700 Bolt Handle Welding

[LynnJr]

I know Dan Armstrong in Fairbanks Alaska can tig weld 4 handles on for $270 shipped and insured.

Can anyone in California match that deal?

[kcstott]

are you talking just tig welding an existing handle that is currently on the bolt to over come the issue of the solder? or are you talking about replacement handles on bolts??

[LynnJr]

I have 4 new PT&G bolt bodies and need the PT&G handles silver soldered or welded on.
Just looking for someone a bit closer to northern california that can do the job.

Not for 70 ish dollars each.

If they’re not going into actions that have been trued with the bolt that should be done first to avoid timing or clearance issues.

..and if going with PGT bolts, why not one piece?

[LynnJr]

One piece bolts are the latest fad that don't allow you to time the bolt or allow you to reposition the handle after the lugs and abutments get cleaned up.
And yes the receivers are already fitted to each bolt body.

Must go to ffl if receivers go with them. If just bolts ask Randall ar15 down here.

And you're not going to do that once the handles are tig welded to the body's. which is the reason i said the actions have to go with the bolts, and be individually fitted and numbered to each action. There is no other way around it.

Here is the fixture I made to hold bolt handles in alignment on the bolt body so I can check timing and alignment in the receiver before welding them:

I believe that PTG significantly tightened up the bolt handle location on the one piece bolts so that they will work with trued receivers because a PTG one piece bolt will just barely fit into a non-trued receiver compared to how sloppy a factory bolt is in an un-trued receiver.
I have not taken measurements and logged them to show the data, but the difference is quite noticeable on my workbench.

It usually only takes a few thousandths to clean up the lug abutments while truing and the PTG one piece bolts have MUCH more primary extraction cam engagement than an un-trued receiver with a factory bolt.

you're lucky if you get any primary cam extraction on a factory action.
They usually have about 1/16" gap. this is on recently made actions too. Maybe back when they had a custom shop and you had to order a 40X things were better. but not in the last 25 years or so.

Dan has a pretty fast turn around when I sent my bolt to him. I think it was in and out of his shop in a day. Total time was just over a week.

I'm not sure what he does with a new bolt, but with existing bolts he has a few measurements you need to provide for him to use for timing.
