Seems a lot of folks have searched (unsuccessfully) high and low for no-longer- available rubber "plugs" to rejuvinate otherwise sound Groco SV series seacocks. I'd like to try molding new plugs but need some to use as patterns or measure to make molds since mine are all currently busy keeping the sea out of my
boat
Does anyone have some old Groco SV series seacocks laying around they'd be willing to sell (or better, donate to the effort)? I'm specifically looking for 3/4" and 1-1/2", but would give any of them go to develop the process. After I machine molds, narrow the right compounds to use and solve adhesion challenges/technique to bond to the handles... yeah, for the time and effort, I certainly could replace with all new ball valve seacocks, but I like a challenge and keeping old stuff going. I'd likely consider this an "open source project" and share my method (if successful)
Thanks kindly,
