Here's a little more eye candy. This is the underside of the plate.
Today's a rest day. Gotta pay some attention to the dogs and then I'll do some heat treating and shop cleaning. I spent a good day on that thing yesterday and getting punch drunk from it. (CNC would fix that).
Can't tell you enough how valuable the power down-feed and auto-stop feature on the mill was for this. It did all the drilling and countersinking. Didn't even wear-out any of the bits much less break one. The metal is soft as butter though. 1045 that been fully normalized (spheroidized state). The only thing I had to do by hand was finish the inner circle of holes -lest I drilled into the rotary table. The rotary table is 6" diameter. Sometimes I wish I had a bigger table but this one is so easy to heave around etc... Anyhow, for the inner circle of holes, I set the auto-depth to 85% depth and finished them off on the drill press.
BTW: I got an unusual PM from someone about this and some of my other demonstration projects so let me explain... I'm well aware that nothing I'm showing is rocket science and I try to give decent verbal descriptions and show pictures to help some of the folks that are learning this for the 1st time. Some people learn with pictures some folks need written words etc.. I wish I could show you the turbine engine I'm working on but, it's self-designed with some "interesting features" that I feel are marketable -so, the interesting shop photos are not put in the public domain.
