Bulkhead

This is the forward bulkhead for an Estes Interceptor E with an upgrade to a 29mm motor mount.  This bulkhead is also part of an ejection gas baffle system so you won't need recovery wadding.  This bulkhead will recieve the 29mm motor mount tube on the backside and allow ejection gasses to escape on the front side.  Perforate the motor mount tube with eight 1/4" holes spaced 3/4" apart starting 2" behind the bulkhead.  The gasses escape the motor mount tube through the 1/4" holes and then exit the holes in this bulkhead.
