I have another Big Daddy in the pile with some decent plywood parts I want to build for a L1 flight in May. For now I wanted to see how I will do by trying to build a test 29MM BD that might need tweaking.

A bit rough, but the fillets filled it all.

SO the assist from here if any can.
I figure I cut down the nose cone to about 2 inches and put in a ply bulkhead a bit up in it with epoxy so there is room for the chute and stuff since the 29MM motor mount was a bit longer than usual reducing the payload area. Also I believe I need nose weight.Does anyone know the weight I need? I am headed to open rocket to see what I can figure out. seems 3-4 oz will do it. Will be launching F engines from it in the beginning.
