Ya I mean the whole front end could be done pretty easy with it. That's what I'm working into. It's all a balance between getting customer stuff done and still having time to develop new things. Being a one man show can be tough in that way.

Here is a few pics from making a top tube. I partner with a company and have full access to their facility and tooling. A few things include a clean room, plotter, 5 axis cnc router, and autoclave. A video is coming out soon showing the process here.

https://giant.studioI'm not sure exactly what caused them to stop making the honeycomb bikes but I will say that it is much more work, cost 2-3 times as much in material and I can see them having some impact resistance problems with the way they were making it. With only 1-2 layers of woven as the outer skin it wouldn't take much to puncture it. I'm using a very light weight 80 gsm uni that allows me to work in the different fiber angles needed to balance bending, torsional and impact loads a down tube may experience without adding too much weight. This fabric is half the weight of a standard uni allowing twice the amount of layers in the same weight. Once again that makes it much more labor intensive because you have to cut and lay up double the material but it results in a better product.
Thanks for the answer. You mention down or top tube as the main applications. Do you see stem or bars being done with honeycomb sandwich? (I tried hard but never manager to see the frm black hole stem, unsure of construction).

Thanks! It was a road out by palm springs that we found. Those are the mountains where the tram goes up in the background.

Lets do it!

Brilliant paintjob and a amazing video. But it's a kind of a pretty hard listening comprehension for foreign guys!
