Richard, I have turned a few wormy pieces in dogwood and spalted elm.I think they are a lot prettier woods when allowed to spalt as a standing dead. But I run the risk of borers here bigtime. There was a persimon in the creek I thought they would leave alone and it could spalt over the winter, wrong! I lost the root ball for certain as it was to well eaten to hold air pressure.I did get some cuts up the trunk that may be solid but I haven't opened them yet to see.
I sent GC a spalted elm with the varmint bites in it. They show as full of dust. Call sounded great when I shipped it , no doubt GC will ruin it /ubbthreads/images/graemlins/tongue.gif They show as holes or dusty streaks in the dogwood calls I have turned. One had a hole that went through into the air chamber and it was a surprise when the call blew back in my face /ubbthreads/images/graemlins/smile.gif
When you sand them they seem to loose more of the surface at the hole causing a slight dip in them you can feel but aren't what I would call ugly either.
As for getting the osage and mulberry to hold their colors I am trying submersing the whole call in a clear laquer finsh to completely seal them from the air and moisture. I get a thicker more even coat that way. So far I haven't lost any of that color tone and it's been two months now. I figure if it's going to turn it should do so by fall.I have a black locust predator that is treated the same way and it hasn't begun to turn either, it should get duller and grayer with time if it turns.
