my brother works in a medal working shop he got me a piece of 1/4 scrap
aluminum 8' long by 4"wide. he said it was cut off and would be trash
anyway.

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...
