Well, after months of on and off tinkering with my 111W153 and a lot of reading this forum, I finally have my machine stitching nicely with 138, top and bottom.  Ignore the chicken tracks on the sample pieces, that was something else I'm working on. This was basically the first sewing machine I ever worked on to any extent. It took getting it turning freely, putting it in a different table, re-timing the bottom shaft, replacing the hook, hours of cleaning, adjusting, re-adjusting,  you name
