      I agree. These people do a great job with what they got to work with.

        If you have trouble understanding the title, I highly suggest go visiting these countries. It'll help you understand what third world means and will greatly enhance your appreciation for where you live.

          I've been to a lot of them JR. And based on this I have to agree with RB.
          How about new neighbourhoods with genuine houses. And the sewer pipe empties into the street. Simply brilliant.

          Best is the new precision involute cutter grinder.

            I didn't see anything wrong with the phrase "third world". It isnt a place, and it isn't necessarily derogatory.

                  Check that video at about 16:12, where the guy is sharpening the form cutter by grinding on the outside of the formed shape You can see the ground areas on the cutter.

                  The way they are supposed to be sharpened is to grind on the face of each section. It would be kinda OK if he was comparing it to a template, which would mean he was changing the shape to be a different cutter number intentionally, but that's not what he seems to be doing.

                  He also does not seem to be making it into a roughing cutter, since he is not grinding it enough, and also they don't seem to use roughing cutters.

                    And take that arbor off that poor KT, lay it on the road and have a truck drive over it. It's the approved straightening procedure.

                          Im not positive that the cutter you see being ground by hand has anything to do with what was being cut in this video.

                          I say this because I saw that exact same clip of the guy sharpening the cutter in a completely different video where they were making something else. It may have also not had anything to do with the video I saw it in either.

                          I think it is just some random clip that gets “edited” into videos.

                            What I have learned from these videos is what these guys lack in safety gear, they make up for with “cheater bars” on things.

                              Could be. But it's the same guy apparently. Same shirt anyhow.......

                              There is no reason to grind like that unless you are making some other item out of the cutter. I have a bunch of gear cutters that were reground into roughers / gashers, or cutters for other shapes.

                              I did notice that later he is shown trying it in the gear that is being cut. But he only sticks it in there, and does not check for gaps etc. And he does not even clean the chips first, which are all over the place.

                              I think they DO sharpen that way. It fits the gear maybe because that cutter in use was sharpened the same way! Wild.

                              I suppose the result "could" be like making a cutter by the "disk" method that Sir John (and others) have shown. But then the wheel would have to be the exact size for that cutter number.

                              What's the odds of them doing that? You saw the arbor, and the setup that looked like it was shaking around... I don't think that was all camera shake.
