1X1 Conical Spinner and Backplate

 A friend of mine needed a very large spinner: a 1X1 ratio of 4" diameter/ length, This is the 2nd run, as the first was wayy to thin, and wobbly. What I did was increase the thickness of the backplate, added a washer 'cutaway' and increased the final dimensioned center hole for minimal reaming to final needs ( .005" shrinkage)
