A compound staff must be equipped with a foot to dampen shock that may be transferred to the art piece. Particular attention was paid to the design and machining of the foot.
First, a 7/16" cold
roll steel shaft is inserted into the staff end, and is secured with a 3/16" brass pin. A brass taper is machined to accept the diameter of the compression spring.
On the foot end, a 1" diameter cold roll piston retains the
spring via a recessed stainless steel hex cap nut. The piston provides 20 mm of travel. The spring has 12 active coils, and features a machined aluminum sleeve. (Rubber end cap not shown).
Yes, this is a tremendously, over-zealous,
and over-engineered component. What can I say, I was on a roll.
