I have discovered a work-around solution to point 2.
The gear shapes were "cylinder"; they are now "convexhull" which provides for
clean,
accurate meshing of involute spur gears without repulsion. A “powered”
hinge or
motor control must be joined, in opposite directions, to each gear. The most-
accurate representation comes from assigning identical "accel" and "damp"
values to
each hinge/motor control. Note also that a “driver” gear will not affect
a “follower” gear – both gears must be powered.

I vote this up, small geometries do not work.
Create a cube, 1" x 2" x 4". Group, set as box, and run. The cube will fall
into the abyss as expected.
Now scale the cube by 0.5 and run. The cube will remain where it is.
Scale the cube back up by 2 and run. The cube will once again fall into the
abyss.
Further experiments:
A 1 x 2 x 2 cube falls. (4 cu in)
A 1/2 x 2 x 2 cube does not fall. (2 cu in)
A 1 x 1 x 2 cube does not fall. (2 cu in)
A 1 x 1 x 4 cube falls. (4 cu in)
A 1 x 1 x 3 cube does not fall. (3 cu in)
A 1 x 1 x 3 3/8 cube does not fall (3 3/8 cu in)
A 1 x 1 x 3 3/4 cube falls. (3 3/4 cu in)
A 1 x 1 x 3 9/16 cube does not fall (3 9/16 cu in)
The cutoff appears to be somewhere between 3 and 4 cubic inches.

Has there been any updates on this issue? This makes it incredibly difficult to
create a design (to scale). If there is an update or workaround would someone
post it to this thread?

I used the UI to change the density of the object from 0.2 to 2.0 and it seems
to have resolved the issue

I can confirm the small geometry error. I can also confirm that density of the
object has something to do with it. Changing it to 2.0 seemed to help but only
for certain geometry sizes.

Is this going to be changed in the near future? Or at least addressed?

What seemed to work for me is setting "worldscale" (Top menu:
Plugins>SketchyPhysics>Physics Settings) to 0.2.
Maybe someone can elucidate ?
