Thanks for the detailed instructions on what sounds to be an interesting adventure I'm soon to be undertaking, much appreciated Z Before you take the revolving head off, check the feed motion cam for slack motion. Do this by pushing and pulling on the raised foot with the stitch regulator set all the way down until it touches the top of the foot. Every measurable amount of slack motion translates into lost maximum stitch length. You ancient feed motion cam may or may not be replaceable. If it isn't, you can bronze braze onto the puck shape to build up its diameter, then file, or grind, or sand it down for the best fit without binding as you rotate the butterfly handles. The maximum length will be 5 to the inch. There's no better time to rebuild or replace it than when the head is off the machine anyway.

Members Zawlard Posted August 10, 2023 Members Report Posted August 10, 2023 Near as I can tell, using the process you describe I measure 2mm of rearward displacement of the foot and no forwards displacement. Would this be considered alot of slop? And even if it's only a moderate amount I guess Id be inclined to address it since like you say 3 hours ago, Wizcrafts said: There's no better time to rebuild or replace it than when the head is off the machine anyway. If I recall you or another member has a thread describing this type of repair? Quote
