Past coupla years I've been starting my own manufacturing company making Muzzle Brakes of my own design, and Have Now been given the Old_painless stamp of approval.... Not to mention the approval of everysingle customer who's purchased or tried my brakes... Here's a link to the newest chapter of JSR...

Ok, Sortof of topic, but not really... Today I was running some 1"thick aluminum plates with various features and the like, with an o.d. on one of the features 18.500"-18.499", ok .0005"+/-, no biggie... Ran them, measured them 18.4993"(they still get anodized and spec'd dimensions are after plating...

Muzzle sweeping is most certainly NOT ALLOWED..... And the shotgun in question was cleared, and with open chamber, and also pointed at the ground, not my @ss as it appears in the photo... When we have gun days here at the farm, guns are clear until you step to the line, and cleared before leaving th...

It's actually one of the first prototypes that RIA produced...

Here's some of my handi-work on muzzle brakes for firearms...

I should be able to whip up some more wickedness, since for the past 6 months I've been working as a machinist in a shop that makes a lot of high end components for the aerospace, medical, and automation fields... I've been manufacturing firearm muzzle brakes of my own design here lately, and now th...

Popping in to say hello... I'll be looking to start some new projects very soon.... I'll be busy reading the 3000 posts I've missed over the past year...
D-Hall, glad to see work is going well ...

I answered L&L's post... If it stays on topic leave it up so i can answer inquiries on my absence... And as soon as it warms up enough for the co2 to go from solid to gas(well it seems that cold lately), i'll see about getting some vids and stuff up...

Going from temp and being unregged, I'm guessing around the 1200psi range... the main reason for the low rating of the qevs is the "piston" in them, and service life in industrial applications... the piston in some instances WILL fold itself backwards upon piloting, allowing the chamber pressure to ...

I'm alive and well... Got unemployed thanks to new owners at the dealership... I live in the boonies so i haven't had acss to www until now(finally got a cell tower close enough to get wireless internet)... I'll be catching up on posts soon... @jsr Dodgie launchers... Hello pot, I'm kettle... lol

JSR - always keen to show that he's not compensating for anything

He's just working in scales that are familiar to him...

I know I said otherwise in my earlier post, but I think your chrony is wrong.... the reason I say this is because the coppercane shooting ".40shellcasing/wirenut combo" projectiles at 1085+ fps are stopped by 3/8" lexan motorcycle windscreen materiel when fired from 30yds on a warm day(on colder aka...

19/32 is what you want.... 1/2" will be way too small...

Bullet resistent media (glass/lexan/etc) are designed to dissipate the energy through deformation(lexan) and energy consumption through cracking... On such a small piece there isn't enough surface area to effectively consume the energy before the glass was destroyed... I believe most ratings are bas...
