If you have a disk sander with a tilting table, I'd use it and a home
made circle sanding jig..
I use 1/2" shank router bits in a drill press and I don't think I'd
try that heavy a cut on it..
Slanted jig for the router, spiral bit. Two pins to reference, in the
board, router screwed to a base. That, or tilted bandsaw / disk sander
with circle jig.

MLCS and others have 'em, but won't make as smooth a cut as a spiral on a
jig, especially uphill. A bit tougher on the router, swinging a 2 1/2" wing
bit, too.

Oh, for goodness' sake! What a lot of trouble to go to! Why not just buy a
45-deg chamfer router bit with a longer cutting edge? Simple, quick, and easy.

Well, no, he hadn't, or at least if he had it wasn't evident in his post.

You haven't looked very hard, then.
I already posted links yesterday, to 45-degree chamfer bits with 1 1/4"
cutting lengths, one at Rockler and one at Woodcraft. Didn't take me more than
two or three minutes to find them.
Google on "45 chamfer router bit" and you'll find a lot more.

1 1/2 inch diameter and then, only if it comes to a sharp point.

Thank you Doug. I was reading through the whole thread before beginning a
reply and the very thought that kept haunting me was "is this the Rube
Goldberg newsgroup?". It was worth a good chuckle to see how complex the
suggestions were becoming.

I think he's trying to do this on a curved (circular in fact) stock.
So the tablesaw won't work(*). Even using a plane or spokeshave will
be a little tricky with the change from long to end grain.
The ideal way to do this would be to put the stock in a bowl-turning
lathe, and cut the chamfer with a skew.
I think the idea of using a long straight bit, and either tilting
the router or the stock sounds most likely to work, assuming there's
no lathe available.

(* I suspose you could pin the stock to a sled, and somehow spin
it round thru the sawblade...)

Yeah, that would work...but calculating in my head, a 3/4" chamfer
is going to result in a cut length of around 1.1". So if anyone
ever needs a slightly larger chamfer (or one that's not 45 degrees,
for that matter), some of the ideas in this thread could be of
value :-)

Because he's already thought of that.
Secondly, 3/4" is a big chamfer. Biggest cutter I can find is only
18mm

I did not read the entire thread either, but tonight I saw that Ridge
Carbide makes a cutter that is 1 3/4". If the other link does not turn out,
check with Ridge.

That's too big for a router. You'd need an enormous bit, and a very
well setup table. You could do this in a spindle moulder / shaper,
because they use a bigger diameter cutter.
The problem with routing a chamfer that size is that it will be
impossible to control the cutter's depth of cut to better than a small
fraction of the cutter diameter. With such a big cutter, that's an
appreciable wobble. You could certainly cut it (given a large enough
bit), but the finished surfae would be anything but flat. If you go
for it, stop early and hand plane the last pass.
My favoured approach for this would be the table saw. If I didn't
have a table saw, I'd hand plane it. If you have a smaller router,
then you could hog off much of the timber first.

Yes, I'd missed that bit.
Then it sounds like a job for a router, mounted on a trammel. Use an
extra- long straight bit (used by kitchen fitters to joint worktops -
they're worth having) and make the router sled with a built-in 45°
angle.
If you're hand planing something like this, I'd make a croze for it -
a barrel-maker's plane, with a custom-made one-radius sole. It's
soemthing to do with all the Stanley irons I have spare from upgraded
bench planes.

If you want to cut a 3/4" deep chamfer at 45 degrees, you need a bit that's at
least 3/4" in diameter. (At a 45-degree angle, the horizontal and vertical
distances are the same.)
