His credentials and awards include a BA from William Paterson University, an AST in Mechanical Engineering, and the PTG Member of Note Award. Nick most recently received the Hall of Fame Award at the Annual Convention in Seattle.

A new class with a new look at how to examine and analyze the piano action. Along with some basic coverage of leverage relationships, this class will go on to discuss how to lay out and measure the three components and six levers of the key, whippen and shank. For example, should we measure on the diagonal, or on the horizontal, or is there yet another way? Here’s a clue: how would an engineer or physicist approach this machine we call a piano action?

Related topics of interest will include torque, inertia, and gearing principles as these tie in to our subject. Dr. Walter Pfeiffer, famous in our little world for his books on action investigations, will be cited where relevant to the discussion.

This new class will be presented through colorful PowerPoint and video and props and action models. If you wish to gain further insights into this fascinating subject, both theoretical and practical, you don’t want to miss this class!

Aspects of String Scale Design - Problems and Solutions

Tremaine Parsons, RPT

Tremaine ParsonsTremaine Parsons, RPT, was introduced to Piano Technology in 1969 when his piano technician (after a fourth call back) taught him to re-glue upright jack posts using two kitchen knives and a piece of coat hanger to clear the mortise. Seeking higher standards, Tremaine attended North Bennet St. School of Piano Technology for one year graduating in 1974. While building a successful tuning, repair, and rebuilding business in the suburbs of Boston MA, Tremaine became interested in computers during the mid-80’s and released his first version of Pscale (piano scaling program) three months after seeing a demonstration of the Atari scaling program at a chapter meeting held at Inventronics in 1989. In 1992, Tremaine relocated to California and, while building a new tuning clientele during this decade, established Sierra Software Services, ported Pscale to the Windows platform, developed the Ptools Client Management program, and was recruited to create numerous web sites for small businesses in his area. In 2001, Tremaine established an Internet Service Provider company offering low cost Internet access and Web Hosting Services. To date, Tremaine has and continued his avocations in Piano and Computer Technologies.

This class will explore several examples of String Scale Design anomalies or problems in common piano brands (old and new) familiar to most Piano Technicians. We will use the Pscale String Design software to rescale at least one example with supporting “before” and “after” audio/video “proofs” of the anomaly corrections. Additional examples will be presented using Pscale along with audio “proofs”. If time permits, we shall examine a number of additional string scale examples that demonstrate better and worse case scenarios from a more general perspective. This class will also prove valuable to “non-rebuilders” in a better understanding of  “Tuning across the Tenor/Bass break”.

Grand Action Rebuilding

Kathy Smith, RPT

Kathy SmithDavid Vanderlip and Kathy Smith are a husband-and-wife team with a varied business in Southern California. They have both been in the piano tech business for over 30 years. They work with schools, concert halls and private clients, and have a small rebuilding shop at their home in Anaheim. They are both active with the local exam board, giving tuning and technical exams to six chapters. They have both been teaching, together and separately, at local chapter meetings and regional and national conventions, for 20 years.

Rebuild a grand action, starting with thorough key frame work, including key bushing, polishing pins and capstans, backcheck work and much more.  Then emphasizing efficiency, we cover parts prep, installation, alignment and regulation.  Other great classes describe parts selection and geometry - this class takes it forward from there, for a quick, accurate way to get a stable action working at its best, with many slides of tools, jigs and techniques.

How to Install the New WNG Damper Action

Bruce Clark

Mike ReiterLead design engineer for Wessell, Nickel & Gross and Mason & Hamlin. Involved with piano making and design for the last 30 years.

While the WNG Damper Action is a vast improvement over the traditional American damper action the installation is approached differently. This class covers why the damper action is desirable, the tool kit WNG created to aid the installation of this damper action, selecting the features required for the piano you are working on, ordering, making a scale stick, drilling and tapping the rails, assembly and installation into the piano.

Recapping the Vertical Bass Bridge Without Removing the Plate

Christian Bolduc

Christian BolducChristian Bolduc is a technician specialized in soundboards and pinblocks (belly man).  Christian is a cabinet and furniture expert.  He studied cabinet making at the Ecole du Meuble de Victoriaville and spent one year at the Schimmel factory in Braunschweig, Germany studying piano structure and design.  He is a constant searcher for new ideas and methods to make your rebuilding projects easier.  Christian is the factory manager at Pianos Bolduc.

An easy way to replace split bridge caps on uprights without using epoxy or other glues to fix bridge pin problems. Learn how to build a jig over the plate to remove the old cap and glue the new one. This technique can also be applied to grand pianos. A DVD of this class is available.
