Advice on riveting moving joints
I've been prototyping some very basic steampunk mechanisms that I'm preparing an Instructable for, and I'm looking for a bit of advice on how to make the moving joints.
The mechanisms are simple, with parts I'm cutting from brass sheet myself. They'll be using joints that I'd like to make reasonably permanent and low profile, yet able to move (elbow joints, for want of a better description). I've not tested it yet, but I've read that putting a piece of paper between the two arms before riveting them (blind/pop rivets) will allow the joint to move once it's fastened together.
I was also considering whether it might be advantageous to put a nylon of teflon washer between them before riveting, instead.
Any advice on whether this type of moving joint would be any good, if it would last with moderate use, whether it would work at all, and what some possible alternatives might be would be very much appreciated. Thanks in advance!
