The time available for the glue/cement to dry/cure/set is limited on 
production machinery (since say 1880) only by the number of removable 
caul sets or clamps available to the hammer maker.  A set of hammers 
does not need to occupy the press any longer than it takes to apply 
the pressure, lock the clamp and remove it.  When Dolge wrote, "it is 
estimated that two expert gluers can cover about two hundred and 
forty sets of hammers in ten hours on one machine".  Those were the 
days!!
