This is an interesting piece I actually started years ago.  Top and bottom pieces are Olive Wood (as originally from Israel … was an e-bay purchase out of Georgia).  Piece was a little short for a vase so I had the idea of splitting it and inserting a band of Black Cherry in the middle.  It had been almost done at one time but while I was cleaning out the inside after it had already been put together, I ended up blowing out a chunk of the Cherry.  Needless to say, it was headed to the firewood stack when I had one more idea.  I could cut the broken cherry band out of it, install another one and finish it up.  By the time you get it to where your “finishing”, it isn’t easy to get it back on the lathe in any way, shape or form.  I roughed in the next cut and got the new band in place.  The seams were then very rough.  I cut a couple of ‘jigs’ (or working forms) to be able to put it back on the lathe.  I then cut in strips to clean up the transitions between the two woods and inlayed two bands of turquoise to bring it all back together.  Came out beautiful but I’ll never recover much of the time in this one.  We’ll write some of it off as education.
