A few months ago, i decided to make my own piano key pounder for mating the hammers to the strings. I wanted to make it with as little cost possible. I even challenged myself to make it out of wood! Along the way i had to work out the bugs of course, and i just completed the latest modifications. The problem turned out to be, that a pulley should be supported on both sides, not on one side. I had to remove one of the pounder pads in the bass, but that's okay because the unichords don't need to be mated anyways. Since i used a salvaged motor from a treadmill, this thing only cost me about $20 in scrap wood to make.

If you watch any of the videos, just be warned, its close to the worst sounding thing you'll ever hear.

Wow! Just wow. Before watching the video I thought your warning was an overstatement. Nope! I gave my wife, who was sitting across the room, quite a start. After watching the video herself her question was: why isn't it pounding the bottom few notes?

I built one of these twenty some years ago. The noise was so bad that I finally gave up using it. It just wasn't worth it to me. I've developed other strategies that accomplish the same thing without driving me nuts!

Yes, i'm well aware of those other strategies, unfortunately they take a long time. As i have said to other techs in private conversations, the key pounder is another tool in the toolkit. I figure it saves me about 40 hours of tweeking work when i'm striving for a pure, clean and even tone across the compass.

As regards to the noise, i have developed the perfect solution. I drape a blanket over it and go for a 15 minute cup of coffee. It's almost to the point now that when i play the youtube video, i crave a cup of joe.

Small world. I never before made the connection between Pavlov and the piano. laugh

I guess a coffee craving beats a keybed soaked in saliva! blush
