Used it today and thought I’d share this simple 18 x 48“ (4 x 4s and 2 x 4s) scrap wood jig for freehand cutting log lengths with a chainsaw. Adjustable width for supporting small to big log lengths. Works great for supporting ripping cuts to remove the pith. Use the free boards as sacrificial or to wedge odd shapes between the rails. No need to lift heavy logs, drop them from the hand truck onto the rails and slide into position.
