So I'm needing to now mount my MMT assembly into the airframe.
54 mm MMT
3 CR's
4" Blue Tube 2.0 airframe.
Have 1 CR at the far end, 1 just above fin tip mount point and then 1 will be at the aft (yet to fit as foaming the void in the can).
So doing a ring of epoxy on the 1st no problem using a stick to get it down in there. Then how do I get this 2nd middle ring as all access is blocked.
I will be using the expanding foam in the fin can if that helps.
Was thinking of using 15 min epoxy here. Giving me more work time.
Apply a thick ring inside the tube for the forward ring, slide MMT in until 1st is in past fun slots. Use a syringe to inject a band/bead/ring of epoxy and then push the MMT into final location. Stand the booster in the launch position so epoxy can flow back down and make "natural fillet" on the 2nd ring. Using IPA and finger inside the tube for the 1st to make make clean good fillet.
Confuse big time here. Never done a MMT with 3 rings before.
