WARNING --- This one is for you new people, and pros too. What you are seeing is one continuous chip created by that drill bit. It is the size of a baseball and as sharp as any razor blade you can find. It will tear you up in a heartbeat. Stop once in a while to clear the drill bit, you won't be sorry. A trip to the ER for stitches is not fun.

And I pray this isn't what prompted the Public Service Announcement, Bill!
I stop feeding for a fraction of a second, barely backing up the tailstock or quill and that's usually enough to break a chip. Or, just use parabolic flute drills (on the snmaller stuff) and they break chips pretty good just by virtue of feeding them properly hard.
I'm OK Ken. I pushed that back on the bit to show what happens when you are careless. There is never enough said abour these things. It only takes a blink of the eye and disaster is right there waiting. Our hobby is only as safe as we make it.
Someone on another Forum asked how I transfer holes. I use Transfer Screw Sets. I have many different sizes. The body holds 6 punches and doubles as the wrench to set them. The last pic here shows the dimples (in the red circles) of two holes transferred at the same time.
A random thought -- What if an overarm were added and a plunger type blade holder added to make this a detail saw as well. WOW -- maybe I should stop thinking.
