      What is a dxf ? I have heard the term but this computer stuff is Greek to me.All I know is how to machine ,and build things.

        A .dxf is just a drawing file format. Specifically, 'Drawing eXchange Format' created by AutoCAD.

          Even if I had the CAD file I couldn't come close to duplicating your work.

            Lane, I ran across this drawing during a web search this morning. Is this the machine your attachments came from?



            Here's a link to the site with various Darex drawings.

              Correct . That is why i call it a home made Darex. That is a exploded view of the M5 model the m4 was the same with out the point splitter .(the attachment on the right.) The sharpening attachment on the left is what I bought fro a friend . The attachment was sold as a M3 to be put on your own grinder.

                Heres what I ended up with....I scored with my ebay Darex stuff by getting the M-3 pieces like Lane, but got a bonus by also getting the splitter .... good thing too, I'd never built that thing like lane did!

                The buddy Lanes talking about, scored the full M-5 package off ebay, along with some extra stuff that Lane was able to get from him. So, the 3 of us now have these HIGH dollar drill sharpeners and we didnt have to spent tooo much.

                  Ah.......

                  If I have that right, the thing like a flat Rugby ball stuck on the holder is the cam for the relief.........

                  And it moves the holder around the pivot to form the relief?

                  That doesn't look so bad, it's a matter of messing with the geometry a bit to get the right relief, but ever after that it would be the same always..... So long as you get the drill alignment right (which is where the Drill Quack falls down)

                    "flat rugby ball" ---Hah!!, pretty good description, and you got it figured. ----That holder is to set the bit up in the chuck (rugby ball gizmo)--- get your tip angle, (135,118*, etc) and position the tip for contact to the wheel, -- when set, you move it undisturbed to the sharpener side (left) and then to the splitter, and yes, the cam determines the relief using about a 90* twist, -- with the splitter being just a rocking motion.

                    With a skilled operator it (like Lane) it takes 30-60 seconds to do a bit (if its not damaged).... we wont talk about how long it takes ME!
