TL;DR I want to make a high capacity trailer from bamboo to ride around at a desert festival.
- Bamboo structure (probably 1.5" or 2" major strength lengths, 1" for crosses)
- Hitch using bamboo & bamboo joints to get it up to a rack or seat post, with one of the varied DIY hitches seen around the internet.
- simple wheels with high rated weight capacity, or dual wheels
- simple steel length with clamps on each side of the wheel to mount,
- similar clamps to mount to the bamboo
- weight capacity will be 300+ pounds
- Estimated costs (at the moment) $200-$250 just for the trailer structure & seat location, and budgeting for mistakes)
I'm seriously considering a heavy duty bike trailer for this year at Burning Man (those who don't know, giant arts/community festival in the middle of the desert, so very flat). I'm planning on having a large capacity 36v battery pack as I'm going to get an electric front-wheel conversion kit, and I want plenty of power (plus for lighting & such). So if I go for 20 Ah pack, that's something like 40+ pounds. Then on the trailer a small-ish disco ball suspended off the back with lights for at night. And another 12v battery for all the lights. And a small lockable storage space for stuff. And then a seat for someone on it. So, all told, plan on 300 pound capacity.
Searching around the net (both here and elsewhere), I think I've settled on bamboo framing & structure for it's strength, lightweight, and easy to work with (no welding!).
The two things I'm uncertain of right now, are the hitch & wheels & wheel mounts.
Hitch, I can do something fairly simple to attach it to a rear rack or even seat post.
Wheels and wheel mount is more complicated. I've seen quite a few people have success with 20" BMX style wheels but I'm trying to keep costs somewhat down. Or maybe something like plastic 20" wheels or 24" MTB wheels from Northern tool. As an alternative, use a much lower rated wheel in 16 or 20 inch, but go dually, so 2 wheels on each side. For mounting, seems like I could even just get a length of steel from Home Depot in the right OD, cut it to length, and put some clamp thingies onto it to mount the wheel (which includes bearings) and drill a hole in the bamboo and do the same to hold it in place.
It's very flat terrain with semi-formed dirt roads, not going to be going very fast (maybe 10mph) does what I've said above seem doable?
