  • Posted in thread: Self Setting Parallels for the Drilling Vice on 01-23-2017 at 04:05 PM
    What I use to keep the parallels against the jaws is a piece of steel banding bent in half. It
    has sufficient spring for the job and if necessary can be opened out again afterwards.The
    banding is abou...

    With the brackets ready to fit, the first one was pushed in place. Using the DRO's PCD
    function, it was easy to set out the 6 holes for the retaining studs. Tapping holes went
    through both parts and t...

    Here are some diagrams of buzz coil circuits. The first 2 attachments are the same, but
    displayed differently. Put whichever one you want to try in a wooden box that looks like the
    original with finge...

    Now after that little light relief, it was back to the next real job: the crankshaft brackets.
    They have a taper along their length so to hold them in the chuck, the thin end was padded out

    Moving on down we come to the push rod bracket. This required a piece of 5 x 5 mm steel, of
    which I had none. A raid of the potentially useful bits yielded something that didn't take too
    much effort t...

    The model uses glow plug ignition but the glow plug is rather out of scale. What I did was to
    machine the hex of the plug down by 15 thou. on each face. The round part below the hex was
    also reduced i...

    After the bore was done, the first crankshaft bracket face was machined using the boring head
    as a fly cutter. Not a lot of room between the mounting lugs on the back swing with the tool
    wound out!864...

    There is a protuberance on the bottom of the casting that I suppose is there as a chucking
    piece, but for what purpose, I cannot think. So, the first enhancement was the fitting of a
    (dummy) crankcase...
