This may be more appropriate for lugnet.technic.  There has been postings or
listings of these before, but don't let that stop you.

You should add the turntable gears (outside is 56t, I think) somehow.  I
also would rather see the vertical in mixed fractions, such as 2-1/3 for "7"
for example.

A similar table is one that produces "diagonal" brace distances that work.
One of these was published recently.

So who is going to publish the super handbook on all these?  We really need
a "Technic Techniques" companion to the Mindstorms books.  Although things
like this are fairly trivial to compute, having a handy reference would be
nice.

(...) Something else I've thought would be handy would be a program which would take as inputs the desired positions of the input and output axles in a gear train and the desired gear ratio. Space constraints in the form of "bricks" blocking off (...) (24 years ago, 7-Nov-00, to lugnet.robotics)
  Re: Gear spacings.
 
(...) Well, I happen to work for a company which is just about to market a product for dealing with constraints - and this seems as a nice problem for making a small demo this weekend. Fuzziness and perfection must wait, though. I will post an URL (...) (24 years ago, 7-Nov-00, to lugnet.robotics)

  Gear spacings.
 
I've never seen a table of allowed spacings between gear wheels. (For example, two 40t gears will mesh nicely if spaced apart by three studs horizontally and 3 and one-third bricks vertically). I wrote a little program to compute all possible (...) (24 years ago, 6-Nov-00, to lugnet.robotics)
