| Post subject: | Broken Pintle Machine Screw |
Oh now I'm in trouble. I got out the ones in the broken off lower pintle. I got out the one in the chainplate that was going to be a problem and now that I started to put the boat back together I broke the head off one of the upper pintle machine screws. What's in there? A threaded stainless insert that goes into ... anybody know? Matt? Heat is not an option. Welding is not an option. I don't think easy-outs work. I'll squirt in liquid wrench but the boat was in salt water so .... Try drilling down the centre and then using a larger drill? Down the centre ... Oh my, now I'm in trouble. I didn't have a Hobie day. |

Depending on the boat age... Aluminum Stainless or Brass You may be drilling through and using through-bolts and backing nuts/washers. |

For those of you keeping score, or who almost care, I took it to a machine shop and he drilled it and used an easy out to get ... half of it out. Broke off. Then drilled the thing out and ran a tap in. It's a little sloppy but I'm trusting that Loctite or maybe epoxy will fill in the gaps. Then we'll all cross our fingers and go sailing. $150. One and a half hours at $100 an hour. Machine shop rates. Oh well. It would help if you bought the spinnaker kit in the classifieds and then I could afford it. Have a Hobie day! |

From what you're describing, there isn't much material left in the threads. I would either drill and tap for the next size larger screw (1/4"-20) or install an inspection port and thru-bolt the gudgeon with a nut and washer. Counting on Loctite or epoxy to hold your rudder onto your boat is a bad idea. sm |
