Again, it may be parallax (or, it may be late...), but the following do not appear to me to be "smooth progressions", whether simple or exponential:
1) Section 2, vertically
2) Section 4, horizontally
3) Section 4, vertically
Of course I don't know what the thing is supposed to look like, in the first place, but this is where large, plotted paper (or cardboard) templates are useful as gauges. Maybe plot and gauge the inside of the curve, so differences would be easier to spot (if it matters...).
It's very easy to cross a line with a hand-held power saw, and a snapped line can be fairly wide (relatively speaking, here), to begin with. If this proves to be an issue, Japanese-type ink lines are quite narrow and visually sharp. If/when the line is critical, one can always "leave the line", then plane or sand back to it with a disk sander (experts only...), for greater control. |
