Need to drill some holes in the top of my mast to attach a Hobie mast float. Haven't worked with metal before...do I need a special drill bit to do this...or are my standard set of "Craftsman" bits up to the task?
Any time you drill into the mast, be sure to coat the screws with silicon before you insert them. It not only makes the mast more watertight, it also helps prevent corrosion due to the two dissemilar metals (alum. and steel).
