George:

Possibly a step bit would work. Alternatively you can use a hole saw with a piece of dowel over the bit that is the approximate diameter of the existing hole. You don't need to epoxy it in place as it is used only as a guide.

Subject: Re: [Rhodes22-list] Rudder Bolt Hole Enlarged

Graham,

I do plan to use Roger’s technique.  I’ve got the epoxy and I ordered the
silica and graphite. I realized in order to drill the hole out larger, I’ll
probably have to epoxy a wood plug into the existing hole and cut it off
flush with the rudder. This is the only way I can think of to give the drill
bit a center point to drill into. I wonder if there’s an easier way?

George
