Here are action shots of the tools I mentioned the other day.

This is a tool ejector for a Sherline mill or lathe.  The spindle has a #1 Morse Taper to hold a variety of tools and chucks.  The manual says that to remove a tool just tap the draw bolt with a mallet.  Unfortunately, I find that once I have given the thing enough whacks with a mallet all of my adjustable axes are out of alignment.  Here is a low-shock way to push the tool out.  The hole in the back of the threaded rod accepts the standard Sherline tommy bar for extra torque.

This little guy is a special tap wrench for tiny taps.  I find I break a lot of taps with standard tap wrenches.  They give me so much leverage I break the tool before I feel it binding.  And getting the thing aligned is a constant problem.  This tool is small enough so that I can feel the torque.  The mill chuck at the left is opened so that the tap can slide and turn freely in it, but remains aligned with the hole that was just drilled.

Inspiration found from:
[The tap wrench idea was also from that site, but I can't find it now that I'm looking.]

There we go.  No fruit involved at all, more's the pity.

Ah well... I guess the fruit will live another day.

Thanks for the explain-a-pics too!

Ive never milled anything, wood or metal. I think I'm just not that precise. And I've broken many a tap over torquing it! Homemade tools are just cool.
