And now I've finished Frame 123.5.
These are the 3 frames I have done so far.
Frames 140 & 156.5 are the same size. The rest of the frames are smaller.
I'm close to finishing frame 107 now. There are 17 main rings. I'm not going to bother with the intermediate rings at this scale.
The tail rings will be interesting, though. and the nose ring is attached to the intermediate ring behind it.
Cheers,
