PIANO TECHS, WELCOME!

This website offers tools, training, and protocols that revolutionize grand regulating. A few minutes reading through the Grandwork System will give you the idea. Get in the piano what you set on the bench and way reduce time in the customer's home. Check out my summary of the benefits.

And consider the new Grandwork Weighoff Kit. Now, it is easy to balance a grand action to a particular balanceweight or to give all keys the same downweight with consistent upweights.

And try Coaching: online or over the phone. This service is available for any piano-related questions, on the fly or planned ahead of time. Call first and then pay me if I've been able to help. Have a Regulation Station or thinking of buying one? One of three Training Packages can help you get started or fine-tune skills already in place.

After two-and-a-half years, I can say that the Grandwork Regulation Station has transformed my action work. I’m enjoying the process so much more, and getting more accurate results in the shop than I ever thought possible.

It seemed like a lot of money when I was weighing the decision to buy it, but now I really wish I had taken the plunge many years ago. The hammer hanging jig is also a joy to use — the best one on the market in my opinion.

Thanks for all your hard work in bringing this technology to us!

The Regulation Station duplicates string positioning and keybed peculiarities and, combined with protocols Chris has developed, enables the professional technician to bring an action to the shop and recreate perfectly the in-piano bedding and strike. This saves hours when the action is returned to the piano. 

It has paid for itself many times over.

Six Reasons We Bought a Regulation Station:

1. Accuracy: You can rely on it.

2. Educational: Our apprentice gained an understanding quickly.

3. Ergonomic: Out of the “cave” into the light. 

4. Practical: Pickup actions, regulate in the shop, and return to the piano. 

5. Rebuilding: Install new parts without the piano with confidence that they will work in the piano. 

6.  Troubleshooting: Viewing the action from almost any angle with an accurate target, you can feel and see the problem.

WEIGHING OFF THE GRAND ACTION – Part 8

The mechanics of a grand action are brilliant, a series of levers that reaches inside the piano while converting finger force into a hammer force that can play strings with musical expression. Such a feat has many complicated details, but observed individually, they are logical, pragmatic – mechanical. Geometry is the design engine for this collaboration. And its leverages both transfer these forces and transform the distances they travel. Each finger’s mechanical advantage (2 kilograms to play a 10-or-less gram hammer) is divided by 5 in a tradeoff multiplying finger travel distance by 5 into a hammer travel distance that accomplishes fff. Or ppp.
