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.

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.
