hooked breech guns.

use solder to join the two parts together for inletting.

If done correctly, JB weld will be a more permanent bond. I would use something else for a temporary bond.

Acraglas is my go to for joining a hooked breech for inletting. It is amazingly strong on clean parts. You do have to heat parts to get them apart and this NEEDS to be done outdoors as fumes are terrible. Residue will clean easily with a wire brush.

Didnt know where to post this, so posting here. I am unfamiliar with JB Weld, but I have heard of folks temporarily attaching a sight using this material. While the job I have is not for sight attachment, my question relates to how strong is the bond, and is it easily detached with heat? Thanks.

I temporarily glued a front sight on a rifle. That was several years ago. It's still there, and looks like it's not going anywhere

Regular epoxy works too. Comes apart with a little heat and cleans up with a little filing and sanding.

I would just use a low temp plumbing solder, hit it with a torch for a few seconds and it will fall off.

burning off JB weld might not be the healthiest thing in the world, i woudlnt make a practice of it.

Have used it on a Browning Hi-Power front site. Works great.

Thanks. This has to do with inletting a hook breech and barrel. In order to inlet properly, I was thinking of JB Welding the hook breech to the barrel and then inletting the unit as a hole. This will help in aligning lock and barrel, and inletting barrel breech area.

Frod- I think we all got off on the wrong track. Folks build guns all the time, inlet barrels, etc. I don't comprehend what it is you are trying to do or why you feel you have to temporarily attach the hook breech? Is it a straight barrel or a swamped barrel? What are your concerns?

Super glue can be removed with finger nail polish remover. Anything with Nitro Methane in it. A local hobby shop for balsa model airplanes will have designed releasing agents for sale.

Super glue releases fumes which some people are allergic to. It is also something you can acquire with prolonged and repeated use. So just because it doesn't seem to bother you now....................

JB Weld can be made temporary simply by NOT cleaning the parts prior to joining. Though this could make it more temporary than you want.

Thanks for all the responses. Never thought of AcraGlass, might try it, if the current attempt with super glue does not work. If AcraGlass doesnt work, will try soldering, then Acraglass. Sorry for any confusion here. The plan was to fasten the tang and breech together on the barrel to create a unified assembly for fitting the assembly to the stock and lock. Did not want to inlet the tang and barrel separately.

Acraglas is tough stuff that seems to get harder with age. Just stripped a custom hawken which had an decades old acraglas stock finish -- never again.

I've only done a couple of rifles from a blank of wood. The hooked breech usually is such that the end of the barrel fits tight against the tang. I've done it "Backwards", the barrels I got had the hooked breech installed so I turned the barrel around and had the muzzle tight against the tang. It worked okay.

Use epoxy to hold them together. Easier to remove when done.

Might try E 6000 but wear rubber gloves. There is a product sold by Brownells with the word Black in it. Is a super strong and expensive epoxy that I may try instead of JB Weld for a glue on rear sight for a Tulle on the round part of half octagon-half round barrel. Probably too strong and permanent for your hooked breech project.

I JB Welded 2 scope bases on my 50 cal and it's still holding after 100 shots. I shoot maxis and I'm not shy on powder.

 

[Col. Batguano]

The barrel (with the plug) is inletted first, and then the hooked breech is attached so they all are again inletted as a single unit. If you try to do the hooked breech all by itself it's almost impossible to get a nice tight fit and lock up when you take the barrel on and off.

I've used JB weld to raise the height of a front sight on a CVA Hawken rifle, This was meant to be a temporary fix. Just to get the proper new sight bought. But as sometimes things happen , sight was never
bought and am still shooting this rifle to this day , no problems after 10 yrs or so. I guess I should replace
it.

FWIW, the super glue seems to be working well. Working on filing the tang to conform to the barrel in order to inlet properly. The Baker is a bit of a challenge, but making progress.

J-B Weld can withstand a constant temperature of 500 °F (260 °C), and the maximum temperature threshold is approximately 600 °F (316 °C) for 10 minutes.

It ain't coming loose! I have fixed engine blocks and heads. No failures
