I added the other groups to clutter them up the way they do to us.

STOP THAT! LOL. I've been posting metal working questions and projects to
try and get people thinking about our craft again now that the political
**** storm has subsided a little.

The flex you talk about to get an angle has the same affect as a 1 degree
angle with a rotary broaching tool.

The idea with the tool post cross drill part is if its left adjusted in a
tool holder I can just drop it in place and drill a cross hole with no
setup. 10 seconds vs 2 minutes or more to take it off and transfer it to
the mill. I've got three parts I have made that require cross drilling and
might wind up being small scale production parts. One would benefit from a
turning operation afterwards. I can mount a collet in the lathe, but I am
leaning towards putting the 4 jaw on and leaving it in place for all the one
off projects.

Actually the mini lathe CNC conversion may get a 3C collet closer and get
used for some of those parts, but the conversion is only half done and
customers just won't pay me unless I promise to make their parts. LOL. I
am leaning towards also CNCing the small lathe with a 3C collet closer as
well.
