WP lips,You could copy your buddies buzz saw, what would help for slabs is a longer than usual swinging table to support the long slabs.The long table would keep you from having to hold the slabs down with less tendency to bind.Most old mills used a jump or swing saw to cut slab where the saw moves not the slab.A buzz saw is a crosscut saw so the angle of the cutting edge should pass through the arbor hole.Any hook and they tend to grab, negitive hook and their harder to push into the wood.Frank C.
