Say I want to make a flexible joint between two pieces of metal. The standard way to do that is something like this:
One side of the joint has a hole, the other side of the joint has a pin/rod.
But if I want to manufacture a joint like this, how, specifically, should I do that with a Nomad?
It’s going to be small but I want it to be as strong as it can be.
The ways I’ve thought of are:
- Manufacture the hole side in two pieces that will be sandwiched together, manufacture the pin side as one piece which will be sandwiched between the two holes
- This is relatively straightforward, no crazy tolerances to keep or anything
- The “hole” piece can’t be made as one piece and has to be held together by some kind of fastener or adhesive, so may lose strength
- Manufacture holes in both pieces, one to receive a pin with an interference fit, the other with a transition/clearance fit
- Requires manufacturing the holes with tolerances for an interference fit
- Requires the ability to press fit the pin without breaking the workpiece
- Requires a pin held to a tolerance good enough for an interference fit
- Use ball bearings on one side
- Requires manufacturing holes with tolerances for ball bearings
- Something else
On the “something else” front, I have a buckle which has a little pivot installed through some method I couldn’t identify. Both sides, top and bottom, look like this:
Anyone have any idea how that’s done?
