A Pictorial Review

Our Humble Laboratory

Curvy Bits: Nailers and Bulkhead Beams


Cheat Sheet... note bevel angles drawn along sides


Deadflat Plates ready to turn and join upright...
After the first one, they are flipped onto loose copper plates which are then
nudged into position and fastened in place.

End Sections... note transverse kerfs to ease bending.
We'll flip 'em, join 'em to the Deadflat and later add their 2nd course of
planking, underlayment and copper.

Lower S'brd Wall and first Bulkheads standing.

End piece about to get joined

All of our projects seem to attract a 'Ship's Cat'!

Three stages of retro-fit SIP (from left to right):
I'm adding the inboard layer of 1/4inch ply,
Middle layer of 2x XPS foam (blueboard),
Inboard face of 1/2in hull, with 2x framing.


As of yesterday... both walls on, Whiskey Plank in sight.
Note Port Wall before Doubler Plates...
1ft lower course visible below upper, 4ft course.
3/4in Doubler Plates (visible aft) provide protection
and act as a Butt Strap, joining the two courses.

    Hello Dave and Anke,

    Vicareously exciting to see the photos of your "bacht" (barge-yacht, or is it a yarge?) under construction. What a beautiful view you have out the front door of your work shop! Do I recall that you planned to install the copper hull plating as you built the hull? Would enjoy seeing photos of that process if you post more construction blogs. Lots of questions come to mind, but I counsel myself to be patient. I'm sure you will post more info as time becomes available.

    Thanks for sharing,
    John

  2. Hi John,

    Thanks for the good wishes! And yes, the view is gorgeous! Right now, the first snows are creeping down the peaks.

    Love the bacht / yarge terms... 'yarge' in particular feels right, though our (engineless) type might be called a 'row-bacht'. 8) Gordon Bok had a great cartoon of a tug-boat pulling a barge laden with odd-ball equipment, and captioned it 'harboring a grudge'. Tickles me pink.

    We have been coppering as we go, though the pics don't show much. In a previous post, we were thinking of building the deadflat in sections, coppered before turning. Chickened out and instead did the following.

    Started with one 'reference plate' attached before turning (visible in the pic, this post. Turned it. Butt a loose plate of copper to the reference and attach from underneath (bronze #6x1in screws). Flip the next section. Repeat.

    It was an easy matter to jack the deadflat as it grew, and slide the next copper plates under. By doing it this way, we were assured of a tight fit without chance of measurement errors. So long as the reference sheet is attached square, the rest follows. If a little mis-alignment creeps in, keep the but tight, but adjust the cross position at each sheet. Any error is covered by angle 'iron' (bronze).

    We left the outboard edges unattached, allowing it to flop a bit. Once the sides get their underlayment coating, we'll run a band of it along the chines, overlapping sides and bottom for a contiguous, (hopefully) waterproof layer. The 'flopped' copper allows us room to insert that band. When all is complete, finish fastening, angle and done.

    More pics as we reach that stage.
