I have a GoLite Jam pack, but it's a size i don't normally need or want for backpacking (70L!), and honestly i'm trying to preserve it more for my "bug out" bag should the SHTF (the reason why i got such a big pack). Anyways, this is the basic concept. Buy, or make two Bamboo oblong type rings using approx 3/4 to 1 inch diameter type bamboo poles. Take some extra carbon fiber arrow shafts that i have lying around.
Drill 4 main holes into the outside perimeter of both bamboo rings, and another one in the middle of the front roughly half way between the other two, and put the carbon fiber arrow shafts in the holes creating a basic frame. (i would glue these in as well)
Then on the back, criss cross by notching, gluing and tieing two pieces of bamboo approx. 1/4 to 1/2 in diameter. (i will probably sand them down a bit flatter too). Then do the same X pattern on the bottom of the now 3d cylindrical shape, probably using a bit thicker and sturdier pieces of bamboo than the ones on the back (at least 1/2 inch diameter).
Then take some very fine/thin and lightweight pure Dyneema/spectra type line and do some up and down V patterns around the whole thing and especially making sure to wrap around the "joints", and wrapping the bottom more than the sides. Then, put my clothes/equipment into a heavy duty type trash bag for rain protection.
Questions: What would be a good type of glue, epoxy, or the like to use to connect the carbon fiber shafts into the bamboo rings? Whatever i use for the inside, i was thinking of sealing the outside with silicone adhesive.
2nd, what kind of shoulder straps should i use? Are there some good quality, but decently priced ones that i can purchase individually? I don't plan on putting too much weight inside the pack so i don't need heavy duty type shoulder straps, but i do want some durability.
3rd, have you ever seen pre-made Bamboo loops for sale before, and where? I think the hardest part of this project would be bending the bamboo into the desired shape. I have some ideas--cutting some fresh bamboo during winter, put it in boiling water to destroy enzymes and soften it up a bit, ram out the middle inner separating joint material, bend and roast slowly over my wood stove (i don't have a propane torch and won't buy one just for this project), but honestly i would be just as happy buying pre-made loops if not too expensive!
More over, has anyone ever heard of anything like this before? It all just came to me kind of suddenly and out of the blue one night, and i couldn't sleep for thinking about it.
Just guesstimating, but i think i could get the weight to be around 17 oz at most. Bamboo may be free, already got the carbon fiber shafts, dyneema/spectra type line fairly cheap (plus i already have some, but i want to use thinner lighter stuff i think), have some silicone adhesive left over, etc and so it should be a pretty cheap project. Should i put some foam over the Bamboo X in the back for comfort, or with low weight would it be unnecessary?
Anyways, if anyone is interested, i can come up with some sketches of what i'm talking about and upload some pics.
Besides lack of innate rain protection and the possibility of snagging it easily-especially if bushwacking, what are some potential cons to such a pack?
