I'm Hoping Somebody Can Help Me Out. I Have Three Blocks Of Old Yellow Micarta, That I Would Like To Have Turned Into Ferrules. 2 Of The Blocks Are 28mm X 28mm X 115mm. I Think Each Of Those Blocks Would Be 6 Or 7 Ferrules. The Other Block I Have Is Slightly Larger, But My Battery Died In My Micrometer Before I Could Measure It. That One May Yield 7 Or 8 Ferrules. Can One Of You Wonderful Cuemakers Help Me Out?
