I also wondered why they used this gear in the backhoe-model when I built it
the first time. If I should have constructed it myself, I would also have
used the normal bevel or crown gears. The angle between the gears in the
model is fixed, and there is suport behind the gears so there sould be no
problem with the normal gears getting out of possitions. Another thing is
that there is no heavy force that this gears should drive so they do not
need to be very strong. There is only one drawback with this gear, it is not
very accurate, it is too much space between the "tooths".
The only thing that comes to mind is that LEGO probably tries to show us
builders that there are many ways to use a brick. This was a new thing to
me, and maybe I will use this in another setting later, now I know how to do
it.
I also read in the "technic beam/brick" tread and think it is the same way
with this new bricks that LEGO is making, they are not trying to make new
bricks ONLY because some of them maybe "looks cooler". I think they are
trying to give us more options to build with. I think these new bricks are
great, but since I'm an old Technic fan with over 20 years experience with
the normal gears and studed bricks I have a hard time to get used to new
ways of building. But I try...

| I'm thinking that given the compact design of the backhoe digger, it's been used in this instance to perhaps get around the fact that the three-cylinder engine might get in the way. Trying to remember the instructions from memory (at work right (...) (21 years ago, 29-Jan-04, to lugnet.technic)
