How do you cut your f holes?

I use a jig saw to cut the F holes roughly to shape. The final shaping is done with an assortment of small files, rasps and sanding drums. Keep in mind, for a carved top instrument, the F holes are originally cut small. The final step in tuning the box is to gradually enlarge the F holes to balance the treble and bass response.

This is another perfect task for "The Poor Man's CNC" Just make a template the same shape as the desired f-hole shape only three times larger. This particular "Poormans CNC" has about a 3x magnification. In the photo I'm cutting shell but the same system would be used to cut the f-holes http://goatrockukulele.com/Goat_Rock_Ukulele/slides/poormans.html Having a 3x template minimizes any errors in the actual size cuts.

Dremel, needle files, sandpaper. Still needs a little fine tuning.
