How to Make Steel Corner Brackets

Featured
Picture of How to Make Steel Corner Brackets
This instructable will walk you through how to make your own angle corner brackets out of steel. They're great for building or strengthening  shelves and table tops; handy if you need something custom; and anyway much cooler (and more available) than the stuff you have to rifle through at the hardware store.

I made these brackets from my own scrap material using the tools at Techshop Detroit (www.techshop.ws)!

P.S. I made these brackets using safe, one-off, garage-shop style procedures. Incorporating jigs, fine-tuned fixtures, and calibrated materials would increase accuracy and efficiency for production. RULE OF THUMB: "Making more than 3? Make a jig for it!"

P.P.S. This is a great example: Drill press repeat drill fence fixture

Step 1: Tools and Materials

Picture of Tools and Materials
This photo features all the tools and materials I used to make the brackets for this instructable. Some tools will be featured in operations that I walk through in other instructables (want to make sure you're using everything properly and safely!)

Again, all tools can be found at Techshop (in case you're not familiar with "center punch" or "Rite Hite clamps.")

Top

- Ruler/straight edge. Get a good steel one, aluminum ones bend, ding, and can even get whittled down accidentally by sharp marking tools.

L to R:

- Scrap angle iron (go for 1/8" thick or more, with sides that are 1" or wider)

- Fine point permanent marker

- Center punch

- Drill bit - one from the hardware store is fine for steel - make sure it's a little bigger than the screws you're using to install the brackets

- Square

- Tape Measure

- Wrench and Rite Hite clamps for holding work.

Nicely done. Good emphasis on safety. I volunteer as an EMT, and I've taken a few guys to the hospital who didn't clamp down a piece that they were working on. One positive comment. You can save some time/frustration, by drilling all of the holes before you cut the individual pieces on your saw.
Great photos!

The way this is usually done is to fixture the parts, then drill each hole, loading and unloading the parts. Saves a lot of measuring and punching. It is far more accurate too.
