Also, I should say that the wheel set is welded on the frame, and there's really no way for me to move it anywhere. I could take the whole thing apart and put it back together such that the wheel settles in the middle, but that requires me to slice through the aluminum tubing with a hacksaw, and a lot more drilling....
another thing I gotta worry about is the joints by which the tubings are connected. What I did was use a thinner piece of CPVC tubing that slides easily into the aluminum, bolt it onto the aluminum, and so the same to the other side. The PVC sections do make complete contact with the aluminum, even though it slides right in. I don't know if this joint would be adequate.
