drilling square holes
you guys might have seen this...but it got me all giddy just watching
TOOL HEADS !!! (it's like a gear head but with tools) PAY ATTENTION.
how many times have you needed a square hole and had to drill it out and then work with a file to square it up..... the japanese (those crafty devils) have solved your problem...this is just too dang cool (and expensive probably)
How the Hell Can This Magical Square Hole Drilling Machine Work?

That's pretty cool. I suppose the bit is free as long as you purchase thier special press for a 100 g's. I had to do the round hole small file for the carriage bolts for the rear floor section of my panel. Drilling those in a hand held drill would have been like a ride in an amusement park,lol. Nice link and amazing what man can develope isn't it. Thanks John

Easy, a kid that loved spirograph ( Spirograph - Wikipedia, the free encyclopedia ) grew up to be a machinist.

These similar mortisers have been used in the woodworking industry for years. Never thought of using it on steel.

I bought a roper whitney punch press at the swapmeet for $25 and you can buy dies for square holes. The pic isn't mine, mine is a little bigger and has the ratchet arm addition.
A smaller version then mine, but it shows how it works.
