Bingo!
Thank you Sir

Remington stock bolt handles have a pretty small primary extraction ramp. I've found it much better in every way to just replace the handle with a PTG handle and knob.

It's easy to make one though if you feel the need:

Oh sorry, maybe I wasnt very clear
For "threading" the Bolt handle for a tactical knob
This is the only device I've seen so far.
I was going to take some 2" Alum round stock and drill a hole at the angle needed to secure the Bolt Body
then split it in half to clamp the bolt into. Then thread bolt handle
I just like seeing other ideas if there is a different way to do this.
Holding the bolt body in the 4 Jaw is fine as I've done it that way a few times, but somewhat risky if the bolt turns at all.
So far it hasn't happened to me yet, but those were my own bolts so I decided to just go for it.

No the device you have shown is a LaBounty Bolt jig which I also own 2 of those, And they are for opening bolt faces and truing lugs, But they really aren't the best for doing that job. I also own a Phase II bolt threading jig like the one Dave Tooley just posted. They work very well, I am not home, But a while back I posted a pic of my old Shenwai 12x36 with my phase II bolt jig and a 300 Ultra mag bolt in it that barely clears the ways, I'll try to find it.

Good info on the bolt handle, thank you
And your Jig there is pretty much what I envisioned as I have a good length of 2 inch stock and wanted to use it for this.
(It's on the "when I get some extra time" list, not on the "Need to do list"
planning ahead for the time being

That fixture allows you to dial it radially but axially.

I agree the LaBounty fixture leaves a lot to be desired. Good for radial work but not good axially. Other ways to skin that cat.
One eye opening way is use a rotating 3 jaw chuck in the tailstock holding the nose. BTW handy piece of equipment to have. Use a trued, threaded mandrel in the other end, held in a 4 jaw. Then run an indicator back and forth, adjusting the 4 jaw to get the bolt sides running axially true. That will keep some of you up at night.

Funny you brought that up, I was just eyeing those yesterday price shopping them.
That is a definite on the "Next to get" list

Doesn't have to be pretty to be effective...

What I first thought and was hoping is
An easy way of holding a bolt to thread the bolt handle
See if you can see what he comes up with there that is easy and not expensive

He said for the Howa it was easy as the bottom of the bolt handle is flat and has a hole/recess in it, so he just set it up in the mill leveled the flat bottom of the bolt handle and drilled and tapped it for a threaded insert then made an aluminum knob extension and bolted it on via the threaded insert.

Cool thank you,
I've watched a vid of Larry Potterfield (Midway USA) doing something similar to extend Rem 700 bolt handles instead of threading the bolt knobs.

I'm not a machinist by any means, but couldn't you clamp the bolt body in the tool post, set the compound to the correct angle and put a cutter in the chuck? Kinda like a horizontal mill?

Nice!!!!
Another interesting idea
Yes a guy could make that work, possibly by turning the O.D. with a Rotabroach
then just use a die to thread it

Annular cutter is what I was thinking. Then just a die in the chuck.

LA Bounty jig.
I have one of those, but thus far, other 'shiny objects' have kept me from trying it.

I will say the last one I did, I ground the bolt knob down on a 2x72 belt grinder roughly round enough to thread with a die and epoxied the knob on, lol. Its still on there and working fine after many years.

That would be the wrong jig my friend
That's for facing and doing bolt lugs
Wouldnt allow for threading bolt Knob
----------------------------------------------
The one Mr. Tooley Posted would be the one
since the whole body has to be held at an angle, as opposed to being inline and parallel to the spindle

I was referring to the image in post #20.
Apologies. I failed to realize the thread had moved along.

Copy, now I understand what you're saying
At the time, the pic I posted was the only fixture I had found and knew it was not the one I needed
which is why I was asking

Like most things. Yeah, it's been done before. I knew I had seen it at one point and went and found it. Instead of the boring bar you could do the annular cutter in the chuck.
