I've heard of using copper pipe (1/2 or 3/4) and a conduit bender. Shape the pipe to go as straight as possible between a keel bolt and the mast. Then flatten the ends and drill a hole to accept a large bolt. You can drill and tap the very top of one of the keel bolts to accept a short 5/16ths or

On my 1980 version, I assume the 'grounding' system is original. There is a cast metal box which the mast sits in and which in turn sits on the big oak block. That box has a battery cable bolted to it which is attached to a keel bolt. Hope it works. Gary #593 -Original Message- From: CnC-
