I am making some aluminum bracket shoes. I thought I would share a few images.

Nice ! You doing CNC with bar stock....or ?
RioStat- Yes, It is much easier to run parts from a bar. It saves time and the number of times you need to handle the parts. Also with 8 parts at a time, I can do other things while the parts are running. If I run one at a time , I need to stand at the machine and change parts every minute or so.

I like the oval hole.
Helix- "I like the oval hole."
Thanks. Next I will give them a light tumble deburr and then send them out for anodizing. For this build I will black anodize them. Maybe on the next build I will go red.
Beautiful! The perfect use for a CNC router!
Just curious—how are you threading the holes for the mounting bolts? And what is the purpose of the oval holes in the upper face?
Ken LeVan- I ran these on a CNC vertical machining center. It has rigid tapping, I program a G84 with the 'Z' depth and a feed rate (the distance of one thread pitch X RPM). I hold the tap in a rigid collet holder. The machine will feed it precisely to get accurate threads.
In the attached image there are no tools in the tool holder. It holds 20 tools and does chip to chip tool changes in under 1 second.
The oval pocket is to reduce weight and add some visual interest.
Many people have written about powder coating of hardware. It's too "chippy."
The anodizing is the perfect application of Aluminum I M HUMble O.

Quite a piece of equipment!
Yep
