I had my blades jump too, until I learned where to set the jib for the start of the cut. Once I had the pivot point two tenths of a gnat’s butt in front of the blade, the problem went away. I then glued a stop block on the underside of the circle jig so I could run the wood into the blade and, once I hit the stop, start spinning.

In the time it took the guy with the table saw to trim his wood near that scary blade, I can cut five of the circles he did (time to position it on the pivot pin not counted).
