Re: Machining 416

I heat 416 to a cherry red to stave off rust from forming.They also can be hardened with relative ease.Standard HSS or cobalt tooling and brush on cutting oil is all that is needed to machine.

To succeed in your quest you will need to hire some machine time and a welder.

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: #baffles and low/high pitch suppression designs?

Suppressors designed for supersonic ammo are often different than subsonic ones in the number of baffles used.Only a few of them can truly do justice on super & subs.Longer larger tubes even empty ones tend to attenuate low frequency's better than short ones.High frequency's may sound loud up close ...

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.

Re: Anyone experiment making high and low pressure in cans?

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. I'll...

You might try insert HSS tooling from AR Warner.The T-15 HSS cobalt tools will breeze through 17-4 and can be resharpened.While carbide is great for production work the cost can be very high for amateur work.Interrupted cuts and vibration are common with smaller machine tools and this kills a carbid...

Re: Why no stepped cones from major manufacturers?

I can think of several reasons why major manufactures don't use them. Every baffle design has a sweet spot in performance.You could alter each sequential baffle in line to respond to decreasing pressures or use a series of baffles that work better at progressively lower pressure .This adds complexit...
