re: Oval cut

The elliptical jigs are great, but then you have to do another project before working on the desired project, and you might not make something oval again for a long time. Seems like wasted time to me. I would go the way Bondo and Paul suggested. Quick, easy and accurate.

About the jigsaw, I owned quite a few DIY jigsaws through the years and none of them were any good. I finally bought a Dewalt quality jigsaw and it is remarkably accurate. There are other professional quality goo jigsaws out there as well. You will never regret the extra cost.
