Totally fascinating the way this thread got hi-jacked. I'm sick at the moment, so having some time did a vanity search and read this entire thread.
I found reference to a quality concern because of rusty tuners on one of my ukulele which led to speculation that though bearing my name, the ukulele was built by one of my students. Not sure about the logic here. Anyway, I build all the instruments that bear my name. In recent years I have used skilled craftsman to assist me in the build, as did Mya Moe, as does Rick Turner and other builders. They bear my name because I pay them to work under my direction, to my quality standard on aspects of the build.
For instance - I cannot hand sand any more. My assistants do that. I can still carve so I do the neck. All of the components are made by me but may be final finished by my assistants. I cannot manipulate my hand to do the complex operation of gluing on a bridge - my assistants do that. I spray finish and set up all instruments, make the decision about wood combinations, book-matching, grain orientation and all design modifications and decisions are made by me. Just FYI - you can use this for future reference.
However, students on my course build their own ukulele and sign their name in it. Some have asked me to make a label that says'Made in the workshop of Pete Howlett' which I have declined to do. It's their work and they should own it.
And yes, I love batch production - of parts. And I like making limited editions (limited run special) which I do almost entirely myself.
I hope this deals with the 'side bar' in this thread.
As for Juha Lottonen. I have met him twice in Finland and have toured his workshop and exchanged wood samples. He is a gifted luthier (he went to luthier school) and is a very 'clean' and meticulous builder. In my opinion, if you live in Scandinavia, he is your go to full-time builder. Sven in Sweden builds part time, contributes here and also builds great ukulele.
