Ah shitballs !!
My Vacuum pump is only doing -0.75 bar right now......that ain't good enough.
The vacuum thang is very important in this experiment.The terminal velocity of a ping pong ball is really slow.Low mass , high drag.......The only way it'll go 500 mph is in a vacuum....
The vacuum pump is going in for service monday , but really it's not good enough......it's right on the cusp.......The first shot I did that worked was -0.82 bar.For this to work properly you really want -0.99 bar.
I'm messing aroung with making ABS c-d nozzles.
