Drilling brass (and some amazing videos)
John K Jordan
When making a brass handle adapter, I described some problems I had drilling brass, somewhere in this thread. Much of it probably had to do with the brass being work hardened. (long message near the end of this thread):

However, in watching some amazing Clickspring videos about making a clock I was reminded of the value of using a zero rake on drill bits for brass. Here he tells how to modify a drill bit for brass:

For anyone interested in some incredible machining and even some turning brass and steel by hand, the Clickspring series is well done and captivating. He every part in the clock including the gears (wheels), pinions, hardened screws, etc. The first couple of videos:

This one has some hand-turning brass using HSS gravers, at 7:45

and some hardened steel in this one, starting at 3:22

He also has videos on making a variety of tools. These are inspiring if you have a small lathe/mill and like to make tools. If you don't have these, don't watch these videos or you might "need" to get them!
