Welding a springer's barrel block?

I got an idea... Oh god...

So those of us who have used a shotgun style sling on a break barrel know that the sling loves to slide around if it doesn't fit JUST perfectly.

I have some old belts laying around that are nylon/canvas. One of which is a cheap camo pattern. The other is almost a perfect match for the blonde stock on the D34.

I figured that an easy- and cheap- way to permanently mount a sling would be to take a chain link or such and simply weld it onto the barrel block. Then the sling could be taken on and off some other means, but the mount is there. It's also secure.

The real question is: how much will the heat from the weld affect the metal on the block? I have read that as long as the last 6" or so of the barrel is straight, the shot will go straight. I intend to TIG it, so I can get perfect control of the heat, but I still can't keep it from disappating into the rest of the block, and eventually the barrel.

On a side note: I would need to remove the bluing from the block before the weld... any ideas on how to carefully remove just what I need to?

While you may only really need 6" of straight barrel at the muzzle end for accuracy, you have to keep it aligned properly with the sighting device, whether it be open sights (could be a problem if anything warps) or a scope of some sort.

Remove the bluing using lacquer thinner or buffing it off.

I'm not committing one way or another that this is a good plan, but I wouldn't mind seeing the end result...

I'm thinking that it would be best on the end of the block, right under the barrel. Since I'm not commited to left or right handed shooting. Going from either side would probably be best, but then I'm forced to sling my rifle on that side.

Tig weld would be the best strength & aperance...
The trick is to internaly purge the barrel as you weld
By having Argon gas flowing though it as you weld..
The Argon will desplace the air and stop the internal surface
of the bore oxadiseing ..heat & O2 reaction...
But if you are welding on the breach block the join where the
barrel is pressed or threaded in will act as a heat barrier &
reduce the amount of heat that reaches the barrel..
BUT DO THE INTERANL PERGE.....

Pete

Ps..The breach block is thick enough to drill and tap a thread
with out going into the bore....

Hmm... If I were to put a hole in the block it would be infront under the barrel so I can have an ambidextrous sling. It would be quite tricky to drill/tap a hole in that position.

Tricky just takes a wee bit longer....

why dont yer bend a U up with a ID the same size as the breach blocks
OD then use the hole that the cocking arm/breach block pivot pin goes though..replace the pin with a bolt "4/5mm" that would go though the
sling loop / breach block / cocking arm.....

I've seen this, and where the barrel enters the breech will be fine. I have seen them an inch or two from the breech. Those were big rifles with big barrels though.

Should have mentioned I would likely do it on a Diana 34, 350, or Super Streak.

Kanyon, how should I fill the barrel with an inert gas? Will a 3:1 CO2:Ar mix work? I only have ready access to that, and Helium.

Any gas that dose not contain O2 or will go BANG will work..
just put a tee in the gas line to the welder ..with a small tap to adjust the flow "dosn't need to be much"...And stick a peice of plastic tube in the end of the barrel and have the gas flowing though as yer weld...

3:1 CO2 / Argon mix .."argon sheild"
will work...mainly used for mig process on steel
but has a very low O2 content.....

BUT.....if you are going to tig weld it you must have argon gas.. Question

In shop we either use helium or the CO2/Ar mix. I've gotten clean TIG welds using the CO2/Ar mix on aluminum, stainless, and 12g sheet. I've done aluminum MIG with the same mix (god the splatter left me two nice scars on my knee, just 10 minutes of welding too.), and it works perfect for regular steel MIG.

Birchwood Casey Blueing and Rust Remover with steel wool works reasonably quickly.

This is a sling swivel stud that I made for my Slavia from a carriage bolt. I used the four-sided bottom part of the head as a guide to cut the upper part (with a Dremel and abrasive cutoff wheel). I cleaned up the cut and adjusted the width to fit inside the sling swivel (using a file). Finally, I drilled a hole to accept the sling swivel's pin. There's a lot of "meat" in a carriage bolt head, and it is inexpensive. This kind of stud could be welded or threaded anywhere you want, allowing the use of commercial quick detach sling swivels:



I find kanyon's "U"-shaped fixture most appealing.

Fritz if you don't want to weld a sling connector on to the rifle, then why not make a bolt on connector and fasten it to the cocking link.
