As a professional engineer for over 18 years, and now part-time as a hobby - I have clocked up over 41,500 hours on lathes, tool-making and hydraulic engineering. As you might imagine after this length of time and experience - engineering, lathes and precision tools have become natural extensions to my hands and fingers. Being ambidextrous and also having a very accurate eye for symmetry and close tolerances, I actually need to express my creative drives through continuing my craft. Although it is good to earn some extra money to ease our large family budget (6 children :-), I mainly continue engineering and crafting custom suppressors for the challenge and sheer satisfaction of making precision kits that my customers appreciate and value.

Suppressor below - threaded for full take-apart, this silencer has custom inbuilt muzzle-brake, 20 internal suppression ports and engineered to a tolerance of 1/100th of an inch.

Below - this is some of the internals that I have made for my own suppressor - for my BSA .22 PCP

Rifle is running at 1000fps - just under sonic, and at 3400psi - meaning there is an enormous amount of pressure coming out of this baby!

I am experimenting with a double acting reverse flow venturi design. This unit looks like a bowl sitting on a base. The underneath of the base is also concave. When the end-cap is installed at the precise measurement above this unit, it produces a continual loop vortex of the pressured air within the chamber, and forcing it back down the barrel to cycle again - and in the process slow the rate of flow and release it out through the muzzle-brake at a much reduced dB volume.

 

 

 

 

 

 

Engineering Process

Every Elite silencer is crafted and engineered from high grade solid aluminum rod.

Aluminum is preferred above stainless or Kevlar - due to its ability to quickly absorb the hot gasses that are responsible for much of the noise experienced with rim-fire shooting. It works especially well with sub-sonic ammunition.

Every piece is precision hand-crafted - I do not use CNC or automatic lathe attachments.

This photo clearly shows the craftsmanship that goes into finishing the outer tube - threaded for end-cap as well as custom hand-grip.

End-cap, threaded and crafted with a Venturi reverse flow suppression spacer.

Perhaps I am a little biased - but I still appreciate the beauty and craft of this engineering art.

Each custom Venturi suppression spacer is double sided. On one side is a funnel shaped cone, that slots into a concaved recess in the spacer below, and in turn has a concave chamber at its other end.

Every Venturi spacer is hand crafted, starting with a solid blank, machined in steps and then finished with a file, sanded by hand and polished

Here is the spacer from above, in its finished form. Operating to a tolerance of 1/1000th of an inch - the final sizing is too precise for my precision lathe, and must be completed through careful buffing and polishing - resulting in a mirror finish.

The finished unit. I craft as many or as few spacers as are needed to obtain maximum suppression. Spacers should not be evenly spaced throughout the silencer, but need to be of different and usually decreasing size. In doing so, the owner is also able to fine-tune their silencer into a configuration that enables maximum efficiency and suppression.
