Comment faire ses plaquettes en jigged bone ? (WIP par Bailey)

I have been making my own jigged bone. It is really pretty easy, so I hesitate to post it here lest people find out that it is quite simple. There is really not a whole lot to it. I basically gouge out grooves in bone and then soak it in potassium permanganate. Here is the WIP that people actually want to see.
Here is the bone as I get it. I usually buy it from Trugrit. It is just your basic cow bone. I normally even up the flats to make sure they are really flat. I also do this after the potassium permanganate treatment (heretofor referred to as the PP treatment, not sure if that is any better, but oh well.)


I picked up a carbide bit for my rotozip foredom thing. It has a bunch of little spikes arranged in a ball. I would love to see a "How It's Made" episode on these things.

Here it is after the first run. I go half way and then turn the scale around to do the other half. Wear a respirator, not only to protect your lungs, but because bone stinks when you turn it to dust.

Here it is half done
Those of you who share lineage with Sherlock Holmes will notice that the last picture does not have a groove in common with this picture. That is because this one is a different scale.

Here are all of them done

Just an off topic shot of some of the stuff I have on the anvil. At least one of these will have some of these jigged bone scales on them.

Here they are ready to go into the PP. I let them soak overnight, then let them dry for a day or two. No one ever accused me of having a neat work station.
