2 major approaches.
1. Brute Force using steel and lots of weight. This will 'ring' at some frequency and IMO is not the best approach. Bridgebuilding for the amateur, IMO.
2. Ingenuity using real wood and sinking to floor. Rigidity is more important than weight. Ingenious design and attention to detail rules.
Early concept drawing with roller coupling to floor. Triangulation improves rigidity with minimal weight impact. It should be possible to modify to a ball bearing system.
Panel will be attach to frame with 6.5mil Teflon and a spring compression system to provide even pressure without drilling and no pressure points.
Intended material of frame would be 3/4" PlyBoo while current version of frame front is truncated, not straight.

Carbon fibre? I am not sure how one could source strips of this stuff, or how to "glue" or fasten the ends like hardwood. I do remember meeting a guy years ago in the motorcycle racing scene who made his own front fender from the stuff; he bought the cloth, soaked it in the appropriate resin, then baked it in his mom's oven. I am no help for you locating a 6 foot oven though.
No mention of Carbon Fiber, at least in my post.
TEFLON is just an idea. I have some 3M no.5481 which is 1/2"wide and 6.5mil thick with an adhesive back.
The PLYBOO I mention is Bamboo Plywood and is a 'manufactured' product. If you are curious, send off for some samples. The 'Neapolitan is the heaviest (densest) by far. The 3/4" thick version would seem to be most useful to someone wanting to build a frame for Maggies.
