<DIV><FONT face=Arial size=2>The Calculating Technician is out of print. Does
anyone have a copy that I could beg, borrow or steal? On this topic, I've
heard that the calculations (or the approach) are not quite right. I wouldn't
know but would be interested in hearing any comments? Besides you gotta start
somewhere.</FONT></DIV>

<DIV><STRONG><FONT color=#008080 size=2>If any of you have and are willing
to share your scaling spreadsheets - please send to me. In response to Ric
Brekne's recent suggestion, I am offering to use my Excel skills to take a
crack at making a nice, user-friendly, efficient graphing spreadsheet that
we can all use to improve our study and understanding of this area of the
craft. I will compile the best ideas and hopefully come up with something
really useful.</FONT></STRONG></DIV>

<DIV><STRONG><FONT color=#008080 size=2>I don't presently know much about
scaling, but I do know Excel and have access to the "Calculating Technician"
Journal series where a lot of this was discussed.</FONT></STRONG></DIV>

<DIV><STRONG><FONT color=#008080 size=2>What do you measure, and what
formulas do you apply, and what are the dependencies, constraints and
