| here is the straightedge lined up on the blade |
Table saw tune ups are necessary and annoying. And for me, I've never really gotten my table saw "perfectly" tuned. I've always had the nagging suspicion that using the blade as a reference was insufficient: with a 10" table saw blade, the distance between the reference teeth is a mere 5" or so. That's not a lot of distance to magnify any deviation from square.
But this week I had a bright idea: I used my machinist's straightedge to lengthen the reference surface to a whopping 24". By laying the bar flat on the table and resting one edge against two opposing teeth on the blade, I essentially increased my precision roughly 5-fold.
