That is an impressive system. I had not seen the video yet.
Although what we use is not designed for one man, it is a one piece jig that is universal with no extra parts. I have used it to set up a grand with no help, but it is not as slick as the Moondog product, for sure.
Thanks for sharing Steve.
PS - For those interested, feel free to watch this video of my guys setting up a grand piano using our jig.
