: I know what you mean--but tables of offsets routinely go down only
: to eighths of an inch, and 16ths are simply designated as plus a
: bit or minus a bit.
: Trying to bend wood chines to get accurate curves from points which
: are only approximate can cause different builders to come up
: with slightly different forms. How different? probably 1/16th to
: 1/8th inch. An aggressive day with a sander can affect the shape
: of the hull by that amount, too.

: I think we overdo the number of frames we use. For the sake of
: convention we space them a foot apart for kayaks. With older
: plans for canoes they are frequently 18" apart. They only
: need to be at points where they will influence the bending of
: the strips. If this was a vector-based drawing we could call
: those "control points".

: If I was making frames for a living, and couldn't afford to buy
: CAD/CAM equipment, I'd make hardboard templates and cut the
: forms with a router with a pattern bit.
: it would be more consistent than cutting each set freehand, and
: much cheaper than CAD/CAM. Maybe their jig slipped.

I agree with your comment about the form spacing Paul. I'm almost done with my Black Pearl and this 19' 5" long boat only has 12 forms spaced 45.5 CM (17-7/8") apart. It actually made the build much easier and faster, fewer forms to line up!
