    oil in frame norvin

    our oil in frame vincent frame is finally finished. usually we would drop the engine slightly more than we have here. but that means that the engine oil drain plug has to be moved, it just entails drilling a tapping a 1/4" hole underneath the engine but this customer wanted to retain the standard drain plug. on the left side of the engine.
    plus we only fitted a head steady on the front pot, as there have been some concerns concerning expansion of the engine.

    so what's the theory with oil-in-frame? doesn't the frame get hot as hell? welding slag in the oil? I don't know anything about it, just curious.

    very awesome.

    Very pretty brazing, draken.

    About the drain plug, why not build an access hole right in the frame tube? The access hole could be a piece of frame tubing turned 90 degrees and brazed in, something like this: ==O==

    It could be reinforced all around, and it could have a removable cover built into it.

    I guess that idea wouldn't work if the oil is going to go in that part of the frame.

    bronze welding requires very tight tolerances at the joints, it's only a form of golden coloured glue to simplify it. we purge the frame, from different directions, t45 is a very pure steel. and you can see that there is a bsa type filter in the frame, behind the engine but pointing towards it. different sized holes are drilled to ensure the oil flows the way you want it to. yes the frame gets warm, but it's what the customer wanted,
    the drain plug issue was to do with the engine not the frame, they wanted to retain the original, which meant we had to raise the engine slightly.
    the other problem with putting a vinny in a ready built wideline is the front exhaust pipe to frame down tube clearance. but as we build these frames that was taken care of at the begining.

    this link is not a brit bike, but a frame and rear suspension set up we made to take a 145 bhp aprillia motor.

    Wow....that's going to be something!
    Great spirits have always found violent opposition from mediocrities. The latter cannot understand it when a man does not thoughtlessly submit to hereditary prejudices, but honestly and courageously uses his intelligence and fulfills the duty to express the results of his thought in clear form.
