Step 5: Cutting the Steps.

Once we have our big and strong plywood ready, we start to make a carton stencil of the shape to make sure that we have exactly the same shape in all of the steps.

Then we draw it over the board... but we make two stencils one for the right and one for the left... so we can alternate them and minimize the waste of material by puting one "inside" of the other.

We use a jig saw to make the cuts... dont forget to calibrate the angle of the blade and be patient 'cause some times the blade make a non desirable angled cut insted of a clean 90 degrees angle. Take it easy and practice... you can also draw the steps whit a 3/8" space between one and the next...this gonna be very usefull in case you need to rectify some cuts. (So dont be afraid to make a mistake...we can always find a solution)
<p>Do you think the premise of these stairs could be build to be used as an unfolding attic stairway? I've got to get a safer way up to that area after falling off a ladder. And a standard pull down ladder isn't the way I want to go. I'd like to be able to descend from the attic forward facing and I don't really have the space to do much more than this anyway. Anyone ever build an attic pulldown stairway?</p>
I&acute;m pretty sure it may work... maybe you can take the mechanical parts of a regular pull down ladder and adapt this design... I think the problem will be about the space you need... the size may be as much as the double compared to a regular pull down ladder... so you have to make sure the hole in the roof must have the right space.<br>Instead of having steps of 4 inches...like in a regular pull down ladder... you need at least 8 inches for this design to work safely.<br><br>Hope you try it!
Can't it be dangerous? especially when sleepy?
I guess maybe... but you get use to really fast...<br>we use it all the time... and even kids use it...<br>
I must say that it's an example of good designing.
This was made by the Brazilian inventor Santos Dumont, in the early 1900s.<br>http://www.youtube.com/watch?v=9ai2v2xzDgc&amp;NR=1

I love it! I just built something like it. Look for &quot;Single Step Stairs&quot; but it is only four steps. Great job.
thank you!!!
Good work. FYI- They are called Alternating Tread Stairs.
It&acute;s a great solution... need some work... but its very effective!! good luck!
these will work well in my new shop to save floor space :)
