392heminut Posted March 11, 2015 Report Posted March 11, 2015 (edited) Okay, I did my form 1 a little over 3 weeks ago so if it doesn't get kicked back because I did something the BATF doesn't like (THAT never happens!) on the form, I should have a stamp in a couple of weeks. I ordered some 'solvent trap' parts from SD Tactical that came in today. First up is the 7.6" titanium tube, 1.5" O.D. Next are the endcaps, the one on the right is the titanium adapter end to fit SD Tactical's muzzle break and the one on the left is the aluminum outer endcap which is undrilled at this point until I have my stamp in hand. Baffles will be made out of freeze plugs but I won't get those until I have the stamp in hand. I also have to engrave the BATF required info on the tube too. I'll update this with more pics as the build progresses. Edited March 11, 2015 by 392heminut
98Z5V Posted March 11, 2015 Report Posted March 11, 2015 Brother, who the hell is gonna engrave Titanium for you?! That stuff is harder than woodpecker lips! <laughs>
392heminut Posted March 11, 2015 Author Report Posted March 11, 2015 (edited) There's a 'smith here who makes AR-15 barrels for Brownells that can do it I'm pretty sure. If not I can send it to a guy that's doing them for SD Tactical for $25. Edited March 11, 2015 by 392heminut
98Z5V Posted March 11, 2015 Report Posted March 11, 2015 Did your Form 1 go personal, or to the trust?
392heminut Posted March 11, 2015 Author Report Posted March 11, 2015 (edited) Did it with the trust. I'm going to build a 300 BLK SBR next on the trust. 8" bbl. and a 6" direct thread form 1 can. Edited March 11, 2015 by 392heminut
ironmonster Posted March 11, 2015 Report Posted March 11, 2015 Find a laser engraver in your area, no problem with Ti. Has to be an engraver though, the trophy shop lasers wont cut it.
MikedaddyH Posted March 11, 2015 Report Posted March 11, 2015 Quentin Defense in Gilbert can engrave it. Don't know what they charge.
Rsquared Posted March 11, 2015 Report Posted March 11, 2015 You've got my full, undivided attention here Larry. Lookin forward to see how this comes out.
planeflyer21 Posted March 11, 2015 Report Posted March 11, 2015 Brother, who the hell is gonna engrave Titanium for you?! That stuff is harder than woodpecker lips! <laughs> Well, probably NOT a certain person who just sold their CNC in S. AZ. :eek13:
392heminut Posted March 12, 2015 Author Report Posted March 12, 2015 Mike, that's a pretty impressive kit there. Those baffles are known as 'K' baffles and the general consensus is that they work better for low pressure rounds such as pistol and .22 LR. Cone or 'M' baffles seem to work better for the high pressure of rifle rounds, at least according to those who claim to know more about this stuff than I do. The cone baffles I will be making with the freeze plugs are a variation of the M baffle. Hell, for all I know the people who are saying this stuff are cheap bastards like me and since the M baffles can be made with hand tools they think they are better! <dontknow>
AdamO Posted March 12, 2015 Report Posted March 12, 2015 (edited) Well, probably NOT a certain person who just sold their CNC in S. AZ. :eek13:I know, I know... Robo already smacked me around for it!! <lmao> But...I stopped doing the guitar business and its just taking up shop space. Its big! Has a 3' x 4' cutting area Its a great wood cutter and will do soft metals in a pinch, but I want something more compact and higher precision with servo drive vs steppers and an honest to God spindle vs using a router.

Toolndie7 Posted March 12, 2015 Report Posted March 12, 2015 That looks like a fun project. I need to move out of this state, makes me want a suppressor dammit
george_995 Posted March 21, 2015 Report Posted March 21, 2015 392, I have been looking into this hard for the last year or so. NFA poop really intimidates me though as far as paperwork goes. Here are some links I hope can help you. http://www.silencertalk.com/forum/viewtopic.php?f=10&t=130461 http://www.silencertalk.com/forum/viewtopic.php?f=10&t=81439 The one link isn't an sd tactical tube, but there is a lot of good info in tharrrr!!!
EasyEJL Posted March 21, 2015 Report Posted March 21, 2015 I wonder how the freeze plugs hold up over time
george_995 Posted March 21, 2015 Report Posted March 21, 2015 I wonder how the freeze plugs hold up over time This guy is from silencer talk, goes by the name sub_sonic.
392heminut Posted March 22, 2015 Author Report Posted March 22, 2015 I wonder how the freeze plugs hold up over time The one closest to the muzzle is the one that gets all the blast erosion. General consensus is that a muzzle break device alleviates a lot of it as the blast shield on the device takes most of it. Some guys building direct mount cans are using a valve spring retainer as the first baffle to act as a blast shield. You can't legally replace any of the freeze plugs once the can is built, only someone with the proper FFL can do that. There are some guys who have put over 1K rounds through a can with freeze plug baffles and there is very little wear. You can always rotate the freeze plugs too.
