  • Office Chair

    I'm trying to remove a stubborn chair gas lift piston. I've tried everything - hammer, wrench, WD40, etc but nothing is budging it - not even one little jot. Any ideas before the whole things gets dumped ?

    I have had some good luck with chair disassembly by using a heat gun then freeze spray on the inside element and giving it a sharp strike immediately after the freeze spray. It helps to have everything supported by the outer element of the joint before you start with the temperature procedure.

    Kroil can also help. Apply and let it soak in for a while.

    Tip: If you do not have freeze spray, a can of compressed air will work. They are the same except for an internal tube or the lack thereof. For freeze spray the tube picks up the liquid at the bottom of the can while compressed air has no tube and picks up the gas at the top. If you invert either one, it instantly becomes the other. So you can use a can of compressed air as freeze spray if you hold it upside down.

    And if you look REAL close at an analog signal,
    You will find that it has discrete steps.
