It's pretty simple; select two gears and a tolerance and you get a table

That is very well implemented indeed! Something I think would be interesting
would be a measure of the strength of a particular combination before the
gears either crunch or break - for example I am sure that the strongest
combination of gears is two sixteen teeth ones in a perfect mesh, and I
suspect that even two sixteen gears in an imperfect mesh would be stronger
than a setup involving one or more 8 tooth gears in a perfect mesh.

Of course, this would mean testing gears to destruction with a torque
measuring device which may not be kosher for everyone :-)

I think creating dissagreement is the quickest and most surefire way of
generating a reply, consider this proof :-).

I would think a pair 40 tooths gears would be the strongest set up. I've
never broken either combination so I have no proof.

I do find however that you can't get a perfect mesh with sixteen tooth
gears, they tend to bind. They must be slightly too large. I'm sure a less
than a millimetre correction would cure the problem.

I also think the second weakest gear is the 24 tooth crown gear (the one you
use for meshing at 90 degrees). Are the newer bevel gears any good,
strenghtwise?

(...) In the case of 16 and 40 tooth gears it is not so much the teeth breaking I was thinking of, rather it is the strength of the centre connection of the gear to the axle. The 16 teeth ones definitely are the strongest in this department, and (...) (23 years ago, 5-Nov-01, to lugnet.technic)

(...) There are two versions of the 24 tooth crown wheel too - on the older version the part of the tooth which stood above the main body of the gear was much smaller, and I have several with broken teeth 8?( The newer ones are much stronger, but (...) (23 years ago, 6-Nov-01, to lugnet.technic)
