After nearing completion of the upgrade of my H16 im having some big issues with my rudder castings.
Firstly the castings seem to have closed up , meaning that when i have gone to put the blades into the casting there is bearly enough room and this means that i have to force the rudders to rotate up and down ....How would i be best to open the casting up again without breaking them? (i believe they are really expensive!)

Secondly i seem to be having issues with the new one piece rudder gudgeons..the screws are interfering with the proper movement of the rudder casting from side to side...

Any ideas? Want to be sailing by this weekend ...and looking doubtful at present!

many thanks
