Just beautiful. I myself make grips from spalted bradford pear. I love the pen and ink appearance of the fungal growth, I will caution you, if you don't already know, that sanding and cutting and especially on spalted woods releases spores than can take up residence in your respiratory tract with nasty results. I use a fine particle bio industrial rated super duper filter mask and have the shop doors open when I work with woods, especially spalted ones. I also change clothes and bathe afterwards. Once I had an allergic reaction to rosewood I was sanding for grips. Rash and hives despite shop apron and respirator. MD trip for steroid shot and oral steroids resulted. Some folks are allergic to contact with the fungi that cause spalting too. Some makers use heat to kill the fungus before working the wood too, so the spalting is halted I have read, but I don't know much more than that about the process. Same precautions have to be taken on the heat treated wood too after it's heated. Beautiful work. I hope I haven't offended anyone by offering these cautions. Don
Working on raw green spalted wood can cause problems to some. Spalting is caused by bacteria in the dead or dying wood. The longer the spalting is allowed to continue, the more beautiful the colors and lines can get. Letting the spalting continue too far and the wood will become almost like balsa wood.
The spalting is stopped by drying the wood. This allows the bacteria to die. I get all my spalted wood stabilized so I really don't have to worry about it. I also have a dust collection system hooked to all my machines. When I'm working I also have a swamp cooler that I turn on slow speed so clean air is constantly being forced into the shop and the old air is going out the open window.
Working on any wood
and creating a lot of sawdust if breathed in is dangerous to your health. One should have a good dust control system if it is something they do regularly. Or wear a good dust mask which can be rather cumbersome.
Someone mentioned buying some spalted wood and having the finish bubble up on them. I suspect the wood was not dry enough when the grips were made from it. It needs to be down to about 6 to 8% moisture content.
