Carrianne Rot repair 09


Last season I posted a series of images and text on repairing a rot I had in the transom. One Fourmite mentioned that there was the possibility of deeper rot. He was right.
It was much more extensive and only showed up on the outside by a slight crack in the paint next to last seasons repair. After examining the region I determined to just cut out only the area of rot and replace just that portion rather than tear off all the transom plywood and oak. I could live with the resulting splice of only a few inches revealed in the varnished oak of the transom

Image 1 shows the ply wood cut off revealing the rotten oak. I have rough cut off the transom plywood. The masking tape provided an easily visible line to follow.

I used a 10 pt hand saw to cut out the rotten oak. This view shows the cut being made following my guide lines. The angled cut will provide more glueing surface later.

The cut as shown from the opposite side. How nice the oak appears on this side.

In this image the replacement oak is being checked for fit.

The discolored wood in the boat is , just some glue & age related but sound wood.

This image shows a guide clamped to the transom for the router to follow in making the ship lap rabbet. The clamps were removed as the rabbet was cut and reclamped behind the router.

This image shows the ship lap rabbet in the existing plywood of the transom,

Now I'm wating for some decent temperatures to glue in the oak. Inthe meantime I can rough fit the transom replacement plywood.

So the water came in through a faulty glue line between the plywood and the oak?

Nice work and cute boat:)

Mizzenman,

I could not determine the source of the rot, water intrusion, maybe between the oak framing and the 1/2' plywood.

Today I was able to glue in the oak framing and fit the replacement plywood.:) I had to enhance the winter cover to retain some heat which was applied by a small electric heater. Hoping tomorrow to glue & screw the plywood but it promises to be a cool day as well.

In this image we see the clamping arrangement. The plywood has one layer of 6 oz FG cloth applied with epoxy. It has been fitted and screwed in place, a dry run with no epoxy glue.

The large clamp in the middle is to apply pressure to the rabbet that joins the old existing transom plywood to the new.

In this image we can see the inside clamp arrangement. Notice the duct tape. It held the padding in place temporally enabling me to position the clamp easily. No glue so far. I made a sketch of just where all the clamps were to be placed when gluing time came.

Here is the way the outside looks after gluing the plywood. The screw holes have been filled and fairing done withEvercoat Formula 27 All purpose filler.

This image shows the inside. Not quite ready for paint and varnish.

The gudgeon needs to be mounted and the rudder hung with tiller to determine if there is still clearance when in use.

Next, some painted shots of the finished job.
