Sorry for posting so much guys!
So today, I went to home depot to scout out possible alternate materials(i'm currently usinc PVC) for a lighter wing structure thats's just as sturdy.
My list of possibilities is as follows:
WOOD:
- .75 inch 6ft wood pole - about as light as pvc $ 3.00 per pole
- 5/8x1 3/8 wood stick - about as light as pvc $ 3.00 per pole
ALUMINUM:
- 1/2 inch, 96 inch tall C-Channel aluminum, 1/16 thick. - as light, if not lighter than pvc $9.98 per stick.
- 1 inch, 96 inch tall, flat, 1/8 thick. - as light, if not lighter than pvc, no pricing shown
- 1/2 inch, 36 inch tall(my only concern) aluminum tube - as light, if not lighter than pvc... forgot to copy pricing.
The aluminum tube is my most favored candidate, because i believe that it is lighter than PVC and also sturdier.
As for backplates of harnesses:
- Acrylic plate, 20x stronger than glass, extremely light, medium flexibility, $3.15
- Polycarbon from LEXAN, 250x stronger than glass, nearly unbreakeable, extremely light, minimal flexibility(but still a little flexible), $3.75
For the harnesses, I would like to use polycarbon because it is solid, and yet flexible so it will conform to the shape of our backs more. However, my only concern is the drill-ablilty and cut-ability of it. If anyone knows, please let me know.
Sometime over the weekend I will go with my dad to home depot and we will take a look again and choose a material to use! :P I'll give another report then.
On another note, when I was there, there was this guy who worked there that I kept seeing(well, i saw him about 3 times) who worked there... who had a big frown on his face. And his expressions didnt change... It was weird. When I walked through the parking lot he was also walking through the parking lot cause he was getting carts and he was like "..... have a good night......." when i over-passed him(we were walking in the same direction. And then as i got in my car and drove away(I was parked right next to the cart rack) he kept staring at me with the same frowny expression and i jsut sort of nodded @ him... o_O;;;
