The Secret Society of Lathe Trolls

Today I understood that the mechanical lever in direct type injectors is not used to extend the movement, but to reverse its direction (the injector must be open when voltage is applied, not when there is no voltage). In the senis of using injectors, I thought of them as the source of the piezo stac...

Unfortunately also don't know exactly how they work. I once found out about them by the way, when I was looking for jetting valves for jet printing solder paste. There are two varieties; the indirect one (with shorter piezo stack + chydraulic motion amplifier) ​​and the direct one with a longer piez...

Hi, Maybe it is possible to use a piezo stacks from automotive piezo injectors, or maybe just cutted/modified injectors as direct/lever drivers. Used one can cost 30 dollars

They are made of PTFE or some other sliding material. Due to the weight of the head, they slide along the rear edg...

The mysterious part is LM317 - adjustable positive voltage regulator.

Since the topic has been refreshed, one of my proposals is the Technics Sl-1700. It has the same engine and platter as the SL1200, but it is much cheaper, especially damaged ones. From this turntable we can pull out the motor itself (the arm will also be useful, it is also the same as in the SL1200)...
