Hi Gene - have a read of the following. http://www.google.com/patents?id=pWQeAAAAEBAJ&printsec=abstract&zoom=4&dq=5295411#PPP1,M1 The math for the "rattler" design criteria is on there too. I made one for the Z axis on my router, which suffered from resonance problems. It cured it completely, but it is noisy - only until the HS spindle starts cutting though :) There was little thought to the design other than what fitted in the diameter available with what material I had lying around, nevertheless it works. Mine is 62mm dia, 20mm thick in Al. It has four 17mm "rattler" holes bored on a 36mm PCD with 15mm ground steel slugs for rattles. It's bored 10mm to fit stepper shaft and held in place on shaft with two 4mm setscrews at 90 degrees to each other. Top and bottom covers are 2mm thick Al held in place with 8 - 3mm CS screws.
