Finally spent some time and drew out my design.

All I have to do now is send in my form 1 and round up materials.

I decided not to use a typical Bill of Materials and just noted materials on the front assembly. It's an A size sheet and BOMs are a waste of time for a 1 off project. Also, I think the gtol callout for runout on page 3 is incorrect, but it's obvious what I'm trying to say. I'm pretty sure when calling out a runout gtol, you have to reference a pair of simulated datums (ie, between centers). Also, there's a few grooves for orings in the drawing, but the drawing isn't calling out any of the soft parts like that.

Very nice. My CAD-Fu is not so good.

Rare to see 'real' prints that those who are interested could actually work from and build a can.

Got a "geek speak" to English translation on that?

Google: Third Angle Projection, Geometric Tolerencing, Basic Dimensioning, Datums, and Reference Dimensions

The rest is self explanatory.

Beautiful! I'm looking forward to (not) hearing how well this works. When do you plan to start building?

[James DeGroat]

Nice drawings

[Bendersquint]

Nice set of prints!

Side note......you do know that Autozone doesn't care those freeze plugs anymore right?

well, the can is for my max11 9mm/22lr...
Richard emailed me about a month ago that my number was up and it was shipping in two weeks. someday soon, It should be ready. Once I get through christmas and see the damage to myf funds I'll try to scrounge up $200. I hope to have the form 1 submitted before 2011.

If those freeze plugs are not @ autozone anymore, I'll have to order direct from Dorman or find another source maybe. It was on thier website as a product. ??

I did try (without success ) to find a thread that i read a long time ago
it was on a Swiss silencer forum
they had made a can with a spring like you are planing on

the baffles did move , but they did like that , they got better acuracy that way
but the long hole in the blast baffle might give you problems if it not goes fully back again ,then it will cant

think on how a pulse jet works , its the same , the gas moves out the front so fast it sucks a vacuum behind it , in a pulse jet this vacuum opens a valve and lets new air and fuel in

in you can this will not happen , the air changes direction , the spring is forced back

did you read the thread about a can with a big muzzle flash , seams it was sucking air in at the mount , then making a bigger flash than if no air could get in

making a surport on both ends of the blast baffle ,would prevent it from canting
just make the muzzle nearest part with holes in it

You will have to order them from Dorman, it is on the Autozone website but they are listed as NOT AVAILABLE. Doesn't make sense why they are not removing the parts but the same FP's are available from Dorman. They can't even order them in their system!

Looking forward to seeing how this turns out.

I will be watching this thread with great interest pnuemagger so if you don't mind, please keep me updated. I think your design is going to be quiet, especially on the 9mm.

I have one of the Max 10/9 Lage uppers. It is awesome and I think you'll love it! I also have one of Practical Solutions 22 uppers, but I think I would rather have a Lage 22 upper, but he doesn't make them for the 10's.

But I am holding my breath that he'll make a Max31 upper for the M10's that will be chambered for 7.62x25 and use Ppsh drums. That would be the cats' meow.

I believe those freeze plugs are carried by O'reilly's Auto Parts. If you have one nearby you might want to check.
Very nice CAD drawing. Be sure to tell us how well it worked.
