What do y'all use to cut your f holes? I have used a big rotary blade attached to a drill but am looking for something less aggressive. Any recommendations?

Good idea to tape are to be cut with masking tape first. Then sketch f-hole lines. Cut slow & deep with multiply passes to get a nice clean cut line. Then use a forstner bit to remove the bulk of the area to be removed, keeping slightly off from the cut line. Then trim with blade and remove tape, then sand smooth.

Thank you Farmer Ted.  Ill have to play around with one of my old boxes to get a feel.

I use masking tape on both sides of the lid. Then sketch them out on the tape. I then drill a hole on each end of the long part. I use a Dremel tool with a router type bit and remove material inside the lines. When they look pretty close remove the tape and sand the holes. I do a little trimming with an exacto blade. About half way thru the process I'm wondering why I didn't do regular round sound holes. Then i post a pic and one of you guys says nice F holes and I'm on it again. I'm getting addicted. Sorry if I copied what you wrote Scott.

I love the "and what was I thinking?" comment... too true!

Anyone looking for F-hole patterns, check this link out....https://www.google.com/search?q=f+hole+template&client=firefox-...

I have a pattern made up on the computer with a center line and printed it out. This gets placed on the top with a carbon paper under and the pattern is traced. I take a small drill bit in a rotary tool and drill all around inside the lines. Then I have a modeling saw with a small key hole blade. I use it to cut between the holes. Finish up with some Dollar Store emery boards.

I tried a fluting cutter bit in a rotary tool. It was too agressive and wanted to wander. I think with a proper template so you could just punch the fluting cutter through and go, that might be the way to do it efficiently.

Every time I do it I go Arrrgg and swear there has to be a better way, but I really like the effect.
I use the saber bit tip and the adjustable foot on a Rotozip to cut all my holes (or the same bit type on the Dremel with the fine tip extension), F or otherwise. I can freehand pretty well, but for F's I copy one off the Web, then use the old pencil graphite transfer method onto the soundboard. I start slow, and just follow the pattern, being careful to cut just to the inside of the line. I finish up the edge with small files and sandpaper.

I drill a hole at each end and use a fretsaw,finishing off with needle files/sanding
