I appreciate the response(s) as I wanted to know before I hand threaded the 2nd rod an 1 3/8" on both ends (ouch) that I wasn't wasting my time. I went with 3/8" rod as that was the sames size as the rods on the edge guide.
I was concerned about sag and that was part of the reason for reducing the length. Length and also hands being roughly 3 feet apart when using the skis.
Harry I believe I see a simple flat washer on each side of the feet? If so, just checking that when hand tightening the wing nut that the rods don't slip.
