And for those comments about my alignment gauges, I have indeed updated the newest ones so that the target plate that rests on the stylus tip and cantilever is adjutable in height so that greater accuracy is assured. THe math was repeated many times to ensure accuracy, and I can promise you that these gauges will give you an accuracy that is as great as any off-arm protractor. And yes, we now have three different gauges for the 3 arm lengths of (nominally) 9,10 and 12-inch.
Thanks for this information Bob. I will get an updated guage.
Can the updated alignment guages just be ordered through normal retail channels?
Thanks
