  • What am I missing here?

    Am I missing something or what???

    I purchased a couple of used Dorian D35CXA tool post holders. One was a MT3 holder and the other was a 5C tool post holder. The MT3 holder works just fine and easily matches up the the centerline of the lathe. However the 5C holder doesn't. Its like almost 1/8" too high.

    This Lathe has a 14 1/2" swing and uses CXA QC tool holder very well. It's somewhat disappointing.

    Dorian specifies centerline offset in their catalog. It looks like yours is a smidge tall there. If you don't want to modify it, I'll buy it from you for my 17x60 with a CXA that should be a CA...

      Just mill or grind some of the top surface off and reinstall the stud.
      You could even face it in the lathe with the 4 jaw.
      Maybe shim up the toolpost, and all others can still be adjusted as
      needed.

        I agree, I think I can mill it down with a carbide end mill. It's not a cheap holder and replacing it to fit is pretty pricy.
        As I don't have a lot in it I think its a good option.
        Thanks

          If it is hard, grinding it would be my first choice.
          But tradition has me thinking that facing it on the
          lathe would be cool. Set it up in the 4 jaw, and
          make the center point the screw hole for that
          height adjuster screw. It is going to be an interrupted
          cut anyhow. Get a negative rake carbide insert and go
          at it.

            Wouldn't he want to take some off of the bottom of the holder?

              It's not hitting on the bottom.

                I sure looks like it is. The top nut is not even close to touching. JR

                  Because it's clamped.

                  Dorian does some dumb stuff with their holders I swear.

                    I would make an L shaped piece with a hole that fits over the threaded stud and hangs down on the toolpost side. You could drill and tap for a setscrew out past the edge of the nut.

                    Then you could remove the height adjusting nut, slide the part on the threaded post and tighten the nut down on it. Then adjust the setscrew to set the height. You may want to use blue Loctite on the setscrew to make it adjustable, but stay where you put it.

                    It would be an easy part to make, and no alterations to the tool holder.

                      Yeah, ya don't wanna alter the toolholder. It's made in a fact-tree.

                        If the Dorian tool holders are anywhere near as hard as the Aloris ones I guarantee you'll destroy a carbide insert if you try and turn it in the lathe. That's a lot of interrupted cutting.

                        I messed up a carbide end mill trying to widen the slot on an Aloris BXA tool holder. Had to grind it.

                        Make the L bracket as suggested.

                          What about putting a spacer plate under the tool post. Maybe 1/4" thick, or so?

                            I am 100% with that. That thing is a hot mess of interrupted cuts it would get hurt.

                            I have the aloris side of these tool holders. I always considered dorian to be an equal. Good tooling.

                            The "L" bracket "soon to be Patented" was difficult to see the first few times I read it. Then I got it. Nice design. Seems like more tooling in a small space as is. For a smaller lathe I meant. Nice design. JR

                              I also thought the bottom needs to come off.
