I could not wait after loading my quilt onto the frame. It's quilting smoothly and with no drag. I did get a message from another person that had done the same thing. She suggests putting electrical cord (like lamp cord) in the groove and then putting the steel bars on top of that. She has done this to keep the bars from settling into the groove over time. I will do that after I get this quilt finished. Sure hope that this is the answer to the problem that has been driving me crazy!
