Right, to start a line was drawn on the card up the centre, at the base the rule was used to allow for the scoring i.e. the first 20-30mm was folded up to give a defined starting point, when this was positioned at the base of the hull the line was positioned with that on the deck and the sides allowed to fold naturally around the prow, until they met the number 1 frame position (which coincidently is also at the base of the bow).
Using a pen I marked the number 1 frame position as well ran the pen around the top of the hull as a guide, using the rule, I marked the straight line between the number 1 frame and the bottom of the line, after cutting at least 20mm on the waste side of the lines, tried the card, then the rule was used with a Stanley knife along the No. 1 frame lines, checked it again.
Using evo-stick multi purpose contact adhesive applied to the hulls leading edge and along the centre line of the card, this was let for a couple of minutes before being fitted and pressed into place, it was left for a couple of minutes for the adhesive to get a grip.
I applied some contact adhesive to the top and bottom edges of the card and hull at the No. 1 frame and folded the card back - then I realised I had not created a way of holding them to the No.1 points, so out came the string and a frantic couple of minutes getting the string on and the points touching. I then decided to fill the rear edge of the right side with approximately 20mm wide strips of card along the outer edge, as you can see the rule eventually was used to keep this edge straight between the top and bottom of the hull, until the glue sticks, the space between the bow and the 20mm edge was filled with pieces of card cut into triangles and slid in.
Hopefully this will be strong enough to take any knocks in use, will probably look for a penatrating resin later, now will need to do the same for the other side, when the rule will be available, oh - pieces were cut to try and remove the low spot between no.1 and 2 frames (I think there was another frame between but its not defined to be able to see it).
Just released the right side and set up for the left - will see how that goes later on.
