really not necessary - just make a floor of firm 3/32 - balsa cross grain. back a ways
-to end of pipe
then a bulkhead with a soft tube from 1/2" dia blueline - to accept the spud on the rear of the can
Just so I understand what you are saying, the floor and bulkhead isolate the radio compartment from the muffler?
Happy New Year!
