Ok so I like to have some fun from time to time.
This is a rocket I built out of an Aerotech G80 motor casing.
This one really gets a rise out of the RSO.
Here you can see it with a motor in place. I fly it on Estes C motors.
At the bottom the gray part is the motor with electrical tape around the part sticking out. This was after a flight, before the flight the tape is black and looks just like a nosle sticking out.
I usually insert a copperhead igniter into the estes nosle and tape it in place to complete the mock up.
It has G10 fins and a brass 1/8in launch lug. They are surface glued with epoxy.
I roughed up the surface with sand paper so it would bond better.
I had to mask off the area where the fin would bond so that I didn't damage the Aerotech label. I then masked off a bigger area where the fillet would be and scuffed that up but payed particular attention to where the printing was so that I wouldn't scratch it up because you can see the printing through the epoxy fillet.
I used my masking technique to do the fillets because you only have one chance to do them right since you can't sand them.
The centering rings and 18mm MMT are Estes issue as is the small orange chute.
Measure how far the nosle sticks out of the motor before you cut it off. You want the estes motor to stick out this far so that it looks like the nosle.
Position the motor block so that the motor sticks out as far as the nosle did.
There is very little room so I used Kevlar for the shock cord. This was attached directly to the MMT and the other end was frayed and epoxied into the tip of the nose cone.
Because there was very little room I tucked the shock cord up in the NC. Then the chute has to tuck into the nose cone, this should be a loose fit with maybe some powder on it. I also used a nomex chute protector that was shoved into the BT above the motor.
Friction fit the moter and wrap the part sticking out with electrical tape to look like a nosle.
Enjoy
