After a lot of air time one of my 3 Vapors got some repair on one leading edge but was still in great shape, but flying just after the sunset I didn't saw something on the ground and got a large tear between clear and red parts :'(
So I decided to go to a deep restoration to bring it back to new life, BTW I decided also to change colour of the red panel just because my other two Vapors are red and I wish something different. I think that sail was made with Texlon, a little hard to find here in Europe, and just to be easy and because I have some nice grape icarex I decided to go straight forward.
Also the rectangular shaped mylar for wingtips is hard to find so I used the standard modern 75g mylar. However in some pics of the last batches of Vapors I saw that also Prism used that
kind of mylar (if I'm not wrong).
I shot some pics of the working process and I'm happy to share them with you
But first of all I wish to thanks CaIke who helped me in getting the clear monofilm form an USA store that wasn't going to ship to Europe
.......and still now I don't guess why
Here are the pics in the working sequence:
The sail after cutting off the leading edges and wingtips
Signature and building date
After a passage with Autocad here are the templates
All the parts cut away and the assembly process: I used duoble side adhesive tape called "no seams" as Prism used in the original Vapor. I made 8mm and 3mm self adhesive dacron stripes
as the original one cut away from a 30mm wide dacron roll.
All parts put and sewn together
As for leading edge I used spinnaker, maybe Prism used a lighter stuff but I didn't bothered in searching it just because spinnaker works well IMHO.
Nose, apa cutting, standoffs holes, leading edge sewn: I used almost flat zigzag for leading edge because it's better and stronger than the original straight stitch, and a straight stitch
on leading edge around standoffs holes to avoid cuttings in the thread making holes.
Nose with frame inserted, the finally finished Vapor back to a new life, and a couple of pictures with it's fully original, mint brothers.
