A record of the renovation of a
Wooden Drascombe Longboat 'Otter'


20th January 2007. Laminated centreboard case sides.

As with the rudder case, I have applied three layers of glass cloth to the inside of the centreboard casing.

This photo shows the epoxy curing. As usual, I have used WEST System 105 Epoxy Resin and 205 Standard Hardener.

The method is to apply the resin to the wood, first, so that it soaks in and creates a bond.

With a layer of resin on the surface, the first piece of cloth is applied. The resin quickly soaks into the cloth. A squeegee is used to press the cloth down into the resin and remove excess resin.

More resin is added and the second piece of cloth applied. Then the third. After squeegeeing the pattern of the cloth can be seen.

When the resin is tacky the surplus cloth can be removed with a knife.

This picture shows a side after I have applied some filler (410 Microlight mixed with the resin.)

This files in the pattern of the cloth.

When I came back I found this. I had left about half a cup of resin mixed with filler that I had left over. Due to its large mass, it had overheated and set very quickly. I guess the air in the filler had expanded to give me a cappuccino!

Here is my first practice with a joint.(Resin plus 403 Microfibres)
