Hi Bill,

I am formerly from South Africa, so understand some of the issues around 
creating base technology for use in
developing countries.

Have you thought of using the stainless steel drum from a scrap washing 
machine lined with a muslin bag as a centifuge?

I presume you have access to a welding machine or can find a local handiman 
to help out.

You could use an old bicycle to provide the motive power and high rotational 
speed for the centifuge.  I will send some sketches later today if you would 
contact me direct off list.  I will send them as PDF's to reduce the size as 
your connection is likely to be a little slow.

Regards,
             Robin
