Hi all
Having looked at the various options on the market for a pillar mount, there was nothing that suited my setup so it would easily fit under the motorbike cover (or clamshell cover). So with a visit to my local scrapyard and a bit of machining and bolting together, it is possible to build a very stable mount (600mm tall) out of scrap aluminium. It may appear a bit rustic (can always paint it), but it won't rust and I get to spend the £200+ saved on other things! If anyone is interested in the specs of the creation, say so and I'll post them up.
