OK, here's how NOT to do it. Remove entire valve core, its big enough to put
air blow gun right down barrel with room to spare. Tape up air gun and valve
stem so they are tight against a 3/4 sweat Tee. Clamp hose onto other side
of Tee and go to a barrel. Apply air. Works great, until tire blows out in
your face.

Pump into a 55 gal drum and reverse when done with your repair. I saw a
set of 8N sized tires on Minneapolis Craigslist last week. Have fun!
