Lots of holes

[John A.]

I know that Dr. Dater used ports in the face of some of his baffles. And of course, many others have used clips and ports with varying success.

But I'm curious if anyone has heavily ported the face of a baffle in order to allow pressure behind the face of the baffle and then pretty much catch it with no release point? Similar at least in principle to the outside skirt on a K baffle, but obviously still different.

My idea is more like the spool of bobbin on a sewing machine, but the rear baffle would be solid.

This would be going on a low pressure round, and why I think large holes would be more beneficial than small ports simply to allow more gas to go behind the face of the baffle and take longer to work their way through the stack. My baffle would also have a small cone around the entrance to the bore that would direct some of the gas entering the chamber into the port holes.

Anyway, curious if any of you guys know of something similar that has been done, and more wondering if it would be effective or more of a waste of time and effort.

If no one has tried anything similar before, I'm gonna call these "Tone" baffles LOL

interesting idea...

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 coaxial volume and put some ports on the opposite wall. It would take experimenting, to find the balance (I know, obvious thought )

Silencer design has been at it for over a century, now. It would seem that the most efficient way to deal with the gases are to redirect them, instead of trapping.

[John A.]

That is solid advice Trex.

John A,

A variation on the spool 'baffles' was proposed but never patented in
the 1960s was a radial ( thing of pizza slices ) chambered
baffle stack by eliminating the central tube. Like making egg crate
joints.

Rough idea:

Stack the spools in your image. Consider each 'round floor'
floating as you have eliminated the central tube.

Cut from outer circumference radial slices about ¼th way into center.

To support the levels you make complimentary rectangular vertical rectangles
with slices that are cut the same ¼ th way in. Round Egg Crate Cuts.

This 'corn-cob' stack now is rigid and supported.

Bullet passed through central tunnel;
gasses expand into each pie-shaped slice ... fast in, slow release out.

Easy to disassemble and clean.

Many other 'wacky' designs were conceived but never published.

[John A.]

Historian, your knowledge of suppressor design never ceases to amaze me.

What I have in mind is very similar to the bobbin above, with the addition of a small cone around the bore which will redirect some more of the gas into the round ports.

I was also thinking of making enlarged diameter around the circumference of the ports to give the ports more surface area to help create a little more "scoop" to further maximize how much gas can be redirected into the chamber over the bore.

And if desired, would leave an area behind the face of the baffle to install copper mesh too.

... I'm getting flashbacks of the sweet potato from some of this...

[John A.]

OMG. I had no idea that how that was made.

Ewww.

In looking around for a clear image of the potato's internals, I found some updates on James' pricing and other related stuff. Seems this baby has come down from $5,000 to a mere $3,000. And he's got a new one which he describes as as something like a Hiram Maxim redux. OMG indeed. Best metering information I could find was someone reporting 5dB louder than an industry standard rifle can, which surprised me a little. My guess, in writing back when it came out, was 10dB louder than an average commercial can. Still nowhere near his initial claims of around 89dB with supersonic .308" of course...

[John A.]

Yeah, I'm not one of his fans for sure.
