Rebuilding the Square Meter: fitting the keel timber

We took the keel home to our shop to do a little work on it.
We laminated on an additional 1 x.  This will strengthen it and enlarge the rabbet.  This will help when it comes time to plank.

After the epoxy set up, it was back to the barn to fit it.  The framing tails were built a little long so we snapped a line and cut them.

Once the keel was set in position, it allowed us to fit in blocking for the keel bolts.  These blocks raise the bolt head up a bit in the bilge. They also are cut with a bevel to provide a flat level surface for the bolt nut.  Additionally they provide a little more beef to hang the lead keel on.

Here are photos with descriptions.

Here is the keel with the additional lamination of oak.
It is 5.5 inches wide at it widest point and about 3.75 inches thick.

This is the stern end.  The rabbet is now about 1.5 inches wide.  The funny looking ends will be whittled in place.

We used thickened epoxy with hardwood pegs for all the laminations.

The is the underside.  It will receive the lead keel.

The frames are beveled to fit the keel.  Blocks are added for support for the keel bolts.
The keel will be through bolted to the frames and the lead ballast will be through bolted
to these blocks.

When the keel bolts are installed, this will suck up nice and tight.

The bottom end is taking shape.

Rebuilding the Square Meter: Hull framing

We are fitting in new oak frames to replace the rotted out bottom of this 1929 Swedish Skarrie.
Using some drawing paper sheets, we are making templates for each location.  Since the bottom of the hull is open, we are able to press in sheets of paper and trace in the hull curvature for each frame.
These lines are transferred to the 8 quarter oak and cut on the big band saw.
Any additional fitting is done with a angle grinder with a 36 grit disk.

We have finished three frames and today we are forming 4 additional ones.  The tails are slightly long.
These will be marked where they intersect with the keel timber and cut accordingly.  Once everything is fitted, long stainless through bolts will be installed the hold it together.

Marking the intersection with the rudder for a cut.

This barn is awesome.  It is framed in massive walnut!  It is wood peg post and beam construction.
Really well built.
We will use its framing to hoist the hull off it's trailer in the coming weeks.

This main beam is a full 12 inch square of walnut.
You can see the adz marks.
Here is the mast hanging off it.

Rebuilding the Square Meter: paint stripping

After 4 passes and 6 gallons of paint stripper, we have started to see the strengths and weaknesses of the hull.  This is a race boat and is built accordingly (light).  This is good for us.  The ribs will be easy to duplicate.  They are thin laminations of steam bent oak.  The lower braces are heavy oak but are not very large.  These will be recut out of 8 quarter oak and either directly replace the originals or be sistered in alongside the originals.
Here are photos of the work to date:

The stripped cockpit.  We used stripper to both remove paint layers in the bilge as well as to remove the canvas deck adhesive.

The most recent paint layer was battleship grey.  The early layers were way nicer.  A pale blue layer covered the original orangy red.  Now that's a factory color!

It looks nasty now.  Just wait.

Here is the cut out keel timber,  The top has a rabbet for the planking, the bottom is flat to receive the lead keel casting.
We are duplicating this piece out of oak.  Here is a piece of 8 quarter (2 inch thick) oak.  Additional oak will be pegged and epoxied on to build up the shape.

Here is the big oak passing through the Silver Band Saw.   Finally a piece  of wood
that is the right scale for the saw.  The saw ate through the wood like nobody's business.

Here are two pieces of new oak that we saw cut to shape.  Tomorrow we will bond them together
and continue forming the part.
