Bill, you're scaring me here - you put ANGLE IRON through a table saw
- you're pulling
our legs eh? Maybe you changed the blade to 100 TPI or something -
tell me you didn't
hack away at a piece of angle iron with a 10 TPI wood blade - have
you counted your fingers
recently - perhaps pain isn't an issue for you :-)))

This sounds more in my line of thinking. Unfortunately, we don't have
Sears "over here" -
we do have LOT's places that sell beautifully made Chinese cr.. tools
instead though :-)

OK so far ...

Haven't tried this, but I get your drift.

OK

You'll have to expand on this for me - you rip an angle iron edge to
45 deg
then dress it with the conical sander - and then use a "slide
dresser" - I'm guessing a slide
dresser is like an automated stone dresser for carborundum wheels ?

This I wish !

My current thinking is to use a pair of 2.5 metre 20mm diameter
supported ways I have and use them
to make a slide mount for a grinder with an adjustable Z. The angle
iron needs to be accurately mounted below this.
The grinder is then dropped down in increments until the final pass
cut is made. The angle is swopped over to do the
opposing V edge (the Vee is actually an inverted Vee BTW :-) Problems
with wear in the stone will be an issue
no doubt. Obviously, this could all be automated, but when you only
want half a dozen or so then it becomes a little
pointless. I can imagine passing the grinder back and forth could be
quite therapeutic :-)
Maybe I WILL automate it and flood the world market for V edged angle
iron :-)


Back to you Bill for more on your method...

Cheers

Neil
