How to add binding space to memoir twoside

I'm using the LED template to MSc which uses memoir twoside. I need to print it and it requires extra margins for binding.

How do I simply add the extra space on the spine side of the page?

\documentclass[11pt, a4paper, twoside, makeidx]{memoir}
\input{style.tex}

STYLE.TEX:

\usepackage{graphicx}
\usepackage{epsfig}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{amsthm}
\usepackage{booktabs}
\usepackage{stmaryrd}
\usepackage{url}
\usepackage{longtable}
\usepackage[figuresright]{rotating}
\usepackage{geometry}

\usepackage{polski}
\usepackage[cp1250]{inputenc}

% *************** Wygląd strony ***************
\settypeblocksize{*}{32pc}{1.618}

\setlrmargins{*}{1.47in}{*}
\setulmargins{*}{*}{1.3}

\def\baselinestretch{1.1}

\checkandfixthelayout

% *************** Stylu rozdziałów i podrozdziałów ***************
\makechapterstyle{mychapterstyle}{%

\renewcommand{\printchaptertitle}[1]{%

}%
\renewcommand{\printchapternum}{%
\chapnumfont\thechapter%
}%
}

\chapterstyle{mychapterstyle}

Are line/page breaks allowed to change, or is this a "last-minute" correction that shouldn't affect (most of) the layout? –  lockstep Jan 26 '13 at 13:30
Sadly "Last minute". Currently looks great... on screen. –  Holy Sync Jan 26 '13 at 14:07
It's necessary to see the part of the preamble where the page parameters are set. –  egreg Jan 26 '13 at 14:25
Question updated :) –  Holy Sync Jan 26 '13 at 15:15
OK, It seems I found the solution: (at least it worked for me) \setlrmargins{}{2cm}{} –  Holy Sync Jan 27 '13 at 12:21

As described in the memoir manual, chapter 2, the command \setlrmargins is available to adjust margins, with arguments:

\setlrmargins{<spine>}{<edge>}{<ratio>}


Only one argument could be given, with * for the two others e.g.

\setlrmargins{*}{2cm}{*}


There is also a command

\setbinding{<length>}


that adds to the inner margin to allow for the binding. This should be added after setting the page size, but before setting the margins.
