Thread: Pressure Fitted pins

As Ben.mid has pointed out, it can get a nice clean look.

I have a way of doing this, take a look at this thread:http://straightrazorpalace.com/galle...-smoke-pc.html

There I have filed the pins flush with the scale material. But, the scales need to be thick enough to allow at least 1-1.5 mm of tapering to make enough "coning" of the pin. Also, this metod stresses the material a bit, so I doubt that grained materials such as ivory and bone is a good choice. Perhaps some wood spieces can be used, just test away!

how does one taper? did you use a countersink bit?

khaos;

Here is one way to accomplish what you want to do.

In the first attached image you will see the idea in the rough. Simply stated: glue in some brass inserts flush with the surface of the scales. Then, take a center drill of the appropriate size (see second photo for illustration of same) and drill almost through the brass surface plate to form the conical 'stop' hole for the peened over rivet pin. The take your ordinary drill and continue on through to make the scales ready to take the pin.

The diameter and thickness of the inserted plate need not be very great. Also, there are many materials which will lend themselves to this task, although I would tend to choose for a metal, in particular either brass, nickel silver or silver. These are soft enough to work easily, strong enough to serve for the intended purpose and cheap enough to reasonably afford. You might also choose for a hard plastic or resin impregnated substance.

This approach does require that you do a bit of careful inset and gluing work, not to mention carefully filing away the top of the peened-over pin after the hammering operation with subsequent polishing, but it will give you the effect you want.

I use exactly those bits ignatz so kindly has attached photos of, 1.6mm centerdrill. Makes a nice tapered hole.

Nice drawings by the way, ignatz, and of course that is also a way of doing it, in fact when it comes to grained materials it's probably much better also!
