Making tracks with Al shapes & basic power tools

[Finster]

Here's a very detailed video of a guy who scratch built his own tracks from Al shapes using some basic power tools. I thought it might be useful for someone looking to build tracks for their project. If not directly usable perhaps it might at least stimulate some ideas.

Also in a previous videos the same Gentlemen builds a furnace, foam wire cutter, then cuts foam and casts the sprockets in Al via the lost foam method.

Hope this helps...
