I've got the week off and have started my latest Form 1 silencer build. It is designed for a 9mm rifle (planning on building a 9mm AR soon) but should be fine for a reduced velocity .308 Win (my Ruger Gunsite has a threaded barrel). The rendering is shown without the outer tube which is just a 7.625" length of plain / non-threaded tubing.
On my previous build, I had trouble with threading the tube and end caps because of the diameter and the rigidity / speed(too fast) limitations of my 9x20 lathe.
I put cutouts on the edges of the baffles to try to get some rotational flow inside the can.
Specs:
Length: 8"
Diameter: 1.75"
Weight: 25 ounces (according to simulation)
Volume: 5.89 cubic inches
Threads: 5/8-24
Bore: .406 (13/32 drill)
All materials were purchased from Amazon.com:
Outer tube: 1.75" OD x 1.56" ID A513 DOM Tubing
End cap/baffle: 1.75" 12L14 rod
Fasteners: 4" 1/4-20 SS Cap Screws
Here is the flow simulation: http://youtu.be/zuWGQXacxDY
