First step, here is the instructions for mirroring.  I would suggest using rsync.

https://www.scientificlinux.org/download/mirroring/

For updates you really just need two directories.  The main RPM directory, and 
the updates/security directory.  So, for Scientific Linux 5.2 i386 you would 
need the following directories

rsync://rsync.scientificlinux.org/scientific/52/i386/SL/
rsync://rsync.scientificlinux.org/scientific/52/i386/updates/security/

And for our example, we'll say that you are mirroring them to

http://mymachine.com/scientific/52/i386/Main/
http://mymachine.com/scientific/52/i386/Updates/

We'll assume that mymachine.com is within your firewall, and that all the 
machines can get to it.
Now, on each machine you would need to edit the files /etc/yum.repos.d/sl.repo 
and /etc/yum.repos.d/sl-security.repo so they look like the following

# cat /etc/yum.repos.d/sl.repo
[sl-base]
name=SL 5 base
baseurl=http://mymachine.com/scientific/52/$basearch/Main
enabled=1
gpgcheck=0

# cat /etc/yum.repos.d/sl-security.repo
[sl-security]
name=SL 5 security updates
baseurl=http://mymachine.com/scientific/52/$basearch/Updates
enabled=1
gpgcheck=0

Hope this helps.
Troy
