Sod it, I'd just run the buggers over.
If they can't see something like a JCB then they need a new guide dog. In fact aim for the guide dog first............... :ddb:

Andrew - at the amount of propylene glycol you would need you'd be in the poorhouse in no time. I only needed about 15 litres or so and bought about 20 undiluted. Can't recall the dilution rate but I've got enough for a long time - still painful on the pocketbook though.
John.

I decided to investigate further some switches on the front panel. I sort of half expected what I found, but it's a bit scary :bugeye:
In the picture below:
a/ the left hand switch is not connected, nor are there loose wires, nor is it labelled, so OK ignore it
b/ the middle switch does what it says on the box - turns the low power red laser target finder on, so it's OK
c/ but what about this one on the right? Turns out that it is in parallel with the safety interlock on the machine lid, the one that saves your eyes. Flick this switch AND THERE'S NO INTERLOCK :bang: :bang: :bang: :bang:
All rather nasty but easily sorted with a pair of snips :ddb:
To celebrate I made a pair of boxes - these are 100 x 75 x 50 mm out of 5 mm ply

Oh no this laser thingummybob is addictive, I can't stop finding new uses for it :lol:
