Not sure why I was thinking the joists were perpendicular... they're parallel to how the wall will go. Luckily, a joist runs right down the line (about an inch off of the original plan) where I want the wall.
One thing that I know I need to do is to check the insulation in the attic above the garage. It doesn't get as hot in there as our last house that had ZERO insulation in the garage but it definitely gets warm in the summer. Winter doesn't seem to be much of an issue, though. Can I just put batting above the room or am I much better off paying to have insulation blown in if necessary?
Thanks! I find this very enjoyable, as well. It's been a long time since I've had the opportunity to build an enclosure and controls. It was fun designing the circuitry for the relays and related components and coming up with my own latching circuit and all that stuff.
I have the non-slider version of that saw. It's a decent little saw, I've used it for three or four years. It's certainly on the cheap end of miter saws, but if the slider is as good as the non-slider, it's well made and will serve you well. I've never given any thought as to the stickers, which are still in place...they're just there to guide the adjustment into the appropriate stop as far as I'm concerned.
