Small craft(10)

  The last step was making seats. We also call it as 'thwart'. It has to be strong level board for sitting and rowing or fishing. I prepared six wood blocks for supporting the thwarts. The inside of hull was not straight so it was not easy to make the right angle. Moreover, fitting the thwart into the right position was also very challenging and tricky. I spent quite long time to do that. However, once I understood how to do, it became an interesting job.  

 1. Firstly, decide the heights of bench and draw the line. Put down the bench on the position of sheer. Use a combination square and find the point 'A' which is the edge of ruler and the heights of the seat line. Draw another line on the side of the thwart 'B'. From this, we can know that 'B' is going to be the point 'A'.

  2. With a sliding bevel, find the angle of inside of hull at the point 'A'. To make sure, the handle of the sliding bevel has to be vertical from the centre line.

  3. Put the sliding bevel onto the thwart and draw the angle line from the point 'B'. Cut off along the line.

   Unfortunately, our thwarts had some problem. They did not stick perfectly, so I had to glue them again. I guess when we make epoxy resin, the amount of hardener was not enough due to pumping too fast.   While I was doing that job, I found that the middle of timber was not square so it became twisted and had a gap. To fix it, I had to sand them pretty much and after reparing it had become too thin. As a result, I had to attach another timber underneath the thwart. 



All three thwarts fitted really accuarately. They were all level!



I drilled on the thwart for fixing on. I used two different size of drills. One for pilot drill and one size bigger drill for making clean hole. It was my last job for making our small craft.

Other members did sealing with  epoxy timber sealer and timber sealer hardener (1:1 ratio)
