And beside, I figured it wasn't right anway because nearby, shoulders or legs would be deforming the curve three dimensionally, while you were doing a series of two dimensional sections. No egg.
Item #2- Length...I grew up with a slide rule and still have a six incher w/ leather case lost in some drawer, so the difference between 102 and 100.75 is not "significant." If, on the other hand, especially with the inside back piece of wall molding in a closet, you had cut to 100.75 when you needed 102, you would have spent the entire night on line searching for a good quality wood (or fabric) stretcher, or a reverse cut saw blade, so that you cut restore the original length. In any case, being a tad over looked to my practiced eye as just fine. Again, no honest egg.
However, I thank you for pointing out to the world the difference between theoretical calculations and engineering measurements. You're young enough not to lost confidence in the numbers, while I've retreated to first cuts always longer than I know I need.
And take none of my teasing as anything other than appreciation. Your vids are always fun and I'll bet around the campfire with you is too. BTW--What were your epilogic words after mentioning Gutermann thread..."it looks quite sturdy______?"
thanks, Ken
