This is genius! Only I wonder if the regulation isn't an awful lot of painstaking work. A vertical piano will never be able to compete with a grand though, simply because of the gravity that works on the hammer. But this must be an improvement for sure!
Indeed! The regulation of a traditional Fandrich action is an awful experience. While It is worth the effort , ouch. My coworkers told me that if I wished for them to regulate any more Fandrich Action’s they were going to quit. I could not blame them… But instead of that we have come up with five new inventions which our lawyers are busy patenting. Now the process of regulation is literally child’s play. If you are interested drop me a line. It takes us about three days, sometimes four to rebuild an action with this new technology. Great results.
If you have a spring instead of a bridle tape there is resistance as the hammer rises whereas the tape makes no resistance going up but quickly jerks on the hammer butt to pull it down . The tape on your model is far too loose and would not work properly just like thousands on upright pianos all over the world that are left loose , because nobody understands how they work .
Actually the Fandrich type of upright action doesn’t need or have either a tape or bridle wire! We sent one to a university in Europe for analysis and a thesis proves it to be extremely improved over a traditional upright action. Depending on the parameter tested, speed repetition and latency… averaging about 250% improved. We have just patented some manufacturing and rebuilding variations and are considering bring the results to market. Darrell got the action right, it was just difficult to make and adjust. Luckily it needs less maintenance than other actions. Thanks for your comments. Oliver
First, Darrell got the idea from me to use a grand knuckle in an upright after he tuned my Mammoth Piano. Second, making these patented modifications are illegal without the consent of the Fandrichs. I believe Heather or Stephen are the patent owners. So out of respect get their permission.
For your information, I am not infringing on any patents. Furthermore, before he died, Darrell encouraged me to keep going as does Heather Fandrich,John Rhodes etc. Thank you for your comments however they are a little harsh and somewhat incorrect.
Isn't it an upright version of the Blüthner patent action? And isn't it simpler to use magnets, like Steingreaber and Seiler? I wonder what's your opinion!
