I know that there has been may different discussions on LJ’s over the years with regard to accuracy and tolerances in WW, especially with machine setup. Here’s an interesting video by Bridge City Tools that demonstrates the difference of just a few thousands of an inch in joint tightness:

For the record, I’d like my joints to look like the last example but most days they look like the first….

I do machine work and know the difference between a good fit and a bad fit. For those without any metal working background, it’s easy for them to downplay the need for accuracy. I try to do my wood working with machine accuracy. I know that wood is fickle and will change dimensions with humidity, but if my tolerances are tight, any changes due to humidity will be much less than the 1/32” tolerances that many are content with. I always advocate working to as close a tolerance as possible. At least Bridge City Tools recognizes the need for accuracy.

If asked why I work to such close tolerances, my answer is “because I can”.

Accuracy and repeatability require discipline.
It is reflected in your wood work.

I do work with close tolerances, and having several years in the machine trades, I appreciate the desire to work to reasonable dimensioning. Calipers and micrometers do have a place in my WWing shop, but I’m not gonna go nutso about thousandths of a dimension
Bridge City makes some excellent tools. Just too expensive for my projects.
I prefer to spend my bucks and time with well adjusted machines and good blades on all tooling.
BTW (Charles Neil quote:) foul language is often used sans guests. :)
