Vertical piano regulation - let off 

That is a good idea. The more ideas the better. One thing nice about this technique is being able to vary the letoff distance. If a mute strip is used, the letoff needs to be more than 1/8. In pianos that have a tendency to hammer “bobble” I have hammers letoff slightly farther from the strings in order to have that slight bit more aftertouch. Thanks for your comment!

Thanks! Be sure to read what I wrote in the description.

It’s also so much better on our backs when we use this let off method. Glad you liked it.

I’ve used 1/8” let off very successfully. Maybe 3/16”, but never 1/4 and larger.

I have 2 boards: one is 13 3/4 long, the other is 16 1/2 inches long. Most of the pianos I regulate are Yamaha’s 16 1/2 is the length of the bass and treble, 13 3/4 the middle section. It would be possible to have a shorter board and set another sample in the middle, but it is more efficient to have one board for a section. The width is 29mm, a measurement I use to set damper lift. I’ll make a video of that process soon.

Correct key depth is as important as let off point. I don't use the tool in the video, just paste temporarily a 2 mm thick cardboard strip on the strings so I have my two hands free. I worked for years for the Yamaha company and we followed rigorously a 24 step procedure of upright action regulation to eliminate every possible malfunction. The textbook Basic Piano Technology is unfortunately not commercially available and is guarded as a sort of company secret.

@@christianwouters6764 Thanks!

But it’s a very good looking mask.

@@lucyurlacher9794 your smile is priceless. Time to toss the masks................

Do you know this regulation technique? The regulation procedure is what is important.

@@lucyurlacher9794 of course not. That is why I am watching you. Very cool technique Mr. Spurlock came up with. His retirement is too soon.

What’s the size of this piece of wood that you used to approximate the hammer to the string?

You looked at my mask and didn’t like the regulation technique? How does that make sense? If I was alone, who was doing the video? There’s some logic!

Lucy, seriously. Obviously you're afraid and bought into the mask bs. They don't do squat save make you look muzzled, which actually, you are. Interesting that throughout the last 3 yrs business has grown.
