Ever wind yourself up in the electric drill when drilling a big (over
1/2") hole in metal? I sure did when I had to drill out some 5/8" holes
out to 3/4" in the underside of my broken tractor.


I wrote to HSM in 1996 and asked for ideas. I got a lot of feedback so
Here's a new page on my website that summarizes the responses I got:

Some decent ideas, but not too many that would be useful for your actual
problem of opening up an existing 5/8" to 3/4"... If your existing was 3/8"
or something similar, the job is actually easier IMHO.
