I decided it was time for some serious rust and metal removal, so I bought a compressor and some air tools.
I did my research, and took advice, and it was very clear that I had to get one with sufficient power (measured in air throughput, normally in cfm – cubic feet per minute). I investigated loads of machines and suppliers (finding one who will send one up here for a reasonable price is quite tricky), and then I spotted a bargain on eBay from a supplier in Germany (made in China, naturally), and somehow I managed to forget everything I’d learned, and bought it. Delivery from Deutschland, Deutschland, so gut nannten sie es zweimal, was actually less than most UK suppliers wanted.
And of course now I regret it, as it’s underpowered for what I want to do, as in cutting, grinding, hacking and slaying. I have to keep stopping to let it catch up. It supposedly does 7 cfm, but in reality it looks like it does about four. I knew that manufacturers normally quote the theoretical throughput – the piston displacement, but the actual output you get at the business end is much less than this. But somehow in my quest for a bargain I managed to forget this. So let this be a warning to you! I’ll probably replace it with something a bit beefier when I can afford it.
Anyway, back to the car, and its floor. I hacked away and removed lots of rusty bits, thinking I could patch it. Let’s not forget, we’re not going for concours, we’re aiming for a car with no holes and rust that we can drive around and have a bit of fun. But it soon became 
clear that there were more patches than floor. Many of them well done patches, it has to be said, as well as the tack-weld-a-bit-of-metal-over-the-rust variety, of which this car has many. Or it did have, before I was let loose on it. So now it looks like this:
It probably looks a lot better in the picture than it is in reality. So it’s got to go. Fortunately, being an MGB, replacement floor pans are easy to obtain, and quite reasonably priced. And what’s more Moss are having a 20% off sale this weekend. And their delivery charges to Orkney aren’t too bad at all. So I will get to use this:
Flash Gordon or what!
