For what you are doing bagging would serve no real purpose. The little joints are easy to fuss with and not over-epoxy. Bagging works best with larger products where total finished weight is important. If you use too much epoxy on one joint it means (maybe) a quarter ounce. No big deal.

It's hard for me to advise how you should set stands of CF without seeing the application. I suggest you make a couple of test joints out of scrap bamboo and test them yourself. That is half the fun of making anything anyway. Do remember that carbon strands (unlike cloth) do not bend, they break all at once. This can be very exciting should it happen on the prototype at 30 mph. Make test pieces first.

Truth be told, 98% of my CF work involved fabric in boat hulls. The only strand work I did was in wing paddles. It was simple work and I can't really say I learned much. I'm sure there are guys on the forum who have done more with carbon in linear form than me. There might even be good information at the library or on the internet.

Do not listen to people who say what you are doing will not work. The world needs nuts like you. Push on, and if it doesn't work out, no big deal. As a kid I started to make a submarine out of oil drums. The cops stopped me at the launch site. I still regret not having completed the project. Carry on, and down periscope!
