Just curious to know some of the methods used to create sound ports on the curve of a side and also how oval sound holes and oval rosettes come together?

Side port: Forstner or sawtooth bit, from the inside.

Oval soundhole or rosette: router and template.

you can check out past threads to read howard's explanation about drilling from the inside.

another option for a soundport is to use a dremel with a spiral bit. i just did one this way and it worked great. i had the dremel mounted in stewmac's base. my shape was an elipse. but if you want a perfect circle, i'm certain that howard method makes the most sense.

After drilling a hole for a side sound port, you can then enlarge and shape it with a little sanding drum on a dremel.

Less splitting, because you are cutting downslope to the grain, due to the curve of the side. Ordinarily you get less splitting on the entrance than on the exit. The curve makes this work differently. Still good to have the wood backed up with a formed block on the exit side.

This jig, with a downcut spiral, slowly - no tear out - (I have even done this on finished guitars, and no finish marring either) .. usually after the two coats of zpoxy are done .. quick sand, then the thinned coat of zpoxy, then finish.

I also have templates for other shapes as well ... BTW, it uses a template guide on the lam trimmer base, I usually go 1/2 inch guide, 1/4 inch bit.

Another pic ....
