bylinesupplyco Report post Posted September 3, 2015 I just recently got a Cobra class 4S and have been amazed by what it can do. I have been sewing wallets with 3-4oz Wickett and Craig English bridle. The outside presser foot is leaving impressions all along my stitching lines, even after I have adjusted the pressure foot pressure. I think I've loosened it almost as loose as it can go, and it still seems to be leaving marks. I dont want to loosen it more, as I don't want the fixture to come out as its spring loaded. Has anyone had any issues with this? If so how did you fix it? Thanks in advance! Quote Share this post Link to post Share on other sites

silverwingit Report post Posted September 6, 2015 As fast, accurate and convenient as Juki 441s and their clones, or for that matter any industrial leather stitching machine, are the presser feet do leave marks. Unlike lesser machines, your Cobra 4S has a smooth feed dog that won't marr the underside of your work piece. Still, in order to pull the needle out of several layers of leather, the presser foot must exert some degree of pressure on your work piece, otherwise the work piece will be pulled up off the feed dog and create havoc (if have you've ever forgotten to put the presser foot down before you began stitching you know what can happen). The best solution I'm aware of is to use the minimum amount of presser foot pressure that will still get the job done and then to go over the resulting presser foot marks with a modeling spoon to minimize them. If you want ~no~ presser foot marks whatever, you will probably need to hand stitch your projects. Good Luck, Michelle Quote Share this post Link to post Share on other sites
