Q: Some of the measurements are off a little
in Featherweight Boatbuilding, what are the correct
measurements?
A:
Here are the measurement corrections for the Wee Lassie
Drawings:
The
length of building board as shown should be Ten foot Seven and
one quarter inches. Actually it can be any length, the mold
spacings are the only important item here. I often set up a
wee lassie on a building board originally made for a much longer
canoe. The overhang on each end makes it a little easier in
placing the outer stem.

Here are the measurement corrections for the Wee Lassie
2 Drawings:
Stem
mold. Change the hight measurement from 15 5/8" to 15 3/8"
The Thirteen inch measurement should be 12 3/4"
Mold
number two- at Nine inches should be 13 3/8"
Mold
number five- at Thirteen inches should be 3"
Mold
number six- at Eight inches should be 3 7/8"
The
main thing is to fair your points, we use very close spacings
on the measurements for just that reason. In a normal table
of offsets your points would be three or four inches apart,
and mistakes might not be obvious.
Q:
Just how thick should the stem be?
A:
Five or six 1/8" (more or less-whatever will bend comfortably)
thick strips compose the inner stem. This of course is
mounted to the stem mold with masking tape in between otherwise
the boat will never come off the mold!
Q: How long should the building board be?
A:
It is really not significant exactly how long or short it is
(how far out it sticks beyond the boat.) It is good to
have it stick out as far as the stem to put a clamp on it to
hold the end of the strips "down". Later
when you are sanding you may wish it was a bit shorter... Featherweight
Boatbuilding shows a reasonable length. To lay up
my molds start in the middle and work out both ways using the
station locations from the plans.
Q:
I ordered the plans for the Wee Lassie 2 from you and
I have a question about the spacing on the forms. For the bow
section the spacing is clearly 13" but the stern section
is 12" on the plans. I'm not clear what the exact measurement
is. Can you please enlighten me what spacing you use. I'm setting
the forms on the strongback and want to get it right.
A:
The Wee Lassie 2 is not symetrical. The dimensions
shown (and described in the email question) are correct. To
our knowledge there are no errors in the fullsized plans.
Q: I started to make full-size patterns for
the Wee Lassie 2, but it seems that some of the demensions for
the profile/keel may not be correct as shown. Do you have any
corrections for those demensions?
A: This may be one of the discrepancies taken
care of in question 1 above. Perhaps the spaces between the
molds do not add up to the overall length due to the fact that
the mold thickness is not factored in on the plans or not being
factored by the reader. In any case, if the molds are set up
as specified, no one should be overly concerned about the overall
length of the boat being one inch one way or the other. In fact,
when stripping, how the ends are cut off will cause a variance
at each end that is negligible. moving a mold 1/2 inch or so
in any direction would have no measureable effect. Using the
full sized plans should help! Also - not worrying about the
overall length will help. Lay out the molds according to the
spacing and it is ready to go. No need to measure the overall
length and try to compare it to anything.
