The right thing to do in a project when you’re unsure how to proceed is to just procrastinate on it indefinitely, right? Then one day in the bath, inspiration will struggle like a lightning bolt, you’ll shout “Arcata!” and then do some recreational streaking, and the problem will be sorted.
Something like that, anyways.
We have had the bookcase door sitting on the floor in the family room for quite a few months now, and I’m sad to report distressingly few signs of providence and/or muses preparing to supply me with the perfect plan for getting it mounted.
Alas.
So I finally worked up the gumption to move forward with my least unsatisfactory plan. This involved attaching the top pin hinge to substantial blocking between the joists to help them resist the substantial horizontal forces that are going to be trying to twist the joists.
Today I cut the drywall to access the joists and mount my blocking and found this:

That’s a heating duct, right where my blocking needs to go.
I think I’ll go take a bath. Couldn’t hurt.
