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

[CharlieCobra]

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...

Charlie, The 1st picture is so much of a close up that I can't tell what I am looking at. The wood within the two formed channels that make up the beam is a compression member to prevent the channels from collapsing inward. There should also be some bolts going from one channel to the other to prevent the channels from collapsing outward, and to make the wood and metal pieces into one beam.

As far as the punky deck beams, if only some are soft and only at the ends I think I would treat them with Git Rot, Boraban, Or Penetration Epoxy. If they don't come out to your satisfaction you can always replace them. If your deck is fastened to them however removing them may not be non-destructive.

The bolts all look like toast.

Good luck

Charlie, more questions. I also couldn't see enough of the blocks to tell you anything about them.

Is the plank wood under your old removed frames soft? I think If you had not intended to replace the planking that it would have been better off to treat the old frames and put in sisters so you could fasten through the better part of the planks. Since you didn't do that you, should probably put in wide frames so you don't have to fasten through the existing planks where the old holes have been drilled.

Have fun

Joe,

I'll take another picture tomorrow but your explanation fits nicely. I believe it was white oak stuffed in there as the stem is mahogany. There are other bolts but they're fine. No water got to them.

I'm going to evaluate them one by one as I replace those bolts. They bolt at each end so are simple to replace. The camber is easy as is the joinery. The deck does attach to them.

A few are, just under where the ribs were. It's a moot point as Oh Joy is a C-Flex boat. There one layer of C-Flex and two of glass over the planking from the keel to the halfway point of the sheer plank about 4" down from the bulwarks. The planks are NEVER moving again nor are they keeping out water. I'll saturate the areas with CPES and attach the new ribs from the inside out. They have no real structural significance anymore but she would look funny with blank spaces there.

Here ya go Joe. That bolt in the stem appears to go nowhere and that steel beam is actually wood and slotted for the centerline bulkhead. Here's some new pics.
