Bateau Corsair 13 - March 6
Got home just before 9PM and could not resist taking a look at my first butt joints. Here is what they look like:
I noticed some of the epoxy was squished out which is what I had wanted so hopefully the epoxy layer is even and without voids. The panel outside surface is not a smooth as I'd hoped however. Notice also the shreds of the plastic (grocery) bag liner stuck to the joint, now I know to tape them down.
To test the results, I tried lifting the panels at the joints and making them flap to stress the joints - no cracking sounds so I suppose the joints are ok.
These were the bottom panels that I butt jointed one of which looks like this: 
(nearly did not fit the length of my workshop)

I'd suggest using a heat gun with a stiff putty knife to clean up that extra epoxy. Just heat it up good and it will scrape right off. Be sure to avoid breathing the fumes if it gets too hot. It's not real nasty but it will make you caugh for a few days if you breath in too much.
This looks like it's going to be a nice boat. Thirteen feet is a good size.

Thanks Paul for the vote of confidence. Is removing it with a heat gun better than sanding it?
Yes, it's just a lot easier. You won't be able to sand right up to the edge of the butt block but with a heat gun, you'll just cut the epoxy out like it was butter. When you remove the excess with heat, you also spare the wood from sanding and may end up with less fairing to do later. Just don't go craze and burn it or breath in too much epoxy smoke. ;-)
