Hmm, sounds more interesting than I thought! I will have to research the swing-needle as I know nothing about them. Ron - thanks, I may take you up on your offer! I did see one of the flat disks on it, but don't know which one. May be a moot point by now, but I'll swing by after my GD goes home and see if it's still there.
I'm so aggravated by my elbow tendinitis! Can't do much of anything until the flare dies down a bit, but at least I can look at the machines!!
Linda, if you live within a couple hours of Richland, WA, I can pick it up and hold it for you...if it's still there. I don't mind!
