did you know that CO2 lasers are, apparently, better at burning corneas than they are at retinas

I don't believe you. Now, I know your going to stick to your beliefs, and I'm set in stone on mine. So I guess were just going to have to settle it once and for all......We need an idiot brave volunteer.  Evil  Evil

Already tested the theory Sam and Super Kitty can prove it.

The new PSU enclosure is now, more or less, complete - just the protective earth terminal and ground strap for the lid and a small EM screen and thats it.

Warning label (engraved into traffolite) for the front of the PSU. First time I have tried this, it was 'raster' engraved rather than 'vector' and it took forever.

The High Voltage PSU is now complete and it's time to start working out the best beam path from the tube to the Z axis.
I have made a frame of the same OD as the CO2 tube to hold a little HeNe which sits in the CO2 tube mounts and is ideal for this job. The mirrors I am using are OK for the 633nm and getting the beam path sorted but will need to be replaced with a type that works at 10600nm.

A bit more progress on establishing the beam path. It has to get from the laser tube to be running parallel and plane with the X axis where it is again deflected (by a mirror on the X axis) to be parallel and plane with the Z axis. The focus lens will be mounted directly on the Z axis whereby the focal point can be adjusted for different thicknesses of work.
This is the wooden mock-up including adjustable mirror mounts made from MDF (yuk !). The little HeNe beam is quite square to the table in both planes which I think has resulted from a lot of luck.

Somehow I think with you working on this project, it's a bit more than luck...  Wink

Just fantastic, my friend  Smiley
