The Bulkhead Curve
By Nick Champion
I started my Weekender in January 2000, with the full
expectation that I might be in the water by the 4th of July. HA! It hasn't been cold
weather or family obligations which slowed me down. It has been the insufferable Louisiana
heat, my own inertia and a few mistakes which have held up the show.
When I went 3D (about early April) I discovered that the
cabin bulkhead didn't land in the designated place described in the plans. The floor
stringer it was supposed to anchor onto put the bulkhead at an absurdly low pitch. Also,
the measurement from the bulkhead to the transom was off by about inches. I went back to
the plans, trying to figure out how the Stevenson's got it so wrong. For the moment, I
decided that the measurement was supposed to be taken from the front of the floor panel
joiner instead of the rear. That seemed to account for most of the discrepancy, but
still...
I decided to tackle some of the other small jobs to keep the
project moving while I pondered solution. I cut out and fabricated the ship's wheel,
rudder, bow chocks and several other pieces, but I was stuck on the cabin bulkhead
placement. I laid out a possible remedy, dry fitting a 4+ inch spacer shim to the forward
edge of the floor/bulkhead stringer. This put the bulkhead at an acceptable angle, but the
cabin was that much smaller and the cockpit that much larger. However inelegant, this
seemed to be a solution I would have to live with. Then in a rare moment of insight and
clarity, I realized that I had misread the plans. When lofting the deck panels, I had
placed the bulkhead curve 9 inches aft of station 10 instead of 9 inches forward of
station 11. This accounts for the misplaced bulkhead. Now what to do? On at least four
occasions, I decided to move ahead with my spacer remedy, but each time I vacillated when
I looked at the front step I was going to leave in the cockpit. It was something I would
see each time I boarded or looked at or even thought about my Weekender.
This became a bottleneck. I couldn't proceed with the sides until
I committed to the placement of the cabin bulkhead. Since I had discovered the error of
the deck curve placement, I toyed with the idea of somehow moving this curve 5 inched to
the rear. I played with this idea, weighing the feasibility of a curve replacement v. the
front step idea and decided to try moving the curve.
Once I decided to try this, it all fell into place. I copied the
curve onto a piece of 3/8 ply, repeating the curve five inches aft on the same piece of
wood. I cut out and dry fitted this in place, and sistered this small piece onto a longer
piece of 3/8 to glue and screw in place. I back filled the seam with thickened epoxy and
PRESTO: it worked! I repeated the process for the other side and I had a solution, which
brought me back to specs.
The lesson I learned is this: don't get hung up on small
mistakes. I think I would have been OK with my makeshift remedy, but I wasted a lot of
time fretting and worrying about it. The actual solution took less than two hours to
employ, but almost two months to think about. I'm glad I took the time to finally get it
right, but now my launch date will be in the late fall instead of summer. That is if I
don't get hung up on any more Stevenson mistakes.
