In one of the videos I noticed that the caliper being used has a round red accessory that fastens to one of the blades by a thumb screw. I have never seen one of these before and don't seem to be able to find one online. Does anyone know what you call them and where one might be obtained?
Don Jones aka Cody Conagher in Berkeley Springs, West Virginia has kept mine and my wife’s 97s running for 18 years. He’s one of the best in my book and his turnaround time is usually quick. http://www.codyscowboyshop.com/
