Thank you Nigel,
Having got the top off now I can see that the leak is at the shelf on
the front of the tank where it sits on the mount. It appears that the
fibreglass had bonded to the tank and with movement caused a fracture
due to the stress. Having looked at the tank now which is very deformed
and reducing capacity, I am sure a "metal" one will be much superior.
Fortunately there are some very good craftsman around here so
fabrication will not be a problem. Not sure we will get to the same
volume as you have but will certainly look for more than I have now.
Will send some pic,s when all done.
Regards
Sue and Bill Sisley

your cardboard templates - the fuselage is partly conical in section so the
development will be an interesting shape. Choose a welder based on his ability
to weld alloy and don't fall into the trap I did of restricting yourself to
a CAA approved welder whose self-belief exceeded his ability!
