Using 1" Camlock for quick release element?

Thank you Bobby M. That was what I was worried about. So you would have to have a 1.5" Camlock pair and a 1.5" to 1" bushing to make this work.

Well, I'd lean towards drilling and tapping out a 1.5" Dust Cap just due to cost and simplicity. I'd also only go after this if you're able to solder or weld a bare bones Male cam QD to your vessel. Making 1.5" NPT weldless would be a major PIA.
