Members EdwardHBLW Posted November 30, 2011 Members Report Posted November 30, 2011 So For a good while my machine was working great! Recently, I shortened up the stitch length for a project, then put it back to how I normally have it... since then, the tension's been all wonky. No matter how loose I have the bottom (1 turn from pulling the screw out) and how tight I have the top thread, the bobbin side still seems to be way too tight. Any thoughts on what could be wrong? It started with doing it on random stitches, and now it does it on almost all of them. Here are some pics attached. Thanks in advance! Quote
dirtclod Posted November 30, 2011 Report Posted November 30, 2011 (edited) This is just a guess on my part. Make sure it threaded right, that the thread isn't caught anyplace, put a new needle in and make sure it's in right. Tighten the bobbin back up to where it's close to where you started. Loosen the top tension maybe back it all the way off and slowly tighten the top tension sew some and see how it looks and keep adjusting the top tension. If their is more than one place to adjust the top tension adjust them at the same time. Just about every time i had had problems like yours it was because tension was to tight. Maybe somebody that really knows will come by. Edited November 30, 2011 by dirtclod Quote

Did you change thread for the project with the shorter stitch length? If you did the thread you switched to may be the opposite twist. Quote
Members EdwardHBLW Posted November 30, 2011 Author Members Report Posted November 30, 2011 Thanks for the response, guys! I've tried setting tension up top and below to basically all the way off, and the stitching still looks off. The thread has been constant at 207, and needle is 23. The thing that kills me is that when I do a test piece, it looks great for 6 inches or so, then that's when the stitching starts to look wonky. All the thread I use is from Bob at Toledo, so I'm pretty sure it's the correct twist... Quote
Members leatherdog Posted November 30, 2011 Members Report Posted November 30, 2011 207 is a bit heavy for a pfaff 145. 138 is more like the upper limit. does it sew ok with thinner thread? also, what is a size 233 needle? a 160, 180 or what? you might monkey with the thread take up spring, and get a heavier pull there. but i would still go back to the thread size as the culprit.

Members EdwardHBLW Posted December 2, 2011 Author Members Report Posted December 2, 2011 So what happened was a screw got vibrated loose in the hook assembly (not sure the technical term). Got it back from the shop and she's running good as new! I know the 207 thread is a little on the upper end, but this machine is just until we can afford the cost of a new Cowboy, Techsew, or a Cobra... Quote
