Question about Simplicity Quilter's Classic SW240 Mechanical Sewing Machine
Thread binds up under the plate and can't move the needle up or down. I have to remove the plate and remove a ball of thread that builds up over a projection behind the bobbin

Make sure your needle is threaded correctly and that the needle is not old or blunt.
make sure that the thread and needle size are compatible with the material you are using.Or check with manufacturer.

Our machine had the same problem, there was a piece of broken thread stuck in the upper tension spring keeping the tension spring open. removing the broken thread in the upper tension solved the problem for us

It could be the thread is hanging up and breaking the needle.
Check the thread spool for nicks - turn the spool so the thread is feeding from the bottom of the spool.
Watch the thread as the machine stitches, if the thread is pooling at the base of the spool, use a thread net on the spool.
Open the needle plate and remove the bobbin and bobbin case - clean out any lint or thread snips that may have accumulated there - do this often to help the machine work as it should.

I sounds as though the needle is not properly installed.
Replace with a new needle. Loosen the wing nut so the needle can be easily inserted into the holder as far as possible, with the flat side of the needle shaft facing the back of the machine.

I agree, the machine needs to be serviced at a sewing machine shop

Testimonial: "After taking the slide plate out and removing the bobbin casing, I rotated the hook to just behind the needle and tightened it a little, by turning my hand wheel, and it worked. Yeah!!! Save me precious $$$$$. Thanks so much."
