I wish I’d added those skills to my life - fascinates me to this day. Nice work - keep us posted on your progress Last edited by PintsofCraft; 02/03/22.

Spinning the assembly to distribute epoxy was a good idea. I think the flutes are good next step. Don't speculate when you don't know, and don't second guess when you do.

Maybe flute the Aluminium to increase surface area even more? The Aluminium at least transfers heat, while CF is a poor conductor. I remember seeing barrels for Ruger 10/22’s and a couple of 22 pistols that were aluminum sleeves over steel, even fluted. I don’t remember who made them though. Last edited by drano 25; 02/03/22.

I really wanted to see if I could really do something different. The aluminum acts like a big heat sink, and should really aid in barrel cool off. Also, I wanted a large diameter barrel, without the weight. I got that too. No flies on a factory Tikka, as I own a few of them. But now, I have a large diameter switch barrel, that doesn't weigh a ton. Not to mention, it's pretty cool!

That is one problem with carbon, I've read conflicting reports on whether it traps heat or aids in cooling. The only thing that would worry me is the JB weld. Epoxy gets soft when heated. Not sure what other options there are though.

That is one problem with carbon, I've read conflicting reports on whether it traps heat or aids in cooling. The only thing that would worry me is the JB weld. Epoxy gets soft when heated. Not sure what other options there are though. Bingo. Carbon fiber does not conduct heat very well. They use either atomized aluminum, or tungsten to their epoxy to help with cooling. But if they added too much, you wouldn't be able to see the fibers. As for JB, it's good to 500 degrees. I don't think I'll ever get it that hot. But, as a fail safe, the muzzle is threaded. If the epoxy were to ever fail, the sleeve would not be allowed to move due to being held together by a tightened nut, ie, brake, cap, or suppressor.

Why, just yesterday I bolted an MDT chassis to a T3 223 barreled action. _________________________________________________________________________ “Montana seems to me to be what a small boy would think Texas is like from hearing Texans.” John Steinbeck ΜΟΛΩΝ ΛΑΒΕ

Also, there can be an issue getting the pieces together before the adhesive sets up. I have sleeved barrels using both acra glass and loc-tite and the epoxy is much more forgiving and gives you time to work. GD

Small cuts, with the correct speeds and feeds. Plenty of coolant, and control any chatter. I thought about having these cryod, but I really took my time cutting these without producing much heat. Most of my heat left with the chip.
