I recently got a good deal on a barrel that is 20" long, but for whatever reason the last guy attached a brake with red loc-tite. He timed the brake straight and used no crush washer. Pretty ghetto. I want to remove the brake and add something evil. How hard is it going to be to get off? I am wondering if heating with my torch will do the trick or if I'll have to split it with the Dremel.

Heat.

MEK or Tolulene will kill it too. Loctite sells a chemical removal product, as well.

On something the size of a brake, it will probably come off without heat or chems. Do you have an action block or barrel vise?

However, heat or chems will be a good thing.

Yeah, I have all of the above. I tried to clamp the barrel in the vice and remove with a wrench. I need to pull out the acetelyene torch.

Heat with a torch will do just fine. If you go to loctites website, I think they state something like 450F as a temp rating.

I use:
Shrink Tubing heat gun
Oven
Standard Plumbing torch


Oven is good if you can throw the whole thing in.
Heat Gun is the ok and you have less chance to discolor anything
Torch is the fastest and easiest, but you have a higher chance of discoloring the parts. 2-3 second with a MAAP Torch then try to turn, if no go, 2-3 more seconds, then try....repeat as needed.

Use the smoke wrench

Caution with heat as the temps listed above may start to affect any heattreating. I would start with the chemical stuff.

Then I would use a wrench with 'cheater' pipe (an extension basically) to create a longer torque arm.

Then I would use heat.

YMMV

Use a propane torch, not oxy-acetelyene. It doesn't need to get more than about 400 degrees to soften & break-down the Loc-tite. Much more than that and you will be disturbing the metalurgy of the barrel. Don't ever get that crap near your guns (except trigger adjusting screws.

and even then, use BLUE Loctite

a thread loosener called 'Blaster' will soften red Loctite.

I soaked it in penetrating oil all day and she came right off by hand.

You got lucky. My buddy Chester was down in the basement and strained his liver trying to twist his brake off.
