Re: Which Engravers are people using?

Most places that do awards and trophy's plus many jewelers and pawn shops have the equipment.If the tube is carbon steel electrolysis is fairly simple for even the kitchen table hobbyist.
If the laser removes metal then you can use that meathead too.

Good to see you online its been awhile.

Re: Snorkel Suppressor Design

Historian: The suppressor in the patent is the great grandchild of the coaxial suppressor AKA: AWC MK-9, MK-9K and a few others.I have seen these using cone,K and M baffles.While old school I know this design works wonders on 9mm buzz guns and others that respond well to large volume design.These ar...

Re: Modeling supressors

The Tesla valve can be used in suppression.The best was stacking flat discs with valves etched into them.This formed a soft tube where gases escaped through the side.We tried to emulate the early porous aluminum suppressors this way.It was also reminiscent of a motorcycle muffler called a Super-Trap...

Re: Stepped Baffles versus Cones

Yes the stepped cone is better in terms of db numbers over the straight cone....without porting ! Clipping and or base porting is almost a new science and will alter performance of either baffle. I have been told that steps are best for high velocity ,my studies show they also work well for low pres...

Re: Turbocharger baffles

These turbo baffles feature a long throat and that tends to make bullets wobble.Baffles should strip gases from the bore line and not line them up for the next bore hole for maximum suppression.Disruption of gases in non symmetrical ways helps retention of these gases. Cones with some porting is pro...

If the aluminum "jacket" will be exposed to the pressure a 50bmg will generate then the classification changes from suppressor to fragmentation bomb on a stick with a fool holding it.

Re: 30 Cal Form 1 Project

You might be able to lessen FRP and increase SPL losses with a reduction in blast chamber size ie: to tune the suppressor.You also might be able to create secondary expansion chambers through porting or the placement of spacer rings within the stack.

Sadly reflex areas in suppressors add the least amount of suppression but may help tune internal pressures to best suite a baffle type.Tubing passages within suppressors have been used in the past to dump gas into the rear of these "reflex" chambers to correct this deficiency.Just ask Dr Dater.
