#B
A pair of bend frames, but they are shown on framing plan with a larger number of spacers (but the but where this should happen is not so marked) I assume this is a mistake. Spacing foreward must allow for a sweep port.
The narrowing gap between this pair and #2 is important so as to allow remaining frames to be placed with appropriate spacing.
Measured and calculated several times, the gap on the keel seems barely to be enough
.
#A fore-regular
Aft a shift forward which at its upper futtock, widens to close gap to neighbouring fore#1.
This is to accommodate a pulley block above the sweep port (to be inserted later). I used a wider (7.3mm)blank and milled the aft part for the shift and lower fore part so the upper part remaining closed the gap to the next frame.
# The remaining frames :
Some confusion with the order/numbering.
With various hints and referral to the framing plan, it seems the order is (going forward) :-
Pair #1 (bend), #1B, #1A, #1O,#O (center) #AO, #A1
#1B - shift aftward and sweep port recessed more so gap to next frame is narrower than usual
# O- thinner frame -4.77mm-and each joint is framed by spacers on either side (also narrower than usual). The frame plans suggest fixing the first to the frames fore and aft (#O1 and #OA) but I felt easier to match by fixing the to both sides of #O.
Note these three all have cross chocks as bases.
Spaces between these frames are also narrower and as I seemed to be running out of space on the keel, made them at 1.60mm.
Nevertheless, when I dry fitted the last few frames I lacked 4mm. Not much, but the crowding was unacceptable.
One cause was the extra width allowed for the sweep ports until I learned that they were “countersunk” or recessed.
Anyway, some of the frames were not very good and I’d already made some other gaps too narrow.
Most of the problems were among the lettered frames ( that dyslexia again).
I removed most of the frames (alcohol) and remade completely 3 (#J,#H,#F)
Changed the casts to shifts where I had earlier made mistakes.
After a couple of days of remedial modelling, all fit with the appropriate spacing.
8 months of work -frustrating and satisfying- much progress in understanding and craft, but a landmark. Still to make ports, fairing etc and still on ch 3 vol 1 (of 3), but a landmark nevertheless.
IF I CAN DO IT, SO CAN YOU!!
