I dropped a lathe (Denford Viceroy) in the canal a few years ago. I was selling it to the guy at the neighbouring boatyard. The trailer 'became unhitched' just as I was setting off to deliver it. After 3 days underwater (it was quite a game salvaging lathe & trailer from 6' of water with no lifting gear!), I dried it all out, changed the oils, put the motor by the stove in the kitchen for a few days. He still bought it for the agreed price, knowing what had happened, & sold it earlier this year for more than he paid me for it.
