A note on tools: I am using a 3' longboard. Not being the inventive type, on my last project I spent the cash for the fiberglass\foam boards made by 3M (I have both the flexible and the rigid ones) with the Hookit sandpaper-stick system. The 3M-brand paper is a bit expensive, but lasts a long time. The 36-grit with the rigid board worked especially well on smoothing down the deck high spots.
After being satisfied with the deck fairing, next up was rounding over the deck edges. I chose to form a 1 1/2" radius (see my last post for a picture of the PVC pipe I used to make a sanding tool) on the edges; partly this was to avoid taking off too much material, partly because I'm lazy. However now that I'm all done with this part of the job, I think that the floats might look even better with the 2" radius that Ian allows for. Hand-sanding cured putty edges is not much fun though, so I'm stopping here.
Here is a picture of the starboard float edge getting rounded over, in the fwd beam bulkhead area:
See the gap there between the planks and the deck? This particular float half is the one where I made the mistake of trimming the planks too short at the top. On both floats I had small gaps in many places between the deck and planks. I had decided to finish rounding over the edges before filling those gaps:
(The port float in the background has already had its deck-to-plank gaps filled, and is nearly ready for laminate.) Here's a closeup of the putty on top of the bow cap:
(It's hard to tell in the above pictures, but I ended the 1 1/2" radius about 8-10" back from the bow cap front. From that point forward I hand-formed a decreasing-radius edge up to the bow cap. I thought the full radius would be too much if carried all the way up.)
Here's a picture of the transoms, all sanded down:
The weather has finally been warming up - go-go gadget-summer! Today was great, got up close to 70 deg F. I have noticed that the warmer it gets, the more my boat tent begins to feel sauna-like. (Notice in the picture above that I've opened the back flap for more ventilation.) But I'm not going to complain too much after suffering through the winter dorking around with heat lamps and such. I'm looking forward to laminating a part and having it cured in the same day.
