  • Slitting saw action, drilling holes and cutting metric threads

    A fellow Finnish machinist wants some features to be machined to the parts he has made.
    First there is an aluminium thing that has a small round area to hold it. A jig is made for that workpiece to mill a notch using a slitting saw.
    The second workpiece requires traditional dividing head work where drilling is done horizontally.
    Tangential threads are made to the rim of the third and final workpiece.

    Hey Bodger
    This is the kind of bs shill post I was referring to

      I would love to "hear" what is it that is wrong on posting a link on a YT video that You have created Yourself.
      Actually, I am eagerly waiting for an opening of a discusion based on that video. If the discussion title is "This is BS", then we have to go on with that one, I suppose.

      In that video I try to present some machining practises that I have learned in my puny hobby workshop. I could probably take a bunch of screenshots and build up a thread based on those. There is material more than enough, that video is one and half hours long. However, I feel that being redundant.

      So, is there other reasons than just having a gut feeling it being incorrect to link a YT video?
      Could such linking serve as a start for discussion about the machining that video is trying to present?

        I'd be much more interested in seeing pics of the various set ups and how you approached the different tasks. Videos I'm really not super interested in.

        The shill comment was probably in reference to the view that you're posting to promote your YouTube channel, which some people dislike. Personally I don't mind whether you do or don't, as it's easy enough not to click on the link, but I do think that you and everyone else here would benefit from more engagement than just posting a video link.

          The issue I have is a few people who post links to their YouTube channel and have no other interaction with this site. It only draws people away from this site. Your response indicates you aren’t one of them. My apologies. Matt has summed it up for me better than I could.

            LOL, promoting my channel
            I don't expect it growing up anytime soon. The focus being on manual machining by an IT professional with antique equipment does not make a good Clickbait

            Actually there is one thing that can make a video being not a good media. Most of the videos out there have a supernatural tempo, trying to squeeze as much as possible in as short time as possible.This is because it is a general thought that slowly progressing videos are not that interesting and do not engage viewers that well. I disagree and as usual, I'm probably wrong. Nevertheless I will stick to my habit of making slow videos that allow some time for the viewer to think over what they see.

            Another thing that distinguishes a video from a still picture and/or textual content is the use of sound. It is alright if the person who is watching the video has good hearing and is in a situation where it is possible to use the sound. However, not all of us can hear that well and it might be impolite to turn the sound on in some environment, communal transport for example. Most YT creators neglect this and produce videos that heavily rely on audio content such as music. It is also very unusual to have decent subtitles in videos. With dcecent subtitles I don't mean the ones automatically generated by YT but ones that have been hand written, optimized and translated by a real person.

            Based on this discussion, I will embed a lot more content whenever I make a post in this forum. That's a promise I might regret

              I like Esko's (I believe this is his name) videos. He does an amazing job, especially considering he was not a professional machinist. I prefer videos as there is much more detail in them. Photos are nice, but videos show the setup, details of operation which would be laborious to show in numerous photos. Besides, who wants to eat popcorn while looking at photos. My hat is off to him for sharing his projects with his audience. I am sure it takes him many hours to produce them, for our edification and enjoyment.

                There is more than one person here and I, for one, do not see any harm in posting that video. It is totally machining in it's content.It does show how you tackled some problems - successfully I hope. And it did not go against some things I really hate about some YouTube videos; like totally vague title, no introduction, no audio description, and no clue as to what is being done or why until the very end. I do not like videos that have any of those characteristics and yours does not have any.

                I tried to watch it, but had to skip ahead many times. Just too much time on each action that went into that job. Some videos will be sped up to a faster speed so that those long sequences are shorter. Or you could just show the beginning and then cut to the end. That video should be around 5 to 10 minutes and it could be that short without sacrificing any of the real content.

                At around the half way point, I just stopped watching it altogether. I may be far from an expert machinist, but it was just too drawn out. But that's me and others may appreciate all of it.

                I do not condemn it. It is probably useful to those who are less experienced at machining than I. I am trying to get started with some videos of my own and I will probably announce them here when I begin. Others have done so in the past without being called down for it and I say such announcements are welcomed. And I hope you stay around here in the future. Don't let one or two sour apples turn you away from what is a great BB.

                And if you look REAL close at an analog signal,
                You will find that it has discrete steps.

                  I already appologised for calling him out. I thought he was one of the guys that post YT channel links and nothing else. I was mistaken and said so.

                    Apologies accepterd .... yet not probably needed

                    As long as there has been bulletin boards there has been misinterpretations of messages and their senders. This is just me thinking but this is probably because most of the message is missing. There is nothing to smell, touch, see or hear. Those must be generated at the receiver end. In Finland we have a saying: "The responsibility is delegated to the listener". I am pretty sure that almost every culture has their own version of this. The phenomenon is global.
