Re: Titanium Hazard

I used to machine alot of magnesium dry because of the reactivity of the material. Standard procedure was a bucket of sand plus the ways had sand on them.You must be careful if you use a coolent as it might cause more problems than its worth.Do the homework first! You can't extinguish a metal fire o...

Re: Turning 17-4 (A)

You might try insert HSS tooling from AR Warner.The T-15 HSS cobalt tools will breeze through 17-4 and can be resharpened.While carbide is great for production work the cost can be very high for amateur work.Interrupted cuts and vibration are common with smaller machine tools and this kills a carbid...

Re: Fun Images of Suppressor Cross-Section.

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? I had the same notion while test-riding a Yamaha XS650 twin. The reverse megaphone mufflers note was highly sensitive to the exha...

Re: Why no stepped cones from major manufacturers?

I can think of several reasons why major manufactures don't use them. Every baffle design has a sweet spot in performance.You could alter each sequential baffle in line to respond to decreasing pressures or use a series of baffles that work better at progressively lower pressure .This adds complexit...

Re: kinda off topic 9mm question

The Navy used a +P+ 170gr 9mm in the MP5SD that was very quiet though the barrel is a ported design.I use a .38special load called the 200 police positive from the Lyman cast bullet book.The pressure is not even +P and it hits like a ton of bricks out of a two inch snubby.It is remarkably quiet from...

Re: Integral Suppressed Sten Form 1 Idea

I'm reading allot of nonsense about porting and the MP5SD.The porting position and extent was based upon making 124gr NATO standard munitions subsonic not anemic.The porting was designed to have minimal affect upon accuracy ie: shaving of bullets and jacket damage caused by other methods.The MP5SD i...

Re: Integral Suppressed Sten Form 1 Idea

I've had the pleasure of working on several originals and clones of the Sten over the years.If I were to build a semi-auto version the barrel would get ported for velocity control.Suppressor tubes can be made from D.O.M. tubing.K baffles or ported cones should provide plenty of suppression set up as...

Re: Two Form 1’s in the design phase

I am considering using A2 for my blast baffle and doing a differential heat treat that would only harden the tip of the cone around the bore to slow erosion. I could also use it for the mount/flash hider and make the tapered surface harder than 17-4 ever could be..... it would have to be tempered t...

If the spacers and tube are round you might need to hone the tubes id.A split dowel wrapped w/ oiled sandpaper should do the deed.

Re: 30cal Integral Bolt Rifle Build UPDATE 4/7/2019

A couple items I could use some input on. I've used a lot of different projectiles, for subsonic 30cal. I really like the heavy, HPBT SMK's, but they can get pricey and I'm just plinking. For 300blk, I've settled on the Leatherhead 220's. I've yet to try the Berry's 300 220gr Blackout Spire Point. ...

Standard is +.060 for asymmetric baffles. Symmetric ones can be bored much tighter.As stated other issues exist that result in poor subsonic performance.

Couple things you can do. Crimp with a Lee crimper. Use a faster powder. A jacketed bullet will raise pressure as will its weight.
