Allen bolts for fixing down the pier adapters arrived today, so this evening I got on with fitting those to the tops of the piers and putting the mounts back in place. There’s probably no reason why I couldn’t go for an initial alignment on the next clear night now, assuming I can find a 12V supply for them.
The floor tiles didn’t arrive today however, so once again I hoovered the floor and then finished up my first tin of varnish giving the floor that I sealed last night a second coat. Hopefully the tiles will arrive tomorrow and I can start laying them.
