Couldn't you laser the smaller ones with a reduced vector? 


I could have, but there is a limit to how small I can make the vector and have it legible when burned into wood.

Ignorant of other's software (and techo experience), but do you have a SVG copy?

I have SVG'd your avatar and tried a few sizes,

That tiny one is 9.56mm x 13.4mm... loogs clearer in real life (that's a screen dump of a screen dump),

If your first cut is too short... Take the second cut from the longer end... LBD
