Breaking news item: Lowell Component Downbearing Gauges are now available from Pianotek. I have a question regarding the instructions for measuring downbearing: "Multiply the number of divisions the bubble crossed by three and one has the front or rear bearing, in thousandths." My high school chemistry teacher would string the author of this gibberish up by his/her thumbs. I can hear him now: "Where are your units? Without units this means nothing!" Thousandths of what? Inches I suppose. But what does that mean? So I have a couple thousandths of an inch of downbearing - what does that tell me? I don't have a backscale length. The only thing that means anything is an angle. Angles are not measured in thousandths of an inch - it is not a linear measurement. Are they trying to suggest a slope maybe - as in so-many thousandths of an inch of vertical length per inch of horizontal length? The author should get a job at NASA and send another rocket crashing into Mars..... ;-) Terry Farrell Farrell Piano PS: Units - a little pet peeve of mine! www.farrellpiano.com terry at farrellpiano.com -------------- next part -------------- An HTML attachment was scrubbed...
