I've read about Dennis Havlena on Mudcat for years and bookmarked his site years ago in the hopes I would some day be able to make a hurdy-gurdy using his plans. A current thread reminded me of him, tonight, so I went looking for his site as a link in a thread was broken, and found himself demonstrating his home-made instruments on youtube: Click Here. It's great to actual see the person behind all of the creative stuff he has on his website!

Dennis, if you are reading this, thank you!
