Hey Scott
There really aren't any great videos, but some on youtube were helpful. It seems like most people making
signs by hand with a router are just making the same cheesy cedar
signs with black lettering you buy at all the flea markets.
Honestly, it's not that hard. I just put down vinyl for the pattern, then shot it quick with some spray paint, removed the vinyl, and started routing.
I did modify my router a bit with a larger clear acrylic base to bridge the larger areas. Other than that, just sanding to clean up the edges is the main trick.
Give it a go Scott. It's pretty fulfilling to make something by hand.
I also just ordered some chisels to start practicing hand carving. We'll see how it goes.
