Ways to get a small metal/plastic rod to rotate

[liz blackParticipant @lizblack57272]

Hello there all you lovely people,

I was hoping someone smart could help me. I am prototyping some new jewellery parts (please see image). Basically I need a part to swivel to allow the wearer to rotate the piece – my idea so far is to insert a 'binding screw / chicago screw' then fix the two parts together. I am not sure you can get small enough binding screws at 2mm head, or if this idea is ideal.

If anyone has any other ideas as to how I can get these two miniture pieces of metal or plastic to fix but be rotatable please do let me know !

Many Thanks for your help, I hope this makes sense.

Liz

Hi Liz,

If you can tap/thread a hole in one of the parts, and have a clearance hole in the other, you could use a "micro shoulder screw" to fasten the two. These shoulder screws have a cylindrical shoulder under the head and then reduce down to a small thread. I've seen these down to 1.6 mm shoulder and M1 thread. The non-tapped part will need to be just slightly thinner than the screw shoulder height to allow the part to rotate on the shoulder. It would also need to have clearance for the screw head.

You can try a Google search or Ebay search for "micro shoulder screws" or " micro shoulder watch screws". Good luck. JD

Assuming your items are metal then leave a round spigot sticking out of one part a little longer than the thickness of the other part. Have a matching hole on the second part.

Assemble by placing the spigot into the hole and then give the end of the spigot a few blows with a small hammer to pein over the end so it won't pull out.
