Andy just do a search of Eugene Kings posts as he sums it up pretty well and also sells plans for some of his products to get you kick started. Eugene also teaches one to use up every bit of time whilst the bot is cutting. Truly you can make just about anything on the bot and your whole manufacturing concepts and methods will change. As you already do furniture why not think of value adding by incorporating lots of v carving? Yesterday I took a crappy chest of draws, took the top off and v carved the top of Mike Tylers Paradise box by scaling it up. Looks absolutely stunning and took 26 minutes!
