I used a side reference shot of the Ubersaw from the TF2 wiki and scaled it in Photoshop to fit my hand proportions then I printed the scaled picture.
Since the print out was in two pieces, I just trimmed the white space between them and taped them together. I also cut out all the additional white space around the image.
After trimming, I copied the shape's outline to a piece of poster board for the "core" layer template and then mocked-up additional layer templates.
Templates are good to go! Now on to cutting!
