David D,
It doesn't matter who gets the info across, it saved me a job 'cos as you know, I would have made a meal of it, with piccies as well.
As long as everyone understands how to do it, then no probs.
IMHO, having used precision levels for all my working life, I just don't know what I would do without one. I use mine for all sorts of things, not just levelling up machines.
Actually my largest is broken at the moment, for some reason it decided to empty itself, now I have got just one big bubble, no liquid. I have priced them up to replace, and they are reasonably priced. But because they are only available from the manufacturer, and they have a min order of 50 squid, with vat and postage it will cost me about 65 squid to repair. I will just wait until I can get another of fleabay, and keep this one for spares.
