Rob,
The credit isn't mine but V Carves.
The Llanfair badge was just copy pasted from text off the web [ you don't expect me to be able to spell this ?
], brought into V Carve as text in New Times Roman, a box drawn round it and told to do internal radii and that was it.
The code went into Mach and it was cut using a home made 20 degree vee cutter like a D bit.
The Tich badge is CNC cut but it's been spay painted with wrinkle paint then linished when dry to give the cast effect.
Shoot me a DXF of your badge and I'll sent the code back so you can have a play.
John S.
