Can't get plate off over feed dogs on 503 a singer
Q: [You ask, how to remove Singer 503 Needle Plate].
A: (1) It may help to remove the needle, so you do not hurt yourself on it. Also, removing the Foot for more visibility may help. (2) Pull the Needle Plate Control Lever to the Far Left, as far as it will go. [Singer 503's and all 500 Series sewing machines have a Needle Plate Control Lever, located at Right-Front of Machine Bed, that controls the Needle Plate: (Far Left) To Rise and Unlock to Remove the Needle Plate; (Center) To raise the Needle Plate To Darn [instead of Dropping Feed Dogs, like most machines do]; (Far Right) To Lock-Down for sewing. (3) Grasp Needle Plate with your Left Hand attempting to slide it Frontward or Backward to remove it; at the same time using your Right Hand to move Handwheel back-and-forth to get Feed Dogs to drop down far enough so Feed Dogs do not Bind the Needle Plate, keeping Needle Plate from sliding Forward or Backward to be pulled free of the two Needle Plate Lifting Posts. (4) Keep jiggling the Needle Plate toward you and away from you while dropping the Feed Dogs by means of moving the Handwheel; not being afraid to tug a bit to pull the Posts up a bit more till the Plate pulls free. (5) It may be necessary to oil the posts and work them up and down a dozen times to be sure they move freely through their entire range of motion, before trying again. Hope this helps.
