New Member-Drilling Square Holes in Metal

Hi, my name is Bud Buchanan, Townsend, TN in Smokey Mtns. I found this site about a month ago I guess, and have found much help. I am mostly a DIY'er, because I can't afford to buy the tools I need. I am 73 yrs. old on a set income and don't plan on using tools to go into business, just fix things around the house. At present I am working at building a Pedal Steel Guitar that has 5/16" square shafts for the bell cranks. I need to drill a bunch of square holes, so I need help. Thanks to those who post new "homemade tools" and those that run this website. Good Luck to all....Bud

Hi budbuc - welcome to HomemadeTools.net :welcome:

Post some pics of the pedal steel guitar if you have any, I'm sure people would like to take a look.

For the square hole job, I would suggest posting a new discussion in the Tools in Progress subforum (or click "Build Help" above), and I'm sure you'll get some good ideas.

Looks like you didn't have to wait long! Frank S to the rescue: https://www.homemadetools.net/forum/...e-broach-40067

Hi Bud,

Welcome! :welcome:

Do you play the pedal steel, too? I've always liked that instrument. :)

What's next up on your build list?

Hi
Fileing a square hole is a steel boss probably isn't as bad as you might think. The key is GOOD Sharp (read new) files. Old dull files are frustrating at best.
This is a great exercise in craftsmanship. First, with a new file, cut on only the push stroke, then lift and repeat. after a few strokes remove the file from the work and brush it clean with your hand or better yet a file card following the direction of the teeth. then proceed patiently and carefully. with good tools and some practice you can file way more than you ever thought you could.
