Right,

What power?
Where do you buy them?
What to use for a power supply?
How do you focus it?
What will it cut / engrave given the power?

When are you coming to fit it and wire it up for me ?

Is that enough to work with ?:heehee:

Okay.......
Power - The one I used was 180mw 635nm (visable red)
Where to get/PSU & focusing all here http://cgi.ebay.co.uk/300mW-650nm-Re...3A1%7C294%3A50



This includes everything you need, really easy. Comes with lens & body which is 12mm od so you'll need to fashion a clamp for that. The lens supplied is plastic however so was the one I used.

To drive it, simply give it 6 - 20v when you want it to fire. I would reccomend either a transistor or solid state relay to turn it off / on as switching speeds could get to high for a mechanical relay.

Focusing is easily adjusted by rotating the lens at the end of the unit.

At 180mw - 300mw you will only be cutting foams up to a few mm's and vinyl / stickey back plastic.

for engraving, Pretty much anything organic eg; leather, Wood etc. Also most plastics but results will vary depending on the colour of the material, A red laser will hardly leave a witness mark on red plastic and would struggle to set fire to bright white paper. However if was a slightly darker colour paper would ignite almost instantly.
