Last summer, I burned up a fresh end mill on aluminum because I skipped the coolant. The tool change and recut took longer than just setting up the coolant system would have. Now I never run dry, even for a single part!

Not that crowds can't have their moments...

Ha! Your post reminds me of the time I tried to make my own casings from scratch. I thought it would be easy, but boy was I wrong. I ended up with something that looked more like a balloon animal than a sausage. The dog was thrilled, but my dinner guests were not impressed. I learned to love the magic of a good snap after that.
