I ended up having to cut both the nut and the head of the bolt off before it would loosen up. Several whacks with a hammer and punch then what remained of the bolt shot out the starboard side of the keel box. Grabbing the end of the keel by the lifting shackle and it was clear that it was moving and lowered to the ground. Now the only task was to extract it from its home.
There was no way it would budge by hand so I tried attaching a block and tackle to give a little more leverage but to no avail. There was nothing for it she would have to be tipped onto her side and the keel extracted out of the bottom. A little brute force and ignorance along with careful placement of some carpet and she was balanced on her side and chocked in place.
Fortunately at this moment my Dad turned up and held the hull while I persuaded the keel from her home. It was clear that the corrosion was fairly advanced in places as the lower edge of the mild steel came away in large flakes. This was especially the case around the slot for the bolt as this part didn't want to release but with a bit more ignorance we managed to free it.
I suspect the rusted part may be too far gone to rescue so I'm going to investigate having a replacement made either in galvanised steel or aluminium alloy. I'll also reinforce the keel box very much like Bill Serjeant has on his C Type with some extra glass pads and washers. It is always good to avoid dissimilar metals from touching each other so a suitable plastic tube will go over the bolt.
Very corroded along the bottom and around the slot - otherwise fine!
and the remains of the bolt weren't much better
New ply base to build along with a compression pad inside - then the tabernacle
and the compression post needs making as well
It once has a depth gauge!
At least something fits - the drain plug screws all the way in
Next task - remove all the old wood from the cross brace and build a new one. Should be able to have that done during the week as tomorrow we're helping out at the marathon sorting out the runner's bags at the end. It's a long day, leaving the house at 6am and not returning until 7pm, but it's great to feel a part of an amazing event, though our thoughts will be for the dead and injured from the atrocities in Boston.
Enjoying the blog, you sound like you know what you are doing.i
ReplyDeleteThanks Michael that's kind but it wouldn't be possible without all the info that's on line, particularly Bill's Log.
ReplyDeleteMaking slow progress - ordering some marine ply today 12mm thick to build the cross member and I'm trying to work out if I can also build the rudder, stock and tiller from the same sheet. I'll still have a load left over so might build some more of the internal structure, though don't want it to be too heavy.
