I frequently use a stick of chalk to lay out shapes on wood. If you need something more precise, and assuming the wood surface is smooth enough, you can lay a xerox copy of the part face down on the wood and go over it with a warm iron. This transfers the toner to the wood.

: just guessing but

: a white pencil crayon?(hard) charcoal artist pencils?(softer) pastels(real
: soft)

: i've often sprayglued on(very lightly on the paper not the work - if the
: paper's light and the work curved, it'll conform somewhat - who cares abt
: some ripping)light tracing paper and mark that up and cut to the lines
: etc. Then no part of the work is marked. and the paper just peels off. and
: you can redo it and redo it.

: a chalk line and move the work around snapping to the lines?

: masking tape wrapped around at intervals along the work and mark that up?

: reall thin masking tape and use the thin tape as the drawing - will conform
: to curves and be pulled tight to be fairly straight.

: some ideas
