      Model Scale: 1/8 Rating:  (2 votes - 5.00 average) Thanks: 0

      Hy boys..............just for the fun of it, and to take a rest of my motorcycle building for my client, I decided to scratchbuild a 1/12 scale lathe, based loosely on a vintage American lathe from 1890....I just love machines, and the older the better!

      I thought to begin that, if I could succesfully make a scale faceplate for the lathe, with "T slots" and everything, I would be on my way.....

      Take a look....

      My hand gives the scale of it....

      Most of the model will be done in acrilic plate and styrene Mini-micro lathe , using many bevels and putty Mini-micro lathe fillets to give the impression (Once painted) of cast parts....

      By the way, this little beast will be a fully working model....


      To be continued.....

      Mario

    Now this is a project I can't wait to see. Great start Mario.

    I now realize I should have been more specific.

    As an example of the "cast" parts, let me show the lathe's feet(They support the bed) and the tailstock body....

    The feet were made in 2.7 mm thick acrilic plate and styrene Mini-micro lathe sheet, the tailstock body was made in 5 mm thick acrilic plate and the barrel in turned and reamed aluminum...

    Tomorrow I'll show the tailstock working, for that matter, I'll have to do some seriously precise turning and use a left hand tap and die....

    See ya.............

    Beautiful work Mario.

    Are you ever going to revisit the Rolls K72 chain you started about 14 months ago?

    Thanks Tage!!

    A propos the Rolls, I bought the Star of India one, so I'll be building those 2 Rolls in parallel in the near future....:)'

    The tailstock parts..............

    First pic:

    Upper line from left to right: Body locking nuts and washers, 1 mm grubscrew for the retaining collar, spindle guide and locking lever, center.

    Middle line: Body bed locking plate with 2 mm threaded studs, spindle with 1 mm wide guide milled in the spindle body. (The spindle is threaded internaly 3 mm left hand thread in the back and drilled and reamed 2 mm in the front to receive the centers)

    Bottom line: Spindle mainscrew threaded 3 mm left hand on the left and 2 mm right hand on the right to receive the hand wheel, locking retaining collar, handwheel and handwheel locking nut.


    Following pics, the tailstock body in which you can see the bed guideways and the assymetrical design.....with the first primer Mini-micro lathe coat, you can see the "cast" look I want to reproduce...


    Mighty small all these.......

    hello,

    I wished I would have a lathe in original and you are founded sometimes thus to fun a model such, this is crazy.

    Been working on the headstock and the lathe's bed....

    The bed was made from acrilic plate of different thicknesses exception made for the bed guideways which are of K&S Mini-micro lathe rectangular brass...

    The headstock is also from acrilic plate, styrene Mini-micro lathe and goes installed in the bed the same way the tailstock does...

    The spindle is made from hardened steel bar taken from discarded PC CD players and it runs in ball bearings taken from discarded PC cooling fans....these bearings measure 8 mm outside dia., 3 mm inside dia. and 4 mm thick....


    The last pic shows the spindle's nose, turned from a 5 mm Allen bolt which was rectified on the spindle itself to insure maximum concentricity....

    There will be more............

    Mario

    When this is done Mario, will you be using it to build a 1:43 scale model?

    yikes. I'll stick to 1:8 thank you very much. My fat fingers can't handle anything much smaller than that.

    Oh, now this is one of the best things I've seen all year. I'd love to see how it works and what you can make with it.

    Some new adventures with the micro lathe.......the longitudinal carriage with some interesting and necessarily precise milling operations......





    [/IMG]


    [/IMG]


    [/IMG]


    [/IMG]


    [/IMG]


    The carriage on the bed......the millings were made very close to tolerances, but the final approach was made by lapping the carriage in the bed with some Brasso polish.....very amusing and lots of elbow grease....

    The carriage now slides swiftly, with no apparent side play......


    [/IMG]


    [/IMG]


    [/IMG]


    I am using a 12 Volt DC electric motor with great torque, but a scale casing was produced to imitate the original in the prototype....

    [/IMG]


    [/IMG]


    [/IMG]


    The motor inside the casing.................


    [/IMG]


    [/IMG]

    I tested the motor inside the casing for several minutes and had no temperature problems....thats a relief........................

    Next time, the tranmission pulleys and counter shaft.....can t wait to test it running.....

    Cheers
