BBSB restoration advice

[Richard Lathrop]

When replacing planking that has shrunk on a BBSB do you add an allowance for the shrinking when replacing planks? Do you try to use the same screwholes?

Since planking will be fresh but this project won't start for at least 6 months to a year while the planking dries out.

Got a photo of the planking gap (seams)?

I am wondering if the planking needs to be replaced. (I have certainly seen dried vessels where the planks have shrunk just too much....)

Can you close the gaps with Cedar splines? Perhaps set in a softer (compared with 3M 5200) caulk like BoatLife?

Just speculatin' ......

All the best,

Steve,

Unfortunately the ends of the planks rotted off and need to be replaced.

Wow, this looks like quite the project... with my 1928 Hallock white cedar boat I replaced the entire boards on top-deck and yes allowed for expansion however I did epoxy the hull anyways but knew the existing planking would expand pushing the new planks a bit as well. From what it looks like I would do a complete replacement of those planks there to ensure seaworthy safety. Are you planning on sealing the entire boat?

Got it - thanks!

IF you plan to use the same screw holes, I would squirt some epoxy in each with a syringe. If not using them - as too much deterioration around each - I would fill each hole with a fairly wet thickened epoxy - again with a syringe.

All the best,

Since the boat will live on a trailer my plan is to epoxy and fiberglass the boat. Purist may hate me but I think that is the best approach.

Allow drying to interior of the boat and fiberglass exterior.

Anyone have a recommendation for a good wood moisture meter?

Klein tools makes a very nice moisture meter I used this on my project along with inspecting boat transoms

I've always used a Wagner pinless for monitoring moisture levels in my wood blanks for turning. Can't remember the model off-hand, but will check when I grab pics of call stuff for the other thread.
