More Glass

Time to layer on the cloth again.
I had to buy some more cloth. But should have enough now to finish the boat.

I am getting better at this than when I started for sure. Again finding it is so important to lay out and press the cloth into it's location before applying resin. This time around I am actually enjoying doing the fibreglass because I have learned what not to do.

Another trick this time around can be seen below. I tilted the hull over when doing this side to make applying the resin easier.

Long panel

I have made the long piece which forms the bottom of the inner wing. It is about 6 metres long using scarph joins and kind of looks like a big wooden banana.
Here you can see it upside down to get an idea of the curve involved.

This is actually an earlier photo which shows that I glued the scarph joins with it in place to get the curve just right and used some plastic film to stop it sticking to the hull so I could later remove it to fair the edge where it meets the hull.

And here is the final result. The board has been glued in place. Then the big fillet join added.
Also all the screw holes have been filled and the hull routed and faired, ready for fibreglass.

As you can see the port hull caught a hail of wood chips from the fairing of the hull. Looking forward to getting this hull up the right way to see them side by side.

Inner panels

I have the inner panels on now.

You can see in these photos that the panels are oversize, it is a quick job to sort this out later. You can also see a bit of the glue squished out. I like to see this as it means I used enough!

One thing which you can see in the next photo is that my garage is getting very messy. Time for a clean up maybe.

The build is going slow and steady. Each panel was done in a separate session, each one probably took about 3 hours to measure, cut and glue. My time is still very limited but I feel this build method works well for me because I can divide the building jobs up into very short time periods. Sometimes I only get a 1/2 hour work session but I can still do something useful in that time like cut out a panel or make some measurements.

First starboard panels on

Slowly the second hull is taking shape.

Here are the latest pics showing one side (the easy side) done. It is a good thing I pre coated these plywood panels with epoxy back in summer, the weather has been very cold and damp lately.

The only thing I'm doing a bit different this time around is doing a more tidy job with the glue and also I am epoxy coating the stringers at this point also as it is easier to get to some of them and there is no dust collecting on them at this point which helps.

Making a Hole

I would like to have a depth sounder on my boat, but where I could put one? Transom mount would be easiest but I expect the transoms would be out of the water some of the time especially at rest, a through hull would get squashed and be draggy, so I decided that in in-hull transducer would be best. However ultrasonic signals can't punch through wood, so what to do?... Drill a big hole!

It felt a bit wrong drilling a massive hole in the bottom of the boat but this small piece of the hull will be solid GRP so that the transducer signals can get through. This is another advantage of the flat bottom of the hull which makes this process quite easy.

Here is the first stage where I have wet out glass cloth on a piece of plastic film and pressed it against the inside.

Once cured I filled the hole with thickened epoxy.

Here is the finished result looking from inside the hull.

As you can see, light gets through. Hopefully the signals should get through also.

First Starboard Plank

The bottom is on.

In this photo I have put the plank on to check for size and mark out where the glue will be going. You can also see here the cuts made in the stringer to get the tighter curve of the rocker at the stern.

As with all the plywood panel gluing I sand and recoat with epoxy where the glued surfaces are including the stringers. All plywood I use I have pre coated with epoxy on the interior side twice, with a light sanding between coats. I prepared quite a few sheets back in Summer when it was an easy job, which should get me through the winter.

Here the bottom is glued in place. Notice I have also installed the inspection ports already.

At this point I am ready to start fairing the stringers prior to putting the hull panels on.

Building efficiency

Now that I have started on the second hull I have come to realise that building the two hulls separately has not been such a bad thing after all. Not that I have made any big mistakes on the first hull, but I have developed more skill building the first one so I have learned how to do things more efficiently this time around and seeing what the finished hull looks like, I can see what parts of the construction are more important.

Anyway here is some more progress to report. Hopefully I can give some other insights this time around.

First stringer on here. This was chosen as it is the straightest stringer in the hull so has the least tendency to push the frames around (which is bad). The framing I set up for the bulkheads does not hold them in place very securely so need to balance these pushing forces as I go and keep using the laser level mounted above the hull, shining down the centre line. To keep it perfectly straight until all the stringers are on.

In the pic below you can see where a stringer joins to another one with a scarph type joint. It is this bow area which is very hard to visualise until you see it like this.

Here is a pic of the bow locker floor being glued in place. I did this the same way on hull 1 and it worked out well. Once the sides of the hull are on it is very time consuming to cut a panel to size, such as is the case with bunk panels. This way it is quick, as it is cut over size and faired when the stringers are faired.

Temperatures have got low again here so it is good to have the fibreglassing and painting done for now. This wood working and glueing is quite a nice change.
