I want to build a cart for carrying camping equipment and supplies as a potential alternative to a backpack. Pulling a cart with the backpack in it should be easier than carrying it on my back, at least for a flat and even surface. Whether the trails I will be traveling are flat and even enough I don't yet know. The cart would need to support a weight of 25 lbs. and be roughly 18" wide by 30" high. I'd attach a strap to it and wrap the strap around my waist. I would attach the pack to the cart with string or a bungee cord.
I was going to build the cart out of schedule 80 PVC pipe and then attach wheels to it, for example https://wheeleez.com/product/wz1-wak-38tt/ (these are bigger and heavier than I want, this is just for illustration). This might be better: https://www.northerntool.com/shop/tools/product_200660524_200660524. Bigger wheels will roll better and will surmount rocks more easily; the tradeoff is the extra weight.
- What would be an ideal PVC pipe diameter?
- What would be an ideal wheel diameter and material?
