You can get half round brass strip from ebay too. The depth of the brass strip at its deepest point is probably the key thing – you would likely need to file down the sides to keep to the profile of the board. As far as I know having looked into all this with respect to making a new centreboard, there is no spec for any strips you may add, just…[Read more]
There is a helpful article on the rooster sailing site regarding the plastic super shute bailers:
Thanks for responding to the original question. The point about a tight fitting board is that in the event of it jamming there is no means of freeing it from above and if singlehanded that could be a showstopper. You can avoid circumstances where it may jam, and indeed I will, but it seems sensible to have a means of solving it as circumstances…[Read more]
I am sure tongue and groove would be stronger if a good tight fit. It might also compensate for any slight imperfections on the adjoining edges, if there are any.
I think the PU glue used on the rudder was Wurth. However I have subsequently used this one with similar results:
The PU glues seem to work best…[Read more]
Thank you very much – that is very useful – I will use that method.
I made the rudder blade as follows – laminated strips of sapele (from 25mm board) around 75mm in width, each alternate strip flipped in order that any warping would be cancelled out by adjacent strips (seems to be stable after 2 years or so). I have a friend who is a…[Read more]
I am planning to make a new centreboard over the winter but am after some advice as to the best finished thickness to choose within the range 17-21mm. My current CB is 21mm (perhaps even a little more in places) and is a very close fit to the case. This would seem to be a good thing (it is a snug fit but still free to move). The problem that…[Read more]
I did what you did and then found that you don’t need a pump – just blow into the end to get it up to pressure and put your thumb over it for 30 seconds. The pump just complicates things I think (although my tubing may be greater diameter than yours, so easier to do).
It is also then possible to do the test the other way – suck out some…[Read more]
