   Yes, I do that by making a change to gpg.conf file, each time I need
to sign another key... well, GPGShell does it for me (I can chose
between 2 saved config files), let me check what would be the line to
add to gpg.conf file. Please note probably it is possible to do this
without changing the gpg.conf file, by using gpg from CMD prompt instead
of using a GUI, but I am not sure how to do that... The line it adds to
the config file is:

secret-keyring p:\gpgfolder\secring.gpg
no-default-keyring

where p is the letter assigned to the pendrive, and gpgfolder is the
folder where your secret ring is. I am not sure why I need the
no-default-keyring line, but I tried without that line and things didn't
work so fine...

  Best Regards

P.S: if you are going to carry your whole private key in a pendrive,
make very sure it is protected with a good passphrase...
