In pursuit of a good stitch I have had to make some modifications to my machine. I have spent days researching how other mid arms are threaded and adjusted.The manufacturer of my machine is notorious for being unresponsive to quilters who own this machine and who cannot stitch with it. First up has been to set the needle bar to the correct height per other machines. I loosened the screw you see behind the red circle. Then I put a dime under the foot for correct height and tightened the screw again. Over the next few days I will post explanations of other “fixes”.
