Has anyone out there attempted to make the automatic coolant applicator by Glenn Wilson in the december 1999 issue of Machinist Workhop.I got the electronics working ok, and I can here the piston working up and down. All I get so far is a steady gravity drip. What can be expected at the fluid end when the piston is in it's down stroke. Will you get just a drip , a spurt or what? Is the small O ring necessary if you dont mind the gravity drip ?
