Other The IZH46M Achilles Heel

We all know about the cheap pot metal cocking shoe AA uses with the TX200 and ProSport.
We also know about the cheap screws used in the IZH46M grips.
What we did not know was the other cheap, pot metal parts used in the 46M.
Part #51.
The cocking linkage that retracts and compresses the piston into the chamber.
Last night at the Diablo Indoor 10M match in Bay Point, CA, I was starting my pre-match practice and, after firing three pellets, I noticed the cocking handle hanging freely from the pistol.
I tried to close it but couldn’t because the linkage was broken and was jammed into the slot where it normally resides.
I do not know if pot metal can be welded or not. (I will check with the Motörhead.)
A fellow shooter who is knowledgeable about metallurgy said it was poorly made at the factory.
I am sure I cannot get a replacement part.
If it cannot be fixed, I will be selling the grips, trigger, and several o-ring/gasket kits…

Well, I tried pm but would not go through ...

I was endowed with some IZH 46 parts a while back and mine is gone now... I finally looked through them today but since you didn't post a pic of the offending part, I'm not sure if it is in this cache... If you post a pic, I can check again.

You're welcome to any of these parts if they would help..

Per my friend the high-end gunmaker, he would make a new link from 1040 pre-hardened flat stock, which is available ground to precise thickness (gage stock). He also believes welding to be possible, but would require heat treating to obtain full strength, plus straightening and grinding and just not worth the trouble. The only problem I see is establishing the correct hole to hole distance, although there may be some leeway if there is adjustment for the amount of overtoggle.

I would add that since the break occurred where stress would be expected to be highest, additional material, height or width, should be added to the curved portion if possible. The outside (convex) surface of the curve should also be polished to remove surface flaws (stress risers) that could increase the risk of fatigue failure.
