I just built a 24/40 with an E28-4T load.
Per the instructions I centered the grain in the casing, but this just feels wrong. The grain is free to move 1/4" to 1/8" in either direction. It seems there should be a spacer but one is not included.
I finally decided to seat the grain against the delay charge and leave all the space at the aft end.
Am I missing something? Why the extra space and no spacer? Does it matter if I push the grain fore or aft?
So many rockets, so little time, and money.
