good if not it is something other than 90 deg.
I'm liking this idea, since I'm going through a period of not trusting any of my squares to be really square. I want to get the saw as close to dead perfection as I can, just for the goofy thrill of it.
So the indicator is rigged up so that the base smacks butt up against the blade I guess. That seems the only way to ensure keeping the distance from the indicator to the blade the same. The problem I'm seeing with that idea is that it would have to straddle the insert more on one side than the other. My insert isn't perfectly flat, and not perfectly parallel to the table surface. The best I could do was settle for not having it stick up anywhere. So that would throw the measurement out of whack, it seems.
