Use Clamp-On Edge Guide for Straight-Edge Rip Cuts
I tried several methods for ripping rough-edged boards on my tablesaw with mixed success. Then, while I was using a clamp-on aluminum edge guide and my circular saw to cut up some plywood, it occurred to me that the answer to my ripping dilemma was actually right in front of me.
Now, to rip a straight edge on a board, I first clamp the edge guide to the workpiece so it overhangs the edge of the board slightly. With the edge guide lined up firmly against the tablesaw fence, I get straight-edged rips every time.
By the way, I have a 48"-long Tru-Grip Clamp'n Tool Guide, available through many woodworking catalog companies. The guide also comes in 24" and 36" lengths.
