Recently there was a thread on rec.crafts.metalworking pertaining
to the existance of face mills which used regular toolbits instead of
inserts.  I have such an object, and I was asked to post pictures to
the drop box.

 There are three files:

  facemill.txt  - this file
  facemill1.jpg - a machine's-eye view of the cutter head
  facemill2.jpg - a side view of the cutter head

 This item is properly called a face mill because the cutter head is
seperate, and has multiple cutting edges.  Normally I have it mounted
on an R8 shank, but I removed the shank to do the scans.

 The cutter head has a 3" diameter and takes 4 standard toolbits of a
1/2" square cross section.  In the scans you see brazed carbide toolbits,
but any 1/2" toolbits would work.  The cutter head has stubby toolbits
mounted in it, but regular-length ones will fit - the stubbies make it
easier to lay in the coolant, and there's no benefit to the extra toolbit
length.

  Inserting the toolbits can be quite a fiddly operation if you want
perfection, but I just lower the cutter head close to a flat surface and
let the toolbits hang loose so that they all touch, then I tighten the
clamping bolts finger tight to hang onto the toolbits, raise the cutter
head and snug the bolts with an allen key.  I get results good enough for
my purposes.
