Re: Feedback on .22 Mono-core design

Looks much lighter then the last ones. Probably more effective sure to volume increase. Symmetry should maintain accuracy and minimize poi shift. If you don't mind me asking, why are you doing a monocore instead of a baffle stack? I was planning on doing a monocore for my first build but the more I...

Re: AMAZING RESULTS WITH "THE DIP"!!!!!!!

Go to a chemical supply store and get a gallon of 30% hydrogen peroxide dilute that 50% with h2o then mix with vinegar, it will boil!
If the can is really caked up change the mix every 12 or so hours until clean. I've had to change the mix as many as 5 times until clean, and it will get there.

Re: Leidenfrost Effect for Next Generation Baffle Surfaces?

Honestly it's hard to imagine anything that would revolutionize silencer designs. While there are many distinct challenges involved the general physics is well known. The heat and fouling involved also limits both usable materials and the design . Yeah, it's all about volume. Projectile noise can b...

Re: Single point threading titanium tube

A trick that I learned for hitting the mark to engage the half nut is to keep back from the part quite a ways. When the mark gets close, lock the nut. If you missed, then you have room to open it up, back off a bit and try again. Once you get it right, allow the cut to be made, you just have to wai...
