i've not done it with the air graver, yet. but years ago i took common xacto blades and shaped them to my desire and soldered them onto small metal rods. used these quite nicely with a gravermeister. the main blade portion must be immersed in water to prevent temper loss, but this can be done. theres a commercial carver called "automach". maybe their blades could be cut down to fit the lindsay-- just a thought. those blades are a greater quality than xacto, and pricier too.
