Thanks for the complement! Modern machining can accomplish truly amazing things. The 90% printed parts I have seen from companies like Mori are going to be the next step in that evolution. I'm looking forward to completing these 2 cans. I hope to find a sound meter to get some data on them when comp...

Thanks! It's coming along nicely. This weeks progress:

Making progress....

Here are the baffle blanks and brake blanks waiting to be finished.

I know, right!

After nearly a year of waiting for my own equipment to be available for my project, i will be starting the baffles this weekend. I will post some pics of the blanks when they come off the lathe. I still need to wait a bit longer to get them thru the mill with the 4th axis to cut the vanes. That will...

Thanks for the complement! I cant wait to start the builds, but unfortunately it may be a while. I just took on a huge job and the mill i need with the 4th axis on it may not be free until the end of this year. I should have all of lathe work done ahead of that though.

Much to my surprise, I got both of my form 1's back approved today!!! 20 days from filing to approval.

Reduced OD of baffles to 1.25 dia. Shortened brake Shortened brake to blast baffle The radial fins are .04 thick on the baffles. I increased these purely for manufacturing. The blast baffle fins are .05 thick. I wanted to increase the contact area with the spacer to minimize embossing & to reduc...

I've settled on this for the vane arrangement. The baffles have a tight tolerance on the interlocking features, but I will likely add some method to key them as well. Total weight as shown is 26 oz. Total interior volume as shown is 11.54 cu in. 1.75" diameter x 8.35" long, not including a...

I was only thinking about being able to rotate the baffles in different ways to try different fin alignments with what I already have designed, not mess with any spacing. That's the reason for the questions about the clipping style and orientation requirements.

While I'm fiddling with various vane configurations, I would consider making the skirts separate from the face so I can try different combinations. Before I consider this option, I need some feedback on the porting options and their respective requirements. The asymmetrical that I have been showing ...

I have that on my to-do list while i'm waiting on my Form 1

I need to choose between the staggered helix or the alternating helix design. The alternating design seems to me like it will have the most turbulence and resistance to flow. Considering the low pressure cartridge we are dealing with, which one SEEMS like it will be better? In my mind, the staggered...

As soon as I (we ) finish the design, I will know the length!

Trust or individual? I'm doing a trust. A couple of weeks would be AWESOME!
Of course I need to finish my design so I can file........

Hopefully I am getting closer on this:

Hows this:

All of the baffles now have a .020 land on the front surface.

Changed profile as well.
Top pic newest compared to bottom pic oldest.

Ok, totally had my head up my butt on this one. How about this:

Clip them like this: http://rs1077.pbsrc.com/albums/w475/Shawnson133/Mobile%20Uploads/20160525_125016_zpsa6vsuccb.jpg?w=480&h=480&fit=clip The goal is to let gasses enter easily that are flowing perpendicular to the bore, but restrict gasses flowing parallel to the bore. This baffle also ha...

Here are 2 versions of what has been discussed as well as detail of the revised clipping. Not sure if I got it modeled correctly or not..... https://i.imgur.com/ixTAmZc.jpg?1 https://i.imgur.com/u71PQKD.jpg?1 https://i.imgur.com/sdFlIQQ.jpg?1 https://i.imgur.com/UJAShDx.jpg?1 https://i.imgur.com/ABs...

My 12° taper with the 12 TPI threads locks on hard enough that it won't loosen on it's own, but I've never had trouble removing it. I simply crank it on one handed, remove with two. You mentioned earlier the 12deg was included angle, 6deg per side? Is that correct? I'll try them in front of and beh...

WOW! Thanks for all of the continued feedback. I'm going to tackle one thing at a time here with my revisions, so be patient with me. I'm going to increase the spacing on the baffles as suggested and model the zig-zag as well as the same rotation but not oriented. This last one would be easier as fa...
