I am getting close to needing to build a ladder for my 10'+ tall book
shelves. I'm probably going to go the less expensive route and simply
build a lean-to ladder. Fancy hardware and wheels and bars and stand
offs would be at least $1,000.00.

Anyway has anyone done this? I am in particular wondering what the
minimum angle should be to prevent falling backwards. I am not going to
attach the ladder to the book cases, my plan is to put rubber feet on
the bottom and maybe felt pads where it will lean against the book case.
I'll just pick it up and move it as needed.

I am certain a normal step ladder ladder is probably a good angle but I
do not want to take up any more floor space than necessary if I leave it
out and leaning against the book case all of the time. Alternatively I
can stand the ladder at the end of the cabinets out of the way.

Leon, the thought just occurred to me that you could use unistrut,
with a pair of rollers but instead of using the rollers on a vertical
install, use them on a horizontal or sideways install.

And a couple trolley's.

You could make a silicone plastic slide to grip the underside of the
Unistrut effectively keeping the wheels in contact with the Unistrut.
and then bolt a ladder to the whole assembly. Then make a simple wheel
setup for the bottom of the ladder. with a little bit of work, and
painted to match or contrast your book cases it should cost total less
than 150, I'd think. And should last until the house fell down.
