Rubber Hand Stamps
Set up the desired name and address in common
type, oil the type, and place a guard about one-half inch high around
the form. Now mix Plaster of Paris to the desired consistency, pour in
and allow it to set. Have your Vulcanized Rubber all ready, as made in
long strips three inches wide and one-eighth of an inch thick, cut off
the size of the intended stamp. Remove the plaster cast from the type,
and place both the cast and the rubber in a screw press, applying
sufficient heat to thoroughly soften the rubber, then turn down the
screw hard, and let it remain until the rubber receives the exact
impression of the cast and becomes cold, when it is removed, neatly
trimmed with a sharp knife, and cemented to the handle, ready for use.
