Anodizing can be done in your shop/at home. Pretty simple to do, just takes some water bath containers (ice bath & acid bath), car battery charger, battery (sulfuric) acid, lead probe and misc. I did this in 2001 for a small sized QCTP for a minilathe I had at the time (there weren't any smaller than AXA available at the time). Used 7075 T6 Alum., machined the parts on a minimill and did the anodizing in my driveway. Used Rit black dye for the color. To seal the pores to trap the dye, the anodized, dyed parts are boiled in water as the last step. Found instructions online but haven't looked recently. Only real issue was disposing of the acid afterward, but there are places/ways to do that.
I also did it with some specialty brackets I made for a surveying project, mounting a water velocity reading meter on the surveyor's prism rod for recording locations of water velocity readings as input to a digital elevation model as part of 3D hydraulic modeling of fish habitat.
