Trying to get the correct angle is a faff. Bits of cardboard, lines on screen etc etc. There is so much tolerance in the system including the position of the wiper wheel boxes so determining angles is difficult, my poor geometry skills not helping.
My original wiper gear was 130 and blades dropped off the screen bottom big time (this may not have been helped by having a drop down screen which may have altered angles but I cannot be sure). I went to 105 but 110 better. For me 115 is too much
I did work out a way of determining the gear but the measurements were so small with so much play in the system that accuracy was questionable (if you want my notes in this regard just pm me). So all a bit trial of error In the end.
Sorry I cannot be more specific for you.
Thanks Geof My experience was very similar to yours but as the new blades that Peter has had made only just go off the bottom on the middle and near side, and after playing around with bits of card and string, I am hoping 10 degrees less will do it. I was wary of going too small as it would decrease the wipe area on Mrs Deejay’s side and her eye-level is more aligned with the bottom of the screen rather than the upper portion.
