Just a mini post today. I took 1/2 an hour and glued up the scarphs I cut last week. I checked with folks on the woodenboat forum because I wasn't quite sure how to do this. Two reasons:
- My scarphs weren't perfect and there was about a 0.5mm gap
- I was worried because of cautions I'd read RE wood sucking all the epoxy out of a scarph joint into the end grain and ruining the joint's strength.
For gluing I use WEST system with the slow-curing hardener and WEST adhesive filler fibres. The slow hardener is great because it leaves lots of time for messing around if you don't entirely know what you're doing...like me! Slow hardener apparently gives marginally better strength than the fast hardeners too, but It probably doesn't make a heck of a lot of difference here - I'm more concerned with a long pot life.

I also did the top 2 boards of the transom. I hadn't planned on doing this right away, but I had a bunch of epoxy left over and the stuff is too damn expensive to waste!
