    This is explained corect by Peter.
    The flat that I use is first checked on a granite measuring block as you can see on the previous picture 's.
    Here is the latest series of photographs of the scraping.
    As you can see the final scraping is for the oil .
    I've scraped the sides of the Y axis but I forgot to take photographs.
    I wish the best for the new year to everyone that you have a creative year.
    Kind regards ,
    Andre

    Since everybody likes photos,here some pictures of the changes to the knee.
    Important is a good arrangement of the workpiece and a proper alignment so the error margin is as small as possible.
    It is important that you make a plan off attack .
    A strategy of how to start your project which consists at first of making a list that says what all needs to be adjusted and which alterations you want.

    In this case I want some adjustments related to central lubrication system because original grease was used instead of oil to lubricate so therefore
    it is necessary to drill new channels.
    Also to support the Y ballscrew it is necessary to make an opening where a custom bearinghousing can be mounted.
    Also a balancing weight is needed to support the weight of the knee to compensate otherwise I think the servo motor will not long survive the abuse.

    The last week was one of heavy lifting the maneuvering of the heavy component was not always easy if you are working alone two hands are not always enough
    and you must improvise.
    The next thing I do is start going to make the smaller components.
    Do You want pictures of the parts alone, or also the making of the parts themselves ?
    Kind regards ,
    Andre

    Hello everyone,
    Today I started machining the first part of three which the servo motor of the Z axis will hold.
    The first part is the base plate which directly on the knee is assembled.
    I prepared the pocket to fit the base plate previously.
    containing 6 M8 holes and two 8H7 holes for clevis pins to keep everything in place.
    I used a piece of aluminum quality 1.6082 T6 ( T6 is the treatment the aluminum received) so it is good for milling.
    First I put my vise on the table and aligned it properly .
    Than i machined it in the proper order in this case first the bigger side
    than I turned it around and put a cylindrical piece between the part and the vise so it will be square and did one small side.
    Then I did the facemilling on the second small face also with the cylindrical piece.
    and after that the second bigger plane and OK.
    After that i took an endmill and did the milling off one side .

    I want the edges to be round so i am going to mill some rounds on the corners.
    The first thing i will do is make two small center drill holes on the positions off the center off the radius.
    But first i have to choose a workpiece zero point.
    There are several ways to find an edge you can use a piece of paper ,a cylindrical piece off metal which is painted with a color marker ,, or a wiggler center finder is a tool used in the spindle of a machine such as a mill. The device is used to accurately determine edges or markings and therefore the center of a workpiece or a previously machined feature during the set-up phase of a machining operation.There are also several 3d edge finders mechanical and elektronic.Here are a few .

    Now I will locate the center off my milling table and make it zero X and Y on the DRO because I can use my table as a rotary table (so if you have a rotary table the result is the same) if it is done I put my workpiece on top of it and use pointed pin to find the previous drilled center holes.
    If done so see that the vise is fixed .
    I use a roughmill first and later an enmill for finish the rounds.

    After the rounds I rough out the slab and finished whit an end mill later I made two chamfers by rotating the table 45 degrees.
    After that I drilled the holes and OK
    Thats all for today.

    Hi Andre
    great pictures,i greatly admire the job you are doing to your mill:clap:
    you must have put in a lot of man hours!!
    just a quick question when scraping the slides how did you get both sides to match as you would not have been able to sit your straight edge directly onto them because of the dove tail?
    might seem like a silly question but i was just curious as i am no enginner
    Tom

    Hello Tom,
    first of all there are no stupid questions.
    We started with the support for the table .
    As you can see on the pictures first I have the upper surface with a facemill straightened and next the dove tail .
    I started scraping this section and than after the milling on the table I checked how far off straight she was on my granite measurement block (1,5m*1m)
    as you can see with a dialtester and after scraping and measuring I used the support it self to check for flatness until within the tolerance.
    Is that what you wanted to know?
    Kind regards ,
    Andre
