Re: Input On Steel chassis w/wood inset
The price of true structure carbon fiber can be a budget buster. Mcmaster carries a selection of fiberglass pultrusions that are more budget friendly. Instead of thick wall material. Try tube in tube construction with 2lb expanding foam between the tubes. As this post was about wood and steel, I'll stress again that birch plywood is tough and can be reinforced with fiberglass. You find that the end result is a material that has better properties that polycarb and is lighter. Make sure the plywood is solid birch ply's and not a filler in the center.
