I've just washed my old aluminium cold frame and a front glass panel has come loose.
I've struggled for ages to get the glass back in with the 'W' clips but I can only get one in and then there's no room at the other side to get the other one in.
I must have done it before a few years ago as I replaced some broken glass, but cannot imagine how I did it.
The other panels have four clips, but this one has only two (perhaps because it is so difficult)
Is there a trick to it or does it take two people to do it?
It's a Hall's coldframe but years old.
