I'm sure you have thought of this - but the nylon lock portion doesn't look like its engaged on any ifs the nuts.
Also - interesting eyelet. Where did you get those?
I have a question. Technically the nose cone is going to be fiberglass. Since there is a 1.5" section of the coupler that will be going into the base shoulder of the nose cone. Will RF signal go through it if the antenna is in that area?
What is the rest of the nose cone made of?
The nose cone is fiberglass
RF signals will go through fiberglass just fine. It's carbon fiber and metal that you have to worry about.
Thing is the body tube is carbon. Majority of the blue tube coupler goes into the carbon tube, but there is that 1.5" section that goes into the fiberglass nose cone. If I were to place the pointing end of the antenna in that area, will the signal still be able to go through?
It should. I've read about some rockets that were all aluminum except for a small patch on the nose cone for the tracking antenna.
But you should test it on the ground first to make sure
Just did a quick catch-up scan of your thread and it looks awesome so far! Excited to see it finished.Two down one to go. I'll do the last one next week. It really is a pain in the neck to do. Hopefully I can get the dura-grit sanding file by then.

Those fins look great! I'm curious, how'd you go about getting such a symmetrical airfoil on those?
I wish they were that symmetrical. .
Why don't you try fastening the sandpaper to a non-flexing solid surface, and slide the fin across it for shaping. You will get consistent-repeatable profile.
Like the photos show here, just use a wood/g-10/metal shim to slide fin across, that will yield the bevel angle required . Distance between the 2 guides can determine bevel angle tweaking.
Stock in back just hold paper in place and serves as guide to slide against. Anything straight can be used/clamped to level surface.
