You can buy the solvent cones and cups for ~$20/ea. I'm not sure those turbines are going to be as cheap or that they'll perform any where near what you're envisioning, with or without holes drilled in them. I don't see those blades forcing the gas to the outer wall anymore than a cone feature or ke...

I don't see how you expect this to perform beyond the abilities of the base structure, being a radial baffle. As I'm sure you're aware, those fins would be rotated, at high rpm, to compress a gas and force it into a tunnel. This is exactly the opposite of what you're trying to accomplish with a supp...

I'm looking for 1.625 tube and end cap. Any suggestions? DM is out and has been.

I've never made baffles from it, but have used barrel cutoffs for thread protectors and brakes. Cuts great. You should know your machine so push it till you can't

My memory on it is hazy, but wasn't the issue with the Sig brake that it had a shoulder at the rear and a nut at the front, thereby allowing it to be made into a suppressor simply by installing a tube? Same thing that got a bunch of similar Chinese "muzzle brakes" seized recently? There were 2 big ...

Sig expressed design intent for end users to put tubes over their muzzle brakes This is irrelevant and never revealed in the actual court case. Sig presented a design that had a purpose other than that of a silencer. Which makes it, by definition, not silencer. If you read the court case, the only ...

All you have yo say is you were making a muzzle brake.

Ask Sig how well that worked-out for them

What do you consider a "long stick"? From a metal supplier, sticks are usually between 20-21'LG. You can't usually get anything over 6' shipped to you, it'd have to go freight$$. I checked my local supplier and they have nothing in manageable lengths, in their drops section. Check out these guys. Th...

I'm not aware of pipe being available in 17-4. Are you referring to Tube? There was a member here who used to sell it, to other members. I think it was Bender? Have you considered welding the stack, sans tube, or using Ti? Ti would probably be the same cost as a small quantity of 17-4 tube. A tubele...

If you really want a 50BMG can, slow down and rethink. 2" will not be enough. I wouldn't go smaller than 2.5", unless you've made a couple and have experimented with designs. A 50bmg having a chamber pressure equal to 55kpsi and a barrel length of 26" Your muzzle pressure will be ~11kpsi or roughly ...

If the majority of the links to the pics in the archives weren't lost, you'd see this design has been tried, in more ways than one. The idea is sound, but it didn't look to pan-out. At least, not for those experimenting. Maybe there's avenues that weren't tried? Possibly, add some packing to the coa...

Cant see the pic. thought it was because i was at work, but cant see it at home either.

Hmm, works on all my devices.
Anyway, here's a link

Cuz pics of catheads



I just threaded a junk of 1018, so it fit the spindle.
Welded a piece of 2-1/2 or 3" CS pipe to that.
Turned the OD true.
D&T all the socket-head screw holes.

I'm with the crowd, on this one.
It's not an SBR until assembled, this is from ATF's mouth and case law.
Also, there's no intent to build an unregistered NFA firearm, as he's pinning it to legal length.

Honestly, just check ebay, for the small stuff. Here's one

I think 1.5 x 9 is going to be a bit small. The Bowers Vers 458 is 1.75 x 11.25. That's >150% larger internal volume. As far as pressures, I wouldn't be too worried. I think the 458 chamber Pmax is something like 35k. That's nothing. Coupled with a large chamber and bore volume, your muzzle pressure...

Historian, I somehow knew the exact pic you linked, from "1950s Salesman station wagon", alone

How about making the tube a tad shorter?

The Leonidas, by Liberty, is what you want to search for.

There are sites that sell components called "solvent traps". You can buy these, to form 1, and design your own stack.

Surefire isn't selling you a tube. Not only would it be illegal, but it's part of a proprietary system.

304 and 316 always want to warp. You need to either design around it or compensate with weld fixtures and setups. If need be, I'll attach large Al blocks near the weld, to absorb heat. I always do a couple test pieces to ensure I have the setting correct. The fixture works perfectly. It took a coupl...

I do have a question for T-Rex that I think will also help the OP. How much did your 5.56 can move after welding? Did you have any noticeable distortion using your DIY positioner? Any lessons learned that you can share on the welding? While I'm sure the parts had some final settling, it was nothing...

I got the best chips from interior profiling and an, IIRC, SCLR insert. For the exterior, I do believe I have CNMG. My insert game isn't very strong, but I've found what seems to work and what doesn't. I have a good selection of inserts and bars, but have yet to spend a dime. I received a good deal ...

My SB 9A is from, IIRC, 1947. I was able to use carbide tooling and take quite generous cuts. It's a nice metal to work with, especially for being stainless.

Do you mean "Austenitic" ?
