    Hey Mr. Pete.. thanks for the lessons. I have enjoyed learning from you.
    Best wishes from Bobby in Clayton GA.

  2. Doug Perfetti says:

    Great video!

  3. harleyghost says:

    Your a great teacher, I also liked your teaching aid and the idea of
    practicing using key stock. Thank you.

  4. Dennis Schoessow says:

    Sorry for the double post I’m a newbie.

  5. Nandopereytube says:

    So well done all your videos, very clear speech and good camera settings. I
    need to learn a lot more, thanks so much

    Hey Tubal Cain. thanks for showing this. It helps out guys like myself who
    are new to the lathe. I appreciated your taking time to make this video!

    just stumbled upon this series and i can tell ya ill be watching every one
    of them!, learning mechanical engineering in university and this is far
    superior to reading about things in a book. well done from ireland!

    Choke up on them and hold them by hand. Or you can hold them in a straight
    Armstrong lathe tool holder.

  9. cdbflynow says:

    Most useful, thanks. As always, your approach and preparation greatly add
    to raw information content. This video is a good example of the
    effectiveness of video instruction on the internet. It is hard to get
    equivalent information from a book. Your video quality is quite good – what
    kind of camera do you use?

  10. Nandopereytube says:

    We want more videos, please

  11. willysnowman says:

    Thanks for the info. I learned this a while ago and could not remember how
    to do it. This is a much better learning method than a book!

    That thing is massive :??

  13. mrsargemeister says:

    Tubalcain, Once ground what is the proper position for the bit in the tool
    holder. I know the point should be on center, but at what type of angle
    should the bit be mounted with respect to the work?

  14. mrpete222 says:

    Thanks–its a FUJI S1000. Would like to get a high def.

  15. silver760 says:

    It’s good you teach this TC,the like of you and I who make/made all our own
    tooling,people today are all relying on TCT pre formed tools or tip tools,I
    can see the the skill of making your own cutting tools being lost,if not
    kept alive.

    I have just viewed the four video’s of lathe tool grinding. This is just
    what I have been looking for in how to video’s. I will be looking at all
    you videos for sure. Thank you for helping a ole guy learn new things.

  17. John Slaby says:

    Thank You. You explained this better than any book. All angles covered and
    why those angles are important w/o any fluff!! JCS

  18. Redkrabby says:

    Hello, Thank you very much for this video! As they say…..a picture says
    more then a 1000 words! Especially for a guy hows native language is not
    English. Thank you. Marcel the Netherlands.

  19. AkGrayWolf says:

    Great job, thank you for your time and knowledge. I sure would like to see
    you make one on how to sharpen drill bits. The bit sharpening videos I have
    see so far don’t teach anything and only show that some guys can throw
    sparks.

  20. jfco61 says:

    another great video

    Thank you

  23. gohuskies583 says:

    In this case you were using a long piece of stock, but how do you hold the
    cutters wich are much shorter. DO you hold them in your hand or do you hold
    them in a fixture of some kind?

  24. ostosix says:

    the still shots at the end are really clear. A picture paints a thousand
    words. thank you.

  25. ahz123 says:

    Why is the first face ground so long? It seems as if we could take off a
    lot less metal. We’d have to compensate by adjusting our 2nd face to
    match… We are cutting with just the tip of the tool, yes?

  26. Andy X says:

    nice job

  27. BARDONICHI says:

    Great video that is a nice little jig must get off me ass and get out into
    the workshop..LOL

  28. rats arsed says:

    Very pretty bit of polishing. Love the accent, the sound of British terms
    like “radializing” the nose of your tool bit amuses me.
    On a more serious note: It hurt my ears to hear the sound of swarf chewing
    into the sliding surfaces.
    Cleanliness is next to… You will always get grit on your fixture when
    grinding, but allowing a small space for the debris to pass between the
    wheel and the edge of your fixture will help. As per USA OSHA regulations;
    ” “Work rests.” On offhand grinding machines, work rests shall be used to
    support the work. They shall be of rigid construction and designed to be
    adjustable to compensate for wheel wear. Work rests shall be kept adjusted
    closely to the wheel with a maximum opening of 1/8 inch (0.3175 cm) to
    prevent the work from being jammed between the wheel and the rest, which
    may cause wheel breakage. The work rest shall be securely clamped after
    each adjustment. The adjustment shall not be made with the wheel in motion.”
    It hurt my eyes to see your wheel wag around when you started and stopped
    the grinder.
    A newly mounted wheel needs to be dressed before use (even a brand new one
    mounted by the factory on a brand new machine).
    You will gain some space when you dress your wheel to true it up. Were you
    to use an indicator to “clock” it you will see the out of round, both on
    the periphery and to a lesser extent on the face of the wheel. I recommend
    a “star’ type dresser (rotating toothed disks) for the periphery, and a
    single point diamond for the face. The silicon carbide stone provided by
    your manufacturer is better than nothing, but next to useless. Running an
    unbalanced wheel due to run out causes vibration that will eat bearings and
    give less than satisfactory grinding performance.
    Cheers

    WOW that black thumb must have cost you buckets of swear words 🙂 – thanks
    for the video

  30. TheBrick2 says:

    Nice job. Could you post a link to the plans on homemadetool please. My
    google skills are week and I can’t find it.

  31. GalaXy808 . says:

    Oh no, I’ve been grinding wrong….. But now bec.of this video now I know
    hiw to do it correctly

  32. John Scott says:

    I hope to build that jig when I get a few more tools.

  33. Carlos Vanquish says:

    hi thanks for interesting and informative video .just one thing its a
    6mm screw and not a bolt . also you should be using only the small face
    of the grinding stone . and not be grinding on the left side of the
    grinding stone . because you are putting pressure on the left sided face
    you can course it to fracture and if breaks in the grinder when spinning
    . go up like a grenade . love life work safe

  34. orange12v says:

    Very nice jig & your charts are a good idea to but if you haven’t got them
    to hand you can still work out in your head what the tapping size is, all
    metric taps have there size on them eg 8mm (dia) X 1.25 (pitch) so what you
    do is subtract the pitch from the dia 8 – 1.25 = 6.75 works every time it
    does work with imperial to but sometimes the maths give you a headache 

  35. mindfreak001009 says:

    hi there what is the name of the grinding blade? thanks..

  36. skyrocketpuke says:

    whats your next project? have you got anything in mind

  37. skyrocketpuke says:

    check out my v8 steam engine vids!

  38. skyrocketpuke says:

    thanks I made a few mistakes along the way, but its the only way you learn,
    when are you making the ash ply cut off saw? 🙂

  39. Cosmas B says:

    Nice jig! and great machining skills!

  40. kenwood8665 says:

    Hi what website did you get the drill size fot taping?

  41. Shawn Hawkins says:

    Yeah, I didn’t notice that it was a cupped wheel. Carry on.

  42. skyrocketpuke says:

    good point shaun! i should of done a better job of the video as i wasn’t
    expecting this video to be so popular my other vids are’nt lol, regards
    chris

  43. Shawn Hawkins says:

    Everything I’ve seen or read says not to grind on the side of a wheel. Am I
    mistaken?

  44. Cosmas B says:

    jup, learning by doing! Not at all because I already have a decent cut off
    saw 😉

  45. Uri Amar says:

    nice projact

  46. skyrocketpuke says:

    the cyclone extractor sounds like a very interesting project,

  47. skyrocketpuke says:

    hi theres lots out there, just google metric thread size chart, but heres a
    good one ,”the littlemachine shop charts” search that my friend

  48. skyrocketpuke says:

    thanks, and subbed 🙂

  49. Cosmas B says:

    I’m working on a decent table saw and a cyclone dust extractor.

  50. porkycrook says:

    Hi mate, just found you when going around i have now liked and sub’d.
