I did that calc a long time ago, but I was too lazy to do it the hard way. I got something called "SPARANA.exe" to do that for me. It was pretty simple, but only runs on 16 bit machines, so you'd have to use it on XP or DOSBOX or something similar. Another good one is SparStrength.xls at http://www.acrodesigns.com/excel/SparStrength.xls . This makes it dirt simple also. Mark Langford ML at N56ML.com http://www.n56ml.com
