When I was building the Garage Cabinet (which I am still happy with), I realized I needed a method to cut down large stock like plywood without using the bed of my pickup.
The plan was to build two sawhorses that could come apart for storage and portability along with a wood grid that could hold a 4’x8′ sheet of plywood while it was being cut with a circular saw.
In the cabinet build I came across a deal at Home Depot where a sheet of 3/4″ A/C plywood was $24. How can you pass that up? I picked up another sheet- which is all I would need for this project.
What is A/C plywood? One side is rated “A” grade which is the top grade without knots or defects while the other side is “C” grade which will have knots and filled in defects. This is for sawhorses- any grade would be fine but these sheets are solid and straight and cheep- so that is what I used.
I didn’t do much in the way of plans this time. I am using the two detailed diagrams from the Wood Working Tips side linked above.
Then it is time for some assembly. Gorilla glue and 1 1/4″ screws all around. You will note that there is a vertical piece of scrap at the top. That is a spacer to ensure the stretcher will fit later on.
After I had an interview this morning, (it went very well, thank you for asking) I got cracking on the grid. The grid consists of two 8′ long rails, two 4′ long stretchers and the two saw horse stretchers made earlier. They will fit together with notches creating half-lap joints.
This grid is sturdy and large enough to hold basically any plywood or normal stock that I would come across. Given a sheet of plywood, this could also work as the frame for a portable workbench as well.
It fully collapses and can get pushed right up on the wall of my garage. I will probably figure out some way to hang it off the floor as well- but not today. Today I take a drink of cool water and enjoy my handy work. Then I get the broom and clean up…
