  • tool post question

    quick question (i hope) for all you virtusos out there. i have a phase II wedge type quick change post that is rated "up to 12" swing" left over from my two previous lathes. i now have a 13" sheldon wm-56-p lathe. is it really critical that i get a new tool post to make up for that 1", or is this only an issue if i am actually turning a piece that is a full 13" in diameter? any help would be appreciated.

    For my 13 x 40, I got the one that goes to 15" swing. I find that with a 1/2" or 3/8" square cutter, I am adjusting the holder near the bottom of the post.

    I think you may find that you can easily make up the difference with different size square cutters or bits/bars. I'd try that before I'd run out and buy a new one.

    The problem relates to the center height of your spindle relative to the toolpost, not the diameter of the piece you are turning.

      If it dont work I would like it

      no realy, it should work, even if you have to make a new bolt/t-nut and washer for the compound topslide.

        I think the only things you need to worry about are:

        1. Can you get the toolbit at center height.

        2. Is the toolpost rigid enough for what you're doing. Presumably larger lathe implies heavier cuts, which implies a heavier toolpost, but if you're not going to do cuts that overload your present toolpost, it's not an issue.

          Given the number of folks who recommend these quick change toolposts to
          inquirers, it would be really nice if someone posted a chart showing the
          relevant dimensions and their relations. Something like an xXA (x=A,B,C,
          etc.) can be used with lathes that have a spindle to compound (or whatever)
          measurement of z1 to z2 inches with toolbits of size .... (Is it obvious yet
          that I don't use these toolholders?)

              You can always put a space under the too post to raise it up.

                "2. Is the toolpost rigid enough for what you're doing. Presumably larger lathe implies heavier cuts, which implies a heavier toolpost, but if you're not going to do cuts that overload your present toolpost, it's not an issue."

                Lest we forget the size of tool we can put into the holder should be larger for a larger lathe for strength.

                  I would go along with this. I think the biggest issue will be getting the tool on centre hight, or it may not be. If it is putting a spacer under it will probably sort it.

                  You know how you existing one worked on the previous lathe, if you were happy with it and your going to do the same type of work and your already tooled up for that one then stick with it. IMHO

                      well thanks everybody! i think the spacer is the way to go. i have to machine a new t-slot mount anyway, so ill just make sure it is tall enough. the toolholders that come with this post go up to 1/2 inch which is plenty for the sort of work i do anyway. for those wondering if these posts are a good buy, id say definately. quick tool changes without loosing position is very convienient.

                        If anybody has an Aloris CXA that is too big for their lathe, I have a Aloris BXA in new condition loaded with tooling I would trade. Even has Aloris carbide insert holders. It is too small for my LeBlond.
