Fluting is so passe.

You want to go with dimpling instead...

[264charlie]

Nice... Think I know a guy that can do that.

can fluting and/or dimpling change how the barrel will act when it heats up?

I think the helical fluting looks pretty neat.

I don't think you do.
I did ONE barrel.
It was the first and last one I will ever do.

Just curious do you use a cnc with a 4th axis or a Bridgeport style with a jig or turntable?

We talk you into all kinds of stuff... How long did that take?

Didn't KAC patent the process?

I've thought about doing one just for the heck of it.

Looks liek about 200 dimples. Probably took about 1.5 - 2.0 hrs with setup.

Vertical mill with the barrel in a indexing head.

I wish I had CNC machines...
That was all done by hand.
The barrel has a straight shank so I just did it in the kurt vise.

Yes.

I recall it being 180 dimples and about 1 minute a piece.

I am working on tooling and a fixture for barrel fluting in the future.
I have all sorts of ideas for a way to make a sorta universal fixture that allows for angle adjustment and goes into a horizontal mill.
