Phazeshyft:where did you get the instructions for that housing.
Here is the website.

You have to apply to join, really just a formality, and then the guy who's site it is (a member of this board, name is PadiPro) will approve you, and then you will be able to view the website. You have to go to the documents tab on the left side of the screen, and when you click it you will be able to access the plans for the housing. It's all simpler than it sounds. There are also excellent plans there for a DIY canister light. If you have any questions or need some help, feel free to pm me. It's really easy - in fact, I'm already starting to plan for another one with some variations. Good Luck!
