Anyone on the front range (I'm in the springs) set up to silver solder muzzle devices?
Trying to avoid $60+ each on pin and welds
I could provide the silver solder if necessary

No. You need silver solder. No the solder from home depot.

You can physically do it with Mapp but you want acetylene to do it quickly. Or oxygen and acetylene to do it right.

Getting in and out with the heat fast is the key.

Alternatively weld the thing on there.

So I could use that torch and silver solder (I see some on eBay)?

Silver soldering requires a deft touch, and someone that knows what they're doing.

I've got more of a 'fuck it, we'll do it live' mentality but it's good to know when I'm in over my head.

This is one of those "six months ago I cudnt spell weldor, now I are one" things.  It's easy to screw things up if you don't know what you're doing.  What flux?  What solder?  What torch, and at what settings?  You might watch a bunch of the vids here:

https://www.youtube.com/results?search_query=silver+soldering

Can you solder copper pipe?  Any experience at all?  You'll want the solder to pull into the joint via capillary action.  You want to get it hot, but not too hot.  You can affect the temper of the steel.  Is ruining a barrel worth the chance?  I've been welding for over 30 years, I'd be hesitant to do it to one of my firearms.  I suggest you take it to a professional.  Pard, I'm not trying to harsh your mellow, I'm trying to save you some heartache.

Why do you want to silver solder or pin and weld the muzzle devices?  To bring a short barrel up to length?  To meet federal regs, in other words?  If not, you might consider one of Loctite's high temp/high strength threadlockers or retaining compounds.  Are the barrel and muzzle device threaded?  Smooth?  I've used 620 to attach slip fit muzzle brakes/flash hiders to barrels.  That stuff will not let go unless heated to 450 degrees or more.  The parts must be degreased, clean and dry before use.  Follow the directions, of course.

I read of some company that uses Loctite 620 to glue shotgun barrels into their receivers.

It's about as hard to silver solder as is it to learn mig. Probably less. If you can sweat copper it's the same thing with more prep work and higher heat.

The only reason to silver solder or pin/weld muzzle devices is for atf regs.

If rob at bowers is back in action he could knock it out but you'd be paying for his time.

I pin and weld exclusively.
Proper silver soldering requires heat of at least 1100 degrees into the barrel for the solder to flow.
You really want that kind of heat introduced to what many consider the most critical part of the barrel?
Not to mention destroying the finish.

Here's an ignorant question: what do you use as a pin?

3/32" or 1/8" hardened steel dowel pin Brad. ACE Hardware or JAX carries them, probably .20 each
