Since we're drifting already anyway... the next level of hell is trying to remove the rudder from a Grob Twin Astir that's been stored outside. Cursing in 6 languages, ruptured blood vessels, gallons of penetrating oil, and entreaties to various deities didn't do it. All I remember is that we eventually ended custom-manufacturing what amounts to a bearing puller. Luckily, we have the world's best machinist in the club.
