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 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.

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
