1769Re: [AtkinBoats] Problem in the Lofting
- Jan 31, 2008The + sign means the actual measurement is a little over the stated dimension and the - means it is a little less. So if the measurement was 2 10 1/2+ then the actual measurement is a little over 1/2". This would be easier to pick up if you gave us the smallest fraction used. Let's say everything is in 1/4" increments, then the +/- would take you to the +1/8 or -1/8" from the stated point.
Hope that helps

Subject: [AtkinBoats] Problem in the Lofting
I recently receive the plans for the Maid of Endor that I order, when
I started studying the plans I faced my first problem, the table of
offsets has some numbers with the signal of addiction(+) and some
with the signal of subtraction (-) for example 2.10¹/²- or 3.10³/²+,
if somebody can tell me what the signals means, I would really
appreciate the help.
I bought the Greg Rössel book "Building Small Boats" but there
is no example of numbers like these using the signal of addition or
subtraction, although the book is very good in the part of lofting.
I think is obviously that is my first lofting and if there is any tip
of you folks, who have already pass by these problems I would really
appreciate the help. Thanks !
