Here is the other half of the equation.
I took a piece of 1-1/2" black iron pipe welded a steel plate to one end.
Then I took a 9/16" lag bolt and cut off the shank section, rifle drilled it and welded it to the steel plate.
I bought some 15/64" hardened drill rod, cut a short piece for busting them loose, then a longer piece to push it out.
I drilled and tapped two holes for set screws.
One holds the drill rod in, the other secures the pipe to the ram of the press.
