Keep planking(12032012)


Having had only 5 attendance today, we kepts planking on and one team lofted the topside for cutting it using spiling plank.



We can hardly see the line for cutting through the plank longitudinally, which is for making sure that it can let the plank more twisted forward because of more shape on it, whereas not likely on the stern which we left the plank widely. The advantage of this method is we don't have to make narrower strips all the way long but it is a bit hard to glue between those gaps, we can use paper tape though.


Spiling planking is running the topside frames. Measure easy measurement like 100, 200 from both of the edges. Prior to doing this, make sure to draw a line following station line on the pattern. Such a method is the one that we adopted when we were making the topsides of Don's dory. Foam is going to be butt joint. If they get scarphed, they lose their advantage of flexibility but I'm concerned about the joint part has too much load or stress on it.


One planking being chipped off last week was cut out today by using jig saw and hand saw and we fille the gap with that small piece of planking. It doesn't look bad indeed, we know how such an accident can be fixed as well.



Taking the nail off, sanding it.

dryfitting, we've got pretty far.


lofting


all planks fit in where they have to go before glueing. We've only left some gap just under the chine each side and topsides which Lance is working on. It takes longer than I thought but we can obviously finish it by tomorrow. The last planking was sort of tricky but not that hard. I measured the length of the gap on each frame, tranferred on to the planking, use a batten and drew a fair line but I have drawn straight line on each section and planing, fit it.


We used paper tape, two pieces of wood and a clamp but we still have some gap below that part.


View from station 0(F.P). We halve and halve half of the planking forward but we couldn't really fit those plankg onto the frame, which should have been.


grab those planks to make them flush


We haven't finished both sides. Only starboard side was done.


Cutting the foam rougly but quite exactly and get them butt joint. We are goint to cut them into finish size and put them on the frame. We can do it.


Tape is supposed to be used to prevent sanding excesss glue along the joint. Plastic for let cardboard and foam not stuck each other.


another view


There were three part longitudinally but the last one was not wide enough so it had another piece on.
