Does the Juki DL-555 sew leather? - Juki MO-644D Mechanical Sewing Machine

Ordinary drop feeds are not suited for sewing leather,ideally a needle feed or machine with a walking foot mechanism is best suited.if you are stuck with this machine only,there are a couple of things which may help.on some of the juki ddls there is an adjusting screw and locknut on top and in the middle of the arm of the machine .turn needle by hand wheel to bdc and loosen this screw and turn clockwise slowley! this will raise the presser foot very slightly,so when the feed dog is at tdc it can improve the feeding . spear point needles are reccommended also. one other idea,but you need a qualified mechanic to do this is to alter the feed timimg slightly on the eccentric on the top shaft.as the needle is entering the fabric,slow the timing down so the needle enters the leather just as the material starts to move. hope this helps! cheers kev w 07725903110
