Are you asking me?
I've got a 16' long straight metal straight edge that is screwed to a 16' long 1/2 x 8 inch wide laminated piece of plywood. I have a saddle that holds my circle saw so it will travel down the straight edge without any deviation side to side, and the blade skims the edge of the plywood.
I position the edge of the plywood where I want to rip and make the cut.
I found this method is so much easier and requires less room than trying to straight line rip on a table saw.
I think I've got pictures someplace in the postings of my ripping jig.
