Glad you like the shed, I've no idea how old it is, a couple of hundred years easily. There's no foundations and we're in earthquake country, some one knew how to build 'em!
I'm sure I could make movies, but I's a skill I've no real desire to learn. I have a fairly basic phone, no face book site and the lowest internet profile of all of my mates.
The castors were all I had to hand, when I find a home for it I'll go down the concrete base route.
The alternator I found in the 'layapart' of a shipyard down in Tarragona, whilst working on a rich blokes motor yacht. for 100 euros they even loaded it into the back of the Landrover.
Cheers
