Thanks NRML for the kind words.
The laser needs water cooling, and now I've sorted out the power out sockets (incidentally labelled power in on the machine
) the time has come to sort out my water system.
They supply an immersible pond pump and suggest using a bucket, which is what I've been doing, but that has a few disadvantages:
A) I'd like to use anti-freeze as the machine is next to the roller shutter, but not in an open bucket when my dogs come to visit me playing in the workshop - anti-freeze is poisonous.
B) I just know that I'm going to kick it over at some time, because I do that sort of thing (unintentionally
C) An open bucket attracts 'stuff' - this one fills up with dead spiders, some of which float, and others sink
Now there are commercial coolers available with enclosed tanks, flow alarms and temperature alarms. All very good but they are really rather expensive for what is essentially just a coil of pipe with a fan blowing over it, so I've resisted up until now.
