First big challenge - where am I going to build this ?
I couldn't negotiate access to the garage as Sarah won't leave her MX-5 out in the cold, especially for the length of time I expect this build to take. So the shed it is.
Trouble is it is only half the size I need. Some major mods needed. I'm going to turn it 90 deg, split it apart and rebuild to aound 5m x 2.5m that should do it
