In this thread I will be displaying the process I use as I add 2 part foam to the fincan of a preassembled rocket. In this case it is a Fiberglass Madcow Little John (4") with a 54mm motor mount. Since the internal fillets were done poorly, and this rocket will now be used for a level 2 certification attempt (already flown level 1 motors with it), I think it would be a good idea to make this modification.
Materials:
Rocket (preassembled)
Drill (1/4" bit) ~ the size of holes you tap depends on the amount of space you have between the motor mount tube and the airframe. (Bigger is better)
Deburring tool
Funnel or dispenser bottle with a small tip.
Masking tape and stuff to make sure you don't get foam on your rocket (it is VERY sticky).
The foam I am using is from TAP Plastics; X-30 polyurethane (2 parts).
