winding your own coils

Can anyone point me in the right direction to find information on winding your own coils for cross-overs. I've got a table for DIY coils but it's limited and wire sizes are AWG. I'm living in Southern Africa and everything is in millimeters. I find easier to wind my own as living in the African bush there are no Parts Express in the village. I've been told that the CALSOD programme has a down loadable section for making your own coils, but I can't find a web site for it that is open. Any help would be greatly appreciated. thanks:confused:
