Brilliant idea Sam. I just wish I was clever enough to do it.  :'(
I think the best I could achieve would be a blob which may look something like a bell Brett and as nobody has fingers small enough to ring it who knows if it works ?.

Certainly won't be able to cut stainless Gary but it should be OK for thin acrylic etc.

I have now constructed the header/expansion tank (which has been fitted to the rear of the laser tube enclosure) and an inline filter (fitted at the circulating pump inlet). The cooling system has been filled with antifreeze and is being tested for leaks (none so far, but don't hold your breath  :)).
I was pleasantly surprised to find that the system cleared itself of the trapped air after the circulating pump had been running for approx. 15 minutes.

Now to make a start on the control electronics.

Looks real good so far Tweakie.

Thanks Brett, so far so good.

Well made a start on the control electronics and cut the circuit board this morning. I am hooked on this 'isolation routing' method for making simple, one off, circuit boards - it is so simple and with no mess. Now to fit the components and bench test it.

A couple more parts made for the grand jigsaw puzzle.

That machine just keeps looking better all the time, Tweakie. I wouldn't want to use it for woodworking in fear of getting it dirty. You might just hafta build a dedicated router now.

It seems like you are able to spend a LOT of time on this project making it look equal parts awesome across the board.  One of these days, that secret must be passed on how you can do that;)

I think it's an optical illusion Barry - you don't get to see the stuff that goes in the bin.  ;D

 ;D Ain't that the darn truth. My scrap yard is much more populated than my 'show and tell' yard by far. Nice to know I'm not alone.
