Need barrel band help

21 July 2016, 17:05

This is my first needing some help. Have liquid rosin flux, fry 99% tin. I cleaned, applied flux, map torched to melt tin but then use steel wool to tin the ban. The process goes south at that point. What am I missing. thanks elton

When tinning, I use a clean cotton rag to wipe with.

Here's a hint, try blackmax.

I think im getting too hot. Brownells sales a blackmax lock tie is that the product jim mentioned?

The steel wool also has oil in it that can contaminate the solder. Wash it and dry it with Acetone or other hot degreaser prior to using. Just a thought..Bill

Yes, the Blackmax is Locktite super glue.
I don't wash the steel wool; most likely the OP is getting it too hot.

I have seen an instance wherein Black max glue from Lock tight melted when a clients gun was left on the hood of the backie in some horrific heat, my guess is 110 degrees, maybe more, while we packed out an Eland..the swivel and barrel band front sight could be turned over by hand.

If I were to use it I would brace it with a set screw, but I think I'll use solder on my guns..Some guns get used real hard, others get by from being pampered for lack of a better word, is my guess..

Well, I guess I do it wrong but.....I don't tin it.
I clean both surfaces of course and apply flux, then position the band. Simple propane torch and apply heat. When the band/barrel gets got enough to melt the solder, I start applying the solder like I would on a copper water fitting. I keep adding it as long as it will suck it in the joint. Seems to work fine, never had a problem and you eliminate a step that can "go South" as you say.
Probably the simplest way.

Loctite claims it's good from -65 to +225 F. Must've been really hot that day...

And I think Ray must have had a brain fart that day; I have tried to remove a part that was done with it and had the part red hot and ruined and it would still not come loose, had to cut it off.
