Question Oh Joy refit 11/01/09, with questions about iron sickness..

Here are a few of the culprits, some of who's purpose I dont know:

In the stem post, there's this rusted bolt:



What it does, I have no clue. The head fell off as I was digging wood powder out of the slot to expose it. Apparently it had a white oak block in the slot once upon a time. Here's the head:



Here's the inside as near as I can tell. There's a hunk of wood in that steel beam. What it's purpose is, I don't know. It runs about 5' back from the stem.



Here are some bolts that are toast in the bow:



What are those blocks called? I know they're not butt blocks...


Also, here are some deck beam ends with rusted bolts. Some of these exhibit softness in the ends but most don't. Should I replace them all or just the soft ones? All of these bolts are slated for replacement if needed. Should they come out or just be treated and sealed?



Finally, I've cleaned up some of the rib beds aft in preparation for replacing the ribs.



Any suggestions on what ya see are appreciated...

What I see is a lot of work. Hat's off to you... and I worked in a wooden boat repair yard!

IMO if they were there originally, they they should be replaced. All of them; if one failed, then the rest are suspect. But to be honest, Dude you are probably the most knowledgeable wooden boat man on SailNet right now (there was someone who worked at a yard in MD, and was very knowledgeable but I can't recall who it was).

hard to tell in the pics Charlie.. was the bolt holding the inner stem to the outer? (stern post) You could save many of the timbers by using scarf joints, splines, or "sistering" Also don't forget "git rot" or other penertrating epoxy. I'd try and remove any and all iron from the boat. I know that bronze fastenings are very $$ and SS is not always the best for imbedded fastenings. Also there are methods of injecting epoxy. Were there any trunnels on this boat? I personally love that way of fastening in really old boats.
As always.... GOOD LUCK!

RXBOT is on a distinguished road

Ask them maybe or find a local shipwright to have a look and give advice.

Charlie,
If you don't replace them all, how difficult is it going to be to get in and replace them one by one once you have Oh Joy complete and back in the water ?
Wouldn't you figure that it's going to be a damn sight easier in the long run to simply do the whole lot now ?
Cheers mate
Andrew

I'm not sure what it's holding. All of the major structural members are attached elsewhere. No trunnels on her. She was C-flexed so she has a very solid and sound outer glass hull which I hate to compromise. I'd have to cut through the C-Flex to get to some of these bolts.

Impossible to do it later. Getting them all out is gonna take cutting into the C-Flex. Something I'm loathe to do unless absolutely necessary.
