That will definitely help in the future, Father.
I have just use an empty medium box with a piece of plywood under the inside of it to raise the frames up. Now I just use a short box. I also add 2 3/8 wood strips on the 2 short sides to force the frames to stay straight. It only does 10 frames at a time.
I bet I have made 3 to 4000 frames with them maybe more.
