The angles I needed were the one for the dados and the bottom. Thanks
everyone for the input, I got it done.
Thanks, Darrell

The usual angle is out 1 ft at the base for every 4 feet of rise. Hope
that helps.

If you want maintain all the original angles and just change the
ladder length, use the following.
Original Bed Height = OH
Original Ladder Length = OL
New Bed Height = NH
New Ladder Length = NL
NL = OL * (NH / OH)
Hope this helps

Darrel,
If you know the height of the bed and the distance from vertical that the
ladder has to be, then my grade 10 math teacher will be really happy. You
can use the same formula that she taught me soooo many years ago. A*A +
B*B = C*C where A is the height of the bed and B is the distance from plumb
and C is the length of the ladder. If you want proof I have that too.... ;)
You can see it here, I used that just a couple of weeks ago to make new
ladders for my son's bunk bed.

up and down and no complaints or tumbles yet!
Hope this helps,
Howard

If you have ever been on a sailboat, you know they have a thing called a
companionway ladder.
Everyone is different.
Take a trip down to your local library and check out "Skenes, Elements of
Yacht Design".
The subject is discussed in detail along with how to solve the problem you
describe graphically.
BTW, the book is long out of print, so the library is your only good choice.

Thanks, this seems to work. Now all I have to do is figure out the angles to
cut.
Thanks, Darrell

It's for kids. It's not the wrungs that I'm worried
about. It's the total length.
Thanks, Darrell

Are the beds for little kids, big kids or adults? The distance between
wrungs will vary depending on the intended occupants of the beds.

Looks like they've reprinted it - http://tinyurl.com/yv8np
Someone said it's the 6th edition (as opposed to the most current 8th)
that is the reprint though. Not sure if it makes a difference or not.

I would say the simplest way would be to use the concept of a similar
triangle. Use the ratio of the height of the actual bed to the height in
the plans as the multiplier of the length of the ladder.
