Hi Al
Am in Alba too,just outside Edinburgh... me an big stu(on here) are buildin our first canoe an all from ply wi plans found online. If your ever in the area a meet up would be cool, would not mind pickin your brains about your canoe a little,(i used to work in a fine art bronze foundry too so may be of use to you with yours) although ours is just the simple flat bottomed one. The workshop i run always has a warm welcome for fellow bushcrafter types, especially if you consider the outdoors as a habitat an not just a holiday.
We also have our own propane forge if you ever fancy a shot.

Chris
P.s Nice trailer, sure i've seen it or ones very similar.
