Step 3: Reflectors

Picture of Reflectors
First I cut the aluminum bar into two 12" lengths. Then I sanded one side fairly smooth with some 400 grit emery paper, and buffed it to a mirror polish with some tripoli compound. Next i sanded the last inch on each end to a rough finish, as well as a spot in the center, to give a good bond for epoxy.

On the tubes, which have square end caps, i touched one face of each end with a drum sander, leaving the acrylic very rough, and taking the material down almost flush with the tube.

Then I just glued the tubes to the reflectors with some thirty minute epoxy, putting a dab in the center to back up the tube.
