In a shop, it's polite to wait until someone finishes a difficult glue up or stops playing with the sharp spinny thing before you interrupt. So I was grateful that the weather showed the same good manners.
I had just finished gluing up the port side (I refer to port and starboard as if I were sitting upside down in the boat, since it is currently upside down. This seems more correct. For absolute Clarity the port side is the side facing out into the garden in the photos) anyhow, as I was saying, I had just glued up the Sheer Clamp, all held in place with waxed deck screws and large washers. I was crouched in the gap between the bushes and the boat, just about to start drilling the holes for the starboard side when I felt a few drops of rain, then a few more, and like Cockroaches and Politicians, where there are one or two, there are always many many more.
Tarpaulin up, tools away and back inside for a hot shower. All the while thanking the polite rain for not disturbing me halfway through the port side, and for not letting me get well started on the starboard.
Incidentally, one very handy tool for boat back garden building is a Garden Kneeling Pad. Basically a piece of durable foam with a built in handle that's just right for kneeling on. Kneel in the cold wet mud, or hard concrete for a while and trimming those last two notches is a whole lot less fun. Get one for feck all + postage on ebay.
