I am planning on bedding my scope base and I have one question. Will flux stop JB Weld from adhering to my receiver? I'm thinking it will work just fine, but I was hoping to get some opinions before I dive into this blindly.

Thanks

Re: JB Weld and Flux

I did mine recently using JB Weld and used the Kiwi neutral shoe polish. It went on easy and worked perfectly. I screwed up the first time I tried and didn't let the JB Weld cure enough. Have patience and wait at least 24 hours. Some people don't wait that long but better safe than sorry. Cleaning it up the first time was a mess.

I think the point that is being made is, since since so many people have successfully used neutral shoe polish, Johnson's paste wax, pure carnuba wax, etc. why experiment with something as esoteric as soldering flux?

Another way to look at this would be to ask yourself what advantage soldering flux provides over already well proven products?

Re: JB Weld and Flux

JB Weld is an epoxy glue. Flux will attack the metal of the receiver and probably remove any finish that exists. Either use a wax, or just glue the base in place. A little heat from a small propane torch will easily separate the epoxy bond...if you ever want to do so. JMHO

Soldering flux is an acid intended to etch the base metals so solder can adhere better.

Doubt I'd want to use it to replace a release agent.

Lemme put this as tactfully as I can.......that's a stupid idea.

Stupid idea huh? I was referred to use it by my friend who is experienced with this stuff. I just got finished using this and it worked great as a release agent. So, I guess its not such a stupid idea. You can add flux to your release agent list now for JB Weld. Also, it didn't react to the receiver, and the finish is still pristine. I was asking about tinning flux because I had some laying around and it is the same consistency as shoe polish, et cetera, and I did not want to buy something I will probably never use again except to stop JB Weld from adhering to metal.

The guy isn't experienced in precision rifles. He said it would work for a release agent, but I wasn't too sure, so I asked the Hide for gunsmithing suggestions. I didn't appreciate "Lemme put this as tactfully as I can.......that's a stupid idea" comment like I'm an incompetent idiot, so I replied with my results to confirm that it wasn't a stupid idea after all.

I'd recommend cleaning the action surface and the jb weld on the base thoroughly, just to be cautious...

Going in blind but now you are saying refered to it by a friend with "experience".

Wanting opinions but getting mad when told something you don't want to hear.

You go girl.....

Glad it worked for you there Tiger, it's the last thing I would consider as a release agent on a firearm tho'.

Lot's of other better options.....

Re: JB Weld and Flux

So you risked damage to your expensive precision rifle by putting acid on it just to save $3 and make a point to someone who decided to be blunt and honest since you kept asking if it was OK when everyone said not to? Just how cheap and stubborn are you? Maybe precision shooting isn't for you then. It's expensive and you need to be able to listen to criticism from others in order to learn.

Great point! Precision was the key word and doing things half ass at risk of damage is the first sign to stay away from it much less shooting in general.
