More insulation. Note ‘slide’ I built to get bags of concrete into the basement leaning against the far wall

For those who haven’t heard my constant complaining, I am finishing the basement in our 1920’s vintage house. The house is pretty small and to boot, also very narrow (about 12 and a half feet wide on the inside), so getting the most out of the space means using every inch effectively.
I wanted to start documenting what I have done, even though I have completed a lot of work to date (and many trips to the nearest Home Depot).
So for those of you who have been asking here are the latest images.

Basement rigid insulation  fixed to wall.

I finished putting in the rigid insulation and securing it using strapping and many tapcon screws, so that I can have a surface to attach the drywall. I am using Type “X” drywall for the walls and want to get all the surfaces trued before I start putting it up. As you can see the bottom of the wall is not quite in line with the rest of the wall, so I have to shim a bit to get everything straight.
Also, have to wait for the Electricians to finish rewiring the basement next week before I can put up the ceiling drywall and tape.

Bulkhead for gas line

Sunday, as I was looking at the bathroom, I decided to take a peak under the drywall on the exterior wall of the bathroom. I was trying not to disturb too much in that room as I wanted to focus on the main space, and besides, it was already pretty much finished, except for some awful cedar siding which I ripped out. I was just going to patch these areas and put up a new ceiling and call it a day, but as these things go, there is always something else hiding behind the wall.
When I looked behind the old drywall, lo and behold, there was no insulation behind the wall. Hello? Exterior Wall? Insulation? I thought that generally insulation was supposed to go against the cold wall of the house, but I guess the person who renovated the house in the 70s wasn’t so fussy. So I figured, take out the drywall and put up the rigid insulation to take care of the problem. As I took down the drywall, I noticed an area of about 9 x 3 inches which had insulation stuck in it. I had to remove this and it was really dirty. Why was it dirty? Well as it turns out, it was covering a hole in the wall which went straight through to the outside! No wonder the bathroom was so cold in the winter!

Bathroom bulkhead built around exhaust fan using existing hole in wall.

But hey, never let an opportunity go to waste. I was going to replace the vent fan anyway (the old one just vented into the joist space, duh), so I went to the Depot on Monday to buy a fan and duct so that I could use the hole to vent to the outside. So what if I had to wriggle myself under the front porch of the house through dirt and stuff to install the duct from the outside and seal it. All in a day’s work.
Hooked up the fan and the duct and built the bulkhead for the drywall and thought, this was just supposed to take a couple of hours; what happened to the rest of the day?
