Mast rotating bearing

Published date: July 27, 2008
  • Boat Type: Boat Type

After installing new standing rigging one of the down sides was the mast refused to rotate in light winds this is what I have come up with. A standard wheel bearing pressed on to a manufactured spigot carrier bolted to the lower mast bracket, the outer race is tac welded to the mast upper bracket sitting on a conical washer (allowing clearance for the tapered bearing when mated) then covered with waterproof sealant (it looks a bit rough). The original bolt that joined the 2 halves was drilled out and a longer bolt inserted and tac welded in position. The entire race faces are coated with a liberal amount of grease and should last for at least 100,000 miles or 3 years if I can keep the rust out.
