Listen guys, I'm not playing around with a "Building toy" here,

When working - creating on this scale, you begin to demand the highest
preformance from all aspects of Lego.

Looks like toys to me. Really incredibly cool toys!
Tilman's post supporting my "Toy" claim mentioned how torsionally flimsy the
technic axles are. This could be used to take the backlash out of a gear train.
Pull out four 48 tooth gears, two 8 stud technic beams, and two 8 stud
technic rods. Mesh two of the 48 tooth gears by sliding them onto the rods,
and inserting the rods into the holes of one of the beams. Slide the second
beam over the other end of the rods and attach the remaining gears to the
open end of the rods. If everything is aligned properly, the gears will
rotate freely, and there will be a little bit of play. While the gears on
one side are meshed, disengage one of the gears on the otherside, rotate it
one tooth, and reengage. The gears no longer rotate as freely, but there is
no longer any backlash. Slip 3 or 4 teeth and the gear train begins to get
really stiff.
Nothing too brilliant, but it does the job. Probably not all that original
either, but it just occurred to me.

Sorry Eric. I certainly didn't mean the word "toy" to be derrogetory in any
way. Must be a cultural thing. My job is to create room sized "toys" which
weigh several tons, contain thousands of kilowatts of potential and/or
kinetic energy, and require special connections to local electrical
substations. When the creation is cool, it is referred to as a "toy". A
"machine" is a boring thing which does not stir the soul.
So once again I say of your inventions. Those are really cool toys! Take
it in the spirit it was given.

Mmmm, you are indeed respectful. Thanks, wow, So when we have made our
masterpieces we sit back and enjoy our toys, for our mind, body and soul
extensions. I like that! Very good.
Man's gotta have his toys ya know.
or
The more money the bigger the toys. etc....
Recv'd in the manner it was given.
I thank you.
Eric

Doh!. And I just took this in school (in fact, am going to write an exam which
this will appear on (methinks) thisafternoon. It's called "Locked Train", and
allows for more even power distribution across multiple gears in a gearbox.
Hmm...Now I suppose I am going to have to model a DDG 280's gearbox out of lego
as penance?

Good luck!!!
