Some progress. Here are the two aluminum angles mounted in the fixture:
And then I lay the three heatsinks on top to figure out spacing and where to drill my mounting holes:
Now because of the shape of the housing the aluminum angle had to be mounted pretty much flush with the bottom of the housing but I need clearance for the LEDs and optics so the heatsinks have to be raised a bit. So I cut some nylon spacers to place between the heatsinks and the angle.
And here it is all assembled:
So now that the mechanical engineering part is more or less sorted its on to the electrical engineering
