Need some help, got any welding skills?

[Levi Garrett]

Had a SOB do this to my rifle, (its a 460 Diana)
I requested my rifle back without a tune, he had it for 4 months, I wanted a special air rifle tuned by what I was told was a master, oh ya master ...
A nut job that sent me the gun when I said the cops were gonna visit
Well its busted, pic below, may be able to weld it, looks cast steel, like millet rings.
Anyone figure they can get it up and running please pm $

These guys are the North America distributor, and I they were real good with some warranty work I needed done.

As that piece seems to be one that is subject to a lot of stress (I don't know how that model works) I wouldn't try to weld a new piece on and grind it.

I realize this isn't warranty, but I am sure they will be able to help you out.

If they have any issues shipping out of USA PM me.

If it's cast it can be braze welded, if you have the other piece. But it may break again.
I would try to get a replacement part.
Or, if you can't get a replacement, you could get a machine shop to make you a new piece. Not sure what they would charge you though. It doesn't look that complicated a piece.
Even a good welding shop could fabricate you one. Some round bar, and some flat stock. A little Tig weld here, a little grind there, cut the slot and notch, drill some holes and Bob's your Uncle.

Levi retired welder here. First you need to find out if its cast iron, cast steel or just mild steel. Grind test, red sparks cast iron, yellow sparks -mild steel.You need to make a new piece out of steel or cast steel that starts all the way to in front of the wear/rub mark, because it will not be strong enough, welded at the 2 break points around the pin. Once you have a new piece crafted, take it to a shop that does tig welding. Get them to tig weld it together, hopefully they have oxy-acetylene cast iron welding rod. Is there a local welding college around, some times for bribe(a box of donuts) you can get a little welding done! They usually have cast iron tig rod around(just any cast iron filler rod). I have the rod but not the tig setup. Hope this helps

thats excellent info, I will see what a part is new, and if not that idea of making the part from below the stress area is an excellent Notion
Thanks all

I can tig weld that sucker back together for you. I'd chop off the lug and replace the whole arm. Welding a hole back together can be a pain. You would have to weld and then ream out the hole. You never know how some #### castings will weld till you try them and then see it work. i'd have to see the part to verify what its made off. If its made in China forget it their castings are heinous. What this about the cops being called? hmmm better find someone else.

Made in Germany by Diana Airguns (RWS), Gonna try and take it to a local source, the only thing is getting is the same specs for fit if you remove the effected area..
For those who don't know the gun, its a 22 cal springer, underlever that will push pellets through 1/2 in plywood @ 30 meters. The only time I saw the power of this thing . Then I noticed the slop in the lever, thats odd for a German gun , it sure was eh!

Having that part made will cost a fortune. Buy a new part.

If you are going to get a new piece from manufacturer then there is no harm to trying any one of the welding methods suggested. And if you can't get a new piece then thats what you are doing anyway. Well here is my 2 bits for a welding fix:

Get a piece of aluminum plate, this goes in the slot clamped tight against the broken side. This will keep your weld where you want it. Get your MIG or TIG and build up metal on the broken ends. Do not worry about the hole (I would actually just fill it in) or if you build up too much metal. What you are trying to end up with is enough metal to file away back to original dimensions. As for the hole you can now drill through the unbroken side's hole as a guide.

The aluminum plate should have kept the weld metal from bulging into the slot, you may need to clean it with a file. As for heat treating or cast welding issues I would not worry about it, putting on that much weld on a small end like that will get it nice and hot.
