A 1/4 scale RC model perhaps?

The forks are in place. The two 1" diameter rods connecting the forks are for locating only, once it is all welded they will be removed. The attached C clamps are for counterbalance.

I have a gusset in place but I'm not quite happy with it. I am still trying to integrate the fender/shield and provide enough structure to carry the load. This gusset is not getting me there. I have some other ideas, in time one of them will prevail.

It is a bit confusing to see (especially if upside down) the frame of the dump box. The frame is supported by a fabricating jig that has been leveled, various bits and pieces are resting on top of it.

At this point I am developing on the go as I have no drawing of the gussets or fender. Here is what I came up with.

The pieces are tack welded together. The twine that is protecting the bearings from weld spatter will be replaced with copper wire as I don't think it will hold up to the heat of welding.

It's a beast. I don't think I can bend it if I tried. The four stiffeners placed on the forks are 1/2"x2", they made a huge difference in my confidence. I guess it weighs 150 lbs. at this point.

I am now more concerned with the durability of the swivel assembly. Remember the bearing races are not hardened. I spent a fair amount of time designing it, I don't know what else I could do short of making it larger. There is nothing I can do about it now. Moreover I don't really know if the caster will track properly or if this entire approach to dumping will even work. We shall see.
