I made a ...rather unique... baffling system for my Executioner.
However, when I talked to the guy at Hobby Town today about my system, he thought that the holes in the sides of the motor mount tube might not be a good idea. He said directing the ejection gases sideways like that would probably lead to it just blowing the sides out of the body tube, rather than pushing the nosecode out of the top of the rocket.
He also thought the 3/8" holes I put in the top plywood centering ring I added would not be large enough to let the ejection gases through quickly...resulting in the rocket either spitting the motor out the back at ejection or, again, just blowing the sides out of the body tube. Unfortunately, with the rocket fully built now, I have no way to get at the top centering ring to make the holes larger, or to remove the "cap" I put on the top of the mount tube.
What do folks on this forum think? I'm going to attach a picture I took of the top baffling before the rocket was finished. These holes look awwwwfully small...will the ejection gases go through these fast enough to kick the nose cone off?
