Wow, your doing a good job of stacking them holes. Not sure I could keep them so straight even with a drill press. You'd think MSR would pick up on this.

I think if you re-read, you'll find that the parts (except for a 1" section of copper tubing) are manufactured parts for the Primus 111 stove.  

Yeah.  You are right ... my tests on creating these parts myself didn't result in the holes all cleanly aligned.  I think I'd need to make a jig to get that level of accuracy.

As for MSR looking into this adaptation, I would think it to be a no-brainer.  The roarer-type burner is a design that is prominent in Primus stoves, so for MSR to use the "flame/sound disperser" would not likely involve any more copyright/patent issues than the burner itself.  Of course, I didn't run my project long enough to determine if there is a fuel efficiency difference or the BTU output is modified, but I would doubt any significant impact.
