Fin can coupler is in...
I’ve decided to put the fwd rail button half way up the upper segment of the fin can rather than into the fwd coupler - for a 2.8kg rocket, it seemed like it could be a lot of stress on the fwd rail button loading and unloading if it was too far back with the rest of the rocket acting like a 1.5m lever on it.
Because of this I’ve opted to do the coupler and Fwd segment of the fin can, as I want to do rail buttons before the fins, while I can still get into the back of the rocket without rogue epoxy from internal fillets getting in the way.
I’m now off to the hardware store to get longer rail button screws (not for this project, but I keep meaning to get some) and more isopropyl alcohol and acetone..
(Incidentally, I’ve made the last 25% of this bottle last as long as the first 75%... something about running low that makes me more conscious of not over using it... [emoji12])
