Decided to mod some other stuff... Cuz why not?
As some may know, I've been trying to make my canopy roller bag a little more beach friendly. Removed the tiny 2" rollers, and added a 1/2" axle with some 6" lawnmower wheels from HF. Didn't work very well, they dug in with their 1.5" width and made no difference (possibly worse).
Later, added a longer axle, and another set of wheels, making it a duelly setup. Slightly more inconvenient getting it into the truck, but essentially didn't make much difference in the sand.
Had been looking into balloon tires, but they are pretty expensive, so I went with a plan B. Figured I'd get some inner tubes, mount them to the rims of the wheels I already have, and make my own balloon tires. Easy right? They are 6" wheels, with 4" rims. So I cut the rubber off, and had a nice rim with a channel for the tubes.
There are some 10" inner tubes at HF and the specs say they fit 4" rims, so that's perfect. Picked up a pair, and even after being inflated, they weren't even close to fitting, by a good half inch all the way around. Looking at the rubber tire cross section, there was a hollow channel down the center. So cut the center surface facing section out, basically leaving a channel with a larger diameter that could actually hold the inner tubes.
Cut some pvc spacers to keep the wheels out wide away from rubbing the bag, and pumped some air into them. As expected from a HF product, one of the tubes didn't inflate evenly, and is bulged on one side compared to the other. But under the weight of the canopy, the tubes didn't compress much if at all, so I'll have to air them down a lil bit when it comes time to give them a real test.
