Shop Press

[EdK]

Willie warned me about the arbor plates being junk cast steel of unknown pedigree. The ones that came with my shop press look like they are cut from flat steel and not cast. Is there a good way of determining if this is true or not? I was thinking of drilling a hole in one and observing the chips to see if they curl or are more of a powder, like cast iron. Any thoughts?

Thanks,
Ed
