CLASS: "Friction at the Center Pin, More Questions than Answers?" by Robert Springer
DESCRIPTION: This class aims to refine the way in which we approach defining and measuring center pin friction. It will also present current and ongoing research data which might suggest that when repining center pins, what we think is happening, might not be happening. Attendees are encouraged to bring a calculator, pencil, paper, and their preferred tools to measure shank flange friction.

CLASS: "Aligning Dampers / Spot Voicing and Fitting Hammers to Strings" by Nick Gravagne, RPT
Two subjects:

1) Before gluing on damper felts, the damper heads and wires must be properly aligned. This is not hard if you follow the simple procedures Nick will show you. For example, do you know what neck bends are, what they are for and how to make them? This material is good to know even if you are not replacing damper felts. So that all can see clearly, a video of the work will be shown.
(Class time about 30 minutes max with discussion)

2) Spot voicing with the chopstick tool, and fitting hammers to the strings without removing the action.
(Class time about 20 to 30 minutes)

See y'all there!
