AKA my new workshop:
It's an 8' x 8' (2.4m x 2.4m) shed with a stable door (To allow me to get some air in there and keep the cats out. Paws + swarf = unhappy kitties). The interior is going to get insulated with foil backed solid board foam, and then a skin of OSB will go over that. Then I'll be building some benches for the machine tools, and getting a sparkie to come out and hook up some power.
Then move these in - an Axminster ZX25M Milling Machine (Second Hand):
And an Axminster SC4 lathe (also second hand):
Then I'm all set to make expensive brillo pads and odd shaped door-stops.
