rivets

[DanielG]

I put this up on a sci-fi site and thought that it may have some relevence here. The idea is to make pop-rivets standout. Various sizes of syringe needles and needles and drill bits are all that is needed to make the tools as in the drawing.

The needle or drill bit is anchored inside the syringe so that it is just proud of the end so as to give a starting point for the cut. You can chuck the assembly in a pin-vise or sometimes use the plastic syringe intact.

Some before and after pics:

You can cut deep into the plastic before painting or just lightly to scrape away some paint to finish off. You can also cut a line across the centre to replicate a large screw-fastener.

Great tip, Daniel.

Question- in the drawing, it appears you modified the tip of the hypo needle to form a auger point that will be offset from the center. I assume this assembly will work by the drill tip finding the center, and the "auger" will spin on the center axis. Is this correct?

Yes, that is correct. The unmodified needle will score a line and the modified tip will dig deeper and 'follow' the drill bit. Size is determined by the distance from the needle edge to the center guide needle/bit.
