I am the end of the world

Preliminary grind box dimensions. 2 ft. tall by 4 ft. wide by 16 ft. long. The plan is to have a metal top and sides with angle iron coping. I plan to have a handle on one end and flip out casters on the other for transportability. I will have some drawings up this week and plan to start on the box this weekend. Hopefully this thing will be legit!
