The basic story is the handle was repositioned in a previous life, and it didn't go well for someone. I was asked to try and "unmurder" it.

Step One: Removing the cancer caused by a wire feed welder:

Next, a quick zap to set the position and check alignment:

With the handle "stuck" now I work on the root and fill passes:

Welding is all done, so now it's time to clean things up:

Almost 20 years ago I borrowed a friend's wire EDM and altered a Hardinge collet by cutting raceways in it like a receiver has. It has proven itself to be a valueable tool. Here I'm using that collet to hold onto the bulk of the bolt body to keep from having a whole bunch of unsupported material hanging off in space. Using the rotatry is perfect for a job like this because it gives me unrestriced access to every side of the part that I need to work on.

With the hard part over, now it's time to blend and polish.

One more kept out of the grave:

The staff I have are all rock stars in my eyes, as they've gotten quite good at what they do here. It's nice because it allows me to take on jobs like this. Something I've always had a soft spot for because repairs like this are typically avoided like the bubonic plague by most shops.

Appreciate the kind words.


Edit:

You remind me of something from a long time ago. A gent had a 40x in his family for several years/decades. An attempt had been made to blueprint it, and it didn't go well. The timing was off when chasing the thread and made a mess of things. Typically, that is a one-way street, and it goes into the garbage can. Rolling the dice, I turned a stick of heat-treated Chromoly to 1-3/16 and threaded it to a 28-pitch.

From there, I set it up and ID bored/threaded the receiver to the same thread size. I warmed it up along the face with an induction coil and used low-temperature solder to "glue" the two pieces together. As an added measure of paranoia, I poked a hole along the seam and stuffed a brass pin so that it'd also have a mechanical lock. -ensuring the plug never backed out of the receiver on a barrel removal. That all went well, and I finished it by restoring the factory 1-1/16_16 threads. I'd be reluctant to do this on a magnum caliber, but the gun was chambered in something relatively small. It worked, and I could see the smile over the phone when I talked to him afterward.

I'll take being lucky over being "good" any day. lol.
