I agree.
I`m not sure how supposedly grown men can make something so simple, so difficult.
You pictured the bearing on the wrong side of the doughnut or rubber cushion or whatever you want to call it.
And you will not need spring clamps either.
I always try to make sure that the posts I make are correct and as I said, if I am wrong then I am the first to say okay fine. I am just trying to clarify a couple of the things you have posted that contradict what I believe, but you crack on.
