Are the ring nails copper, like the ones used to reinforce the frame lap joints? I also wonder about perpendicularity of the nailed frames w.r.t. the boat bottom --- maybe you cover this later in this video (I have it paused at 4:16). I further wonder about preventing the frames from being yawed w.r.t. the boat centerline.. Yawed frames would make the strakes non-mirrored on port & starboard, so the boat won't travel straight when it should. Thanks in advance.
Interestingly I've got 2 questions about perpendicular frames and not totally sure what you guys are referring to... the bottom of the frames are square and nailed to the bottom of the dory, I guess bending rocker into the bottom will cant the bow and stern frames ever so slightly towards amidship but this tiny amount of distortion has little to no effect on the shape of the hull... it's not something that is considered a issue in traditional dory building... if I'm miss understanding please try explaining again.
@@danoyes1 There are three axes here: the alongship one (bow to stern) which is the roll axis. The vertical axis (up down) is the yaw axis, and the last one is akin to steering to port or starboard --- that one is the yaw axis. If the frames are installed with a yaw error (non zero), then the planks on one side of the boat will be shaped differently than on the other. After watching the video I realized you aligned the frame thwart with the frame line drawn on the sole planks. My worry is that when driving the first bronze nail up thru the sole plank, is that the frame will walk slightly in yaw. You would really need clamps on both port and starboard sides to prevent this, and even so, vibration from hammering the nails can still move the frame(s). I'm not criticizing your methods, just a newbie making an observation. Sorry I didn't reply sooner & thanks.
@@kenrolt8072 ahhh, OK, yeah I see what you're saying. The clamp is there to keep the frame from falling over fore and aft, I suppose it also does help keeping the frame aligned with the athwart ships line I struck but the key is to get in a couple nails to anchor the frame in place, I double check the alignment before drilling then put the backing block on the frame, there is little resistance nailing through the pine so not alot of vibration to move the frame, once the nail gets into the drilled hole in the oak frame it's Locked in place and not going to vibrate into misalignment... also if the frame moves before nailing you'll know because the ring nails won't drive into undrilled oak.
Good props on the danish butter shop cookies, with mice deterrent.
🤣 they're soooo good...

. . . bronze instead of copper . . . can't be used as a rivet.
