Before you drill your side holes, make sure you've got the appropriate hardware lined up first. My plan was to use 1 1/4-inch black pipe, then use fittings that would snug up, airtight, to the inner and outer walls. Simple, right? Well, black pipe's diameter is smaller at the ends, so it only threads on so far. So the simple solution was to add washers, right? Wrong, I couldn't find washers big enough to fit on the pipe, so the fabricator has to make me some.
Yes, our projects are progressing similarly. But I'll be stalled for a while, until the welder gets done with some stuff.
Keep up the good work. Don't let The Warden get too much supervision on your project!
