Just thought I'd share that I found the (soprano) Rovner Eddie 
Daniels lig PERFECT for these blanks.  It has never fit any of my 
soprano mpcs all that well but now it has a home.  Just doesn't have 
a cap!  Looks cool, too.

I've got a bit more facing work to do, but I got it to play from high 
F down to about low D without too much trouble.  I've kept the baffle 
high for now, opening the throat with my Dremel.  This is becoming 
one mean mo'fo' from Mojo.

Once I get #13 to play well, I'll tackle #18 with my lessons 
learned.  Like not taking down the table too much.  It's a little 
thin at the window.  Otherwise, it's been an interesting time killer.
