Does the Fandrich action have bridals?

I have seen an action that just had a rail behind the jacks instead of bridle straps. When the action came out, the jacks were held forward at a point where they would go over the butt felt when the action was replaced.
If the bridle straps have a noticeable effect on repetition, it would be noticed on all the pianos that have broken straps.

It is more noticeable under certain playing situations such as playing slowly and during certain types of repetitious playing.

It also keeps a continuous mechanical connection between the player and the hammer.

If you can diagnose a broken bridle strap by playing, without removing the front board, more power to you. I cannot, and I do nor know anyone who can.

Do this experiment:
1. Unhook one of the bridle tapes.
2. Move that hammer and a neighbor to the strings
3. Release the hammers
4. See which one gets back to rest position more quickly.
They also keep the hammers from getting as far ahead of the jacks as would occur if there were no tape.

Sorry, I cannot do that without looking at the action, so it does not count. Besides, there is too much crud on top of my upright.

There are many adjustments that would be difficult to diagnose on a grand action just by playing, but that does not mean they are not important or relevent.

During playing I do not think this is would be valid as the hammer is rebounding faster than the sticker assembly will fall by gravity.

Hey some great pictures here, thanks Erus for the unusual action parts there, and Ryan for the Renner assembly, some great inventions for sure. BDB, The action that I showed from Schwander, has that rail too. It keeps the jacks from falling out while that action is removed I forgot about that part, and failed to snap a photo of it, thanks for the reminder. Can we see a picture of all of the crud on top of your beloved upright? Like Ryan, I need to see if it is more crud than on mine…..  www.silverwoodpianos.com

While working in the shop today I had my wife unhook a bridle tape in one area of the piano. I was able to figure out which one was unhooked just by playing and not looking. Without the bridle tape there will sometimes be more space between the parts, what Darrel Fandrich has called "dynamic lost motion".
Apparently the myth that the bridle tape's only function is to hold up the wippens is still alive and well. I thought Jim Ellis closed the book on this subject when he published his study in the Journal.

Those were amazing pictures.  The PTG foundation maintains an action model museum. I wonder if they've ever come across any of these.

I have sent those pictures to Jean Jacques Trinques the Director of the AFARP in France. He was very interested in the pictures/design and I am still waiting for some info from their history centre there. Here is a translated page for that place, a museum in France. http://translate.google.ca/translate?hl=...Afarp%26hl%3Den Because that action was in a Canadian Mason & Risch upright, I am leaning towards the fact that it might be a prototype that did not catch on or something… have never seen another one ever here….no-one has….. www.silverwoodpianos.com

If the bridle strap helps the hammer fall back, it is because of a problem with the butt spring, which unfortunately is sometimes a design flaw in modern actions. As a matter of fact, it is common to see a broken strap when the butt spring is out of place, because then the strap is pulling the hammer back.
When an action is properly regulated and there is no excess friction, the bridle strap never becomes taut. So it cannot have any effect on playing, except for its weight.

That Pianophile box is supposed to have real bridle tapes in it. Perhaps he or she saw the light and is ready to do it right.

The box is from pianophile, it's full of bridle straps waiting to replace the twist ties ties. I made money on the job. The pictures were taken by me, NOT the original DIY, whom I would have enjoyed meeting.
