Bow pole tube

At first I thought of making the carbon bow pole by myself, also as a kind of exercise for making the carbon mast and boom in future. But for practical reasons I decided to buy a custom made bow pole, to save on time and to have a look in the kitchen of a professional carbon mast maker. Thomas Whilkes of Ceilidh Composite Technologies (http://www.carbonmasts.com/), the maker of the carbon bow pole, was so kind to discuss some ins and outs with me about making a carbon mast and the ideas I have to do this by myself.

The bow pole has been made in a female mould with carbon pre-pegs. The only thing I still have to do is making the attachment points for screacher and spinnaker. The bow pole is retractable and slides through a bow pole tube. To make the bow pole tube I thought I needed the bow pole as a mould, but in hindsight it was not necessary to buy the bow pole in this stage, as the outside diameter is exact the same as a 125mm pvc drain pipe. So, instead of the carbon tube I used a pvc drain pipe as a mould for the bow pole tube. With 7 layers of wallpaper I increased the diameter to 128mm for the easy gliding of the bow pole. The mould is finished with two layers of plastic film and a teflon coat between the films to be able to release the glassfibre bow pole tube from the mould.

There are also some new photo’s in the picture gallery of the sterntube and external laminate.
