I'm really impressed that good old low tec wood can work so well. You proved it man! What does that whole setup weigh? You geometry seems pretty good from your video. Can you post details of all the relevant dimensions? I just may have to get on the bandwagon!
The whole setup weight just over 5kg,
Lighter than all three commercially available one that I have,
The Rush Randle Aluminum
The MHL lift Carbon veneer
The Carafino Carbon Fiberglass
The floor tile is 1 foot square, so you can see how big they are.
