Now, I wonder how to make a large jigsaw that uses regular
hack saw blades to do many of the things that the Blade-
Runner is shown doing, without tearing up a blade guide
in the process.

Look up walking beam saw - though building a bandsaw (or modifying the
one you have to cut steel - mostly a speed issue and the correct blades)
might be as easy, and would cut faster (but it's harder to pierce with.)
If you don't need maximum throat depth, bandsaws get much easier, as you
can bolt two wheels to a post, rather than trying to build a rigid C
frame (much like a jumbo shrimp or military intelligence.)
