Required tools and materials:
>
623T3=8 or 623T3=10 perlon stockinette, 81A1=8 or 81A1=10 tube
sock, 616B1=25x* carbon fibre cloth strap, 616G2 carbon UD hose,
616G15 carbon fibre woven hose, 99B81=100X19X5 PVA bag,

1) Cut 3 pieces of perlon stockinette (each 2 times the length of the plaster
model).
2) Pull a perlon stockinette over the plaster model to the edge. Tie off the
second half of the perlon stockinette with the string and fold it over the
plaster model (see fig. 9).
3) Pull the 2 other pieces of perlon stockinette over the plaster model the
same way.
4) Expose the valve dummy using a scalpel (see fig. 10).
5) Wrap string around the valve dummy and tie the perlon stockinette off
tight in the distal groove of the cylinder body (see fig. 11).
6) INFORMATION: Tie this off tight so the system is airtight after the
lamination process.
Tie off the 6 layers of perlon stockinette in the large undercut of the cylin­
der body so they are up against the cylinder body (see fig. 12).
7) Position a layer of carbon fibre cloth strap from the medial condyle over
the cylinder body to the lateral condyle (see fig. 13).
8) Position a layer of carbon fibre cloth strap from the MPT (mid-patella-ten­
don) point over the cylinder body to the opening for the back of the knee
(see fig. 14).
9) Position a layer of carbon fibre cloth strap circularly around at the height
of the MPT (mid-patella-tendon) point (see fig. 15).
10) Pull a tube sock over the plaster model.
11) Expose the valve dummy.
12) Wrap string around the valve dummy and tie the tube sock off tight in the
distal groove of the cylinder body (see fig. 16).
13) With a perlon string, tie the tube sock off tight in the undercut of the cyl­
inder body (see fig. 17).
