Oh yes, don't let the high tech fool anyone. Further into the tour it's nothing but hands on work.
Since I'm on the "Martin " theme here is a link you may enjoy that is totally hands on work.
Willard Martin ( not related to the Martin guitar family) is quite well known for his custom harpsichords and lives nearly next door to me in Bethlehem, Pa. At one time I made strings ( like I said, all hand made ) for his instruments. He builds everything from the cases, to the soundboards, keys,,, well,, everything by hand. Beautiful stuff and a very interesting and smart guy. Check out the link.
The closest I've come to building an instrument is a Hammered Dulcimer. But this guys stuff is mind boggling.
