I helped Aaron mill some brass on the Bridgeport last week. We had to lean the head over to mill the 45 degree corners. I don't think I had done that before with this particular mill. I think he learned a lot from us doing this (and I am always amazed at how much I learn anytime I help a student). Then we went and silver soldered the beast together. We had to get it really hot to solder (as you can see from the water droplets in the slot he milled). He's still working on the other parts of this, but it should be finished soon, but probably not soon enough for him at the moment.
