HEPA=Hell, Every Progressive Approves!!
I just installed the jog in the cold air return and am quite pleased that i did not have to cut the 60" straight in between the 45 degrees in order to hit the chalk line in the image. You say luck I say karma (or luck). I had to trim a 12" piece off a 30" piece just before the jog and recreate the features for the cleats, ugh!!! I have gained a whole new appreciation for tin knockers.
Now just 8' straight to the stairs and joists that will be panned for the return on the main floor.
Then finish the remaining 4 registers to the living area just in time for summer.
