[R-390] need help with intermittent gear aka Geneva gear

[Phil Mills]

I just can't seem to get this one right....I've got all the rest of
the gear train set up and aligned but I can't seem to get the
intermittent gear on the bandswitch to work correctly and the
drawing in the manual is not much help.  I know that some of
the teeth on the little gear between the intermittent gear and
the bandswitch gear are longer than others and I suspect that
these are not in sync with whatever on the intermittent gear.
I have been told that these longer teeth are supposed to run
up/down with the bandswitch in the 7 mc position but I've
tried this in conjunction with what I think is the correct setup
for the intermittent gear according to the manual drawing.

I've been working with this so much that I can go from complete
rf deck on the bench down to the intermittent gear and back 
fully reassembled in less that 15 minutes which shows
that I've had a lot of practice :-)

Can anyone offer any help or instructions on how to get these
gears positioned so they work correctly?

thanks, Phil   W5BVB
