One drop was giving me intermittent issues, (almost see next post) resolved and memory guide a page or two back updated.
The plunger for the rearmost blue drop target would get hung up time to time due to the plunger not being perfectly pointed "true" (and screw sticking out)
It would rotate I suspect and the point would become off center and work sometimes and others not.
To fix this I made a jig in which you place the plunger (using a nut and washers to space out) hold it up to the belt sander lightly and rotate the plunger till it was perfectly true.
Worked pretty good.
