Update: All the parts are present now, I just need to decide if I want to stain all the laser cut burnt edges black to get a more even look or not?
Pendulum Update: I went all the way up to a 13 inch long balsa pendulum and got a 4 minute run time! Well the run time was nice but the action was not smooth, you could see each individual "tick" on the pump arm, the pump was basicly stopping and starting every time the Pendulum changed directions.
Photo: the complete pump jack, the Pendulum in the photo is my best performing one so far, you can see 2 Woodcock feathers taped to the Pendulum base, I get just under 2 minutes run time on this Setup, the feathers are light and small so this is longer than stock pendulum but the wind resistance seems to REALLY smooth out the action. I probably will not mess with the rubber power much more and see what I can come up with for a flywheel pulley to drive it now.
