Is this concept printable?

Thanks for the feedback, Mr.H

The design with the 50 mm nose OD exists, if you wanted to try it. The one you have has the 40 mm nose OD.

That said, if one gets the same dB readings for different systems, one needs to consider the possibility that your meter is so close, that it is maxed out to the same reading. Perhaps you can try again at twice the distance from the meter? Ensure that the meter is not so close to the trap that the trap's noise is louder than the report, or that would measure the same for both configurations.

What I didn't say in my previous post is that there was no discernible reduction to my ear, regardless of the dB reading. Both shot strings were loud, and both strings sounded the same to my ears.

I think at this point I'll pass on the 50 OD. If I change my mind, I'll PM you. Thanks again!

Makes me wonder if my Tesla Valve layout needs to look more like OldSpook's. Something like this:

Well, dang, sorry to hear this. I was expecting more reduction, based on sheer air volume alone, not to mention more sophisticated guts. Weighing more and sounding about the same, understandable it's a no go. I have a few questions I'll ask in a PM.

I have designed another version of this insert for Mr.H. Rather than stuffing the tube full of Tesla Valves, it incorporates a section similar to OldSpook's Ember LDC: There are two Tesla Valves, separated by a significant open chamber.

Ahead of the first TV is a reflex air stripper to feed the rear of the shroud, and to reduce the exposure of the pellet to the initial uncorking turbulence just ahead of the barrel muzzle.

Following the Ember-like TV section, the large vented frontal chambers are retained from the original design.

I hope that OldSpook sees this copying of his design as an endorsement, rather than as theft. This copy would have been closer to the original intent, if the tube ID was 33 mm, rather than the 22 mm in my design. So, this means that the smaller tube ID does not support as high a bypass vent area ratio, compared to the baffle bore diameter as OldSpook deems ideal.

That said, I think it may be worth trying this version to see if it is better or worse than the version Mr.H has in hand. I sent the print file to TorqueMaster, should there be interest.

I'm still on the fence on this. Torque asked some Q's in a PM. I have a couple Q's into him.......

What can you lose?

Looks like V.2 is on the horizon.............

Time for an update on this thread. I got the V.2 unit the other day, plus another unit for a .22 Daystate Huntsman Revere.

I’m calling the V.2 unit S-TrQ

What did you order / receive airgun related today? Thread

A broken car window and a banquet of flowers for my wife. Trust me. It's airgun related.😉😉 😳
