I had planned on using sawhorses for the base. I tried it and didn't like it. Even though I bought nice metal sawhorses, they didn't seem stable enough for me. Then there is the garage floor slope. It work out to be just under 1inch slope over 8 feet. That would have meant rigging something with the sawhorses.
So I decided to build my own base. 4x4 post at the 4 corners. On the uphill end the post are 3 feet, and a bit longer on the down hill side. 1x4s for a frame for the top and shelf area, and middle support
The bottom of the top is 1/2 inch MDF. I am using unistrut glued to that. Then I will put a 3/4 inch top on that and bolt it all together using carriage bolts.
