Hi there,

I've started to construct things I would never imagined • building as a kid --
things that might strain or even break parts.  I've • seen some examples of these
types of building on various AFOL web pages, and • perhaps so have you.

For example, I've built a 45-degree, 7-stud brick wall • that runs across the
diagonal described by going five studs over and five • down.  Several of the
standard Lego octagonal plates have a 5 X 5 cutout at • the edge, such as...

http://www.lugnet.com/cad/ldraw/parts/ref/search.cgi?q= • 6106

...and this is a nice way to make a wall that covers • that space.  I've found
that Ed Boxer built this same wall for his Crown • Cathedral model.

http://www.geocities.com/~edboxer/crown.html

We both seem happy enough with it.  I've also built a • 14-stud long wall that
spans the space covered by going ten studs over and ten • studs down.  What's the
big deal?  Well, the math says that we have to be • stretching the parts to make
these constructions work.  The actual distance between • a point (0,0) and point
(5,5) is the square root of 50, which is not seven. • It's about 7.071.  That
means that the bricks used to cover that diagonal must • be stretching, though by
just a bit.  The 14-stud wall should actually be 14.142 • studs long.

I know it's possible to warp a plate -- I have a warped • 4 X 6 plate from some
used parts I inherited.  I have no idea how it got that • way.

Moving on to potentially more serious consequences: • I've started to build models
that put quite a bit of weight on hinge bricks, • turntables, and hinge plates.
In one case, I have two plates, tilted somewhat to form • a dihedral angle, that
meet on a knife-edge.  To be sure, it's a fairly long • knife-edge, but the model
is heavy.

Eric Harshbarger described destroying some parts when • he was experimenting with
his grandfather clock.

http://www.ericharshbarger.org/lego/clock.html

He describes breaking the chain parts, which is not • really so surprising.  I'm
really more interested in the kinds of things that • resulted in, for example, a
broken gear, and a Technic axle getting twisted to the • point of unusability:

How far can you push Lego go before it begs for mercy? • Share your war stories!

  here's one for the record books : lego death by
photography!  the last image on the craigo-lego page of
my site :

http://community-2.webtv.net/anonymouseye/craigolego/

  ... was taken after a long night of scanning on the un-air-conditioned
third floor of a building in macon, ga in 90 degree july heat. the weird
lighting effect was achieved by shining a 75 watt bulb directly into the
scanner behind the models,  the scanner glass was pretty hot after spending
a few hours making other images and combined with everything else, melted
half a 1x3 brown plate and half of the black hinge in the orange dragonfly.
the trans orange grille tile which was connected to the melted end of the
1x3 was unharmed. i still have the half melted 1x3, but lost the hinge
somewhere.
