2) The bearing bushing must be removed from the foot stirrup before the
foot stirrup can be mounted on the lamination dummy. INFORMATION:
The bearing bushing can be easily pushed out of the foot stirrup
by means of the lamination dummy cover. Important! Set the bear­
ing bushing aside in a safe place and reinsert it in the foot stirrup
prior to final assembly of the orthosis.
3) Place the reinforced foot stirrup in the lamination dummy cover.
4) Set the cover onto the lower section of the lamination dummy and secure
it with the shoulder screw. The design of the cover causes it to be moved
into the neutral position.
5) Attach the lamination dummy to the plaster model by inserting the
shoulder screw through the cover, foot stirrup and lower section and
fastening it to the alignment adapter.
6) Seal the screws of the bar and dummy with Plastaband.
7) Laminate the orthosis according to the patient's needs.
8) After the laminate hardens, use a knife to cut free the lamination dummy
and remove it.
9) Remove the Plastaband from the screws.
10) Remove the two countersunk head screws of the lamination bar.
11) Loosen the lamination dummy screws and remove the cover.
12) Use the oscillating saw to expose the edges for removal.
13) Remove the components from the plaster.

Mounting the axial washers
1) Select and insert the axial washers (see the following table for the thick­
ness of the axial washers).
2) Optimise the movement of the orthosis joint by replacing the axial wash­
ers step-by-step: Use thicker washers if there is play in the medial/lateral
direction, thinner washers if there is resistance in plantar flexion/dorsal
extension.
