Does anyone have one of these? I've had mine installed at the Steampunk shop 'Knowledge' in Brighton since July and just discovered someone has walked off with the screw that locks the shaft from moving up and down.

What I need now is someone with the same unit to do some basic measurements on the screw/component so I can another one made as a replacement. http://www.youtube.com/watch? v=jGRqEq6piWw

Is it an imperial measurement as those screws are hard to get in the UK.  

Anyone in the UK with one out of curiosity as well.

Cheers

Mark
