Old Track & Balance Photos
Hi All,
I'm looking for some old pic of the first methods of do a track and balance.
The main one I'm looking for is one of the flag method, where they used a piece of canvas stretched between to poles then marked the blade tips with chalk. They then moved the canvas slowly into the path of the blade tip so the tips are just touching the canvas and did the track adjustments from the chalk markings on the canvas.
If any body has anything please let me know, there might be a small finders fee if the image is hi res enough.
Thanks
