Didn't get started until Saturday afternoon and as usual I had a bit of a clear up first then carried on with the drywall.
I just had a couple of small pieces remaining on the left-hand wall which were completed pretty easily. I then lined the opposing wall (right-hand) which went up really well. In fact I've noticed that the right-hand side wall is a lot squarer than the left. Just shows how you improve as you go - the left wall was the first to go up. No big deal as we're not talking about huge amounts, certainly not in terms of household wall construction.
All fairly straight forward stuff and completed in about an hour or so. The front wall wasn't quite so straightforward as I had to make provision for the electric lighting cable and the multi-core. The 1mm T&E lighting cable required a small slot cut at the top of the wall sheet and I drilled a hole and threaded the multi-core through before screwing it to the wall - tidy job (I'll need to do the same for the other layers).
Although the layer is not complete - I still have the doorway area to line, I thought I would caulk and fill the walls I had completed so far. This takes a little time as I filled all the gaps in the corners, joints and above the screw heads. >>photos<<
That was pretty much it apart from a quick tidy up ready for next weekend when I'll line the doorway and and door frame area. This will be a bit fiddly with lots of small pieces. Though before I start that my father-in-law is coming up Fri/Sat with his circuit test gear so that we can check out the ring/lighting electrics before I finally seal the room with drywall - just in case there are any problems with the electrics I need to deal with.
Acoustics: I'm going to start mentioning the acoustics in the room now as it will start to become relevant. With maybe a short comment when something changes. At earlier stages, although interesting, the acoustics were slightly irrelevant as it had little or no real impact on the final room. As you can imagine the room went from being very live with the brick exposed (it actually sounded quite nice) to completely dead with the stud-work filled with mineral wool. Now with effectively three walls and the ceiling dry-lined I'm getting the feel for the space and its sound. Although I'm still not going to be carrying out any detailed tests yet I'm able to comment on the general audible changes. I think I commented on the changes when I attached the first two ceiling layers. With the two side walls lined the echo chamber effect was multiplied and with the front wall lined...well you get the picture. It sounds awful!!! It is now obvious how small rooms are tricky to control but I'm confident that once the room is treated I'll get it under control - though I'll probably not have space to move ;-).
