Hi Chriss
I have been trying to make mine automatic/electric.
so I have taken the mechanism out and in several times these pass months.
I Found that loosening the sides channels both the one on the triangular glass and the other side makes the glass easier to handle.
Make sure you mark with a marker the possition of the screws before loosening them.
As you already know the glass goes in and out on an angle back side up.
you might try to take out the rivets on the winder to see if it is fixable
.and check ebay sometimes you can get a good deal.
Rimmer is also having a good sale take a look it might be worth it.
and don't forget to buy neospouring and band aids for the new collection of cuts you will be receiving.[B)]
