Today I finished up work on R2's side vents.
I painted the back plate the day before and it was set to go.
Here's I have lined up the plates and clamped them together.  
As I did with my previous set, I used JB Weld to bond the pieces together.  Since there isn't a lot of area to apply epoxy too, I made sure the sides were lined up and applied it in the seams
After this dries overnight, I'll use silicone to attach a piece of steel sheet metal to the back.  This will allow for a magnet mounted in the frame to hold it in place.
