Time to get the screen template underway! After a trip to Homebase i found a piece of polycarbonate 2mm sheet that was reduced because the corner was knocked off .
I used a hotmelt glue gun to glue on the offcuts to make up the length as the piece of polycarb was not large enough.
Carefully scribing the polycarb to fit the deck first and then cutting the top to match the frame.
The Jigsaw was fitted with a metal cutting blade and the fastest speed setting which almost melted the polycarb as it cut, then i cleaned up the cut edge with a low angle block plane.
I had to reshape the frame to get the right angle for the screen to fit nicely.
I left my windscreen frame out over winter and it developed a black mold that i i tried to shift by sanding but with no luck. I was strugling to find a solution to this problem when my Godfather Ron Brookes suggested that i try some Oxalic Acid , so have just sent off for some and will let you all know how i get on .
