it really needs to be dialed in to just the right tensions and settings. I cursed and regretted ever buying it for the first year or so, and then one day I quit being the typical guy and just read the dang directions. Once I had the top and bottom tensions adjusted correctly and the stitch length and foot pressure worked out, all my problems vanished and I was tickled to death with the Boss
Ed...congrats! Hope this is a real boon to your work. As discussed above...I think a nice tight lock-stitch is better than a sloppy saddle-stitch...Enjoy!
