Keep in mind..... .0015 can make a difference in metal working.......working in woodworking to 1/650 the of an inch is pretty unrealistic. I'd not worry about that. I'm usually pretty happy if things are within 1/64th. Wood expands and shrinks....whats perfect today won't be tomorrow.

Read this and memorize it. Woodworking CANNOT make use of those kind of tolerances!!! If you think it can you are only fooling yourself.

I do not even try for 1/64 inch. I am perfectly happy with 1/32" for the vast majority of projects.
