To this point in my project the things I would do differently is :
#1. Take notes to where I left off when it was going to be awhile getting back to it.
#2. Start out with the carport tent from day 1.
#3. Order all the plywood at one time being i had to have it delivered across the state.
#4. Never use Doug-Fir for any trim pieces that need to be sanded. When it was all said and done,I might have saved $50
over using honduras mahogany and the way the mahogany works with hand tools is well worth it.
#5. To not stare at it more than i actually worked on it :)
I built this boat in work like fashion. Like I was making a living at it. Didnt manicure anything. I measured
twice and cut once but attacked it nonetheless. Every day was a goal and I tried to stick to it. Next one will
take more time but I really didnt suffer through any of it. Think if I was to do this again, would try butting the planks
in place. Trying to have a flat enough surface to do the glueups was more work than if I had done it on the boat.Plus you
can't see one side of the joint until it is cured and you flip it over. The bottom planks were done in place while they
were being installed.This was much easier to control especially using the biscuits. Also made my own biscuits out of mahogany
with the grain going the same direction as the top ply in the sheathing. Also found I could use the biscuit jointer to
cut a full witdh dado for a blind spline if I wanted to. In thicker plywood you could adjust the depth to make a wider dado
for a thicker spline. It does this exceptionally well. Just plunge it and hold it in and let it go as it will ,moving
it slowly along the butt. Makes a very clean dado. Also considered toungue and grooving the butts also with the same tool.
Didn't see the need tho. Will try a test piece to see how strong it is or isn't. If I did it this way,would leave a slight
gap for thickened epoxy. Mechanical/composite butt joint. I think this can be done with 7 ply 3/8" but wouldn't try it on
the 4 ply . Would still use the glass tape as Dave suggests. Remember,with the butt joints staggered,they will have a full
run of the plank below and above across the joint where they lap. It would be hard to break no matter how you do it.
