First off, thanks @ Patricia and KC!
Then onto the update for the day... I had planned on getting underway on the ceiling today, although somehow ended up spending most of the day working on other things. The most notable was getting a start on the structure that will house the fridge
, I was highly motivated to get to this as it had the potential to help close the gap in the door. The outer vertical wall was the key to this, and in normal circumstances it probably would have taken all of about three minutes to cut a piece the right size... but this area had a similarly Seuss-like collection of angles... and wait, don't forget to factor in 1/8" for the layer of FRP... and oh yeah, you wanted to have a cutting surface on the top, so you better figure out what you'll be using so the height is right...........
Fast forward a while and I finally had as baked a plan as I could and got started on actually working. Step one was as simple as lodging a 2x4 into place in order to get the shell to meet the contour of the door on the left side:
Once aligned I rough cut a piece of 3/4" plywood and traced the contour:
Foolishly enough I thought it would be as easy as screwing the cut piece into place and I'd be done, but the pressure required to push the shell out turned into another comedy of errors until I was finally able to get the piece installed and the gap not perfect, but dramatically improved:
I'm thinking that with some shims and tweaking the hinges I'll be able to get the gap closed in a little more, if there remains a gap then I'll probably need to increase the thickness of the shell where it meets the door.
