  • A fun milling project for students

    I just put together a detailed instructional article for a milling project for students. It's a simple mechanism - the "Two Slider"




    If you're interested, please take a look:

    Wow, that is like the best instruction on making anything. Great job.

      Frank-- That's really neat--a project that does nothing. I'll put that on my list of stuff to make right after I have finished all the useful stuff I don't have time for Only trouble is I will be 80 by then and I don't know if I will be able to remember where I put the pictures or link

      I hope, however, that you don't take offense as I am only joking. It may do nothing useful but its still neat.

          In college we made turners cubes but milled them. I made 16 of them one night on the new CNC Bridgeport back in 1992. they had the college emblem on 2 sides and the letters W W C C on the other 4 sides. I made them for the graduating machine shop students.

          For guys who don't know what a turners cube or novelty cube is its a block with everything milled away so there is a center piece thats trapped inside and cant come out.

          like this only fancy on the inside.

            One of our compulsory projects in high school wood shop (they hadn't invented metal yet) was one of these, referred to as a "smoke grinder". Never seen one out of metal, very neat.

              neat rig Frank.

              Mike, is that one that you made? you didn't use the lathe to make the sphere? I'm having trouble getting how that could be made without a mill and lathe (or silver solder ).

              Here's one i made, cube inside a cube inside a cube - all lathe work. Lautard provided the intellectual umph, I provide the material and lathe ....if you don't have it, and you should, one of his beside readers gives detailed instructions

              .

                The operative word in Mike's description is "CNC". That makes it pretty straightforward to put many shapes inside the cube.

                Failing CNC, try a form tool that's capable of an undercut.

                  THANK YOU FOR THE EXCELLENT INSTRUCTIONS !! I'm going to show this to my shop teacher and see if he's interested in using it for his beginning class Great HOW-TO's with all the instructions and pictures !!

                    someone else on this site made one of those awhile back, pretty cool except he called it a bullshi7grinder or a nothing grinder,

                      Frank: My brother made one of those in wood shop when he was a kit. However unlike yours you needed to turn the crank by hand. From your video, it would appear that you have perfected peripheral motion. Gary P. Hansen

                        You sure did Frank, and a wonderful job of it !

                        I must admit though that I was drawn to the edge finder with the very noticeable and large kick off.

                        Where did you find that ?

                          Ken - thanks for the good word. I learned about that edge finder on this forum, I think. It's a Hermann Schmidt and it really does kick over nicely. I gave away my Starrett right after I tried the Schmidt the first time.

                            Great job Frank, having just purchased my first mill and just getting it set up your article could not have been more timely. Although I don't have the DRO you gave me so many good commonsense tips on clamping and centering, I may just print it out and take it to the shop with me . I may not make the gadget, but I think your techniques will get me off to a good start.
                            Many Thanks
                            James

                              Thanks for the link Frank,
                              Had to grit my teeth a bit on the price but it has been ordered, the larger kick off should be much easier to see, not that my age is effecting my eye sight

                              What rpm do you run it ?
