I wonder how often golf comes up in this forum, but I am going to rip that band-aid off...
Some backstory:
I have setup a golf simulator in my garage. The sensor that makes it all work is an Optishot:

It works in unison with a computer, and has a set of lights and sensors behind and after the ball. It tracks the club, not the ball. I use a third-party replacement turf to add depth to the hitting surface. I can take divots with my irons because the turf is so thick:

To raise my feet to the same level as the turf, I built a hitting platform. The one I have used for two years was just proof of concept; 1/4" OSB sandwiching some insulation. The simulator has worked out wonderfully, and I want to make a new platform, hence this post. I have reviewed many threads but this one was by far very informative and I thank you guys for this info: http://www.sawmillcreek.org/showthread.php?174228-How-Thin-Can-I-Make-a-Torsion-Box
Project:
I want to build a torsion box that I can raise and lower in my garage on a hand-operated pulley system. So, weight is a consideration. The total height from outside skin to outside skin will be 1-1/2". I would have to add structured blocking to receive mounting hardware in the corners, and that I can figure out. The platform with be 5' x 5'. Here are my questions:
- To lighten the weight, can I use 1/2" or 3/4" plywood instead 1/2" MDF for the webbing?
- Will glue and brads work to adhere the skins to plywood webbing?
- With 1/2" skins, is 1" webbing going to be enough structural support?
- Being larger than 4' x 4', will skins made up of two pieces be alright?
Thank you for any feedback.
