Default Reliable, long straight edge

I bumped into a problem this weekend. I needed a straight fence of
above 2.3 metres in length to do some edge routing. I couldn't find
anything in my small and basic shop that I knew was TRULY straight
across this length. (found some particleboard scraps about 2 metres,
but as I sighted down the long edge, I could see some dents, as well
as a small curve in it.

What do you people use as a reference straight edge? (preferably
something that stays straight for a while...iron, aluminium?)

thanks for your advice...

Usually, wood, but it tends to require some preparation as most commercial
boards aren't straight enough.

Failing that, iron or aluminum is useful. Aluminum is more easily dented, but
is easier to handle. Some say angle iron (or aluminum), but I tend to prefer
bar stock, as there's less likelihood of the angle piece interfering with
whatever you're trying to do (by catching on a low handle or a cord).

Do a google search on "cutting guides". A cursory look shows most of them seem
to run about $50 or so. I've been using an aluminum extruded guide for about 25
years that I paid considerably less for. I just clamp it to the panel and run
the circular saw (or router) against it.

How straight do you need - what deviation ("tolerance")
from mathemical straightness would affect your project?

Hi Marton,
I use a 1" square piece of aluminium tubing. Normally works great but
as Charlie says, even at 1" it can interfere with certain cuts. Cheers,
JG

aluminum 8' long by 4"wide. he said it was cut off and would be trash
anyway.

A sheet of carefully selected MDF is gonna be
VERY straight. 1/2" or 3/4"... Rip a piece to the
size you wish making note of factory edge.

You "might" find a metal stud that is quite straight
also. These are a little harder to come by but can
be bought in most buidling centers.

"Marton Czebe" I bumped into a problem this weekend. I needed a straight
fence of
above 2.3 metres in length to do some edge routing.

snip

My preference is a 2" x 2" x 1/8" x 96" long aluminum angle which translates
arrroximately as follows:

50mm x 50mm x 3mm x 2.44 m.

Add a couple of C-Clamps and you are in business.

If you go this route, I'd recommend the heavier gauge metal--it won't
flex in the middle.

I do the same, but my chunk of aluminum is a channel. It's not
straight in the checking jointer tables for co-planar sense, but it
makes a great tool guide.

Here is another time-tested solution:
http://www.womeninwoodworking.com/ti...ingpoints7.cfm
I have two I made from 1x3" auuminum box glued to 1/4" hardboard. One
other mod - leave an inch or two of hardboard on the "back" side for
clamping, so your clamps don't interfere with the saw or router.
Better yet, leave enough hardboard on each side so you can use one
side for your saw and one for your most common router setup. Trim the
guide with the tool you will be using it with, and the edge can be
used to set the position to your marks.
