To install you don't even need air (if you are bloody-minded and strong).

I regripped a few of my clubs (steel shafts) by:
(1) cutting off the old grip
(2) removing the double sided tape (lucky could peel it off)
(3) little bit of spit in the grip mouth, and work it around a little
(4) work the grip down using a twisting and pushing motion and bracing the clubhead with my feet (sitting)
(5) line it up
(6) let it dry (24h)

Tools used:
exacto-knife

Any problems with this method?
