1) Prepare for fabrication of the prosthetic socket (see Page 24).
2) Cut 3 pieces of perlon stockinette (each twice the length of the plaster
model).
3) Pull a perlon stockinette over the plaster model to the edge. Tie off the
second half of the perlon stockinette and fold it over the plaster model
(see fig. 10).
4) Pull the 2 other pieces of perlon stockinette over the plaster model the
same way.
5) Expose the valve dummy using a scalpel (see fig. 11).
6) Wrap string around the valve dummy and tie the perlon stockinette off
tightly in the distal groove of the cylinder body (see fig. 12).
7) INFORMATION: Tie this off tightly so the system is airtight after
the lamination process.
Tie off the 6 layers of erlon stockinette in the undercut of the cylinder
body so they are up against the cylinder body (see fig. 13).
8) Position a layer of carbon fibre tape from the medial condyle over the cyl­
inder body to the lateral condyle (see fig. 14).
9) Position a layer of carbon fibre tape from the MPT (mid-patella-tendon)
point over the cylinder body to the opening for the back of the knee (see
fig. 15).
10) Position a layer of carbon fibre tape circularly at the height of the MPT
(mid-patella-tendon) point (see fig. 16).
11) Pull a nylon stockinette over the plaster model.
12) Expose the valve dummy.
13) Wrap string around the valve dummy and tie the nylon stockinette off
tightly in the distal groove of the cylinder body (see fig. 17).
14) Tie the nylon stockinette off tightly in the undercut of the cylinder body
with perlon string (see fig. 18).
15) Cut off a piece of woven carbon fibre stockinette (1.3 times the length of
the plaster model).
16) Pull the woven carbon fibre stockinette over the plaster model to the
edge (see fig. 19).
17) Tie off the excess woven carbon fibre stockinette at the distal end and
pull it over the plaster model (see fig. 20).
