After establishing my elevator skin bend locations I re-read some of Larry Winger's log entries where he commented that he had produced a tab in his Bend Line Spreadsheet for parts with three bends. This version of the file was (is) not on the ch601.org site so I requested the updated version from Larry which he promptly emailed to me. Thanks Larry! I'm sure this will be a big help on the trim tabs, flaps and ailerons.
