My dad helped me to make one like my granny used to use. Just 4 long pieces of wood with holes drilled through at an angle all the way along and a clamp at each corner. You tack the quilt to the frame through the holes, adjust the clamps to make sure it's tight and balance it on chairs at each corner. Then you start quilting at the bottom and take out the tacking as you go along so that you can roll the completed quilt up around the bottom piece of wood to reach the middle. I've only used it for hand quilting, but I'd imagine it would work for machine quilting too if you could get the frame balanced at the right height for the machine.
