Very helpful, and thanks, but might I suggest you get a camera with a higher dynamic range, or film the fiddly bits indoors with good lighting. I had trouble trying to work out what you were doing when you were outdoors waving the blade around in front of your dark shirt .
Again very good advice, I didn't think of that either. If you cut the old rubber to get it out, it would probably be easier to get the caps off with the old rubber not being in the way, as it can be a bit stiff getting the caps ends off.
