I've noticed something I didn't expect, the strips are hard to fit on the top then the bottom. The bottom you had a much larger angle to bend the strips on, but they didn't have the same degree of turn. Also, then you try to shave the ends to make a tight fit, and end up have to shave all 4 sides, to make it even. The last couple piece's I did tonight, weren't near as bad, so i think the progress may start to pick up again. Until I start to strip to other side of the top, lol.
Anyway, a few pics of the progress.
