My Pfaff hobby 1200 keeps breaking the thread while free motion quilting.

SOURCE: thread keeps breaking and thread sometimes

I am guessing here because I don't know what kind of thread you are using but, I am guessing that you have something in the upper tension discs causing the thread to not have tension, first I would recommend if you can see in to the disc put the foot in the up position and and blow out the disc. If this doesn't work take it to you local dealer and have the tensions adjusted, also look at the needle plate and see if there are marks in the hole, if there are it would be wise to either clean them out or get a new needle plate they will severely affect free motion

Hi Jeanette! You have a Singer Featherweight--the best sewing machine ever made! (Mine dates from 1950/51 and I wouldn't trade it for the world.) These beautiful, sturdy machines were designed to be easily repairable at home, but you'll need a copy of the Service Manual (get the Instruction manual too, if you don't have one.) Go to www.singer-featherweight.com and check out what they have available.

I had a similar problem (needle thread not catching the bobbin thread) and the problem was that I hadn't put the needle in correctly (flat side to the left). Also, I will occasionally get thread wrapped around the bobbin housing--sewing along just great and then everything comes to a screeching halt. I'm not sure why that happens, but I'm getting pretty good at taking the bobbin housing apart. The manual is pretty clear on how to do it. You can contact me direct at [email protected] for more information.

Thanks!

Robbie

SOURCE: My Pfaff 4.0 breaks needles

a sewing machine I work on last week, I put a new needle in the needle clamp & thought I had it correctly inserted,, but it wouldn't work,, so I went back & checked the needle again & found I had to unscrew the needle clamp screw even more than normal to insert the needle then it work perfectly.

some needles & thread don't work togeather--here's a tip
Cut 6-8 inch piece of thread of the spool you are going to use for your project
Take the needle you are going to use for the project
& insert the thread thru the eye of the needle
& lift one end of the thread to a 45 degree angle
& if the needle is the right size for the thread it will slide down the thread
But if the needle hangs on the thread you need one size larger needle for the thread

also clean under the needle plate where the feed dogs are for lint
& also in the bobbin area for lint & loose threads

this is a known issue with the pfaff.....i have just bought the machine and it has thread uptake issues...thread tension issues and it comes unthreaded by itself often...leaving globs of thread on the bottom stuck in the feed dogs and under the throat plate.....then the stitches are not properly balanced because the tension gets too loose on the bobbin thread....very disappointed to find out it is a known issue with all the viking husqvarna made machines...which are pfaff, janome and viking.....sux.

Its the frame, its the open metal frame. I have two machines and have the same problem. Heavier thread, changed needles, raised and lowered. Its the frame you need to frame in like a box and it will work or turn it upside down and ask you husband to screw a large piece of plywood to the bottom to make it square and heavier. The frame will continue to float around, we even screwed it to the floor. For three years I had to go without the quilting. Machine works off stand not on.
