The very first vintage sewing machine that I bought, came home in its cabinet. I just hoisted the whole kit n kaboodle into the back of the van. I was unaware that the head could easily pop out of the cabinet. Such activity damaged the cabinet. I have repaired it but I sure do wish I had known about this in the first place.
I may have covered this in a previous post but nothing pops up when I search. I am not in the mood to scroll through all of my posts so I am providing the information here, again or for the first time.
I am a member of the FB group Vintage Sewing Machines. There, someone inquired about removing the head of the machine from a cabinet. I took pictures of the set screws on the Monty Ward HA-1 I just serviced. The concept is the same for a cabinet machine. If there is wiring attaching machine to the cabinet that wiring will also have to be removed from the machine. This photo shows the basic concept of set screws in the machine that hold the hinge pins tight. Tip the machine back, out of the case or the cabinet. A good flash light helps a whole lot. Identify the screws in the back of the base of the machine. Circled in the photo below.
