After the instant destruction of what looked like a decent repair job on the fractured bottom plank of my new Bee, construction paused for the weather to warm to more epoxy-friendly temperatures. On Tuesday, the break was repaired again. Today, the seams were re-stitched with plastic ties and the bow carefully tightened...and tightened...and CRACK! the other bottom plank split.
After a suitable period of self-examination and meditation, I came to the conclusion that I was doing it all wrong. I screwed the bottom planks into the moulds and then forced the bow section up into position, threading the plastic ties through as the gap closed. As a result, brutal stresses build up in the wood.
On re-reading the instructions, I should be sewing the bottom edges of the planks together loosely, placing the pair into the moulds, and parting them so they come to rest in position. This process will, I suppose, allow the bow to adopt its natural shape and avoid critical stresses.
So I have completely undone the boat and will cut two new bow pieces out just as soon as I can locate my jigsaw in the pile of garbage in my shed.
