Dang! I salvage the smallest and strangest of little things which fall into the category of "Oh that might be useful one day" ... I have never used this piece of hardware myself, perhaps someone else can make use of it
What on earth is this bright, shiny thing?
Solid brass, round and with a long grub screw at one end with a small hole (non-threaded) nearby. This brass piece of hardware fits onto a very small diameter motor shaft, at a right angle! The grub screw holds this brass piece securely onto the shaft. As the motor shaft rotates, this piece of Brass really causes the rotational forces of the shaft to go heywire! The motor was mounted on a suspended plate (rubber feet) and as the motor shaft is rotating, the plate moves up and down ... the equipment's purpose was to be an automatic liquid agitator with a dish sitting on top of the plate which moved up and down as the motor rotated. Control the speed of the motor and you can control the level of agitation. The downside of this system was the load which is placed on the motor bearings, they need to be very good otherwise they will quickly fail with all this strange movement of the motor shaft.
So let's get down to "Brass tacks" and I will describe this piece of hardware to you.
MANUFACTURER UNKNOWN - Metal Weight For Motor Shafts
No idea where this metal hardware was fabricated but the equipment was of European origin
Material: Solid Brass
Round, solid Brass body measures 39mm length x 9.75mm OD
One end has a 9.5mm long grub screw (hex head)
Drilled into the side of the Brass, near this grub screw (6mm from the grub screw), is a small hole for the motor shaft approximate 1.5mm ID (hard to measure with the micrometer as it is so small)
I guess this hole (non-threaded) could be drilled out larger if need be.
That's it! Because of the point where the motor shaft is attached to the weight, as the shaft rotates, the forces will vary wildly - totally unbalanced, the result is that the motor shakes like crazy and anything the motor is attached to.
Weight is 24g
COSMETIC CONDITION:
USED
Clean (and shiny, I like Brass to look like Brass!)
NO damage at all to the grub screw, thread or the Brass hardware.
I have now packed this Brass weight into a sealed clear plastic pack to reduce the effects of oxidisation on the Brass and it now waits for a "lateral thinker" to find a use for it! Shake Baby Shake!
