    Thank you to our families of soldiers, many of whom have given so much more then the rest of us for the Freedom we enjoy.

    It is true, there is nothing free about freedom, don't be so quick to give it away.

      It's all in the timing. A fixed relationship set-up between the work head and the table feed. I've done helical stuff on CNC machines but never on a manual one (with the exception of hobbing helical gers). It actualy used to be pretty common to see power take-off boxes at the end of milling machines for running dividing heads. Even saw it on This Old House one time were a guy was making new porch rail spindles on a Bridgeport for a project back in the Bob Vila days. This being for a Deckel should be top notch stuff. It's even a nice shade of green to match the envious state of my demeanor.

      PS Sears used to sell a gizmo for doing this with a router
      Forty plus years and I still have ten toes, ten fingers and both eyes. I must be doing something right.

        Kind of surprising it went so low.

          We used to do spiral flutes on a wood lathe by running a router along two angle irons mounted above the work.
          The router was controlled by a big plywood disk and a length of bowden cable [ wire rope ]
          The trick was to get the circumference to equal the distance needed to be travelled if you wanted a full twist.
          You slowly turned the big plywood disk attached to the spindle and it dragged the router along cutting the spiral flute as the spindle rotated.
          There was another cable on the back of the router going to a big weight to keep tension.

          Not a new idea I think it's been around since the 1800's althought not with routers
          Actually called Barley twist and if you use two cutters, you can cut the centre out which is called Open Bine.

            I do mine with a sharp knife !


            Seriously though I wish I could fit something like that on my old Fritz Werner, alternatively a Pittler B3 with overhead gear (I only have a small workshop).

                Alistair - It has a plate marked '5-160WS' which I guess is the model. Originally supplied by Stockwell, London.

                Good job I tidied up before taking the picture !

                            Fritz Werner

                            Alistair - No manual I'm afraid, could do with one myself, can't even figure out how to adjust the quill bearings !
                            If I ever come across one you will be the first to know.
