Re: First time cutting flutes in a barrel

First it stiffens the barrel. Isn't that just semantics? Without trying to be personal, the first statement is incorrect and I do not consider that to be semantics (word play), it's engineering or physics. Fluting is weight reduction (as you stated) and less loss of stiffness than turning the barre...

Re: First time cutting flutes in a barrel

I am assuming you will be cutting on the side with that cutter. You should clamp the barrel to a couple of angle plates in the middle so the barrel does not deflect away from the cutter. Clamp on each side of the angle plates (two clamps each) so you can remove one clamp as you mill across the area,...

Yes, there still are bowling alleys but I have never noticed anyone using rosin.

Re: delrin for bushings in barrel vise

Might work if you wrap the barrel in a sheet of paper.

Re: Close range

There was an police shooting incident a while back in which 140 rounds were expended at an unarmed target and only four hits were made (don't know how serious they were.)

Re: Stevens 20 Ga. repair.

You might consider Parkerizing the piece to camouflage the surface damage. It holds oil well and is an interesting finish. But it's not free.

Re: Gun smithing books

The AGI videos have been on youtube and have been removed. They may have been replaced. There is some confusion regarding this.

My condolences, but 91 years is more than a fair run.

Re: Does lapping in the locking lugs on bolt increase head s

As you have seen, the headspace dimension of the cases is not uniform, so unless you sort cases for a given size, you will never be able to control headspace with the belt (also an example of why you should use gauges to measure instead of cases.) Not so if you headspace on the shoulder, as the case...

Re: Does lapping in the locking lugs on bolt increase head s

Belted case headspace gauges are trivial to make; they are simple cylinders .532-.533" in diameter and .212" to .220" in length. You could make yourself a set in .001" increments if you have a surface grinder. I do not recommend the use of cartridge cases for measuring headspace, even though others ...

Re: cannon

I was replying to the following question:

What is a good way to color stainless, if there is a good way, to brown or yellowish?

I could also say that if you are trying to make the barrel have a bronze color, it could be plated.

Re: Does lapping in the locking lugs on bolt increase head s

Getting back to the headspace discussion, :D , it is always best to entirely strip the bolt of all parts when testing for headspace as the process requires a lot of feel and the mainspring and ejector springs dramatically interfere with the feel to the extent of making the measurements unreliable. Y...
