Mark a second point at 9 cm left to the indicated middle
of the pipe. The second market point must correspond
with the mark on the disk. Here the first bend will begin.
To start bending we use a bending-claw m with
accessory cylinder K plus half-shaft. Put cylinder K
half-shaft into the third hole of bending-claw m.
Slip the bending-claw m over the spindle.
(disk G and pipe are in between the claw)
Fix ring O over the spindle and lock it up with
the 2 doweled joints.
