Undercutting holes

There were some informative replies to the “conical” question posted a couple of days ago, so I thought I would pick the collective brains of the forum on this one.

Why are the toneholes on some flutes undercut - what is the benefit? I played a flute the other day, which the maker told me was finished except for undercutting the holes. It played very well (better in his hands than in mine I might add) and I wondered what the improvement would be after undercutting.

Now I know I should have asked the maker there and then, but I was still in shock from the realisation that there was no going back and I WILL be buying one of his flutes - you know the feeling you get when you know that you can’t really afford/justify something but you’re going for it anyway!

So, who’s got the inside track on undercutting.

It’s all about tuning. Check here:

Cheers for that - information overload! Very interesting though. With so many variables, it must take dozens of iterations to produce the design for a great flute.

Does anyone know what tools are use for undercutting and to what extent the various makers utilise undercutting on their instruments. (Hmmm - like my brain really has space for any more information!!!)
