Re: Stuck monocore

In a recent post I mentioned that testing showed that the fastest penetrating fluid is a mixture of 50% acetone and 50% transmission fluid. Works so fast on stuck rusted parts.

Re: Fun Images of Suppressor Cross-Section.

Discussed cross section images at club and a question was asked,
has anyone made a can with the baffles reversed.

What triggered this was the playing of a trumpet ... small hole, flared
tube, loud noise.Mega phone. Is there not a can out there
with the last few cone baffles reversed?

Re: Has anyone had problems with aluminum end cap binding?

First suggest you use Permatex Anti-Seize on threads.Prevents Aluminum=> Steel galling.

Second, after magnified inspection of threads, a light buffing with 4x Zero steel wool on threads
cleans up bad threading. Note, not for feint hearted. :)
