Dear Esteemed Engineers: We, on another thread, find ourselves in a dilemma. The problem is that we are having a difficult time coming up with the right tools and methods to get an accurate measurement on a certain structure. The flexible, hidden nature of the structure makes it resistant to traditional means of measurement (i.e. ruler, depth guage or calipers). Hopefully you all, the OR brain trust, can shed some light on the subject, which resides here: http://www.ohio-riders.com/showthread.php?p=284045#post284045 go to about post # 212 or so. Thank you, that is all.
