Default Re: Model Boat Building

Got the side planks glued on today. This is a two plank per side boat, being low of freeboard, like all traditional sharpies, and from a time where wide, flitch sawn boards were available. I did the same thing with the model, but rather than hang two, separate planks, I got out the lower plank (not really called a garboard plank in a vee bottom hull) with the chine edge cut to shape and the upper edge left straight, then glued another straight edge plank to the first, and cut the sheer shape on the upper edge of that. I then was able to install the whole thing like a sheet of plywood. I was careful however, to make the sheer plank a sensible width, and keep both sides the same in case the seam shows up, or I decide to express the seam somehow. The lower plank sweeps up pretty high on the stem and stern post with the two planks nearly equal in width amidship. Im pretty sure this is how the boat would have been planked. The lower plank can be cut from a 12-14 wide board. No sweat in them days. And even now, clear eastern white pine can be found that wide. At any rate, I think the plank seam is visible in some of the pics.

I left the planks a tad wide, rehung them on the boat, and marked them out again, marking also the other edges of the chine, sheer clamps, and stems, so I would know where to put the glue.

I used Titebond for gluing them on, as I wanted enough working time to get everything just right, and the clamps on. I found these little plastic spring clamps at Harbor Freight. Six for $1.99. Bought a bag full of various clamps for $12.00. The ends of the planks are tricky to clamp, just like on full size boats, and the second one is worse than the first. I used sticky back sandpaper on little cauls to grab the planking, and it worked well enough. A better solution would be tapered cauls with sandpaper glued on with Titebond.

This is a milestone of sorts, and I finally think Im making some progress. Bottom planking is next, Chesapeake style. Stay tuned.
