Glazing Bars In, Glazing Bars Out...

I wasn't happy with the glazing bars this morning, on the left as you look at the photo. I'd put the right hand side glazing bars in and noticed that the left hand side looked misshapen, the top of the window had been pushed upwards & was on the wonk. You can see what I mean in the photo. So I've taken them out, now got to adjust the length of the bars, and refit them. my need to find a clamp. The things we do to get it perfect.
