I don't have any pics of the complete unit yet , I just got back another form 1 Friday and I plan to take pics of all of it as it comes together. I have been playing with differant desgines and looking at patens from the top rated suppressors and have found that a cone or better yet a stepped cone style is the best for reducing the signature on high power rifles. I have made two with K-baffels and they worked well but the cones are more effecient on rifle cans. I reciently built one for a buddy for his 338 Lapua (see note below) , everything on the suppressor was made from titanium except the rear end cap and that was 316 for the sake of not galling as easy as titanium does. I have made three of my own two from 316 SS and one from 304 SS. I get a great deal on 316 bar stock from an old boss of mine and the seamless tubing can be had for around $40 a foot.
My next can will be all titanium , 3al-2.5v seamless tubing and 6al-4V bar stock for the baffels , over all wall thickness will be .095" and it will be fully welded so weakening the tube with threds is a non issue. The strength of titanium drops like a rock at temps in the 700 deg range but on a bolt gun it'll never get close to that , even on a semi auto it would be had and expensive.
My desgine is alot like AAC's , I use a thin wall tube for the inner tube to hold the baffels together then its press fit into an outter sleave and welded in place to give a wall thickness around .80" to .100". My baffels now have two small shoulders on them so that they can be pressed into the tube yet maintain even spacing and straitness , I then run a length of all thread through it with a nut and washer on each end to tighten the whole stack together for welding ,then its tacked so it won't pull then fully welded with a tig rig , so you have somthing like this
pic of the core:
The over all OD on this is .005" bigger than the tube used for the sleeve , the outer tube is then baked to 400 degs and the inner tube is frozen this generaly allowseither a slip fit or barely snug fit then its pressed together and when the teps equalize its as good as one solid piece , the ends are then welded and your done.
Or you can use one piece of tube and have your baffels just slip fit in them , this is how the K-baffels work.
here is a K-baffel I made
Shoot me an E-mail and we can disscuss everything alot further
NOTE : it is legal to build a suppressor for sombody else as long as they have their completer form 1 with them and they are presant the ENTIRE time , they also have to have controle of ALL of the orats kept with the form 1 at all times
