Dissection Process
Given the construction process of the jack, dissection could not be done in the lab and had to be done in the machine shop (The jack in a vice awaiting dissection). The pins connecting the arms to the top and base were riveted on. To remove them, we used an angle grinder, and ground off one end of the pin allowing the pin to be pushed out. This was first done to the base pins (Matt grinding off rivets on the base pins, Base after rivets ground off ). After this the pins were pushed through allowing the base to be removed. When this was completed, the process was repeated for the pins attaching the arms to the top (Matt grinding rivets off the top pins,Top after rivets ground off). After pushing he top pins out the top could then be removed. After this step the the right arms and the left arm/threaded-arms assembly could be separated. Next the collar securing the threaded rod was removed (Threaded rod with collar). As the collar was pinched onto the rod, removal was difficult. To accomplish this the collar and rod were placed in vice to bend the collar out slightly, a press and later a hammer were used to finish the removal (Collar and rod assembly in a press). With the collar removed the threaded rod could them be removed from the left pin. This last step in the dissection was to remove the right pins and separate the right arms and do the same to the left. The right and left pins had notches that were bend back onto the arms to secure them. To remove the pin the notches were ground off with the angle grinder (Matt removing the notches with an angle grinder). With the notches removed the pins could then be pushed out and the arms separated. After this was completed , we photographed and documented each piece to complete the dissection.
