Tony Renshaw asked about Pip Pin Cover details. I went to a plumbers 
merchants and obtained a couple of fittings for the 1.5 inch plastic pipes 
that had screw in blanking plugs. I turned them on a lathe so that the plugs 
go down to a flush finish and then after lining the hole with BID, set the 
fittings in with flox. I have got two small holes in the tops and a small 
tool that I can insert to twist them off. John Tye has got a similar 
arrangement on his Europa but using some very small fittings that look less 
than 1 inch diameter. Another system that I saw at Cranfield which was 
particularly neat was a small flat, hinged at the front and held down at the 
back with a small butterfly Dzus fastener.
Hope all this is of help, David Watts.
