Beautiful, beautiful work. I am using teak (scraps) to do the same thing. Had to mill them down 'cause they are far too thick at over 1 inch, +1/4 or so. Be sure to oil the wood well before using for long term storage. The 1X4s I've used in the past rusted some of my dies. Not too bad, I caught it in time. The most impressive part is seeing independant thoughts combining wood and metal working together.
