February 26, 20206 yr Many years ago I made this 12" dia embroidery hoop. To use it, set it between your legs using your leg weight to hold it in place. It has 3 adjustable joints and three finger bolts to hold it in place. Over the years the friction hold points of the adjustments have become too smooth and it slips. If I roughen up the friction hold points, they will soon be smooth again. What can I do to make these adjustments hold? I've tightened them VERY tight by hand, but they still move. I've thought about very thin washers with rough surfaces, don't know where I'd find something like that. Any thoughts would be appreciated.

February 26, 20206 yr Author I had a lot of problems getting the pictures to download. Finally it accepted them.
February 26, 20206 yr How about make a washer from some self stick sand paper? Or add some finish and throw some sand on before it dries.
February 26, 20206 yr Self stick sandpaper like Dan suggested works good. I cut them to size like a washer on both sides. Used 80 grit sandpaper.
February 26, 20206 yr I actually would go the other way around. Put metal washers on the outside to keep the metal bits from sinking to deep to be tight. With the metal washer on the outside the clamping pressure will surely hold tight. If not then yes some self made sandpaper washer are the way to go but will be temporary.
February 28, 20206 yr Green felt paper. Green very thin felt with sticker paper on the back. Available at craft stores. Two pieces inside and two pieces outside with the green felt facing each other will give you the friction you need.
