I guess they got replaced by the band saw.

...though building a bandsaw (or modifying the
one you have to cut steel - mostly a speed issue and the correct blades)

Still looking for a 'worm transmission' after all these years.

...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.)

Heh!

Thanks!
