Halfway there.

In this day and age of iPhones, nano-tubes and what not, it's easy to overlook some of last century's high tech, like the CNC-mill. In essence 1970's technology (invented in the 50's), it still makes my mind boggle at the sheer precision of the thing. I understand the basic principles of it all, but the way it moves in 1/1000 mm increments back and forth, and even more amzingly, mills perfect circles in solid blocks of metal is just astounding to me.

As you can see, the upper triple tree is almost there (lower part of picture), while the lower tree is still a big, but not heavy, piece of billet.
The difference in weight between these and my steel prototypes is amazing. Next up: machining the "slots" and the threads for the bolts that will tighten the clamps around the fork legs.
