Magnetic clamp-on drillpress. Any steel erector will have one, or you
can hire them.

Or a plasma cutter. Or an oxy-acetylene cutter.

Or a _SLOW_ heavyweight handheld drill, like the one I use for timber
framing. A normal drill would do it too (1" isn't really big), but if
it snatches it'll have your wrist off. You might borrow such a drill
from a plasterer, as they're most commonly used for mixing.

You could even do it by hand. It's not that big a hole.

Mark the circle, then drill multiple holes around the circumference
with a small drill. Knock out centre. File smooth.

Nah, DIMM would have insisted the OP drill 2 x 0.7" holes in case one
failed.... a "win win situation".

If it is mild steel then use a tubular hss core drill, made by starrett and
others. screfix sell them too. if it is hardened then you need flame or
spark erosion or plasma.

Drill press / slow speed / 1" blacksmiths drill and cutting fluid .. would
help to pilot hole with a smaller bit to start

http://www.dm-tools.co.uk

and search for FAIBSD1

1 inch hole isn't big ..... ;-) ...

Whenever one drills metal with whatever size bits the one thing to remember
is to use a cutting fluid. The rate of cut, even with a drill running at low
speed, far exceeds that of a drill used dry. You will also extend the life
of the drill bit by a fair margin because it will cut properly instead of
skidding round and wearing it's way through. It is very satisfying to see
two spirals of swarf formed by a properly set up drill.

As MM says, mark out a circle and drill holes around that, possibly
using 1/8" first then 3/16 to join ring of holes. Knock out the
centre, clean with 1/2 found file until your tow hook fits.


How do I tell if its hardened without buying a drill and blunting
it ?

I doubt it will be hard, although the cutting edge of the bucket
may be hard on one face. Test it by trying to scratch it with a
bit or a file. If it will scratch (is not "file hard"), you can
drill it.

The core drill sounds like what I need.

Hmm.

Try a small, cheap (expendable) drill

Whatever, you need to run it at the appropriate rim speed, or you will
RAPIDLY blunt the saw.
A normal mains drill will be a bit fast.

Personally, I'd get a 10mm bit, and drill a ring of holes.

How heavy is the trailer? If it's not too heavy, could you rig up some way
of *clamping* a towball onto the edge of the bucket (maybe bolting it onto a
dropper plate first to give more area) rather than having to drill the
bucket?

You'll also need the power drill to go with it. And they're not cheap.

Its a 1 tonne max load in the trailer. In the US you can get tow balls
which sit on a spike, so a single hole in the bucket lets me bolt and
unbolt the ball. I don't want it permanent as it gets in the way for
digging. The trailer was fine on the 4x4 but I traded that in for the
bobcat and a 206. The 206 won't tow the trailer up the track, you
loose traction. If I don't do a decent job the trailer will suffer
more damage.

Right now I leave the car down the road in the village, and bobcat up
the track and down into the village to empty the trailer.

Hacksaw will make short work of joining the holes.

Multiple holes, very close together. What is holding it in after that?
Effectively, swarf, and not much else.

You need a certain hole spacing if you're drilling it freehand (or
else you'll run holes into each other and leave a gap) - and if you
have a drill press, just drill the hole anyway.

Knocking these webs out with a skinny chisel gets a bit tiresome in
over 1/4" plate. There's no room to work in the hole, and the plate is
to thick to allow the slug to bend over and give you more space.
