I have been working on some new pieces that have moving parts with rivets in Sterlium. The piece below is a spinning pinwheel ring. I have now made a few of them and I am unhappy with the movement of the pinwheel as my preference is to have a free moving pinwheel that does not wear down the post, open the drill hole or wobble over time.
I used a 2 mm thick wire drilled through and soldered to the ring. Also filing the ring a bit flat where pinwheel contacts ring. I partially fold pinwheel prior to placing over post. Hole is tight to post, rivet and then close. I tried inserting a card stock between the top of the rivet and the inside face of the pinwheel and once closed removing the card. It does not move smoothly and sticks a bit or rubs more in one place. Perhaps inserting some sort of thin plastic disc between the ring and pinwheel?
Not too sure and advice would be most helpful.
Have a great day…
Warm regards from snowy Ontario!
