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
Again, all tools can be found at Techshop (in case you're not familiar with "center punch" or "Rite Hite clamps.")
- 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
- Tape Measure
- Wrench and Rite Hite clamps for holding work.
