Nutshell Pram EXCUSE ME Daggerboard Trunk

30 Apr 22:

 We started looking at plans for the daggerboard trunk and daggerboard, and noticed that the plans called for the daggerboard to be made out of 2 layers of 1/4 inch plywood. My brain remembered that we had daggerboards from early Alcort Sunfish that were close in size to the Pram daggerboard, but they are 3/4 inches thick. So I checked with Maynard, one of the design team for the Pram, to see if an ich here or there would matter, and he said it would be fine.

We used the new daggerboard to make sure we made the trunk wide enough front to back, the Sunfish daggerboard is 9 inches vs the design 8 inches, The Sunfish daggerboard is also 31 inches vs 28 a little extra daggerboard will be fine and it still will fit behind the aft seat when not in use.

Cut out the trunk sides with a circular saw.

Used the daggerboard to set the width for the trunk end posts, plus 1/8th inch.

We cut a small bevel on the top of the trunk bed logs, to help shed water to the bilge.

Mahogany is dusty, be sure to use PPE.

While the saw was out we cut slats out of teak, to be used for the seats. 

Calibrated seat slat width gauge, 1/4 inch.

Coated the inside of the trunk with THIXO. It will also get a coat of paint.
