No problem. Happy to help. The first regulator (1/4" one) really isn't needed if the air compressor being used to fill the tank has an output regulator. As for the second regulator (1/2" one), I wanted to use this so I could set the PSI output of each blast.
I had mine on a remote control(and hidden) so I could control who got blasted and who didnt( like very little kids cuz its loud) so Id nail the teens and the Parents.Loads of laughs,great prop.
Nice work,you'll love it.
The flange came with the 1/2" regulator and I will be attaching it to something as the cannon is a little top heavy and tends to want to roll over. I currently have just a homemade push button trigger (shown in picture above) to trigger it, but may connect it to a prop controller. As for the first regulator(1/4"), I know it's kinda over kill but I had it sitting around so figured why not.
