i am a sign maker vinyl ,pinstripe, hand...trying to router a sign and never used a router...I want to do raised letters with a smooth background, have no idea what bits to use...keep in mind i am very new and be very specific what bits to use, i sure more than one will be needed because of background and fine work...i have a fixed base router...any advice will be appreciated...and i guess procedure would be nice too...all i know now is to glue a pattern onto the wood, and now i need help...thanks
