  • First dovetail cut!

    I'm working on a toolpost for the Schaublin 102 and I cut the dovetail with my Ammco shaper. First time I've done this:



    I was pretty happy with how it turned out. Initially I thought about just buying a dovetail cutter, but I decided against it and put the shaper to work. I'm glad I did. I didn't have to buy the cheap dovetail cutter that may have had questionable life in 4140 HT and it forced me to learn a few things along the way.

    Fun isn't it? One of the most fun tools to run.

        Looks like a dove's tail to me. Good job!

        Make it fit.

            MLA type toolpost - nice.
            Shaper dove tails - good fun innit? And a lovely finish.
            Now you'll have to make most details of the holders in the shaper too.
            Get rid of those 'orrible end mill marks....

              I can hear the scraping of the steel. I like the use of the scraper or shaper. JR

              The sound of it shredding metal off in layers or chips. Love that...

                Very nice, well done! +1 for shapers.

                Did you leave the clapper box in line with the toolslide, or did you set it a bit further over? If you set it a few degrees further over, the tool clears the cut face better on the return stroke.

                  Wow! Nice tool porn!

                  What about a gib?

                  Edit: Never mind, it's a tool post.

                    Good eye! It is closely based on the MLA-23 design with some changes. I scaled the design down for the Schaublin, and made the body out of 4140 HT round instead of 4140 square. The tool holders are smaller as well.

                      I did have the clapper set over, but I think it needs to go more as you suggested.

                      Shaper work is fun!

                        Very nice. Cutting a dovetail is something I haven't done yet on my milling machine. One of these days, I will get brave enough or bored enough to actually buy a cutter and try machining a dovetail.-I don't have a shaper, and have no plans on buying one, but I remember well a number of large shapers running in the manufacturing company I grew up in in the mid 1960's.--Brian
