4 Rotations in 2:44, 2:1 pendulum, TMAX-400
Re-do these with TMAX-100 and no wobble.

With BAFFLE:
1 Rotation in 2:44, 2:1 pendulum swinging N-S, TMAX-400
1 Rotation in 2:44, 2:1 pendulum, various positions, TMAX-400
With BAFFLE:
Re-do some of the previous images (2:1 Pendulum, various positions, one rotation in 2:44) with TMAX-100 and more exposure (9.5 ma)
Add the BAFFLE
Try just one with 2:1 Pendulum but swinging N-S
Work more with the gimbals, TMAX-100, and more exposure
WIGGLE problem solved as of 150J
Adjust the gimbles so there is no difference in periods N-S and E-W, and try some freehand starts
The turntable has been redesigned so that one complete rotation is now 10:48
These were done with the 5:3 pendulum with a N-S start at the tail end of the 2014-15 season
Belts tightened after 154F, and lower pivot imobilized after 154G - jerky problem fixed!
Continuing with the slow (10:50) turntable at the end of the 2015-15 season
These were done with the 4:3 pendulum
