WOW. A few thousandths ! ! !
I'm a Master Tool and Die Maker with over 50 years experience.
I normally work with tolerances of 1/10th of a thousandth, sometimes tighter.
My gage blocks are accurate to a few millionths of an inch.
I'm also moderator of the Metrology section of the Practical Machinist forum.
That's the largest forum for machinists in the world.
I don't do woodwork.
