    Default New Project "Immortality"

    The Egyptians believed in an afterlife. The Pharaos built massive edifices to house their mortal remains, furnished by everything they may need in the new life. That is the inspiration for this automata project. A casket which will be 430mm high will have a carved lid of a king, with the casket under, which will contain a mummy. The lid will open, to reveal the mummy, and as the actuating handle is turned, an action takes place. I can't give away what that will be for two reasons, one the surprise element would be lost, and if I can't get the thing to do what I envisage, I will need to invent an excuse.....or a revised intention

    The drawing,

    Blank of the lid, made from Jellutong.

    The carving of the lid, and to fabricate the casket begins the project. Thanks for looking, hope it will be interesting to follow.

    Default WIP - Making The Drive Gears

    The main drive gears determine how well the scene moves, so they are important to the work for smoothness, speed and strength. The process is :

    First .jpg

    Paper templates are glued to the ply blanks.

    Second.jpg

    The bottom of each tooth is drilled, and teeth cut close to the lines on the scrollsaw, spokes are removed.

    Third.jpg

    Fourth.jpg

    Sanded to final diameter, and each tooth is sanded to the line of the template.

    Clear lacquered.jpg

    Sanded to 320 grit and clear lacquered. The four gears took 2.5 hours to complete.
    Thanks for looking,
    Gus

    Default WIP Prototype Mechanisms

    There will be three cams which contain the information to activate various parts of the scene. The blanks are cut in conjunction with the elements above to create the desired movement. The the way I do this is attach a cable to the part which it controls (or levers if that is what will do the job). Then to the arm below, which has a bearing to follow the cam edge, mark the cam at the points to create the desired movement. Usually this is a long trial and error procedure, marking, cutting, sanding, reinstall, test, remark, cut etc etc etc. Sometimes requiring a new cam altogether if I get it completely wrong. As each cam is completed, the next is cut, and rotated on the camshaft to time it with the previous.

    Blank Cams.jpg

    The three blanks

    The first one moves the lid to reveal the mummy inside. The video shows the revisions made to get it right

    Cam.mp4

    The cable is threaded to the lid of the casket and pulls it open. A spring closes it when the cable is released by the cam

    Internal.mp4

    The result is,

    Lid opening.mp4

    The other cams will be cut to move the mummy's parts, that is the next job.

    Apologies for the video quality, and thanks for looking,
    Gus

    Default WIP - Mummy's Mechanisms

    The two final cams operate the mummy's movements. Surprisingly quick to cut with few modification/revisions, ( a matter of luck) this finishes the mechanical aspects of the work. Time so far, to completion of the prototype is 57 hours, of which the carving was 22. Not counting the "middle of the night" awakenings which often solve a previous day's problem......
    The two videos attached show the three cams operating, and the levers they control.
    Next is the fabrication of the final revised, modified and actual mechanisms, preparation for painting and decoration of the piece and reassembly.
    Thanks for following the project so far,
    Gus
