1. Place loctite adhesive on rock and wood slab 2. Press together and let adhesive set  3. Place wood block in saw vice 4. Cut (stay outside the adhesive area)  5. Remove butt ends by soaking in water 3 or 4 days.  6. Remount butt end to wood surface flat face down using water glass adhesive. Dry and recut to thickness.   7. Put cut slab into water and dissolve water glass adhesive over 2 to 3 days. |

What Loctite product are you using for the first step. Curious which one gives a clean release after a 3-4 day water soak. A lot of products can do the adhesion part but you may end up losing a chunk of the stone also.
Thanks in advance, Al

Well done victor1941! I always wondered about this myself. I'll be moving this into the tute section after a few days. If I forget- do remind me.  |

The product is Pro Line 8X Fast Grab Premium adhesive. I have done several hundred pieces of petrified wood and agate and did not have any pullout unless the rock was fractured. This method also works great to get a flat cut on bouquet plume nodules that have odd shapes. I have used the metal grabbers but sometimes the rock would pull away and damage the blade.

Thanks for the quick reply, going to give it a go this week. Al |

I have heard people using sodium silicate to glue cut rocks to wood for this purpose as well. Then soaking the whole thing in water to release the stone.
The gluing process is great for already cut rocks. For uncut rocks difficult to mount in a vise you can take a shallow container and put the stone in the container oriented for the way you wish to cut it then fill the container with plaster or Paris or cement and allow it to dry. Then you can pop the stone and its new base out of the container and mount it in the vise using the base to keep it in place for cutting.

Vegasjames, I have used this method as well for smaller Bouquet agate where I tried to orient the stone in half gallon milk containers and been successful in cutting. The only problem with plaster and/or cement is the saw waste killed the lubricant very fast and turned it into a sludge.
