Thank you everyone for your help. I was so desperate I put multiple questions on the board not knowing how active you are on this site. I had paid so much trying to repair a vintage 111w155 which became a money pit with barely any sew time. I took your advice, sold it and purchased a refurbished Juki LS1245 cylinder arm. I have been happily sewing ever since. Sorry for not replying sooner. I am so grateful for the advice I got on here and realized though I am near a large city, finding a reputable industrial sewing machine repair man is not that easy. Seems like you really need to master the skill yourself on your own machine to fix all the previous misalignments. Way out of my wheelhouse. Problem solved, excellent advice, thank you!
