These are my first thoughts on the control circuit for the laser tube.
May be changed a bit after I have thought it through but looks good for now.

Pretty basic stuff but this is the proposed cooling circuit.

Another piece in the grand jigsaw puzzle has arrived from the USA. This is the Gems Sensors flowswitch - it has 1/4 NPT threads and I have made hose connections from stainless and phonelic which can be attached with pipe fittings.

Started getting the parts fitted to the machine. Radiator, circulating pump and flowswitch are in place. Still waiting for the header tank and fan guards but this will not hold up the wiring etc.

Now that the beam steering fixture, mirror positions and adjustments have all been carried out using the HeNe laser it is now time to fit the CO2 tube onto it's mountings and connect the wiring and pipework. I have also fitted a small, digital milliamp meter (to the front of the laser enclosure) which will display laser current during use.

Just engraved some of the obligatory labels that have to be fitted to the laser housing.

Looking very good  Smiley

It's a hefty cooling system you have installed.

Thanks Guys.

I keep wondering if the cooling system will be man enough for the job.  Grin

Well, maybe one more fan to be sure it can handle the load Wink
