Got meself a new toy
John Stevenson:
Still doing a bit of playing. machine is dead easy to use but getting parameters right for different materials is a different learning curve.
Been doing an Imperial screw cutting chart for my metric C3 lathe and can get consistent results like this now.
This in metallic laminate, scaled the merlin badge down and did it on the same material, came out reasonable but the merlin artwork is quite fussy and doesn't like scaling too much.
It's only 2" x 2 1/2" but was just an offcut of the laminate, not cut the sheet of gold coloured laminate up yet.

Yer, definite room for improvement, I'll keep trying. :(

This thread left me feeling left out so I'm now also 'lasered up'...
So John, I have a question about the 'engraving' you did on metal.
I did some reading and the stuff I found suggested that Thermark is actually a suspension of glass...
Now it turns out my other half is a glass artist (which means a bloody huge kiln occupies the space the Bridgeport I don't have should have been in) so I 'borrowed' some of her fine glass powder and mixed it with alcohol, painted it on and 'engraved' it.
What I found was that it did indeed work, although my application using a brush was a bit 'uneven' but the etching isn't really etching, instead it's a fine glass 'bead' that's attached to the metal and as such it's raised.
Am I on the right track here? Looks like the real issue would be to get the suspension into an aerosol form so that it can be applied as a thin even layer.
You're right about materials, experimenting to find the right power and speed for the job in hand is something that would benefit greatly from experience. Good fun though, although looking at the amount of smoke that sometimes pours from the exhaust I'm not so certain of it's ecological credentials...
