Hi Diede, yes your right the "O" ring would not be suitable for purpose, will go along your with your advice,
This model is very similar in styling to my first model MSC sprite but much grander (I do like this style), I have a tendency to over engineer things and the Sprite turned out to be top heavy requiring radical surgery to correct, one of the reasons was that I clad the superstructure in 2mm mahogany planking and solid brass fittings, looks great with 16 coats of clear varnish…….yes 16……..see what I mean lol,
As I will be cladding Siadwell with the same but 1mm this time, the new incarnation of Siadwell has a greatly reduced superstructure, so I should not have the same problem, whilst Paul's design is much classier,the new version does look beefier, well it does to me,
Beefier is possibly not the right word but you get my drift.
Ralph.
