Cart For Mabef Giant Easel Part IV

Here is a "semi-exploded" diagram of such a handcart. I did write 39" but it is really 40" long. I am thinking of building it out of wood.

I do not, however, have a drill press. So I am unable to drill holes at the end of a 15"x 1/2" axle shaft to attach cotter pins. I could always order a custom length axle shaft from one of those internet companies. But the prices are outrageous.

Some of you might ask, well why not buy the type of bike cart designed for walking too? For example, Wike's "Speedy Cart"? This foldable, lightweight cart is as good as the Burley Travoy but much better priced ($99 vs $269). Unfortunately neither the Speedy Cart nor Wike's Golf Cart is narrow and long enough to hold the Mabef Giant easel securely without major bungee intervention.
