Fine Woodworking has an article about cove cutting on tablesaws in the
current issue. The article mentions that the spreadsheet will be
available online.
On the FWW site, there's no sheet to download, as they say the macros
will set off virus protection on some computers. It looks like
someone rewrote the thing in Java or some other language that will run
online. I really wanted the sheet, as I use a PDA in the shop that
isn't connected, so I emailed FWW and asked for the formulae to make
my own spreadsheet. I have this kick ass shop spreadsheet that
includes my cut list generator, Cape Cod Bob's shellac sheet, some
miter calculators, it's really handy. The cove calculator would have
fit into it well.
The response was "The author dosen't want to make the data public".
I can fully respect that, maybe the guy wants to sell it as a stand
alone app? No problem there.
Why not simply SAY THAT on the site? <G>

That Phantom guy sure is pretty smart.......:-)

Go to the page where the applet is running, right-click on the screen and
select View Source. That will give you some clues as to the formula. You
can save it to a file for viewing offline also.

Right after I posted the original message, I realized that the applet
was written in JavaScript, which is uncompiled, and did exactly as you
suggest.

here's a downloadable cove calculator you could use offline:

(it's one of the programs in the list)

Doesn't save the graphics or buttons, however. The calculator popup
is supplied by an ASP script. Saving the page results in missing
graphics. Oh, Look! There is a standalone post in A.B.P.W.

sheeeesh....there's just no pleasing some wooddorkers.
Live with it......;-)

Actually, it all can be done with Trig functions, which can be put into an
Excel worksheet. I roughly worked out the functions when driving to work this
morning. I suppose I could take 15 minutes to work them out completely and
post them here. Now if I can just get a spare 15 minutes.

Okay.... I'll give you 10 minutes.... anyone got a spare 5 minutes they can
donate to David?

OK, OK...here's what I've got.
Assuming a 10" diameter blade with an 1/8" kerf...
H=height of the cove and height of the blade.
W= the width of the cove
a=the angle of the fence. 0° is the fence perpendicular to the sawblade. 90°
would be the fence in a normal rip cut position.
W=2*sqrt(10H-H*H)*cos(a)+0.125*sin(a)
My math skills are not up to solving for "a", so that you could plug in the
desired height and width of the cove and get the angle. (What do you want, I'm
a three time community college drop out.) But, you can put the formula into a
spreadsheet where one column has angles increasing by one degree increments
from 0° to 90°, and the next column has the formula with "H" as a constant
reference to a cell where you input the height and "a" as the angle on the same
line. This way, you could see for any given blade height what the cove width
would be for any given angle.
Anybody still with me?

Me too.
I have always "snuck up" on that type of cut. I have to do this for a piece
of crown this weekend. I'll do the imperical test.

Never got the chance to test it, got tied up working on a window seat
/ shelving unit. Not to mention two hockey games, a 7:05'er on
Saturday night and a 4:05'er today. I'll do my best to try it this
week.
I'd like to use some custom cove molding on the shelving unit, so
we'll see how it goes.
