Thank you for the response! Much appreciated! This machine has been pretty much trouble free in my lifetime. Were you able to watch the video? I downloaded and printed the military manual and some illustrations were scrambled. Lubrication drying out? Does the needle bar get moved by a cam? Gets pushed on way and spring return? I'm attempting to wrap my head around how dried lubrication can cause the needle bar to act this way. Dan

I have my late dad's Singer 111W155 commercial sewing machine. He purchased it new in the early 50's. It's sown a lot. One day it wouldn't stitch. Needle wouldn't go through the hole in the feed dog. In fact the needle bar and feed dog don't move together. Broke the needle. I'm the only one who uses the machine. I've looked the machine over for something loose or broken and didn't find anything. The timing belt is in time and in good condition. The military manual hasn't been much help. Some of the pictures are messed up. I made a short video attempting to show what happening. Thank you for your thoughts! Dan_In_MN Link to video. https://youtu.be/tBfok3Zu-Vk?si=d66XIaR5rbtZs0Af
