Scott, Do you have a 6' table or a 10' table? I learned the hard way on my 10' Gracie frame that if the quilt is a bigger size, then the take up rail can sag a little in the middle & cause extra tension where it rubs on the deck in the throat of the machine (because of the long span). When this 1st happened to me I thought it was my machine causing the thread to break or bad thread. I took my new Pfaff machine back to the sewing center & they couldn't find any problems with the machine. I ended up figuring it out & it wasn't the thread or the machine. Each end of my take up rail was at the same height but the sag of the take up rail made the material rub as I got further towards the middle of the table. I have found that a putting a plastic footstool on the table (at one end) to support the "takeup rail" helps. I place the stool on the other end from where I'm starting about 1ft from the end. Of course you have to move the stool to the opposite end when your quilting has worked over to the end where the stool (or support) is located. This relieved the problem of the thread breaking & relieved problem of tension being forced out of adjustment due to the drag. When I use the support it doesn't matter how fast I go. It was a hard trial to learn this & I think if the take up rail could be solid & unbending the problem would go away. I have been meaning to write the Gracie Co about this to see if they have improved the take up rails for the longer tables. They have always been fast to respond & very helpful & I have been meaning to contact them for awhile now about this (I'm bad for not doing that because how do they know there is a problem unless you tell them). If you have a longer table this may help for now. Ultimately I think the take up rail would be better if the 2 pieces that are joined to make the 10' take up rail were joined with a "longer inside connecting piece" for added support or a "one piece" rail was used out of a material less likely to sag in the middle with the weight of a larger quilt. Hope that helps for now to anyone with a 10' table. When I do smaller quilts on my 10' table I don't have the problem.
