I have done the same thing with my spinning wheel, many times. Fortunately it is a diy fix there!

Thanks for the warning. I would not have thought of this!

I have the exact machine and Yes! this happened to me. I left a spool of thread on the spindle to fill bobbins. I noticed that thread on the spool was winding and I thought that's odd. I realized it was going right to the fly wheel. It was a full spool of Aurifil and it was half gone. I started unwinding the thread but after 20 min. I was bored with that taking it slow so the thread wouldn't break. I took the housing off my machine and cut the rest off the shaft. It wasn't hard to get the thread out. I'm glad it wrapped in a spot that didn't cause the machine to bog down. Also the at little space where the reverse lever is? Well a pin got in that hole somehow and fell to the bottom and stopped the gear from turning. I took the machine apart and there was the yellow flat head pin stuck right in the gear. I took it out and the machine worked just as before. I don't have any fear at all about taking this machine apart. I have saved a small fortune finding the problems myself.

Wow you are braver than me! I also see a crack in the reverse lever. I am going to glue that as I bet its the same deal about replacement. I love that Brother and sure couldn't do the stuff I do without it.

Thanks for heads up!!

Sorry to hear about your tragedy. But thank you for sharing...I use the large cones a lot and seldom pay attention to where they are placed...I will definetely be checking often and making sure nothing like that happens.

Wow, who knew?? Thanks for the heads up. I leave my cones by the machine all the time. Guess I've just been lucky. You can bet I'll be moving them!

Just curious. Do you piece and sew with the cone thread made for serging or are you talking about some other kind of cone? I worked for a Bernina dealer who made her bread and butter by doing custom dressmaking and alterations. We never used cone thread meant for a serger with the machines in the shop. I know that they now make cone thread for longarm machines but it is not the same as serger thread. I purchased one of those little machines to wind bobbins and I love it. I always hated to have to unthread my machine to fill a bobbin. I got the one made by a man in Floridia. It is not only very useful but I kept the money here in the good old USA.

The cone was a regular poly cotton I had been using in some custom sewing. It works with all my machines including the serger. I guess that any cone or spool could do the same thing it it get into the wheel where its not suppose to be. Note to self....clear the table more often. LOL
