    Hi to all.

    After searching the Web for long time with no success I decided to post here.

    My interest is focused on the electronics side of some tests to be carried out on a free pendulum which I need built by a machinist. I lack the tools (and the dexterity for that!).

    Some refined construction would be excellent but not to the point of making this a costly attempt.

    Having elected an edge knife suspension, is it anyone kind enough to give the details of shape / sizes / angles of the V groove and the knife? My pendulum is planned to be about 1 m long with a weight, all in all, between 1 and 4 Kg.

    Of course a suggestion on appropriate materials for the suspension (trying to avoid spending too much $$$) would be nice as well.

    I expect the test to last one year at maximum.

    I would appreciate concrete data, if at all possible, supported by a simple sketch.

    Gracias for the time you will spend reading this. (No pun intended)

    I was aware of that thread.

    Any chances that I could get a simple sketch with dimensions?

    What is articulated and how, is a mystery for me. Keep in mind that I know nothing of all this.

    Gracias for replying.
