anyone have any experience refilling / recharging a scope with nitrogen / argon ?
i have a couple of older nice redfield scopes that need some work and rather than send them away to the states and wait and pray i see them back in the next couple years ,i was thinking , how hard could it be to refill them ?
the o rings look good , and on the one it shouldn't be any more than a good cleaning , finding a compatible grease for the o rings then purging the scope with argon or nitrogen . ( i'm leaning toward argon since i have a full bottle of it on the tig welder ) .
think giant sealed plastic bag with a hose running into it ... something like a large heavy ziplock bag or similar ...... maybe duct tape some rubber gloves to the sides to assemble the scope
what i'm wondering is , are scopes normally pressurized with a inert gas ,lets say 5 to 10 psi for arguments sake ....... or just mildly pressurized , less than 1 psi ? or hell even placed under a vacuum after purging ???
really what is the worst that can happen ? i waste 20.00 in gas and a few hours of time ?
btw any idea on what to use for grease for the o rings ...... would it be just as simple as vasoline , or maybe something made for a refrigeration system ....... then again argon is a inert gas , so would it even matter ?
