You can make a basic table from a 4x8 sheet of plywood or mdf with your X axis travelling across the 8’ direction however wide that is, giving you about 3’ on your Y axis.
That’s what I’ve done here: New Build in Southern Oregon - #14 by dhiltonp
Then you can do tiling cuts, cutting sheet goods in sections. I’ll have to do that to cut my strut plates. The basic idea is you add a couple of holes every 3’ (because that’s how much Y travel you have).
On the first cut you also cut 4 holes in a square in the corners of your piece, to move the board you align 2 holes in the top with the other 2 holes in your spoil board with pins, on subsequent cuts you only cut 2 holes where the pins aren’t.
