Or even drilling a random but bigger hole but that would involve removal of the nut, catching all the balls and then feed them back into the nut. I think I'll pass as these nuts do not have removable return tubes. But that doesn't prevent me from boring the thru-hole at least the same size as the bolt hole in the nut flange. So I'll make the flanges on the two used at the nut about 3/8" thick, and plow a groove about a quarter in deep from the inner diameter out to cover the drilled thru holes. The bigger the better as I'd druther not have the air moving thru it at air nozzle violence. The idea just crossed my mind too, to put some sort of a fitting in the end nipples, that would allow a slightly positive air pressure to be established as a further reduction in sucked in dirt. Once what I am thinking is done, I can always spin it with a hand drill so I can see any flow restriction effects from G0 movements. A 1 lb over PSIA internal pressure, if maintainable, would go a long ways toward preventing a vacuum collapse of the bellows being stretched. Enough pressure to make them rigid enough that they won't sag into contact with the screws would be a plus in my mind I have shop air of course but no handy regulators that could do 1 lb reliably. Darn, you get the nuttiest ideas out of me when I let my mind out to play. :) Thanks Andy.
