OK, I set to work getting the bulkhead light installed. This involved simply taking another feed from the lighting junction box and running this through the stud-work. I added the isolator switch to the left of the fan controllers and connected everything up. The light itself is not secured in place yet as I intend to tinker with the position. I'll probably have it positioned slightly angled downward to light the required area.
I had also decided to run an additional CAT5 cable into the garage as an additional redundancy that I may put into use at some stage. This cable, along with the additional telephone cable feed into the house, results in two more CAT5 in total. This works quite neatly as there is enough space next to the original sockets for a second 2-way wall box. I fed both cables through neatly and clipped them down through the stud-work and terminated them into the new box.
Multicore feed:
So far the multicore was just looped through the stud-work centrally in the front wall. To neaten things up a bit I took a stud-work off-cut and cut a 19mm hole in one corner. This was then screwed into the stud-work corner with the multi-core through the hole.
Another small job to complete: the thru anchors used to secure the stud-work frame to the floor came with plain washers and a plain M10 nuts. As I won't be able to access these again once the drywall is in place I needed to ensure that the nuts won't loosen over time. I was considering using some stud-lock but I have some M10 nyloc type nuts so I put these on instead. This took a little while as the are a good 20 or so thru anchors in total. Another small job complete. This was also holding up completion of filling the stud-work with mineral wool.
I could now carry on filling the walls with mineral wool. This was just a matter of getting back to the routine and I now have 3 walls filled
One thing I have realised is that I could have routed the two 2.5mm cables for the studio ring in a much better way. Instead of running these between the brick wall and the frame I would have been better off routing it along the same route as the other circuits along a joist then down
