I've known Tim for ten years. He worked on my bass and rehaired my bow throughout my time at BYU, and I still bring him my bow to rehair when I'm I visiting Utah from out of state.
While I was working as the string instrument tech in the BYU Instrument office beginning in 2004, we took many of the instruments to Tim for more serious repairs--at the time, the most "intense" work I did was glueing open seams. Anyway, I was very interested in Tim's work and methods and asked him lots of questions whenever I visited his shop.
Now, so many years later as I'm getting into violin making myself, I was able to reconnect with Tim during my last visit to Salt Lake City in March. We had a great time talking shop and he showed me a few of his techniques. I tried out a few finger plans and some gouging on Tim's bench, roughing out my practice viola plate with his long-handled chisel and bench dogs that fit the curves of the viola as pictured. I like how he sets his plates in a cradle rather than just on the bench. It raises the height of your working surface to be more level with your elbow.
I absolutely recommend Tim. He's even rehaired Joshua Bell's violin bow, for crying out loud.
