      Methinks a mix is good. Depends on the subject or question.
      Video length depending on content I think is a hallmark of actually understanding how to present something.
      ...I think it really means it takes as long as it takes. If he gets away with only a short video, he's fine. If it takes a long video or multiple parts, then it does. It taking as long as it takes means, uh, it takes as much as it should.

    For grinding, I recommend finding the easiest enemies to defeat who also yield the most experience. In some cases, I'll actually go for lower yield enemies who are easier to defeat so that I can multitask or watch videos while I'm levelling up. It's a matter of preference, though.

    I've been kind of thrown into the machining world out of necessity, I had theoretical knowledge in machining as a mold CAD designer but no actual cutting oil in my hands. I have my good 15 years of "experience" now, but having learned on my own what I could, I'm very grateful of the tangents in your videos... The sheer amount of learning I squeeze out of them might surprise you. Thank you This Old Theacher for them.

  • @geraldgepes
    @geraldgepes 6 років тому +10

    A video on selecting the right grit, bond, hardness and openness (I cannot remember what that's called) would go a long way in helping a lot of people. I know too many bench grinders are getting leaned on regularly because they have those concrete wheels they get shipped with on them. Any who, the coffee must be good this week man!

  • @HepauDK
    @HepauDK 6 років тому +9

    Ah, the planar grinder. Brings back memories from my apprenticeship as a fitter back in the mid-90's. One time I was tasket with making a calibration tool for a cnc machine. It didn't matter if it was 82, 81 or 80mm, it just had to be bang on. First try at 82mm, I ended up at 81.999, so I had to take off those 0.999mm.
    Another time, one of the other apprentices forgot to run the stone dry before turning the grinder off. When he started it up the following morning, the stone shattered and pieces from it flew right past the bench grinder. Luckily noone was using it or they would have ben hit in the head. Oh, and the shattered stone made dents in the magnetic table so we had to plane that too...

    • @TomHaroldArt
      @TomHaroldArt 6 років тому +5

      So to a guy who doesn't know any better, am I guessing that "running the stone dry" is done after using some kind of coolant with it, and it is done to essentially "wring out" the wheel of absorbed coolant, because if said coolant is not wrung out, it settles overnight at the lower portion of the stone, and when you fire it up, all that coolant weight creates an out-of-balance situation, which immediately goes boom? Did I get that right?

    Spent a good deal of time as a high precision grinder.
    Side wheel grinding is made easier by relieving the side of the wheel so it is slightly concave/stepped back. You want workpiece contact to be limited to a narrow band, say 3/8 inch of the side of the wheel.

      Can't say I've notice any big difference in the types of (small) parts I usually see. I started out with regular AO wheels, they worked fine, but I found the seeded gel wheels a lot more forgiving. This is a 6x12 *manual* grinder... when I start getting past 6x3 my arm gets tired and my traverse speed take a sudden nose dive. You have a general purpose wheel you like / recommend?

  • @grendelum
    @grendelum 6 років тому +2

    0:42 Funny enough I used to work with a *_polychromatic optical acoustic modulator_* or *_PCOAM..._* it was part of the laser bench at a planetarium laser show, where the main beam (50% of it, t’other half had been split off to hit fixed prisms to be split into RBGC) of white laser went through the *PCOAM* which was a crystal that vibrated at ridiculous frequencies to refract the white laser into any of 16.7M colors before it hit its XY scanner amps at the right moments so the pre-rendered laser images were the right colors in the right spots :)

  • @leeroy60

    Thanks for some very educational and humorous videos. I would like it very much if you would make a video on how I keep my lathe and mill in good condition. The are placed in a dry but cold garage and they rust. How do you maintain your machine park?

    • @nerd1000ify
      @nerd1000ify 6 років тому

      Keep the metal surfaces oiled. Cast iron and Steel will rust unless they're protected by a layer of something that's impervious to water and oxygen.

    • @Infinitesap
      @Infinitesap 6 років тому

      I sprayed them both with wd40 but still rust occured? I'm living in Denmark, where we have a tempered climate. Denmark is a very small country and everywhere is close to the see, hence the amount of salt in the air and rain is considerable.
      What oil and in what extent am I supposed to oil the surfaces. I guess that it shouldn't be totally unavailable due to lubrication?
      Thanks in advance

    • @nerd1000ify
      @nerd1000ify 6 років тому +1

      WD-40 is fairly volatile (a side effect of being thin enough to penetrate rusted bolts) and tends to evaporate over time. You might want to try a heavier oil (e.g. sewing machine oil) wiped on with a cloth. Another option might be a 'fogging oil' as is used for protecting engines in storage.

    • @Infinitesap
      @Infinitesap 6 років тому

      Thanks very much for your answer. Do you by chance have knowledge on how to get the rust removed without harming the metal shapes that are "straight"

    • @nerd1000ify
      @nerd1000ify 6 років тому

      If the rust resembles a very thin layer of fine brown powder most of it will come off when you wipe oil onto the machine. The remainder should wear off with use if you keep further corrosion at bay. If the rust is in big flakes the damage is already done- the surface beneath is probably pitted and out of shape already.
      Stubborn surface rust might be dislodged using a mild abrasive like a Scotch Brite pad or fine wet and dry sandpaper, but doing so will slightly grind the surface beneath. It's also important to make sure that you clean up afterwards, as the abrasive particles left behind will accelerate wear of the machine unless you remove them.

    yay to surface grinder video, nay to fast forward!
    There is far too few grinder videos on UA-cam, I've been watching suburbantools' videos over and over and over again.
    I've spent so many hours mesmerized in front of their videos I actually deducted this trailing edge business even though I've never even seen a grinder in real life.
    There should be a surface- and OD grinder LIVE feed, 24/7.
    Ooh, and some lapping, too!

  • @thegardenofeatin5965

    So to sum up, the wheel is dressed prior to grinding to have an OD surface parallel to the table, and then the work is ground from one edge of the wheel towards the other, and as the abrasive is worn away, the cutting edge moves along the thickness of the wheel so that the low point of the wheel and thus the deepest cut is always at the same height above the mag chuck. So grinding a sufficiently large surface might consume the entire face of the wheel and thus lose the Ultimate Flatness(tm) surface grinders are known for, but this is unlikely due to a limit in table travel, project budget or user patience.

    I always hated going to the grinder to do my rough/shave tools nobody would dress it afterwards and or leave wheels on and over tightened then the diamonds are all over the floor, coolant left on and all over the ground, holes in the walls machines left on (always 3rd shift guys) I started locking up my departments degree blocks diamond/roughing wheels since we were using carbide final shave tools just so the hundreds of people that use that surface grinder a day cant ruin them being a 24/7 plant. Having a small department was nice too, was me and 2 old dudes was awesome im 27 i learned so many techniques from them idk if i can remember them all but sure do appreciate it.

      Sándor Cseppentő Correct. Galaxy S8 in a Spigen case. Probably the most breakable phone ever made, but the case protects it very well without adding bulk. I dropped mine down the steep concrete steps at a hockey game, and it just bounced. Several times.

    Hey Tony,
    I don't know much about milling or lathing outside of what's in your videos, i just enjoy the videos. And having watched most of them, i think you might like to search for "Objects of constant width" especially here on YT. Might be a fun rainy day project that's right up your alley.
    Takecare.

    Surface grinding is for folks who like statistics and other black magic. I tried figuring a chip load per... grain in order to understand it worked? Then realized grain size, face angle and even the damn diameter of the wheel is not only probabilistic but changing at every moment you're actually grinding. 😬💥

    • @xxxyyy7252
      @xxxyyy7252 6 років тому +2

      Yes it's a form of art to some extent. It's different than drilling, turning, milling...
      Different but similar at the same time: it's a machining too. You should mind the size (dimensions) and shape (geometry) of your part, plus heat input (distortion). Many folks get it wrong, they think only about surface appearance. When it's shiny it's perfect they think. Wrong! You can screw-up geometry by improper grinding (but surface will look "nice").

  • @justtheotherdave
    @justtheotherdave 6 років тому

    Is there a reason you don't move a whole wheel width over for each pass (minus a few thou)? I think this would even the wear versus concentrating it on the leading edge - every point in the width would have an equal chance of encountering a high spot instead of "following in the footsteps" of the leading edge when taking only small "bites".
    Unrelated, but is there something like a surface grinder (maybe less precise but still pretty decent for making flat faces) for really large parts? I've got a heavy welding table that is 5 feet wide and I'd like to not hand-scrape the surface (which is cratered like the moon and couldn't be scraped flat in a lifetime).

  • @dannynimmo3052
    @dannynimmo3052 3 роки тому

    I like the grinding ones, I've been doing centerless 30-40 years, build my own grinders too, every machine I have ever run, for professional reasons anyway. Thats the part that sucks lol anyway I like to see what others have to say on that sometimes. I'm usually watching your machining videos trying to learn stuff because that,s what I suck at the most lol. I've got a decent set up to play with, I just burn up a lot of tools. I really do need to learn a little more about that, many cases I can make a part faster on a centerless faster than I can set up a lathe even with stock removal and multi diameter, I'm literally a beginner on the lathe. Your videos have been great :) Thank you for that

    I hadn't even thought about there possibly being a taper. I guess there could be, but with the precision needed to measure such a slight imperfection, the noise from the imperfections in the grinding machine become more apparent then the taper itself.
