I understand you taper the deadzone/deadwood area where the keel meets the rudder, so that they are the same thickness once planked, but unsure of the approach to the lowest/sharpest edge of the keel. | ||

Chances are I'll make the call once I'm about half way down the planking, see how confident I'm feeling by then. [ Edited Mon Feb 02 2015, 02:49am ] | ||

As I mentioned previously, I wasn't comfortable with the 1mm of surface area holding the bulwarks against the deck, so I've gone and inserted 3mm sections of balsa under the deck and behind the bulwarks. MUCH sturdier now. Could vault a gymnast off them now. And also wasn't happy with the thickness of the bulwarks at only 0.8mm thick. So I've started laying 0.5mm planks over it, which I'll eventually putty and sand smooth. Can see the light at the end of the very dull (but very important, as I keep telling myself ;P) preparation stage. If all goes to plan, I should be planking before the end of the week. | ||

Good bit of practice tapering and cutting inserts ahead of doing the hull planks. These are 0.5mm limewood planks, so with a good sand and fill, they should be nice and smooth. Bit of fancy scalpel work getting the holes cut out near the bow.     | ||

| Registered Member #4549 Joined: Tue Dec 30 2014, 04:23pmPosts: 59 | I have a question regarding the hull planking given this ship has a slightly curved bulwark/hull line (i.e. the deck line curves up slightly at the bow and stern). When I lay a full length hull plank up against the bulwark, it's pretty clear one long plank isn't going to do the best job in contouring to both the bulkheads and run snug along the bulwark. Is it advisable to run shorter lengths of hull planking instead of one long one? If so where am I best having each shorter length meet? I assume have them meet in the centre of a bulkhead. Any wisdom is appreciated. EDIT: Worth noting this is a double planked hull. [ Edited Thu Feb 05 2015, 09:33am ] | ||

These include submerging it in hot (near boiling) water for 5 minutes and clamping it onto the hull; letting dry completely before gluing. Have a look at my log to see how this turned out (called first project: billing boats Bluenose). Peter | ||

It's really a case of needing to get some curve on both axes of the plank: it twists to follow the contour of the bulkheads, but also needs to bend along it's thin edge to map to the deck line. Did you encounter any problems in soaking the planks? Off the top of my head my first layer planks are 2mm limewood, so they're fairly rigid along the thin edge. I'd imagine the wood swells when wet, so you'd need to wait until they were completely dry and contracted before gluing? | ||
