You can do very sensitive detection of waves and ripples in cast iron table
tops with very low angle light. The benefit is you can see the full plane at
once versus just a line through it. Set up a bright light as far away as
practical in a dark room (slide projector works great). Adjust the height
until it just skims the table top.

I've been wanting a quality straightedge. So when I read this post, I went
immediately over to E-bay and ran the bid up $20, unsuccessfully.

Wow $1 an inch????
Has anyone had a straight edge made at a machine shop? I assume they can
make them straight but how much would it cost?

And when I looked at it the bid was up to $99. Of course,
since the street price on this puppy seems to be about 300$ or so,
that is still a pretty good price. If one needs a 6' long,
REALLY accurate straight edge.

I like Starrett rules at least as much as anyone but would like
to suggest that the kind of precision we expect of Starrett is
rarely needed in most woodshops.
Some time back I set aside 4' and 8' lengths of 1/8" x 1-1/2" x
1-1/2" extruded aluminum angle and 1/8" x 1-1/2" flat bar stock.
The flat is 0.125" thick and 1.500" wide everywhere I've measured
and, using the three-bar test, appeared straight over its entire
length.
The angle is similarly uniform in straightness, width and
thickness; but the outer faces do not meet at exactly 90º. Since
I don't use it for checking squareness, I don't care (I /do/ have
a nice Starrett square for that job) - I use the angle only as a
straightedge when the bar would not be supported for its entire
length (the angle is less inclined to sag when not completely
supported) and I always use the shortest edge the job requires.
It's been long enough since I bought the aluminum that I've
forgotten the exact price - but I think all four pieces cost less
than US$25. I drilled a 3/8" hole at the end of each piece so
they could be hung on the wall out of harm's way - and I got
crazy one day and hand polished the short flat straightedge
(using Gunk and a paper towel) until it was mirror bright.
No, they're not *ultra* precise - and they don't have scales; but
they do fill /my/ needs for straight reference edges as well as
would Starrett's best.
If the eBay price moves out of reach, you might find my approach
to be a adequate/satisfactory alternative.

Uh huh. And how long would this process take for a novice?

Oh man.... as a hobbyist I don't think I need anything that
straight.....(leave it alone ;-))
I'll check at the machine shop and see what they can do for me.

Of course, that Starrett 72in straight edge NEW cost over $300

Making them straight and having them stay straight aren't exactly the
same thing. The choice of the metal and the treatment of the metal can
require some expertise if one wants real precision which will last.

A few hours. I made 3 48" straightedges. See the description of my
experience.

My guess is that you can add another zero to that bid and you *might* win.

at a local junkyard I found some 6" x 1/4" hardened aluminum stock
that is as straight as I can measure.... for $1 a pound....
I just looked it up at W W Graingers, and it lists for around $415.00
It's currently going on eBay for $99

many many hours.
but seriously folks, for the accuracy that we as woodworkers need a
6foot length of 6" x 1/4" 6065t6 aluminum from a metal supply yard
will work fine.

depends how straight you need it to be. starrett stuff is not
overpriced for what it is. grinding a 6ft straight edge takes a huge
machine. I don't know if there even is one in my town
