using brass tubes as drill bits....u can use brass tubes as drill bits in balsa....when the hole has to be the same size as the tube.....simply cut off a section of brass tube say 4" insert in ur drill and use a counter sink to sharpen the inside of the tube or exacto knife......

then hit the outer edge with sand paper to get the burrs ouff and then drill the balsa.....i put another piece of balsa under the hole so the edge of the hole doesn't get messy.....been using this method for years!!!

that's my tip for the day
