Thanks John.

I had a few samples cut out and it came up well on the mechanical engraver. I asked a local trade engraver to do the aluminium and they said the couldn't. Also, Identify in Bristol said no laser. Your making me doubt myself now as I was also talking about cutting frp plastic as well. Hmmmm?

I am looking to get a fair bit of daily use out of the machine so happy to look at any method that you guys think might work.
