Here's a neat tip for squaring the drill press table-

In a machine shop on any machine with a head stock ( or table)  that can be tilted  that's a regular operation. It's called "tramming the head."

All one needs is a little test indicator and a bent hunk of 1/4"  round steel.

Actually, I've been using a bent piece of clothes hanger.

Or a Wixey will do the same thing. I put a solid piece in the drill press and the magnets will stick so you can zero it. Then put it on the table and adjust to it is 90 degrees.

 

 

I've done this, too, John.

I am with Cliff and Lew . Do not need the high tech

I've always used the bent rod too.  I guess you could get it perfect with their set up.

Last week, I spent some time going through some old magazines from the '90s.  Especially amused by the shop tips each issue.  Two things:

1. Didn't every one know that?

2. Same old contributors every issue.   One that I always chuckle over is a guy from my little home town.   Think he spends all his time tinkering and not much time building.

A great idea...I like using a straight rod and a square.  If the square is good enough for my other tools, it's good enough for the drill press.  (Otherwise the other tools would get "square-envy")
