Yes, i made the brackets.
I bought a half finished cnc mini mill of ebay which was supposed to be running, but it was a clunker, so i've rebuilt it completely using ball nuts and shafts on all 3 axis, decent stepper motors and built myself a driver and controller cabinet.
It now runs off Mach3 control software, and i use some programs from Vectric, Cut2D, and Cut3D to create the g-code that Mach 3 needs to control the steppers.
Been a great learning curve.
Now that i have the bug, i want a bigger decent mill like Aussie Mikes to convert.
This is one of the canister brackets i milled up.
The machine cuts particularly well with smaller bits upto about 10mm diameter, but starts too load a bit with anything bigger unless i reduce the cut pass depth.
I dont have a cutting fluid feed at the moment, so i use crc or wd40 spray periodically.
This is the finish off the mill, super smooth, but you can see tool swirl paths.
This is what they look like after 24 hours in a vibratory tumbler, i bought this off ebay as well, jewlers use them for polishing, but the trick has been to find media that will smooth and polish the surface.
I've found little 8mm ceramic pyrimids work great at smoothing edges and polishing aluminium with only a cleanup with brasso needed to make them shine.
You can see my chassis tube brackets in this pic on the left as well.
This is the
Oil Cooler bracket (mild steel) welded to the front of the chassis, also off the mill.
This is the top plate to the original cooler shroud i made, but i ended up simplifying the design.
The part was longer than the mill, so i had to flip it during cutting, on the first pass, i drilled 2 small holes and some pins to use as alignment when i flipped it over.
