The upper connective in the tripple tree would be a threaded rod or machined better equivalent, hardware bonded to the center of the TV. The reason you would do that is that the steel or Al will interface better with the top tripple tree, and make it possible to endlessly remover the top plate.
As far as the wraps are concerned I was only suggesting one at the top of the TV where the rod is bonded inside. There will be a bending moment there, and the rod could split out the TV, or even it could split due to moisture issues, where the TV dries out, and cracks as a result of the material in the center, though hardware bonding will minimize that. all these wood materials are real strong in certain respects, but poor in split resistence.
The way you hardware bond a stud into some wood, etc... is if it is 1" diameter, then you might drill a 5/8" hole in the end and use a 3/8" stud, the rest is taken up with epoxy. You want to leave as much wood as possible but also leave at least 1/8" for the epoxy. This fastening system is used in high performance aps like wind turbine blade up to 160 feet in diameter held to hubs by studs bonded into the endgrain wood fiber, and all sorts of sailboats etc..
I've been doing wood and bamboo comPosites for 30 years, but your ap is all new to me, and I don't Know this TV stuff.
"this still leaves me the issue of aquiring the plates. i dont have any machining tools at me disposal. i could borrow some time on a drill press but thats about it. how thick of plates should i use? could i cut it with a hand jig saw and a metal blade? what if i could use a band saw? how expensive would it be to have them machined?"
If you are going to do it with tripple trees you are stuck with the plate issue. I would use 3/4" Al, on the assumption you want to look beefy, and you need significant socketing to hardware bond the TV in there, might not even be enough. You can cut Al with a wood bandsaw, or cut it on a metal bandsaw. You can cut it with a high qualityu jigsaw and correct blade, though 3/4" is pretty thick. You can hole saw that with a drill press. In my neck of the woods CNC work or machining are both very expensive. CNC the costs only come down with volume. There are a lot of products involved, CAD drawings, G-code file, machine set-up, then running the parts. Manual machining is slow, and also expensive.
It could be done in composite, though the design work gets more difficult and you would have to be careful to maintain accuracy.
Forks need to be real accurate, or the bike doesn't ride correctly. However, wooden jigs can provide that accuracy. Particularly where stuff like hardware bonding or composites are concerned, because there aren't any heating forces pulling at things.
