New Churchwarden Pipe

Just finished turning this pipe.
My Daughter bought me a Tap and Die set for Christmas how did she know?.
I wanted to make a pipe with interchangeable bowls for a while now.
I had experimented with press fits but had no luck.  
Now  i will be able to make other shape bowls to screw on to the stem always tight and sealed.
As always when i turn a pipe for myself  the block had a few inclusions and a small crack go figure.
Andrea said that wood is a natural product and that i have to get over it.
And the inclusions and cracks add to its uniqueness and beauty.
