4. These parts now need

to be arranged as in

diagram 2 where they

should be welded in

position. As can be seen

from this 4 pieces of Part

B should be cut at 45

degree angles.

5. The next stage is the

making of the 8 rim

clamps which will hold the

wheel rim. Firstly 8mm

clearance holes need to be

drilled and equal distance

apart (150 mm).

These holes will allow the jig

to make different size wheels.

6. The heads of eight 20mm bolts

are cut off and the handles (Part G)

are welded at one end.

6. A 20 mm nut is then welded to

the end of the tube (Part H)

7. Following this, Parts E and F are

welded together and then welded to

Part C (see tech drawing WJ – 02

for positioning dimensions).

8. The rim clamps are now ready to Diagram 4. A 3-D Model of the Hub Clamp

be screwed in place on the frame.

Obviously in the same position on

each leg although it will be quite

apparent if one is in the wrong

place.

9. The central locking bolt can

now be put in the centre of the

frame. First of all a hole is burned

in the metal with the welder that

allows the 30 mm threaded bar

(Part K) to fit inside. The

threaded bar is then welded in

position (90 degrees to the base).

and M are
