BACKGROUND:
You may be thinking "What The ...?" about this item ... to many these brass bushes would be considered as just used lumps of metal but I am "really big" on reusing or repurposing old electronic components and hardware, particularly from the point of view of sustainability.
Sustainability far more than NOT burying waste material back into the earth but consciously recognising the energy expended to create the item through it's various "stages" in life, beginning with the raw materials being extracted from the earth, processed, finished and then fitted into equipment - every single step used energy which is referred to as embodied energy.
To give an approximate representation of how much energy was used in the WHOLE production process of an item, I have created what I refer to as the Ee (Embodied Energy) value, measured in Mj
The Ee value is an approximation only and usually measured in Mj.
Coming up with an Ee value is an attempt to take into account the energy used for extracting and processing of the raw materials, manufacturing of the component, distribution of the component(s) and final assembly of the component. In fact the measurement of Ee can become extremely complicated and technical, many tertiary institutions are involved in this specialised field of science.
I have used various reliable sources online to arrive at approximate Ee values, these are approximations and the sole purpose is to raise awareness of the extraordinary energy consumed in the creation of various electronic components and hardware - it may give you cause to think twice before wasting all that energy and burying it in the ground, with the possible side-effects of poisoning the environment due to leeching.
HERE is a page I have created which gives some tables and more detailed information about specific Ee values for different materials plus a link which you can use as a starting point to investigate Ee for yourself.
These bushes were extracted from a reel to reel tape machine yonks ago but my problem is, which one? I used to work with four main makes of machines ... Tascam, Otari, Revox and Studer. Back in those days (80's ~ 90's) I would keep any salvaged parts in drawers or special lidded boxes AND MARK where the items came from ... the box I opened recently had no indications of which machine the parts came from although I have my suspicions - I "think" it was an OTARI but looking through the parts manuals (a slow, long laborious task) I couldn't see this part so maybe it was one of the other machines.
In any case, someone may find another use for this lump of metal which is totally unrelated to R2R machines ... better than throwing them in the garbage!
Try to think "outside the box" with these ...
