I did something similar for my ASW 20 years ago, by adding a 1"
extension to one pin to make the tapered portion longer. It helped just
as JJ describes.

Nowadays, a good alternative is the eccentric cam tool available from
Cobra. You put the tool in a pin hole on one side, turn it 90 degrees to
draw the wings together and align them, place a wing pin in the other
hole, remove the tool and put in the second pin.

I use it occasionally on my ASH 26 E when I don't get the things quite
right the first time, as it's quicker and easier me than fiddling with
my particular set of dollies and wings. You can make your own easily if
you can machine things, as a friend did for me before the Cobra unit was
available.

I have always had problems in getting the first main wing pin started.
Recently I did some checking and found that not all main wing pins are
created equal. Some come with generous tapered ends and others come
with a very sharp slope or no taper at all. My Genesis 2, for example
has a 4:1 taper while most Schempp-Hirth equipment will be sporting a
generous 10:1 taper. I reasoned the 10:1 slope would make it much
easier to get that troublesome first pin started.
