I have updated the spreadsheet
1) seperated left and right adder, before it was one length added to both ends
2) some input for the 1.75" tube was incorrectly linked to 1.625" tube
3) added the 5 bend illustration
4) put a conversion chart on each page (sixteenths to decimal)
it is difficult to consistiently enter distances in fractions so I left the "INPUT" in decimal form and the "RESULTS" are in fractions, even that has something to be desired as 1/4" will show up as 4/16".
any questions or suggestions are welcome. it's not difficult to use and works really well, just spend a few minutes playing with the input numbers and watch the results update. be certain you set the tool lead-in and bend radius for your bender.
if anyone knows how to "deposit" the spreadsheet somewhere where anyone could just download it that would be fine with me otherwise email me and I'll send you the latest copy.
enjoy it
