New Knuckles -- Lighter Touch!

A heavy action can be made lighter simply by relocating the knuckles to a more advantageous position on the shank. But what position? And how is this job done quickly and neatly by any technician? Well, Nick will show you. From a simplified but useful discussion on action leverage theory, to actual in-class demos of the principles and techniques involved, this class will guide you through all the necessary steps. Highlights include a simple, shank holding and cutting jig (developed by Roland Kaplan), along with close-up video footage of all setups and operations. Also, see Nick’s adjustable action model which visually demonstrates the effects on downweight as knuckle and capstan locations are changed. As time permits, a discussion regarding relocating capstans will round out this useful class.

Bridge Notching – it’s all in the wrist, in the tools, oh well…

A class for you would-be bridge notchers. If you are a piano rebuilder of any level of skill, sooner or later you will be required to install a new bridge cap and then notch it.

What are the requirements for a professionally notched bridge? And what are the best tools and techniques for the job? Nick’s DVD footage on this work shows many excellent close-ups of the sequence of tasks and tools to get it done as well as many tips on how to practice before you set your hand to an actual job. On hand will be Nick’s assortment of chisels and tools, and these will be demoed in some on-site notching work.

How Grand is Your Wire Bending?

Grand damper wire bending is not something we do everyday, but when the skill is called for, we better be ready. Also, if you install a new back action or simply new damper felts these skills are critical to success. Come and see Nick demonstrate the processes of wire bending, head squaring, and neck bending (what’s neck bending?) Come learn what the three “Tees” of setting the damper head for best function and visual results, and see the required tools and jigs in action. The class will be combination lecture, in-class demo and video footage. If time allows a short hands-on segment will be included for a few attendees.
