Ah proper Overhead projectors
Spent quite a few evenings aligning tubes, hanging from rafters with the top casing off, twidling screws to align the seperate RG&B tubes with a little insulated tool thing trying to avoid falling in to all the humming HV bits. of course next day I'd have to take it all down and move to the next venue :-(
That was when I still had a spine :-).
