The planking work has been progressing. We are working toward the turn of the bilge, replacing all the bad wood - either by scarphing in pieces, or by complete plank replacement. Complete planks have needed to be scarphed because of the stock - only 4 meters in length. But the scarphing tool and epoxy has made this task easier.
When the boat is finished to this point, we will lift her off the keel for the hog and stem work.
The wood is local Gotland's pine - very dense and resinous. A few too many knots to be ideal, but we work around them... And the wood doesn't seem to split at them, probably due to the resin and density.
Just alittle finishing of the scarph on this plank before fitting the last on the this side
Finally the port side completed... Time to look at the starboard side!
The first scarph cut for planking replacement, only LOADS more to do! Need to work out some fastenings...






Then out with the plank... How do I turn that flat plank beside into the banana that came out?
After a little work with saw, plane, angle grinder etc. it seems too fit well!

While I continue with the planking on the starboard side Oscar is stripping the old paint from the port side. This was only sitting there by habit, but we left it there to help keep the moisture content of the wood stable. Now it needs to go, before we spline the hull and paint the primer/barrier coat.



Only a week or two until we are painting her... Hopefully!

Planking!
Well the planking work has started.
As mentioned earlier we will be replacing the butt-joints in the planks with scarphed "hide-a-butts" glued with epoxy. This is to create a stiffer hull, and remove/replace the damaged end-grain in the planks. While there are a number of butt-joints per side we are minimising the number of "hide-a-butts" by incorporating them into plank repairs when we can - again with glued scarphs ( 8:1).
To ease this I built a little jig to help control the router as I cut into the hull.




This speeded up the process - 13 scarphs cut in the hull in a day! Most of what is needed on the port side. Then the tool was mounted on a bench for cutting the wood.



Neat repeatable 8:1 scarfs... Makes the job so much easier.

Here you can see two of the completed hide-a-butts and the first plank repair - being held in place while I drill for the ribs and frames.






Then it was time to put in one of the most difficult planks - constantly changing dimension, curve, and twist!



This is being held in place for a few days - I have to travel anyway. So that it can get "happy" with its new place in life, before I remove it for final finishing and fitting.
