We have been hard at work on Brian's wall installation and I am here to update you on it's progress!
Notice, he didn't cut through the slab; there is still some thickness of wood to serve as a shelf or base to glue the bone to. This way, the spiral arm will be pulled up to the same level as the rest of the slab when the bone is glued into place.
Now it was time to glue the bone in it's new fitted home. You can see the West System materials Rob used to make the epoxy resin concoction that he used to hold the bone in place. He smeared it into the routered hole as well as on the base of the bone. I noticed he was careful to make sure to use the right amount; thus avoiding the potential oozing factor. He taped around the hole in order to keep the resin from getting on the surface of the slab.
In order to fit this thick piece of wood into it's tightly-cut hole, we needed forced stronger than what our human muscles could provide. So, using two C-clamps, Rob slowly pushed the bone into the hole. He made sure to tighten the clamps at the same rate so that it lowered into the hole at the same angle on both sides. It's not pictured but, he also made sure to put a piece of wax paper and a caul between the clamp and the bone itself. This way, there would be no chance of a mark being left from the small circular pad on the clamp and/or any issues with resin squeezing out onto a place it shouldn't be. It was a tight fit and you could see the spiral arm slowly pull upwards to match the level of the rest of the slab. That is what I call a successful, functional, and class looking bone.
As you can see in the photo below, now that it has been leveled, the bone looks so nice and natural holding the gap together. I think the tone of the wood is subtle but adds such an interesting detail. Kudos to Rob on a job well done!
Since this slab will be a wall hanging, we want the surface to be free of marks so it can be admired. Furthermore, we want to make sure the surface is smooth so that the finishing materials dry evenly and cleanly. Man oh man, when we were done, the wood surface felt like marble.
