I have some 1/2 inch metal I need to make some large holes in (about 1
inch). This is to put on our tractor tiller to make it set back farther
from the tractor tire.

All I have is an a/c welder and a cutting torch with small tip. What
would be the best way to do this?

A 1" hole is a bit small to blow into 1/2" stock with a torch. I don't do
arc welding stuff so I can't answer to that.
Personally, I'd drill the hole to as large as I can hold and then grind from
there with a carbid burr if the steel is not hardened.

A QUICK way would be to get a box of gouging carbons, and blow a hole
through with the buzz-box. It's rough, but fast'n'nasty.

Ummmm, also, if you just can't find gouging carbons, set your buzz-box amps
up high, put a goodly fat welding rod in your clamp and just hold an arc in
one spot for a while.

Ironworker, drill press, milling machine .. however, if all you have is
a cutting torch, why even ask? Burn the holes and you're done! - GWE

Yep. you may want to drill a small hole (1/4" or so) as a starter and
use a template (probably about 1-3/8" in diameter) to guide the cutting
head.

Chisle, hammer, and some files?

Maybe you can avoid the drilling altogether. You say you want to move the
tractor tiller back. This must mean that it is now bolted on through some
1" holes that are too close. Why not cut the plate with the holes off, and
weld in an extender plate?

Works best if you can use your air hose and a fine spray nozzle on the
puddle. Get the arc going and spray the metal away. You can actually
cut pretty close to a line this way.

Downside is the HAZ (heat affected zone) makes any machining
operations a bitch after doing this, unless you anneal the area.

But you can indeed blow a nice big hole, fairly neatly with a welder,
some big rod and an air hose

Another possibility if you need a nice round hole is to find some
holes, cut them out with your cutting torch, cut a hole where you want
the nice hole, and weld in the nice hole. Something on the order of
how Ernie puts square holes in the anvils he makes.

This week I did something close. The school needed a handle for a
faucet. A normal faucet handle would not work as the stem is sunk in
so as to prevent Vandals and Goths from using a Crescent wrench. So I
bought a 1/4 inch drive socket at St. Vincent de Paul for $.15 and
silver brazed it onto a tee handle.
