August 2010 - Mojo Mouthpiece Work I show and discuss how gauges for facing work have evolved over the years. I measure a twisted tip on a tenor sax hard rubber mouthpiece. mojomouthpiecework.com
I use a total of 15 thicknesses. They are auto engine thicknesses that are easy to come by. I also use a 0.001 that has found crooked areas that the 0.0015 didn't find. But my 0.20 has been the greatest help, because it finds errors where 0.24 is the same but not at 0.20. It was startling how much this 0.20 mattered and made such a huge difference.
I find if I make sure my facing adjustments are smooth without tiny flat spots, the feeler spacings I use are a good balance between speed and precision. I look at light reflecting off the rails to see flat spots and kinks.
