JB Weld temporary sight attachment

[Frod733]

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.

If you apply it to clean roughed up metal, you will most likely have to file or grind it off. Heat will work, but you still have to deal with the residue. I've used it to seal a weep hole on my 1949 Willy's engine block, and used it to repair a cracked crank case on a lawn mower engine. Paul Harvey always advertised that you can fix anything with JB Weld or Duct Tape.

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.

I would think removal would be a big problem. Also, I think the shock from repeated shooting might be a problem causing a sight to fall off but the weld to remain.

I used it for a sight- no problem- it will stay on.

Stuff is very hard to remove. Seen damage from frustrated removal attempts without some heat.

I repaired a cracked engine block on a Briggs & Stratton 8 hp with it. That was in 1998 on my snow blower engine. It is still holding.

I glued a silver sight blade onto a 5 1/2 " Pietta 1860 Army revolver. That was about ten years ago. Still holding. Only thing I have to do is polish the sight once in a while.

Few things are as permanent as a temporary fix.

Thanks for the responses. I am not attaching a sight. I am wanting to "temporarily attach a hook breech to a barrel to create an assembly that I can use to inlet barrel assembly. The concern I have is whether once I am done, I can remove the attachment with some heat. The JB Weld says it is good to somewhere within 250 degrees or so.

Relatedly, is there some other kind of adhesive that will hold as well and not be problematic?

 

[Frod733]

The JB Weld will not be permanent, only temporary until inletting is done.

No matter what type glue you use to glue the tang to the breech, your still going to have a problem with the barrel not seating tight against the tang once you inlet and remove the glue.

I made a carborator float bowl for a cj5 Jeep 4 banger years back and it worked for several years til I sold the Jeep. Don't know how it's doing now.

Try super glue. It will bond in a hurry and comes apart easy with some heat. Try it on some scrap steel pieces to get a feel for it.

Thanks for the responses. BTW, found this link while looking at different types of adhesives. Kind of interesting

The front sight of my Pietta 1858 Army revolver came off. I used the JB Weld to reattach it and it's held for over 3 years now. JB weld is a great product. But it is not for any temporary use.

Orbital sanders, JB Weld and Dremel...three "tools" that make gunsmiths cringe. With that said, JB weld has some specific uses as well as Dremel tools.

This, however, is not one of them.

 

[Frod733]

This is not a permanent attachment. I just want to temporarily attache, and hopefully easily remove once done.

I have a rear peep sight epoxied down for testing, hoping it lasts long enough for me to decide if it works so I can drill and tap holes. That said, it really needs to be farther back so I'll probably end up getting a tang sight.

I use medium viscosity CA (super glue) for that job. Activator for the CA will make it a harden instantly. It comes off with heat. It will make noxious fumes when heated.
