Replacing the components of the bottom clamp assembly
Introduction
1 To dismantle the bottom clamp it is necessary to remove the oval leg.
NOTE: Construction of the 'Baby-Legs' leg assembly precludes the replacement of the bottom
clamp components.
The design of the bottom clamp has been modified twice.
The knobs changed from "one stop" to "two stop" and the shaft thread from M4 to M5. Two
5 mm grubscrews were fitted. Later the shaft was fitted with a locking thread insert and the
grubscrews were changed to 1 x M5 x 10 mm.
