Thank you to all of you. I have the original instructions...worn, crackling, but they also have the assembly directions on the website. The rails are adjustable. They seem to be routed. Edmunds does still have the joining plate for the rails. They told me that it isn't uncommon for the rails to go missing. People take the work off and misplace the rails. I honestly don't thing the rails were ever there. The shipping label is not anyone the daughter recognizes. We think she perhaps got the frame at a yard sale of some such. Mawluv, is it possible that you could send me a few pictures..closeups... of the rails?? Edmunds seemed to think I could just make rails that would fit into the clamp spaces.
It is a well made, beautiful frame. I would love to be able to use it.
Thanks to all. The help is appreciated.
