Well, a productive 48 hours......Part I
It is well known that Sammio cockpits are not the place for a tape measure or a straight edge.......
Front.....
Rear......
The crossmeber for the roll hoops makes for a good datum point so I marked a cockpit opening that is within 5mm of being true front-to-back and side-to-side.
and used a bit of hose to get the corner radii looking right (150mm for front and 180mm for rear).
I then drilled holes from above along the outline so that I could see the lines from the inside of the shell.,,,,and cut off the unwanted return.......
and put some formers in place.
I'd planned to use some uPVC strips to provide a former inside but I couldn't get a constant radius with a heat-gun or steam.
So I used 25mm high closed-cell foam. It is 10mm wide so you can get a good contact with the hot glue gun. I parcel-taped the foam before glueing, and then hit it with some gelcoat.
Part II to follow shortly.
