If you go to YouTube Randy Bragge has a very complete video on how to do the whole process. Start there.
Silincertalk.com is the greatest source for suppressors on the web.
And this is very true. http://www.silencertalk.com
Here is my video on making silencers.
A picture of one of my screw on 22lr cans.
A Ruger MKii
And a drawing.
My cans rarely turn out like I draw, but the drawing is just a guide so I know if things will work out. My first 22lr can used K baffles as shown in the drawing, but they can be very hard to remove when fouled unless they are shot wet and taken apart soon after using. Conical baffles with spacers come out much easier even when shot dry. That is why I sued them in my last two 22lr cans.
