Yeah - that'll do it. Mine is like the one in the link Jim posted. Sheet
metal.

I seldom have to make long cuts in 1/4". When I do, it's with a
steel-cutting blade in a worm-drive circular saw:

VERY noisy, with orange-hot chips flying everywhere. Started a small fire
once.

You take off the handle on the bussines end and replace it with a steel
plate that has a linear bearing
mounted on the left and right sides. I used 1" DOM that i picked out of
the
scrap bin at my steel
supplier. Made 2 clamps, one clamp is placed on each end of the tubes.
...

So, the tubes are at least 8' long, or do you re-position for a cut that
long?


The tubes are 9' long. I haven't noticed any any saging
at that length, if they do sag it does not seem to effect
anything when cutting ( no noticable binding ). As i
recall the tubes have 1/4" wall thickness. I also have
shorter tubes for smaller work.
