[J1, Bogen 3] with the gold-printed side
downwards onto your worktop. Glue the
inner hub parts 1 to 3 [J2 to 4, Bogen 3]
together, so they form a block and glue
this block on the centre of the rim. Make
sure that the holes in the centre that will
take the axle are exactly aligned and stay
free from glue. You can check this before
the glue sets by pushing the rim onto the
axle.
Step 34: Glue the inner parts 1 to 4 [J5 to
8, Bogen 3] onto the back of the rim so
that they make up a complete ring. The
inner edge of the rim (between the
spokes) should be flush with the inner
edge of this ring. After the glue has set,
glue a second layer of inner parts (J9 to
12, Bogen 3] on top of the ring, with the
joints slightly shifted. Again wait till the
glue has set, then glue the third layer of
inner parts [J13 to 16, Bogen 3] on top.
Check several times in between that the
half-wheel doesnʼt warp.
Step 35: Glue the outer hubs 1 to 3 [J17
to 19, Bogen 3] together, making sure that
they are completely flush, and with the
gold-printed disc on top. Donʼt glue the
stack to the rim yet.

The Driving Wheel 2
Step 36: Repeat the procedures from
Chapter J to construct the second half-
wheel. The parts are all on Bogen 4 and
have the same numbers, except that the
letter J is replaced by K.
Questions and Answers
The Ferris Wheel doesnʼt turn because the Steam Engine runs too slowly. What can I do?
✴ Make sure that the Steam Engine is properly adjusted. Only with optimal adjustment will it run fast enough and supply enough power
to operate the Ferris Wheel. The speed of the Steam Engine is a good indicator for the correct adjustment. Check the manual for the
Steam Engine for hints of how to set it up properly.
The Ferris Wheel still doesnʼt turn although the Steam Engine runs properly. What can I do?
✴ Remove the driving belt and check that the Ferris Wheel turns without any noticeable friction and that all gondolas can swing freely
around their axles. Check that the axle of the Ferris Wheel can turn freely in its bearings. The silicone tubes should not rub against
the bearings! Sometimes a small drop of oil helps.
Can I put small figures in the gondolas?
✴ Of course! But you have to make sure that the weight of the figures in each opposite gondola is exactly the same.

Step 37: Glue the two half-wheels back to
back with the spokes being aligned. Make
sure that the holes in the centre are
aligned and check this by sticking the
wheel onto the axle.
Step 38: Now glue the two outer hubs
onto the driving wheel and stick it onto the
axle before the glue has set. This way you
can be certain that the wheel doesnʼt
wobble. After the glue has set, push the
last piece of silicone tubing onto the end
of the axle and push it together with the
one opposite firmly against the driving
wheel to lock it on the axle.
The ferris wheel is now complete. It
should turn quite freely so that it will turn a
few times on its own after pushing it once.
No excessive friction should be apparent
at any point of the rotation.
Chapter L
The Small Driving Wheel
The small driving wheel only has one rim,
we use the hub of the steam engineʼs fly
wheel as the other one.
Step 39: Glue the 6 inner parts of the
small driving wheel [L1 to 3, Bogen 1; and
L4 to 6, Bogen 2] together to form one
block. Again make sure that the holes in
the centre are exactly flush, which is a bit
tricky since the parts are quite small.
Step 40: Glue the two rim parts [L7,
Bogen 1; and L8, Bogen 2] flush onto
each other and then the block made from
the 6 inner parts onto the grey glue mark.

Step 41: Remove the outer piece of
silicone tubing holding the fly wheel on the
crank shaft of the steam engine and fit the
small driving wheel, the smaller block with
the 6 inner parts first. Then secure the
driving wheel in place with the silicone
tube pushing firmly against it.
Tip: If the free end of the crank shaft isnʼt
long enough for the driving wheel to be
fitted, just move all other silicone tubes on
the crank shaft a bit.
Step 42: Operating the Ferris Wheel:
Start up the Steam Engine and stand the
ferris wheel next to it so that the two
driving wheels are exactly in line. Put the
drive belt (rubber band) over both wheels
and pull the Ferris Wheel away from the
Steam Engine until the rubber band just
starts to become tight.
And off we go!!
We wish you lots of fun with your Ferris
Wheel. Maybe you have other ideas for
models that can be driven by the steam
engine? Give it a try and let us know
about it. We are looking forward to your
photos and videos!
