N/A The square frame of the Port-A-Press™ can either be inserted in a bench mounted vise or in the channel shaped holder provided with the press which can be mounted to a work bench. The press can also be operated by laying the frame on the edge of a table and holding the frame with one hand while the torque wrench is tightened with the other hand. Pressure is applied to the die set as the threaded lead screw and toggle pad assembly is screwed through the threaded frame using the torque wrench. The torque wrench easily generates 20 foot pounds of torque without the use of excessive strength, which is sufficient to produce 16,000 lbs/in² of pressure on the die set. This is the equivalent of 8 tons of pressure and forms a very clear pellet. The anvils of the 7mm die sets are hardened with optically polished faces and use the same aerospace grade of nickel based alloy as the Quick Press with which they are interchangeable. The dies are loaded in the same manner as the Quick Press die sets.
