Alright, I need to make this as short and sweet as possible, since it's late and I'm headed to bed.
Here's the work on the built-in. The grooves look like they're rectangular because of the plywood effect, but they are definitely V grooves. Unfortunately the first photos are blurry, but they're all I have.
The V grooves were just marked out at 3" intervals (centred on the board), and I set up the router with just an MDF straight-edge (actually a baseboard piece).
Here's the issue I'm dealing with regarding the old drywall at the ceiling in most fo the upstairs. Basically, back then, they only nailed it in place around the edges of the sheets, and a bit down the centre, so over time, under the weight, it has all sagged in rounded sections. My solution is to add new drywall over the old (for several different reasons which I won't go into). To do this properly, I still need to snug-up the old drywall back flush, so I used washers and drywall screws. You can see just how terrible the ceiling looks here.
This is in the Guest Bedroom (aka Laundry Room).
The ceiling in the bathroom was just as bad. I covered over it the same way. The ceiling in the hallway, staircase, and half of the MB have already been previously capped over with new. One half of the MB is sagging a bit, but I left it as-is.
The L Room, however, is a whole other nightmare. Some dipshit smeared a thick layer of plaster over all the awful old ceiling using a BROOM. Doesn't that look just awesome?
So fortunately, most of it chips off pretty easy, so I started on that a few months ago, and did a whole lot more this past week.
FUN. The worst, however, is that I think they replaced one full 4x8 sheet, and it was unpainted when they added the plaster, so it will be an insane nightmare to try and chip that crap off.
Here's some random shots of the recent drywall and closet work between the Guest Bed and L Room.
This is the outline of the Guest Bedroom closet. Obviously it won't be functional until the chimney is gone, but I'm really hoping I can get that removed next year?
From the Guest Room side:
PS: I've been reusing some spare pieces of the waterproof (blue) drywall leftover from the bathroom reno, along with new sheets of regular drywall, so that's why there are random blue sheets.
This shows the inside of the L Room closet, over the built-in. There's a decent amount of space up there, and there will be a wooden shelf mounted over the top (since drywall would eventually get damaged too easily). It should look quite similar to what I did for the duct work in the MB closet (see here: http://i1018.photobucket.com/albums/af308/clockmaker15/HOUSE/PB018430.jpg) only MUCH higher.
