Petrified Wood Project Update

In my previous post I showed the slabs of petrified wood with the shapes I had defined using a marker. I have a combination of pendants, ear rings and a couple of rings.

It took me two days to rough cut all the shapes using a Cab King trim saw and my Hi-Tech 10 inch saw with a thin blade to accommodate some of the larger pieces. I was really pleased with the results since I started with 55 shapes and only lost two due to shattering along fractures. Here's how they looked then.

This morning I switched out the trim saw attachment for the right hand wheels on my Cab King and got busy grinding off all the excess material using my coarse (80 grit) wheel. I was amazed at how fast it went and now they look like this.

So now I am ready for the next step where I will use my 220 grit wheel to do the final smoothing around the perimeter and grind off rock on top to produce "domes" that will allow the rocks to polish. This is a much slower process but it is worth it to get stones that are well shaped because any flaws introduced now can't be undone down the road.

I continue to be really impressed with my Cab King, especially the water delivery system and removal system. And it is really easy to convert back and forth to the trim saw.

Stay tuned for the next step in this rather large project!
