Default Quick Attach Dump Box

This winters project is a dump box much like the one shown below, and putting a new 400 engine in my 1979 F350. I may start a thread for the engine build as I might want some help with that. You fellows can feel free to offer any ideas on this dump box too. I will admit that this is an experiment to some degree. For the most part however the design work is already done and the materials were ordered yesterday.

My design is a bit different than the one shown. It is more like a dump box found on a truck than a debris hopper. I plan to use it mainly for soil. I have some 400 yards of clay soil that needs to be moved about 150 yards. I am curious to see how this will handle concrete as well.

Making the swivel caster is the start of this project. I had planed to machine the 3/4" thick swivel plates first but I soon discovered the steel I bought was too hard. I did not specify what type to my supplier, I simply didn't consider the possibility that he would sell me something like this without telling me.

Here is the drawing of the swivel plate assembly. The plan view is on top, the section view on the bottom. I still need to determine how many 1/2" diameter balls I am going to need.

Picture is upside down.

This is a view of the fork. It will be made from 3/8" HR plate.

Hahaha I don't think it will work. The assembly I am making will weigh almost as much as as a brush hog.

Nice fabrication. 1/4-28 is a common size for grease zero too.

Three points I would advise when clamping down the work in this manner.

1:Remove all chips from the mating surface. They can reduce the friction and allow the workpiece to move.
2: When possible place the workpiece in contact with the stationary jaw of the vise.
3: Place the contact point of the clamp as close to the blade as possible. This will reduce the mechanical advantage the blade has to move the work.

Two welded areas remain that are holding the parts in alignment. They will be removed after finish trimming on the belt sander.
