Re: Home made frames
I would place a second pin lower down the bar to prevent slapping. I would also just place a pen on one side of the frame. this would also serve to help keep frames oriented in the same direction.
I have made a lot of frames. I agree they are a pain and they are first on my list of things to not make in the future and just purchase so I am working with the shoulder. I have nearly a thousand of them to make this winter and will probably start placing a nail in them as a spacer.
