Hey Chip!
1. Automation Direct parts saved us about 1/2 pound. We might swap over to the small regulator too.
2. We used the
pressure gauge. We also used
3/4" x 10" stroke cylinders for our catapult and a
7/16" bore x 2" for our boulder ejection for low goal. The
vent plug works great as well.
3. Will PM address
Thanks again to Automation Direct!
