This is something I built several years back that has proven to be indispensable for me. I regularly use sheet goods; 4×8 sheets of cabinet grade plywood, 5×5 sheets of Baltic Birch Plywood, hardboard, etc. Breaking these down on a table saw, alone, is a challenge and somewhat dangerous. Using a track saw means setting up for that requiring a fair amount of floor space, and of course a decent track saw setup. The option I have built here has practically a ZERO footprint, yields solid 90deg cuts and is very easy to handle by myself.
Now, I saw this design in some woodworking mag that I no longer recall. So I can’t give the appropriate attribution here. But the construction was dead simple. Uses plywood for the back, 2×4s for the guide rails and 1×4 stock for several supports and braces. The carriage was made from MDF. The only tricky part involved the circular saw carriage. This carriage is simply a square sled with a long tenon on each side. This tenon rides in a grove in the runners. The recess that takes the saw must be custom fit for your particular saw. Each guide rail is simply a 2/4 with a rabbet cut on one edge. Then on that same edge the face of 1×4 is attached, yielding a grove in which the rabbet on the carriage rides.
The important part of the construction is getting the runners aligned correctly with the support ledge on which the stock sits. Getting this right then yields a nice, square cut down the stock.
Lastly as depicted in one of the pics, I put a support on the wall about 4 feet from the panel saw. This is to support a sheet when you are cutting close to one end, and thus scooting the stock as far to one side as possible.
And when its idle I can store one or more sheets in it, depending on thickness.
