SOURCE: bobbin bunches up
Classic burr on the hook problem would be my first guess. If the thread remains on the hook when it makes the next revolution all sorts of ugly things happen such as you described. I made a video that might help.
SOURCE: bunching thread underneath
When your thread is bunching at the bottom, your top tension is not tight enough, or you did not thread the machine correctly. Make sure the thread goes through the tension blades. Check your manual how to do it properly. you can check if there is any tension by pulling on the thread before threading through the eye of the the needle, and with the presser foot down. By pulling with the left hand and adjusting the tension with the right hand you should be able to feel a difference. Normal setting is between 3 and 5

From what I gather on other sites, your thread has to be threaded under tension.... You have to make sure you hear a click when your bringing your thread down to the bottom of the "arm". Also, I thought the bobbin case was rather loosely held in its place, I adjusted this by unscrewing the black plate and moving it over just a smidge. The bobbin is supposed to have some wiggle room, but it kept popping up and making the tiny adjustment seems to have done the trick....for now...
Oil it! Put a drop of oil on everything hat moves every eight hours of operation," except plastic gears etc". Use only Singer oil on Singer machines. Plastic gears require a grease made from plant.. "Do not use petroleum based oils or grease on your machine,it will dissolve the plastic gears etc". used in your machine..
Testimonial: "but the manual says do not oil this machine"
