    The brake line being tubular would I expect have a lower mass/inertia than solid rod of the same diameter and hence put less load on the cutting blade.

    With high osscilation this would be quite a substantial difference.

    As for getting some brake line, just go to the wreckers. Repco will charge you the earth for the stuff.

    The worst that can happen is you will fail.
    But at least you tried.

    Essentially this is a hand powered scroll saw for very light materials. Had I worked out the design to make one myself I would have used massively stronger materials. Maybe welded 25mm SHS in 1.6mm wall. I don't think the inertia will amount to much at my hand speeds.

    If this uses standard brake line then I would go to the wreckers as Rob suggested and as to bending it, do it like I have always done it in the past. Bend it in your hands. Brake line will not kink unless handled very rough. I do wonder tho if this uses bigger diam than normal. I think it may even be fuel line looking at the picture. With care this can be bent by hand too. I subscibe to the KISS principal.

    Here's a link to a video by a maker of one of these Marquetry Intro (HD) - YouTube , and more on his version Marquetry Saw - by Woodenwizard @ LumberJocks.com ~ woodworking community .

    I think there are advantages to making it as light as possible - as it fills a niche which is about cutting very small pieces of veneer.
