I have measured some stringers and sheeting to higher accuracy than 3.5 thou and 7 thou.
One thou is 1/1000 of an inch.

Just measured a new sheet of semi-hard balsa labelled 3/16 x 2 x 36 inches.
The thickness varies from min of 0.187 to max of 0.189 inch .
So this sheet varies by 0.002 inch ( 0.0508 mm )
3/16 inch is 0.1875 inch

Sure: you can measure to that kind of accuracy. But can you cut to that accuracy?
I bet not many can. People cut until they are pretty close and then sand the last 0.05 to 0.2 mm to fit, regardless of whether the wood is just right or some fraction of inch or mm off.
We do not have to cut to that accuracy.
In fact we should not.
We should not cut "pretty close" . . . we should cut a bit longer.
As you meant I think; we measure, cut a bit longer and sand to fit.
We are saying the same thing so I do not know why the question
can you cut to that accuracy?
The sanding is part of the cutting process to fit so YES I can cut to that accuracy and YOU can also.
I thought it was evident that my original posting was referring to thickness of stringers and sheets.
In fact I wrote "the thickness varies"
Have a nice 2011.
