I am designing a table lamp that is built as a four sided column or
box but I want it to taper from bottom to top. I'm sure I can do some
3D CAD and figure out the miter but wasn't there a table or formula
somewhere that provides the miter angle.
I know it will change very little. I am doing a 4 sided box that will
taper at maybe 5 or 10 degrees. I think the 45 miter cut will actually
change by a degeree or less but I would like to get it precise for a
clean fit up.

The other guys have the correct answer but I don't typically get that
precise. I am more interested if it is a few degrees off. I always do
test cuts on this type of stuff so if I see 44.333 degrees, I know I
need to start cheating towards 44 to get a sweet fit up.

You might think so but it isn't true.

15 1/2 degrees should be close enough.

$30 Electronic Tilt Box. Works in 1/10's of a degree.
Or if you have an accurate miter gauge you cut a scrap triangle to that
angle and use it to adjust the tilt on your blade.

LeeValley has the answer. This is one way to do it-

I have it and it works well.

I like that!
I'll be putting that on my LV list
Thanks

Yup, center lines of the tails and pins should be level if you
want them to look right. Build a quick full scale model and
pencil the joints on, then copy when all looks right. Cardboard
and paper packing tape are your friends.

Here's one. http://jansson.us/jcompound.html
There are many on the web, just google
"compound miter"

Perhaps I'm missing something here... but why could you not build it as a
*straight* column (eliminating any issues with compound miters), then taper it
after it's built?

Look for this and get it at 1/2 the price.

There's also a protractor that uses the same principle:
http://www.wixey.com/digitalprotractor/index.html
For setting your miter gauge.
I've got both and they're great. But be warned that the protractor,
regardless of what the ads say, cannot be locked down. It can be
tightened to where it won't flop around, but in appreciable pressure will
move it. I checked with the company and they confirmed that, but their
ads still say otherwise.

I got this one, the protractor, and it works well. I used to
physically match angles, then tried a regular t-bevel, but this is
even easier and much more precise. I can transfer numbers to the miter
saw from it, not just physical angles. (and it's only 1/2 the cost of
the tiltmeter.) I ordered it during one of the free shipping sales.

There are other times when you might want to show the rays from qtr sawn
oak, and you might do the miter for that purpose.
So there are reasons. Not sure thick wood is a good one. I just glue up
what I need to the desired thickness if I don't have wood that size.
Gluing up has been done for a long time.

Just a curious question, but how does one set a
blade angle of something like 15.6 or some of the
other very precise angles required in these calculations.
I have some very accurate setting tools but none would
allow a blade angle that fine.
Having never built anything with a compound angle, I'm
really curious.

44.8 degrees for a 5 degree taper, 44.1 for a 10 degree.
