What would the value of the integral over (-infinity, infinity) of
1/(1+x^2) dx look like if you didn't express it as the Greek letter PI????
Even being in error by the amount above would make it that you bought it
from Kmart--apologies to Kmart (and/or the Sears Holding Co.).
I wasn't replying to your post specifically. I just wanted to get in my
2-cents about accuracy. As far as computers go, integers can match
exactly, but not numbers with decimal points, in general. You can ask
and get exactly 3 twobyfours, but not of any exact dimension! ; ) Of
course, the value of PI can be matched exactly--just not by a typical
computer. If one is willing to express numbers with base PI instead of
base 10 or base 2, then all bets are off.
.7 can't be stored exactly as such as a floating point number on a
typical modern computer.
Someone "casted" the number to an integer, losing what what stored as a
They used: (int)(average)
when they should have used: (int)(average+.5).
The latter would have rounded.
_I_ can, with woodworking tools. I built period reproductions of French
Revival decorative furniture for about 20 years.
Except for a table saw, most of it with hand tools, per the authentic
methods. Doing fit-ups to a thousanth is a must if joints were to be
perfect. (and yes, I know about the growth of the wood, but some joints
demand that precision)
No metal fasteners in them, either. Gauche'.
I can do dovetails you can't see a gap in by hand, too. Can you? I

I suppose that means that you used the authentic methods when it
suited you. It really does not matter what tool you use, it is the
result that counts.
I use metal fasteners for knobs, and hinges and attaching adjustable
feet on furniture that I design and build, that is about it.
Probably not, but with a router absolutely.
While we are bragging,
And with the exception of a couple of older pieces I have built all of
these in the last three years and after I converted to Sketchup.
AFWIW all joint details were drawn in Sketchup.
Hi Leon. Got a question about Mary's bookcase. I can't tell from the
pictures presented. In the back of the bookcase, I see you've put in
columns in the centre of the shelving.
Are they inset into the shelving or is the shelving have a space
behind it the full length of the shelving?
Hope I made my question clear.

The back of the cabinets have face frames also. The back face frames
however are assembled with lap joints that join with the rabbets on the
inside edges. The center back stiles are part of the back face frame
and it too has rabbets. The rabbets are 1/2" deep and 1/2" wide. The
back panels fit in to the rabbets from the back side.
Soooooo the shelves have a straight back edge that butts up against the
outer and center stiles of the back face frames and there is a 1/2" gap
between the panels and the back edge of the shelves.
Clear as mud? LOL
If you are using Sketchup I can send you a drawing for to look at more
