Chief31794 Report post Posted April 28, 2014 I have been sewing on a Needle Feed machine (Boss) for a while, I am pulling the trigger on a Cowboy 3200 today. When sewing a holster or sheath where the welt has been skived to provide a taper with the Boss I had to manually adjust the stitch length as the thickness changed to keep the stitch length consistent, will this be true using a triple feed machine or will the stitch length remain constant as the product gets thinner? On some sheaths this is as much as a 1/4" change when closing a foldover sheath and 1/8" on Bowie Knife type sheaths. I don't normally skive the welt in a Holster unless it is a cowboy style holster but it does happen from time-to-time. Thanks, Chief Quote Share this post Link to post Share on other sites
stanly Report post Posted May 7, 2014 hard to believe one of our resident experts hasn't answered this yet, but most machines do this because the presser feet advance by tilting the bars forward on a pivot. Therefor the higher presser foot is the less it will privot for a given setting. Quote Share this post Link to post Share on other sites
Gump Report post Posted May 10, 2014 Chief; the difference in stitch length will be negligible, as the pivot point is about 8 in up from your work.Stitches will be shorter on thicker leather due to the action of the pivot, but it is only a minor difference. You may notice it but most will not see any difference. And besides it is easy to change stitch length with a luxury machine such as this. Gump.
