    Default Hippie Hippie Shake Wäinö Chopper. Kawa Vulcan 800cc.

    Moro.

    I had a hard hippie chopper fever and the only "real cure" for it is to build such a chopper.
    I bought a suitable Kawa Vulcan (Wäinö) 800cc -96 for it, quite cheap.
    Kawa was cafe racer style build and really awful to drive.

    After disassembling the unnecessary parts, it was ready to change shape.

    At Solidworks, I modeled a girder fork to its current frame change. The trail seems to be ok.
    Need to buy material. A pipe with a wall thickness 3-5mm is probably ok because otherwise the fork will become too heavy when the material is, for example 22mm iron shaft.

    I designed a pic of my possible coming Chopper.
    In the summer you can see what the end result looks like
    So, next i have to move on to the practical work because there is still a lot of work to be done.

    cool looking upswept pipes on your mock up. when I made mine, I went to my local bike shop and dug through a bin of takeoff exhaust pipes. I was able to find the angles I wanted out of some old harley headers. welded em to my own headers and cocktails. I left them natural and hot blueClick image for larger version.

    I finally got the prototype girder fork ready.
    I think it seems quite reasonable. The fork material will be 22x5 E355+C tubes.

    Nice aluminum build fixture. Light, won't rust and spatter won't stick to it.

    I made a 3mm walled hydraulic tube (22mm) model version of the girder fork.
    The final version will be made of a stronger tube E355 22x5.

    Hippie jae jee!
    Now i started wank...grinding pipes
    Before welding the girder fork, the parts must be polished like a chrome surface.
    In this way, you will save time on the final grinding before chromium plating and the chromium surface after chromium plating will be really good.
    In the second picture on the right side you can see the pipe before grinding.
    This is where it progresses.............

    I have a Vulcan 1500 and I think the 800 is literally the same size, only bored smaller on the inside. It's also much lighter obviously. Does anyone know how it works? I met a guy with an 800 and the engine looked the same size.

    While the girder fork plate parts are completed by laser cutting it is time to think about how to implement a foot clutch and manual transmission. The foot clutch is made of a combination of a gear pedal and a clutch cable. The second picture has a vision of the upcoming manual transmission but let’s see what the final version is, time will shows.

    Weeeell.
    The footclutch is finally ready.
    I did such parts by turning and milling. At the same time I tested the clutch and it worked great.
