    Posted: October 21 2018 at 3:01pm
I have come into possession 6 stripped #4 action bodies. All 6 have damaged main screw bosses (king screw). WHY would someone do that? But, my question to the board is how would you go about repairing this problem? All 6 have the threads warped and partially split 1/2 way down the boss. I would really like to repair these and use them for future projects.

I have an idea on the repair. I would need to have one in my possession to see if it is possible. I believe I can repair it...

Simple solution would be to clean the hole out as best you can, then weld the hole completely closed. Recenter with a punch,drill and tap. Closest tap and die to the ba threads will be 6×1.00mm. rethread the screws too. Not to difficult to do...

I see, yes. I have the BA tap actually. I would send it to you, Goosic but there is that ever constant problem of shipping a firearm part between our two countries. Thanks for the tip though, I believe you have the solution and thank you kindly!

Think about it. If you want to try sending one out to me PM me. I have the BA tap and die set and a cute little wire feed welder.

They probably used an adjustable wrench to undo the receiver from the barrel. Why they would screw up the next 5 after shagging the first one is beyond logical thought.Wacko
If they refitted the bolt it may have saved the thread.

Zed. Someone purposely cut into the metal twice and hammered the side of the boss flat so no one else could use the receiver. The two cuts in the photos show that clearly. I've seen this before and I think it absurd people do this.

When I worked, I saw the machinists do similar repairs quite often. Goosic is spot on. They would built up the OD round with weld and fill in the hole. Depending how much extra weld they made on the OD, the would then make it round with a pencil grinder and file. A new undersized hole would be drilled then tapped to accept the threads of the new bolt.

If the receiver is repaired and can be used again for a restoration or customization project,the lotta work becomes justifiable to me. There are six receivers in need of repair. For the very small fee of one of those receivers I will gladly repair the returning five to owner in working condition. Just do not expect an overnight miracle. If a jobs worth doing,it's worth doing right...

I didn't realise those were cut's. Still really stupid though; surely if you wanted to scrap a receiver you'd just squash it in a vice or hit it with a large hammer!
