WoodTrax is a program for home hobbyists, which will take a string of
text (usually a name) and make a printible outline of it so that it can
be sawn into one piece for finishing.
I can think of a couple of free ways to do without a special program.
You can download "outline fonts" that can be used in any word
processor or even Wordpad. Just use a huge point size, type and print
(you are not limited to the sizes shown on the list in your word
processor... type in your own size number). Some general-purpose
drawing programs and word processors can render text in *any* font as
an outline (I happen to use OpenOffice Draw). There are plenty of
free fonts out there; you need only find some that work well for your
woodworking.
