Chalk up another pano roof trouble and fix

[Lamby]

Sorry, I am ham-fisted, when I say precision, I guess I am saying, "Don't just hit it with a big hammer!" as I use myself as a benchmark. I took maybe 1 minute of concentration each side to remove the small plastic triangle and make sure I didnt touch the runner with the blade then I rubbed some motorcycle chainwax on the runners (dont use WD40 its too thin) and it was so much easier to close. As said, I have no patience at all so a minute with the Dremel was like an hour for me. After all the work I got the house hoover out and hoovered all the rubbish out of the gutters as well. Tried to do a good job on it then 3 weeks later I was back in the roof refitting all the anti rattle tape thinking to myself... why the heck didnt I do this at the time of doing the repair. Anyways.....
