The tourniquet works well. The trick is to lubricate the bead on both sides, I carry a 35mm film canister of tyre lube inside the fuse box, this allows correct slippage. There is room on the LHS on the 1100 fuse box, I keep it wrapped in a spare rag, which is then used to clean your hands when finished.
One then wraps the webbed belt around the tyre and uses a tyre lever to twist the webbed belt and pull in the tyre. You have to be careful that you don't overtighten the tyre and balloon it out, this makes it impossible to seal.
Using your second set of hands, you then start your compressor (I carry one) and with some little bounces up and down, the tyre seats a treat.
