knotzo

Just got a Landis 3 machine. I've watched all the videos and read everything I could find, but not sure what is causing the rats nest of thread on the underside. I've never had a chance to use one of these machines before, so it is all new to me. I'm pretty sure I have the top and bobbin threaded correctly, as there a some good videos out there. I'm running nylon bonded 346 on the top and 277 on the bottom. Anyone have any ideas what is going on with this machine?
