Remington bolt timing

[Bully]

So will that jig.

The other thing to remember, you can have a cold braze just like welding. Heat isn't your enemy. Also using properly made handles will aid, PTG handles are pure garbage. I was referred to Andrew Delikat @ AD ARMS for properly made handles from certified 4140CM. They hold better than anything I've used or seen. The other things on his handles is the extraction cam mates perfectly with the Remington cams.

Andy makes a solid product (builds a hella rifle as well) and is great to deal with.

@carlsbad Who makes that jig or did you fire one up for yourself?

I made it myself. and like most of the tools I make, if I tried to sell them and priced them to pay myself at a reasonable hourly rate, nobody could afford to buy them. --Jerry

Dan Armstrong IS the Man for the job. First class service every time. If it was me, I'd be sending him the bolt/action assemble and let him do his magic.
He knows what he's doing. (www.accu-tig.com)

Can Dan time your 700 bolt close on one of his actions, without sending in complete action?

I don’t know exactly what bolt close characteristic you’re referring to, but Dan did time extraction (by knocking loose and reattaching) my bolt handle without sending in the action.

Yes, getting proper extraction. Good to know, and looks like he does a lot of bolt handle and knobs options too. Thanks for the information!

Dan proved his worth to me!

Bumping an old thread. Suffering this same issue on an RR receiver. Is Dan still the go to person for this work? Or are there other options today?

I had Dan change a bolt handle for me about a year ago. Quick turnaround & nice work.

Remington could have used about 100 of them.

Good to hear. Sent an email but nothing back yet.

It’s best to call him.

Another option:

Services - Primary Extraction Timing & Tig Welding

Primary extraction is expressed as a rotational motion converted to a linear one through the use of a ramp or cam type feature found on the bolt handle and the receiver. Its sole purpose is to allow the shooter a convenient means of getting the fired cartridge out of the grasp of the chamber for...

Have LRI do the tig and timming and put on a 40x bolt handle. IIRC, those have a longer camming surface? I visited LRI’s shop last year and Chad explained it to me then, but I have a shitty memory. Maybe call or email them.

Thanks Gents, good info. I'll start with a call to Dan with a LRI as a backup.

One thing I haven't seen or heard mentioned so far is the fact that with nothing in the chamber the bolt can move front to back some. You don't want that when locating the handle for timing so I suggest you place a case that was fired in the rifle {and not resized obviously} so it holds the locking lugs back against the receiver and then locate your bolt handle for weld/braze/solder.
Don't get me wrong, what little front to back you may have wont kill the thing and render it unworkable...but, if you are going this far to "time" the bolt you might as well have it as "timed" as good as it can be.
I wouldn't worry about it too much anyway...who is that guy that is god's gift to the TIG welding world???...and Christ knows, the absolute only person on god's green earth that actually knows how to TIG weld. What ever you do, DO NOT mention that you are going to TIG weld it yourself...he will blow a gasket and set us all straight!!!!

If you use feeler gauges to check the gap, a snug fitting gauge will force the bolt back so that the lugs contact their abutments.

 

[Walt Krafft]

Moving the handle forward to minimize that gap is one step toward improving the extraction. It does not cure any rotational problems in either the handle or the receiver. That takes rotating the handle or building up the handles cam surface and then machining the new cam surface and/or the handles tail to time the lugs. There are lots of surfaces that interact.

So is proper timing possible by simply having a perfect CNC-cut bolt, or are the minor tolerances of the action such that even that, alone, won't cure every instance.? I suppose if that were possible there'd be a couple of wonderful bolts/heads on the market that fixed this issue.

 

[Alex Wheeler]

I no longer mess with Remingtons but on the newer actions you need to move the handle forward and rotate it counter clockwise on the bolt some. That requires trimming the root of the handle to allow the that. But you dont want to rotate it so much that the cocking piece can hit the bolt opposite of the cocking cam when firing. You can make the factory handles work, but its probably best to get a better designed handle if its an option.

It is a system, quite a complex one, where a bunch of surfaces of the bolt and receiver interact. You can't fix one and ignore the other.

 

[luckyshot52]

Of course it’s possible. Many replacement bolts have been made. Don’t even need a CNC to do it. Would still have to install a handle, unless you were manufacturing enough to justify machining from one piece. Look at how many Remington clone actions are on the market. Most are timed correctly.
