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. SCIENCE. WORDS! AHHHH!
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.
what's this question mark non-sense, Tot? If you made a 48 part grinder series, most of the humans on this thing would watch them back to back with a blank smile on their human faces. i know i would.
I totally understand about the great variety of grinding wheels, I work in the R&D section the makes grinding wheels for a very large company. It is daunting how many there are
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.
As an automotive technician, I appreciate the heads up on things like this that I do so rarely, that I might have ended up with a chunk of grinding wheel in my head. I'm already grinding gears plenty, so this video is a welcome sight. Thanks Tony!
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! Thanks for the threepeat!
Alec, have you started doing stuff that are not made of Damascus Steel yet? I started taking a break from your channel when it exhausted everything I could think of being able to be made from Damascus Steel. Don't get me wrong, I loved your channel, just got tired of Damascus Steel. I'll be back in a flash if you've moved on.
And like that, im 95% sure I've seen every single video you have ever made. Thank you very much for these past few months of outstanding entertainment.
I used to pick up semi trailer loads at Norton in the mid 60s and over the shippers desk was a sign that read, "illegitimate non carborundum, don't let the bastards grind you down.
That was excellent. I’m doing a Materials and Manufacturing course at the moment as part of my engineering degree and this was perfect to explain a lot of what our lecturer missed.
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...
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?
I usually dont comment on videos on YT but I have to comment on a Tony video at some point. When I see a This Old Tony vid has uploaded it more or less makes my day. You are amazing keep up the good work!
I really love your videos and they tend to be a highlight of my day. I for one would not mind the videos getting longer in order for you to include everything you want. Keep up the great work!
All the different grades/grits and constructions of wheels makes for a veritable rabbit hole that will make your head spin. And how to choose which to use for what materials and such.
Man i've been wondering this since the first time I seen a machinist grinder. And you explained it perfectly, made me think of it as a broach, where 95% of the work is done by the same part of the tool and the other 5% does the finish/sizing. Therefore it last longer. Thanks TOT.
The wheel is going the right way, you have your machine facing the wrong way! Try turning it to face the wall then give it the old reach around. you'll both be glad you did!
OMG THIS IS WHAT IV ALWAYS WONDERED ABOUT A SURFACE GRINDER BUT HAVE NEVER FOUND THE ANSWER. THANK YOU FOR MAKING THIS VIDEO. NOW I CAN FINALLY SLEEP AT NIGHT!!!
I know you had to take some extra time to explain things but I learned something there. So thanks and keep up the good work. I appreciate all the hard work. I know it’s hard to translate into simple.
Short and informative for once! I didn't even think to think about grinding wheel wear, but when you mentioned it at the start of the vid i started thinking "how the heck does that get any precision? Then you explain it so even I understand, and thats without going into 20minutes of talking about why the nut seems so un-parralell... tnx
Dude. Tony. You go so far for your jokes man. I'm dying with appreciation and a collapsing set of lungs from laughter, just paused on the OPTOACOUSTIC LEVIATION device. For the homeshop. It looks really sound.
Thanks! Questions I had floating around in my mind, but since I'm likely never to have a precision grinder, not much of an urgent issue. Enjoy your videos immensely! Love the Easter Eggs.
i have though about this since the first time i saw a surface grinder. I still feel this defies all logic, while at the same time, its pretty logical that only the edge cuts.
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.
I have an S7 in an import TPU case, however I don't want to know what it feels like when you drop it :D. Also there's something wrong with the front glass, as it scratches very easily.
I've learned more from This Old Tony than I did in the first year of my engineering apprenticeship. The old guys at the place I work seem to be very protective over the niche they've got for themselves. Quite reluctant to give away too much information. Some has to be learned by accident, the rest is This Old Tony to the rescue ;)
As a basement hobby guy, and electrician by trade, this not only made me happy, but gave me some insight in the tools some may take for either black magic or granted
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 :)
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. 😬💥
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").
yay to surface grinder video, nay to fast forward! There is far too few grinder videos on RU-vid, 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!
Ahha, not that I have been kept awake at night trying to work this out, but, good explanation, and now I know this, something to file away for future reference, if I ever decide to buy a surface grinder, if I ever need to grind a surface and surely now I will forget about it and go back to my blissful ignorance on the subject.
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.
I just watched the 3 videos on fixing the grinder, and now that I rewatch this I finally get the jokes with the pt1 in title and emoji when he talks about the question everyone is asking
that was a good short video that showed some assumptions don't take the place for knowledge. I had some of the questions and assumptions never having worked with a surface grinder.
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?
I love your videos, endlessly funny and knowledge dense. I just wanted to offer: I've been a machinist only a few years, but I've spent most of that time on a surface grinder. I would love to help out, if you have any questions or need a second opinion... I'll be here, enjoying the videos.
