Hello I am building my first* ship, the Lady Nelson. There is this stop-motion video on youtube that shows the planking, and when they measure for the 10th bulkhead they only measure the bulkhead itself and not the space that goes from the bulkhead to the keel. Surely the measurement needs to go to the keel? A few frames later in the video he has his chart showing how to taper each plank. If I were to taper all the planks based on this then there would be no planking between bulkhead 10 and the keel...? A couple other questions: * Is it correct that when you taper you always taper the top of the plank so that the bottom of the unbent plank remains a straight line? * When you bevel/chamfer a plank so it will fit better against the next plank, is it best to chamfer the bottom of the plank? * Am I better off in the beginning to cut each plank individually, alternating between starboard and port? Or should I try cutting them in batches? I tried using magnetic jaws on my bench vice but they aren't strong enough to be stable when I clamp down on the planks. I've ordered the amati plank/hull holder thing but I don't expect to receive that for a few weeks - so for now I'm tapering with a straight edge and hobby knife. * Is there a way to unglue something? There are two pieces at the stern that I somehow glued on crooked and after reviewing the plans they are supposed to be parallel with each other. I glued them with both CA and PVA. I was thinking of possibly just cutting them off and fabricating new pieces on the scroll saw. Thank you so much - I apologize if these are FAQs. I've tried searching but am a bit overwhelmed and not even sure what the correct terminology is that would help in my search.
