The document is an assembly manual for building a transport rollator. It provides 32 detailed steps to construct the rollator, which includes milling, cutting, gluing, and assembling various wood, metal, and plastic parts. The overall cost to build the rollator is €180 and it takes approximately 2 days to complete. Precise tools like a CNC milling machine are used to shape some parts, while other pieces like the handle and pedal assembly involve additional fabrication steps like welding, painting, and finishing. Upon completing all 32 steps, the finished rollator is made up of conductors, a supporting board, and triangles to provide a rolling walker for transportation.

5. 1 TRANSPORTROLLATOR 1.8
DESCRIPTION
Mill the platform with a CNC woodworking
machine out of a Volkern board (700 x 450 x 6
mm).
HINT: make sure your cutters are freshly
sharpened, because the Volkern material is very
hard. Also do not mill out in one step, but take
something like 3 steps to complete the whole
thickness.

7. 2 TRANSPORTROLLATOR 1.8
DESCRIPTION
Find an old bike and take off one of the pedals.
Start adjusting it with your grinding disc to
achieve the right length as can be found on the
technical drawing. Weld an inox cylinder at one
end and two washers (M16) at the other end
(where the pedal used to be). Refine the welds
with a round file. The outer washer has two
slots, made with a metalsaw.

DESCRIPTION
Paint the adjusted bike pedal black, when you’re
happy about the results you achieved with the
filler. Don’t paint the center piece of the
axis, this will be mounted into a support later on
to turn the handle. Because the paint wouldn’t
stand the friction, we tape this area while
painting.

DESCRIPTION
Adjust a Gardena connection piece (female:
connection between hose and tap) with a cutter.
Cut of the part where the hose should come and
remove the upstanding edge (see picture). This
will make sure you can move the grey part from
the orange part with maximum distance.

16. 11 TRANSPORTROLLATOR 1.8
DESCRIPTION
Paint the handle black. Then join the handle to
the gardena piece with a long screw (6 x
100mm). The head of the screw gets stuck on
the nozzle because of the tensile strain. Now
complete the part with the white rope. Make a
loop at the end and fix the rope in the two slots
of the washer (see next slide).

€ 0.31 (milling) + €0.45 (all ayous)
19. 13 TRANSPORTROLLATOR 1.8
DESCRIPTION
Finish the first beam by gluing small pieces at the
end of the opstanding cubes. Because this is
impossible to achieve with the CNC machine we
do this now. When a CNC machine is not an easy
accessible tool, you can make this whole part
with this technique. Just glue all the upstanding
part onto a regular beam. This will be less
precise of course .

21. 15 TRANSPORTROLLATOR 1.8
DESCRIPTION
Make the pieces you need to make a swallow’s
tail in Volkern material. Put the circular saw
under an angle to achieve the right parts (2outer
parts which will be mounted on the conductor
and 1 center part which will be mounted on the
turning board later on). Sand the outer white
layers off to get the black colour out. To do this
in a controlled way, it is best to use a sanding
machine.
HINT: Again make sure the blade of the circular
saw is sharp!

23. 17 TRANSPORTROLLATOR 1.8
DESCRIPTION
Make drilling holes into the second beam where
later on the swallow’s tail will be mounted.
Make a small hole (diam. 4mm) all the way
through and a bigger hole (diam. 9mm) till about
15mm from the end (= the side you just covered
with formica). This way we can draw the pieces
of Volkern for the swallow’s tail from the other
side. By doing this no screws will be visible. So
drill a hole of 3mm into the pieces of volkern and
screw them onto the beam.

DESCRIPTION
Now we can finish the second beam completely
with formica. Afterwards glue the aluminium
profile into the beam with all-round glue.

large, afterwards you can sand them. For more
difficult parts you can use a cutter to complete
the form.

32. 26 TRANSPORTROLLATOR 1.8
DESCRIPTION
All steps from 12 till 23 have to be done
twice, because we need two conductors. But
keep in mind they have to be mirror images. So
very carefully watch every step, so you can
screw them together in the right way (step 24).
HINT: When you apply formica onto the ayous
wood, always garantee adhesion with pressure
(see picture).

Now we start making the support. Begin with
covering one side of a multiplex board with
formica (see technique in previous steps). Drill a
hole with diameter 4mm on the right place.
Make a second hole for the head of the screw
ont the other side of the formica (not all the way
through). Then insert the closet door handle and
screw it tight (door handle on the side of the
formica).
