On a Vaughn 4/5. The first block is a double drafting block. Top block is 21 inch diameter bottom block is 32" dia. How do I figure the reductions per block as well as the correct die sizes?

Thank You

good day Wire..

Check out the Forum "Ferrous", look for a question called "Calc info needed", there is a formula within that may help you.

Hello,

I actually found a patent titled " Wire Drawing Machine and Process of Threading the Same" which was assigned to the Vaughn Machinery Company in 1931 by the inventor, Edwin C. McIlvried. This patent specifically relates to the Vaughn double deck drawing machine and it shows cross sectional drawings.

Thought you might like to review it.
