Thread: Geneva type collarless pins

Does anyone know how to make the Geneva type collarless pins? How'd they do that??

The modern type are available on line. The bay often has them as do some of the Dovo suppliers. Just a fancy headed nail and a shaped washer for the other side.

Thanks Richard. Maybe I was unclear. I have not been successful in duplicating the original Geneva/Genco pins after I have unpinned a Geneva blade. IMHO Dovo pins look nothing like the old collarless Geneva/Genco pins. Maybe I could chuck up the Dovo pin and reshape the head.

I sometimes use the brass Escutcheon Pins from a hardware store. The shank is often 1/16th inch diameter.

Many hardware stores have them. I also use Brass Finishing nails and pound the head into shape with a ball pien hammer with the nail in a 1/16th" hole in a bar of steel.
I have used a small collet in a dremel many times as a lathe.
I use the supplied arbor that has a screw to hold the washer to make a tiny one.

Small parts Inc on Amazon and also the 'bay may have the #0 washers you want to round and reduce the diameter.

I have tried. I can get a good one with the pin chucked-up in a drill chuck. I seem to flatten them out anyway attempting the other side. Might try a divot block someday!
I am certain they did those with some sort of press. "Ker-Chunk!"

Most are nothing more than small pop rivitts,pure junk IMO

No, Pixel! look at them! I piece pin pinned with a perfect dome from the factory. Both sides! The factory Gencos and the like, had to be pinned by a press. They look and work excellent. Just how to replicate? IMO!

I would think a rivet set would do it. Kind if like a doming block only on the end of a punch.



In this case you would only use the dome part and not the holes for pressing the material to rivet.

And you may have to make a special one for that particular pin ?

10Pups got it right.
It takes a few tries (or math) to get the pin length correct, but after that you use a doming tool.
After you get a good dome going, you can use a vise to do the final lock down.

You can make your own doming tool using scrap rebar, a drill bit, and a dremel round head carbide cutter.

I think they used a tool called a head spinner. Commonly used for finishing the pins on pocket knives, used to be available from Jantz. You put them in a drill press with a corresponding rest underneath.
