Cart for Mabef Giant Easel Part III

After I decided that a handcart, and not a wagon, was what I needed, the question became what shape, and how deep. I took the measurements you see here and discovered that when I placed the chair on top of the easel, the total height is a bit more than 5 inches. And the width of the two arranged in this way is 12".

I reasoned that the cart would need to be about six inches deep for the chair not to fall off the handcart, and about 13 inches wide to give the chair a little play. The entire box would have to be 40" long.

For that box to become a handcart, I would need to add a handle. I already have a recycled steel handle that will work well, that I took from a plastic seeder cart.

One more thing: the axle would have to be at least 15" long and 1/2" in diameter. The length worried me because it had "non-standard" written all over it. By this time I had done enough research online to realize I was not going to find a 15" long axle unless I fabricated it myself. I decided it had to be 1/2" in diameter after I realized that no matter what size of the cart wheels I used, these spoked wheels would only accept a 1/2" diameter axle.
