      er collets will work - you just need to get an "ERx R8" shanked chuck for
      it. (x=series of chucks, e.g. 16, 32, 40)

      <http://www.fignoggle.com/tooling/hold-erCollets.htm>

      while the r8 collets are a great way to get your toolholding needs met due
      to their low cost and availability, the ER collets offer flexibiility in
      the continuous holding range meaning you can even chuck drill bits, edge
      finders, etc.. since buying the er32 set for the x2 mill, i stopped using
      the drill chuck!

      the x3 will the r8 spindle will work with any r8 toolholding equipment
      including an ER collet, provided that the shank is r8 and not MT taper or
      other.

      hope this helps.

        i went to visit dick stephen(who has been doing the MEW X3 articles)
        a while ago and he had kept the x3 in preference to the wabeco mill
        that he already owned. i seem to remember that he found the extra
        weight made a significant difference, i think he said the wabeco
        head was cast aluminium rather than iron. his x3 was immediately
        stripped and rebuilt from new.the grass always seems greener though,
        doesn't it

          I suppose it's possible I had a poor example of an X3, but
          the cut volume I can achieve on the Wabeco is definitely
          much larger than on the X3. In fact, my current X2 can do
          almost the same cuts without chatter that the X3 could do.
          Beyond just chatter, the X3 head would shake rather violently
          if I cut too deeply. If I overdo a cut on the Wabeco, I get
          no such behavior. It is as solid as a rock compared to the
          several Chinese machines I've had. I always thought the head
          on the X3 was not mounted rigidly enough, even though mine
          did not appear to have the gib fit problems that some people
          report.

          It is true that the Wabeco is much lighter. I can lift the
          thing by myself. However, from my experience with the two
          it's obviuous that the engineering of the machine is more
          important than mass alone. I'm sure with the same design
          more mass would win out, but in this case the Wabeco is
          clearly the more capable machine.

          ... Alan, the fit of this gib (or rather the lack of its fit) is indeed the biggest single source for chatter on the X3. Chris
