As I mentioned in a previous post, I have too many big logs. I want to
use some of them to make a water fountain stand at my summer camp. To
do this I want to bore a hole approx 12" in diam and 14" deep into the
end grain of a big log.
Does anyone know of any tools or techniques to achive this? I am
trying to build a rotating chainsaw bar, but so far it has been
proving a bit complex for my simple metal shop.
Thanks.

Horizontal boring mill. I've seen them on eBay for less than $20,000.

How about a 12" circle template and a plunge router with a 14" straight bit?

Draw a circle on the end, take any 14" long drill bit you can find,
whatever kind is cheapest or available, and drill out a circle of
holes inside the drawn circle, and chisel out the rest. Same advice
as others but without anything fancier than a cheap old drill. Keep
in mind the width of the bit will be inversely proportional to the
number of holes you'll have to drill to complete the circle.

You need access to a milling machine or a gun lathe.
Think this operation is what at one time known as trepanning and is
performed in a horizontal manner.
The easiest way would probably be to clamp the work and use the power head
to turn the cutting tool.
Considering the depth, may need to mount the work on a sled to handle the
movement of the piece into the cutter rather than move the cutter.
You definitely need some major equipment to do this task.

You can never have too many logs.
Don't see why you'd need a hole that size, but also don't see why
you don't try to keep it simple If I wanted to do that, I might just
stab a chainsaw in, with several repeat cuts, and make a rough circle.
Then hack it out with chisels. Or, get the largest bit I could find,
and drill a batch of holes, and then use a chisel. Or, you could always
use a section of pipe, set it on the end, and put burning charcoal in
the pipe, and let it burn down. Or, if you had lots of time, maybe you
could train termites to eat just the part you wanted. Or, you might be
able to use a power post hold digger, don't really know how one of those
would work on wood, but they seem to work OK in clay. Or, just make a
large boring bit, and use it. Or, you could alway cut it off, then in
half, and gouge out the center, and join them again. Myriads of ways to
do it. Now that I think on it, I probably wouldn't do it at all.

Scorp.
I would use a router and a circular template or circle cutting guide
and cut out a 2" deep circle to define your space. That's about as
deep as you can safely go with a router (some bits may get you a
little deeper, but it's no matter). Then I'd use a hatchet and
chainsaw to remove what's inside the circle, going deeper and deeper.
Stay clear of the walls, which you can rough out with a chisel if you
want to keep the diameter consistent with the circle you defined with
the router.
Good question. Timberframers or boatbuilders probably have a better
way.

I already gave one option, but I thought of another.
This one involves glueups but makes the cutting much easier.
1) Crosscut the log at 14"
2) Crosscut that piece again at 7", leaving you with two 7" pieces.
3) Scribe your circle on the top of the top piece
4) Cut each 7" piece in half across the diameter (now you have four
half-circles of 7" thickness each)
4) Bandsaw out the circle on the top piece (Note: if you don't have a
bandsaw or one that will go 7", then cut 3 or 4 smaller cutoffs
instead of just two, and cut out the circles using a smaller bandsaw,
jigsaw, Sawzall, bowsaw, or what have you)
5) Glue and clamp the top two pieces back together
6) Clamp the bottom two pieces together, but do not glue. Place the
glued top piece in proper location on the bottom piece, and scribe a
circle in the bottom piece based on the top piece hole
7) Cut out the hole of the bottom piece and glue up as per #5
8) Bore matching holes between the bottom piece and the log
underneath, and between the two pieces, make dowels to fit the holes,
and glue up all pieces back in thier original formation.
If you make your cuts neatly and are careful with the glue-up, no one
should notice that it's been dissected.

I saw a HUGE lathe used to produce parts for an OTIS elevator a long
time back in a newsreel. Handling a 12"+ diam log would be trivial.
You couldn't afford the shop space I'd think.
Dan.
LOL! Best one I've seen today.

You might find a circle cutter large enough to do the outline, I'd consider
buying or renting a power gouge like those used by log home builders to
"dig" it out.

How about a large spoon bit and a LARGE drill...Hmmmm Maybe even a gas
powered post hole digger. ;-)

A really big lathe and a boring bar?
Drill a pilot hole, thread a bandsaw blade through it, and re-weld the
blade?
Borrow some big chisels from a timber framer and go at it with a mallet?
