There's lots of milling required with this piece, I did notice that the IR lamp arm is tapered in depth being shorter on the right than the left ( as you look at the vehicle from the front) this I believe would have shed any rain water away from the canvas opening.

Thanks Oliver, I have now finished the IR lamp bracket and I've ordered the aluminum bar so I can turn the lamp it's self, it is just about as big as I can handle on my lathe .

Hi Phil,
Lovely fabrication work on the bracket. It's great to see these parts being made up in steel and operational as well.

Have been looking forward to seeing how you planned on tackling the IR spotlight. Thought you might go the 3d printed route, a la Stephen White.
Watching with great interest.
