one piece step notch

I have a bunch of 2"x2" metal that is 1/8  inch thick.I was wondering if that would be a good c-notch.What are the sizes of a one piece c notch.Thanks

i wouldnt advise usin 2x2,especially 1/8" wallthe smallest i would use,square tubing wise would be 2x3x3/16"

ok thanks ill just buy one thin or go see how much metal cost.I was told to cut all the corners at a 45 degree is that right.

I made my cuts for my notch at about 33 degrees or so.  The notches had about 60 degrees when all was said and done.  2x3 at 3/16" should be the minimum for your notch, just to be safe.

Draw it out on the floor(card board if your married and building it in the garage ) with a sharpie. This has worked great for me, until the wife saw all the sharpie drawings.

^^ It is usually a good idea to take a couple of minutes and draw it out 1:1 before you start cutting.  Sometimes the idea looks different on paper than it did in your head, drawing it out gives you the option to adjust/change things if you want.
