Practicing without a drum...

This questions may seem silly, but I will throw it out there anyhow...
I have been practicing some of the Oro Seco with a few friends who have experience with the music. When we practice, I play the parts for okonkolo.
These have been my first experiences in playing bata, and I have enjoyed them. Unfortunately, when I go home - I do not have an onkonkolo to practice with?
I practice the rhythms on my congas, but the hand action is obviously different.
Any suggestions on what might be the best methods to practice without a onkonkolo?
