The old equipment used in hat factories like crown irons and pouncing machines would clamp on to the center boss inside the cavity. These machines are hard to come by and expensive now but many of the high-end hat makers still use them.Hat block question…
I understand the purpose of the center hole on the underside of a hat block. However, I don’t understand the purpose for the deep circular trough.
Is it to make the block lighter? Maker it easier hold onto? Is there equipment that needs to be attached to the underside that needs the resess?
Thanks,
