Hi, First time routing out some aluminum sign shapes (12 x 18 custom shapes). I'm using a 3/16" spiral cut bit at 21,000 rpm, .125" per second feed rate, cutting .080 aluminum. I used a piece of scrap 1/2" OSB board for my sacraficial material. The osb wants to burn. I had to use a water mist to keep from catching on fire. Is there a better material to use under the aluminum? Thanks!!
