Now for a bit of work on the tail cone. I used an xacto to cut away most of the end, so I'd have access to the fin tabs, and be able to insert some sort of aft CR. This plastic is really thin, and a sharp #11 blade cuts through it far too easy - it'll require a little filling when done.
A short length of BT-80 will be used as a reinforcing ring, it took a little trial-and-error to get a tight fit, by slicing a progressively larger wedge. After roughing up the inside of the TC, I smeared a thin layer of 30m epoxy, inserted the BT-80 piece, and pulled it back tight against the aft lip. This seems plenty strong, and should provide a good gluing surface for an aft CR. The aft CR will need to be some sort of 2-piece job to get past the taper - I'll figure that out when it's time.
