Sturmtrupp702 Report post Posted June 14, 2019 Recently my econosew 2060e8bld had some thread get wrapped around the bobbin case and I didn't notice it till the needle wound up wedged against the edge of the bobbin case and at the time I thought best to get everything unbound by loosening the set screws on it so I could get the needle unbound and get the thread out and now I cant get the needle to not brush against the bobbin case as it comes up any help would be greatly appreciated Quote Share this post Link to post Share on other sites
Matt S Report post Posted June 14, 2019 (edited) Those grub screws control not only the hook timing but also its spacing from the needle. First check your hook timing, and adjust as necessary. Upholstery-weight machines like yours I tend to time so the point of the hook passes the needle scarf at or just after the centre of the scarf. The easiest way to adjust, in my experience, is to tighten the grub screws just enough that it won't move without deliberate effort. Then, holding onto the hook with one hand and the balance wheel with the other, you can make some surprisingly fast an accurate adjustments. Then adjust the hook spacing. With the largest needle I'm likely to use I like to tweak it so that the hook just kisses the inside face of the scarf, then back it off enough to just not touch, if you see what I mean. I believe the technical term for this amount of clearance is a BCH. If everything else (needle bar height, foot timing etc.) is good that should get you pretty near bang on. With a horizontal-hook machine like yours, this can be a very frustrating 5-handed job until you've done it a few times.
