I installed the WSM fan adaptor and the lamp rods tonight. It did not go quite as I had planned.
I intended to drill the holes for the lamp rods on the opposite side of the bracket screws next to the door. I guess I wasn't paying as close attention as I should have been, because I ended up drilling the hole on the back side (opposite the door).
At first I was bummed. I actually heard myself mutter "measure twice and drill once". I thought about it for a bit. You know the "how the hell do I fix this" conversation you have with yourself after you realize you made a mistake. The more I thought about it the better I liked it. I'm the type of guy that snags or trips over everything. I bought 8 foot leads. With the leads running to the back side of the smoker, I'll probably never snag them. Accidental genius, that’s what that is! My wife, knowing me for the klutz that I am, agreed whole heartedly.
You can see the lamp rods on the opposite side in this picture.
I drilled a hole for the BBQ Guru WSM fan adaptor to the right of what will now be the front vent. The adaptor directions said 1" and the holes in the WSM are 3/4". Split the difference and you get 7/8", which is convenient because the largest size on the small bit is 7/8". I would have had to switch to the large bit if I wanted 1". I can always enlarge it to 1" later if I want. I used masking tape and a 1/8" bit to drill a pilot hold. I did not have any problems with chipping the paint.
And here is adaptor with the plug installed.
I am looking forward to a spare rib and thighs smoke this weekend. I really don't need it for that short of a cook, but it will give me a chance to play with it.
