DITTO on that... Details man.... We want details...

Ok, the back side I removed as much material as possible. I started out with a boring bar but I couldn't seem to get the right angle so I used a series of drill bits (like a the steps in reverse if you know what I mean) this way the gas is not shooting down the tube to the next baffle but spreading out when it hits the next baffle. When I made the OD and the hole I used a 4 jaw (the front of the baffle) but removing material off the back I just used a 3 jaw. It's easier to set up and not as critical.

Great job Jimmy.
What kind of stainless rod did you use for your stick welder?
Any idea where I can get it?

jimmym40a2 · Post by **jimmym40a2** » Sat Apr 11, 2009 11:05 am

probably any welding supplier could get it for you.Just tell them what your doing material wise what your doing and order it up!

What's the overall thickness between inner and outer sides of the stepped cones?

How did you turn the inside then, without having any outside/inside corners hit or anything? Did you start with a smooth cone and turn the steps from there?

jimmym40a2 · Post by **jimmym40a2** » Sun Apr 12, 2009 3:17 pm

Yep, Formula I made a smooth cone with a boring bar at an angle then used a series of drill bits to take out more material.

$25???? Where'd you get your materials?

jimmym40a2 · Post by **jimmym40a2** » Sun Apr 12, 2009 6:15 pm

One of the members of this forum sent me the materials and I paid the shipping.

I might have to try it that way. I was playing around with some scrap and I used a turning tool to get the steps on the outside, without starting from a smooth cone. or the inside, I was boring it to .100 less that the outer dimensions. It was a little confusing, so your way sound much easier.

Now you just have to make (or buy)some reduced capacity cases + the right bullet length for the ultimate silenced ammo

That is a beautiful setup Jimmy, you got that can duracoated yet?

Mageever · Post by **Mageever** » Sat Apr 18, 2009 6:52 pm

Rock on Jimmy! I'm freakin' jealous. I was plannnig on a rifle purchase next, but that thing has me re-thinking the caliber.

jimmym40a2 · Post by **jimmym40a2** » Sat Apr 18, 2009 9:10 pm

St33v haven't coated it yet but I realized my end baffle was very thick so I chucked it up and thinned it down to save some weight.I hated to get rid of the welds but to save some weight I profiled the tube some. Now its ready to be coated. Thanks for all the positive comments it's been a fun build.

GeneT · Post by **GeneT** » Sat Apr 18, 2009 9:22 pm

Lookin' great Jimmy. That's one mean machine! What I can gather from the video it works pretty darn well. Nice system you've got there. (And a good thing too, at only 6'7" you must get picked on a lot...

I'm supprised that sombody hasen't been on here yet screaming about how the step down exterior conture is a patent infringment on AAC's desgine.

Thats a sweet rig (the whole thing) you have their , what did the final weight of the suppressor come out at?

jimmym40a2 · Post by **jimmym40a2** » Sun Apr 19, 2009 8:21 am

James -I haven't weighed it so I will have to do it. My baffles are probabley way to thick inside. I didn't want it to blow up in my face.This was my first can and I learned allot.
I think AAC has applied for a patient so I doubt I violated any laws and this is a "one off" and I'm not selling them so I doubt they are worried about it. I'm not putting "front toward enemy" or anything to indicate that it's an AAC can.They could do a much better job.

Fudmottin · Post by **Fudmottin** » Sun Apr 19, 2009 9:11 am

The words "Front Toward Enemy" appear on the Claymore mine. I don't think that is an AAC product.

I realize that you are missing my point.

I miss points so many times. If only the bullseye was larger.
