I used a cheap pantograph fitted with a Hitachi TR-8 800 watt router, to make many signs particularly in hardwood - Ash. Never had a problem.
I used a single flute solid carbide 1/8" diameter bit from memory and it cuts like a knife though butter, the bigger the bit the harder it will be, some people use a V bit.
