How do you deal with a three CR mmt? I suppose I could use a rubber mallet!
Steve has you covered if you are starting from scratch, but did you already adhere all the CRs to the motor tube? If so, you can try this (it is a bit tedious, but if the CRs are already epoxied on, it may be your best bet):
- Line the first CR up in the body tube and mark off the three spots it is going to hit the fin slots
- Take a sanding block and lightly flatten out the CR at those three marks until it slides into the body tube and past the fin slots
- Repeat with the other CR, if necessary
Using the method Steve described is the best way (in my opinion) when you have everything loose, but if the CRs are already epoxied to the motor tube, the flattening technique works best to minimize the amount of gaps you are going end up with between the CRs and the body tube.
Basically, you will end up with CRs that look like this (flattened areas exaggerated for effect):
