Correcting primary extraction

[Rustystud]

Alex, As you said there are many ways to skin a cat. I differ with you that it can be done in 15 minutes. It took me longer than that to watch your video. I have not seen a current production Remington 700 with the correct timing for it to have any primary extraction. In most cases the bolt handles need to be moved both forward and counter clockwise. To do the job correctly the finger strap most likely will have to be shortened about .040". The quality of the new short cam bolt handles don't make them good choices for re-welding either. The currently available replacement one piece bolts have the same timing issues as the factory bolts. The currently available replacement two piece bolts require some machining to make them time correctly. I don't have a laser welder and can not justify the expense. Therefore I choose the second best method to attach the bolt handles with a TIG, pulse argon purge fusion weld. I do use a little filler (ER70, 4140, 416, 410, or 309) under the bolt handles, depending bolts original bolt/handle content and if it is going to be blued.

Silver solder melts at +/- 1200 degrees. Steel/Stainless steel starts loosing its heat treated properties every time it goes over 800 degrees. A once strong steel handle becomes a brittle piece of junk if heated too much. With Laser and TIG one can control the heat much better.

To each his own, mouse trap.

You refer to using heat to remove handle as a rookie mistake. Just, curious...how do you remove a handle in order to reuse it? If the handle is heated just enough to soften the silver solder, will that affect the bolt in any way?

Your answer is in the sentence/statement.
Induce harmonics into the handle to remove it-adding heat is a rookie mistake!

Nat,
-You Tube producers know all!

Gents-
To clarify any misleading information from a video.
Any "D,E,F,G,RR" prefix serial numbered receivers OEM Rem production bolt handle is of "short cam" configuration as I've coined them 20+ years ago.
Remove the firing pin assy from the bolt body.
Insert bolt into a cleared action & cam into battery.
Lift handle until handles extraction cam surface contacts the receiver extraction cam surface.
Handles extraction cam surface is a steeper angle,not drafted & does not match the receivers 35 degree drafted extraction cam surface.

Re-positioning is not the misleading answer.

Nat, the video is only 6:18 long, were you pausing it? I've watched Alex do many bolts and he's fast, so fast it makes no sense for me to do my own. All his tools are right at hand, the jig he made lets him just set up and go no screwing around, never sat there with a timer but I know I've drove over to his house, he's set up and move a handle and I'm back in my shop in half hour so 15 minutes ish would be about right.

I have a hard time understanding how this all got turned into some voodo chicken bones kind of job, every gunsmith learned bolt handle work on a Remington like day two, it's not the kind of thing you need to know prefix number or blueprints you just need to run the action and observe some very basic geometry.
I really don't understand a guy puts up a video with exactly what he does, no smoke and mirrors, no acting like a mere mortal can not understand the work and it's somehow a bad thing, video is wonderful way to communicate the only bad thing about it is you have to be honest and people actually see the real deal so I guess if smoke and mirrors supports your business then maybe a video would be threatening! There are many videos of guys handling this in different manners, kinda like how many methods guys use to dial a barrel, I find them all helpful.
A guy can make this job as hard as he wants, many guys over the history of Remingtons use this basic method, simple fast and gets the job done, I know guys who pop the handle tig the geometry then recut it and tig the handle back on, or just pop one handle and put another one on like a Holland or other, I'm really looking forward to Nat's bolts, that many be the end of moving handles for me.

Alex, as soon as I seen your video I knew there would be some fall out. I know what works you know what works, so keep making your videos. Thank You!

If I wanted a new bolt handle put on my Bat, I would have it tig welded. But on my less expensive Remington, your way works just fine.

The magical engineers just keep beating this poor horse. Seems that there is just no end in sight.

Just trying to understand...how do you induce harmonics into metal. Isn't it a characteristic?

A big hammer.

And yet another DIY tig- jig that's worked for me over the years....
That big chuck of Aluminum makes for a heck of a heat sink....

Preacher,

Now that's one hell of a heat sink. Lol.
