Thanks guys, anyone have some pics easily accessible of the rod seal end? I'm working on that today, had to make a internal grooving bit. I assume you want the rod hole to be as tight as possible? Of course some clearance. I have x-ring seals, o-ring seals and actual 1/4" seals. The 1/4" seals have an id of 1/4 and a od of 1/2". No way am I getting that seal into a 1/4" hole for an internal groove. I'm thinking of making a wider portion of the cylinder with basically a washer, with a standoff for the inlet port. So the piston doesn't top out past the inlet port. Then a plug cap bolted on. That way I could use the better seal and just push it in. The plug cap would also get a wiper and oring on the outside for like I guess a gland seal? Not sure if that is right. All sounds complicated but is pretty simple and will be easiest to install.
