Hello group ,
I have a friend of mine that does a lot of boat repair and canvas
work on them as well .He is getting into boat building as well and he is
looking for a type of adjustable curve or batten for laying out long
curves and being able to put on the wood to transfer it .I have read of
these items but have no found what we are looking for .Any help on where
to look would be appreciated .
Either email me or post .
Thank you ,
Bernie

Or you may get some idea and make your own.

I think the traditional tool for that purpose was a wooden batten. Just a
piece of straight, straight-grained wood that seems to bend in a nice way.
I guess some old books on lofting would tell you all that you ever need to
know about those.

Enjoy!

A thin batten and a set of lofting ducks is what he needs. Holds a fair
curve without damaging the material.

Look into "The Gougeon Brothers on Boat Construction" page 118 (of the
2nd edition) or so. They show a simple method of transferring curves
layed out using flexible wooden battens. You should be able to find the
book at www.westsytem.com

Bernie,

I own those flexible blue strips that another fellow posted. They're
not much good for transfering long curves, because unlike a flexible
batten, they don't follow smooth curves. The curves usually end up with
bumps in them. They're more useful for complex curves that would be
hell to transcribe otherwise.

In "Yacht Designing and Planning", Howard Chapelle devotes an entire
section to drawing techniques and tools. If I remember correctly, he
uses bought forms for irregular curves and wood battens for regular
ones. His battens thin out towards the ends so that you get a fair
curve. It's worth picking up from the library. I gotta admit, though,
that after reading it I decided drawing wasn't for me.

I have one of the first type (blue plastic bendable) and don't really find
it that useful. I certainly wouldn't trust it to hold a curve while
transferring it from lofting to wood. (too flexible) For the same reason,
I don't trust it to generate a really fair curve; smooth, yes, but fair, no.

Rip out some wooden battens, and note that since you don't insist on a
constant radius of curvature, the width can be thinner where the curve is
more severe.
