    Here we are again,
    Last week has been busy and have not don as much as I wanted.
    But now I've made the design for the Z axis bearing configuration.
    As you can see on the drawing .
    So tomorrow I can start the making of the parts.:dance:

    How are you going to limit backlash in the bevel gears or is this just an adjustment drive?

    Hello Peter,
    On one side there will be the timing pulley and the other side is the ballscrew.
    The bevel gears I have are helical bevel gears (the original BEAVER) and I will adjust them with spacers so that slack will be no more.
    Kind regards .

    Hello everyone,
    Here are a series of pictures of how a component from the Z axis is machined.
    This part is made of steel and it is one of the more complex parts I need.
    The series pics are self explanatory.
    And in the right order.

    Tip drawing the outline on the workpiece itself so you can see what ultimately the part will be.
    Also as much material will be removed make sure that there is material left
    to machine after the biggest piece is removed because the workpiece will deform by tensions in the material.
