It's Fun to Play the Piano ... Please Pass It On!
If it is the floor model I visualize, it will need to have a certain amount of mass to keep it stable. Which means that shipping cost could stifle the sales potential for the machine.
Perhaps just produce blueprints for techs to build the machine or have it built for them locally?

Or leave a shelf or box that could be filled with sand or rocks.
Personally, I am not interested. If a part sticks, it will stick when it is pounded, so it will not wear in anyway.

It has nothing to do with sticking parts. If parts are sticking, your repair and regulation is incomplete. Finish doing that work before you hit the switch of the pounding machine.
Pounding machines are used to play all keys vigorously, usually about 20,000 times or so, after which a final regulation, voicing and of course tuning takes place. This will result in a piano that is much, much more stable in tuning, touch, and voicing after delivery.
I see that Rod has found a source for such a machine that I was not aware of. Thanks Rod!
Hi! I´like to revive this post because Im restoring about 20 pianos for an institute, and after replace all felt and bulkskin from the action i have to regulate again about a month of use, but they don´t play all the keys and the compression on the felt is not even. Who wants to wait and regulate over and over
I have draw some ideas of a 2 lever pouding machine like the one on the video but to be place on top of the piano to avoid that big box. I haven´t build nothing yet,
I´ll love a electronic one with solenoids but still to expensive and more living in mexico, I have talk to a WN&G tech and they have design a pounder over the pianodisk system, the hardest part is to hold down the solenoids up side down with springs.
The playola is too old and for the price, the lx system is far less expensive than that and better,
Who has more ideas, pictures or drawings of your machines? I guess most if not all restorers should have one on the shop.
someone here has an old (but not to old) un-used pianodisk system or parts sitting around the shop getting dusty I´ll be interested
I´ll apreciate your comment
Thanks

I learned to pound with 2 hand pounders, then a regulation pass is necessary. And earplugs Keyboards are stabilized with a long lever that push on the underside of the pinblock and an adapted woodblock above the balance (als used to lower a key that is only a little high) balance punchings where ironed before installation, also , it does not make them so even but it helps.
Using first grade paper punching is also a must. The ones sold by Yamaha are good, not too sensitive to moisture and rigid enough.
The machine pounding is more efficient for the hammers and the action, but hand pounding can be firm , also on a new stringed piano you have to tune hard 4 times and that pound also , regulation passes and voicing are inserted between those tunings. I will pass the exact procedure.
So I always have think I need a machine, but can live without it. I believe the machine pound not so hard, also , I asked how many strokes and had no precise answer, but even 10000 have been said to me too much.
Do someone know an exact range ?
Ps felted blocks in wood (leaded) are placed on the strings to avoid too much noise , it also make the pounding more efficient. (not anyone agree on this, but the noise is really too much, I also dont like to pound strong on bass strings)

The idea of the pounder is to effectively and quickly put the equivalent of 10, 20 or more hours of playing onto the new or re-built piano. In factories, this noisy process is done in sound insulated rooms. It seems they want the strings to resonate freely. At two blows per second, a pounder can rack up 10,000 keystrokes for every key in short order (extended lunch break!). This would be hard to beat pounding by hand.
I asume that no body owns this kind of machine machine? it really ironing is enough to break down a new action or restored one
But the thing here is to built one! now what will be better built it over a pianodisk or QRS, or have a mecanical one?

Ironing ? only the balance punchings can be ironded , that is for better stability of keyboard leveling.
Ironing does not pound the hammers, I was talking of pounding them against the strings, or against a heavy wooden block , a bass hammer can be installed in a handle to make a one note pounder.

I know of one tech that uses a custom made (by him) fitting on the end of a electric Jig Saw. He holds it over 6 keys at a time and pulls the trigger. Better than nothing and nothing is common.
