In the Sharpening Doctor: Conclusion video Mr. Rogowski says:
” Now we can take shavings half the thickness of a sheet of paper. Oh boy does that make a difference in the fit of a joint. “
Oops we are talking .0015 inch = one and a half thousandths.
There you have it. From the official dude. For all those who say a thousandth or two makes no difference in the realm of woodworking and the fit of a joint . . .
I rest my case ( argued to the death some months back ).
Thank you very much,

I had the opportunity to be one of the students with Gary. It was great to spend 2 days doing nothing but sharpening, I hope you all get as much out of it as Aaron and I did.
Yes it was a nice feeling to take that whisper thin shaving in order to make a good fit.
Way to go ! Yep, when you have the control and sharp to take the thin ones one can still take off more. I love sharp tools. Thanks for helping making the videosrocGive me six hours to chop down a tree and I will spend the first four sharpening the axe. Abraham Lincoln ( 54° shaves )
Yes, a thousandth of an inch or two can make a big difference fitting joints. BUT, that no way implies a need to be able to measure the joint parts. You gauge the fit by how the parts fit, unless we are talking about industrial production.
Oh yah naturally. Any thou talk on my part usually refers to error in tools that I am COMPARING. Attempting to demonstrate where the drop off in quality of RESULTS lie. I don't measure my dovetails. Never said I did.One thing I said was that we squint at light under a straight edge and that gap/light is often less than a thou. Not that we need to eliminate that gap. A two thou error in a straight edge how ever can result in a four thou error in an edge joint and that on occasion with thick stock can show a gap when glued up. and so it goes . . .rocGive me six hours to chop down a tree and I will spend the first four sharpening the axe.
