I don't know all the proper part names, but this floor frame has a metal piece in the end of each dowel, attached to a wheel with the "teeth" that hold the dowels at the right tension. The wood split where one of the metal rods goes into the dowel, so that dowel slips all the time resulting in no tension - the quilt just unrolls onto the floor.
The frame was my mom's, as is the quilt I am finishing. She had the top pieced, the batting purchased and the backing cut/sewn to fit, but no quilting done, before she passed away. It means a lot to me to finish this quilt; we have two baby quilts she made for my sons, but no larger quilts. I'm looking forward to having a quilt that my mom and I collaborated on, even if she didn't know it was going to happen that way. She was a wonderful quilter, and it's an honor to have the chance to finish this one for her.
I see a quilting hoop in my future....and perhaps some smaller quilting projects so I can learn how to do this right!
