Bulldog, love the video!
Couple of things- I believe it was Rocket car that came up with the idea for the tuning board start rail not me, I just pilfered it! But I have posted several time on how much I enjoy using it!
Also, I believe Lightninboy came up with the speed square tool for checking alignment. I pilfered that tool also! My tuning board has a high sidewall on it so I use the speed square on the inside, I milled off the bottom lip of the square on mine so it would lay flat on the table. I added felt pads so it slides smoothly and won't scratch the glass.
