I have recently purchased a Tree 2uvr-c vertical mill and would like to
use an indexable face mill. What size arbor do I need to purchase? The
manual says that it takes a #2 Morse Taper or a #7 Brown & Sharp.

thanks in advance,

A very small one. No bigger than about 2" in diameter. Its been my
experience..and others may have different opinions..more learned
ones..that the incredible side and torque forces a face mill places on
the taper can/will bend a small shanked holder such as the 2 and 7,
over time. Ive already damaged a 30 taper face mill arbor, turning a
4" face mill. Bent it actually. Not the body..but the attachment
bolt.

My booboo..shrug.

YMMV

=============================
Building on Gunner's observations, you may be better off using a
fly cutter. There are several types from the typical single
lathe tool unit to more complex ones with both roughing and
finishing tools. There was a thread on this within the last few
weeks. Being a cheap-screw, the biggest advantage from my point
of view is being able to resharpen the 75 cent HSS lathe tool
with the geometery I want. If you want/need carbide, use a lathe
tool with #2 insert for better shock resistance.
