I just like to listen to you talk, Tony. I wish my shop teacher spoke and used humor like you do while explaining. I’d listen more in class. I’ll be a junior in high school this coming school year.
Introduce your shop teacher to the various UA-cam production houses dealing in shop work then. If they can't adopt some of the techniques in class they can at least pass along these contacts as guides for their students.
I've been an electrician for thirty years and just getting into machining as a hobby. I thought electricity was complicated but this machining stuff is much more complicated. Brain overload.
Tony Thomas Me too with being an electrician. Up until watching these videos, I thought I was pretty capable of tackling projects with a great cross section of life/work history The depth of the rabbit hole machining is overwhelming. I’d buy a new bit.
I have worked for large companies and they used to collect all worn or damaged cutting tools and send them out for re-sharpening! You are NOT a cheap skate. Enjoy your videos much more than a lot of other channels. Cheers.
@@lifuranph.d.6607 They can be regrinded to specified diameter tho, I worked on Walter cnc grinders and most of the time the customers didnt care about the end dimensions so we usually took 0.2mm or 0.3mm from the diameter and from the face we took depending on damage of the mills So for regrinding I would rather send it to some company since it was really cheap to regrind couple of mills
Now if you were to take a 4" length of .350" diameter aluminum or Delrin and poke an 'N' drill in one end about .350" deep you could then press that pencil in and get LOTS more life out of it. Turn and dress the other end to a shallow dome for added flashiness.
That's one way to do it. Or, if you are of the additive manufacturing persuasion, you can 3d-print a (hideously overengineered) pencil stump holder... :D www.dropbox.com/s/pxo2weew38wosrc/2018-10-05%2016.53.39.jpg?dl=0 +This Old Tony
I know this is an old video, but I'm trying to catch up on all the "old" subjects as I work my way through your library. And this one brought up a lot of memories of my days as an apprentice tool and due maker. Early in my training I spent a year just sharpening cutters. I learned to sharpen cutters of every shape and size, and we had all the equipment needed to sharpen them properly! Back then (mid 1980's) the injection mold industry in Grand Rapids, Michigan was just then getting into inserted fly cutters (carbide and ceramic) and things of that type, but all that new stuff was extremely expensive, so almost everything was still cut using fluted HHS and carbide cutters, which needed to be regularly sharpened. Your video bright back A LOT of memories of that for me (...and I'd just gotten over my PTSD, too)!!!
Hi ! your videos are awesome Tony. I'm a machinist myself but i did that for only about a year. I'm a small engine technician for about 10 years now and i kind of miss using a late and a milling machine. I remember a lot because of your videos. You are a very talented machinist ! keep doing this. you rock and you are so funny ! best combo.
I have been going back through your older videos and I have to say that I like the theory, or tips and tricks as you call it. I know that there are many good channels out there, but it is good to hear different peoples views and experiences. Thanks for the videos.
I've spent all day going through the archives. I can say that this is the first video of the modern This Old Tony. This is when he found his style that we've all come to love. Here's to many more years of fantastic content!
I love your videos, I can relate to your information and enjoy the way you present it. I know a little more about sharpening end-mills and someday I may get a surface grinder. Thank you for what you do!
Grinding those shapes is so complicated, I don't have the tools but manually I always struggle with the bits and simple flutes. Thanks for your videos!
Super video! Thank you Tony! 😀💪👍There is also a resource/environmental side to this. Resharpening of tools in general is a good thing. Some tools can even last a lifetime if they are well taken care of. I don't like the idea of throwing away dull quality tools containing rare earth metals just because they're dull. I like seing them sharpened😄
After watching this two times, I've decided not to invest in this jig and instead send my end mills to you for sharpening. Thanks for assuring me that this is not how I want to spend time. But great video.
Best Services There must be some poor bugger you can just send your end mills through the interwebs to fly around awhile and return to you refreshed and ready to cut through the crap that is their 9-5 job. And that person probably just watched this video and said I do this by hand all day at a bench grinder.
I personally love the more "detailed" hacks , jigs, and improvising how-to videos... Your videos are very entertaining , and make me laugh either way! Thank you for that, and all you do. Yours is one of my top three favorite channels. 🖖😎
Thanks, I have that gadget but I have no surface grinder, never tried using it but now, at least, I saw how to use it. You'd make an excellent lecturer. If I had your kind of teachers I would not have slept in classes. Bob
Just heard about your channel while watching EagleCoachShop (Dave). I like to leave comments, as you may learn, especially when asked. I love this type of video. I am not a metal worker but a wood worker. I use bits and jigs, power tools, grinders, lathes and am interested in many of the types of things you document on your channel, albeit for wood :) I've only seen a hand full of your video's but am enjoying them tremendously. Thanks for sharing , sincerely .............................
Diamond (or CBN) wheels will load up much more quickly if used dry, which they're not intended for. Such wheels should ideally be trued as soon as the motor current indicates the wheel is loading up. If this is done, the wheel will last a lot longer than if you wait until glazing can be seen, because you will only need to give it a lick. After truing, you need to dress the wheel. The resinoid material which bonds the diamond particles needs taking back below the outer profile (the cutting corners) of those particles. This is so they can penetrate the work and deliver a free cutting action. Otherwise the stone will (again) load up much more quickly. Use a dressing stick one grade finer than the wheel's grit size. This will permit the stick's abrasive grains to penetrate into the gaps between the particles on the diamond wheel, and remove the binding material.
Can you believe i actually felt the roughness of the dimond-edges of these wheels? My index-skin thinned too... Great presentator who knows how to bang the steel
Marvellous stuff all round sir! An absolute joy to watch. I can safely say that I never expected to, as it were, hear myself saying that in reference to engineering videos. A wry sense of humour you have there old bean, blended well with an informative non brain pretzel making narrative.
I have a T&C grinder (actually a universal grinder), and this is one of the things I've been anxious to learn about. Thank you for posting this, and for being so enjoyable!
+Jon Miller Ouch, you don't usually see T&C Grinder and Hobbyist Budget in the same sentence, that's a tough one. I'd suggest you pick a few things you know you'd like to grind and see which fixture(s) you'd need to cover as many of your needs as possible. Maybe start with a "universal grinding fixture" (check ebay) .. like a DoAll or clone. Maybe a Spin Indexer, too. You could get both of those (import) at a reasonable price and see how far they get you. Have fun!
This Old Tony Yeah, it's an unusual situation. Even more so since I don't have my own mill or lathe (my two brothers each got those), but that's what can happen with inheritance. I've had thoughts of selling it to buy something that will get more use, but it's way too cool of a machine to let it go. (Covel #6 if you're curious.) Thanks again!
Man, another great vid! I hate buying tools sight-unseen, so I hope you make more like this. Especially if they're all going to be this funny! That pencil was the best.
Tony, I do enjoy the detailed technical video as well. Your projects are great, but your detailed approach to explaining topics works very well. Thanks for the video. R.J.
Hey This old Tony. I love that ur reshaping ur end mills and getting more life out of them. Im a carbide sharpener and one thing i would recommend when ur sharpening carbide is to make sure it stays cool if it gets to hot itll just break. Ive had them break a few times in my face. Just a tip for you. Enjoy your day :)
I do mine carbide end mills with hand.. I use grind weel to make the face but all the others "cuts, angles etc" I make them manually. It is easy and very quick. Well, I use this process every day so, it may be easy for me. I am in die-mold businnes and the material I cut is 80% steel and stainless steel. So I can't affort to buy every day 4-5 end mills.
Like they often say, Tony, timing is everything. Thanks for an entertaining video even if it was made seven years ago. My god, have I got some binge watching to do. Regards from Canada's banana belt. 🤞🇨🇦🍌🥋🕊️🇺🇦🕊️🇺🇲👍
I have one of those end mill grinding fixtures. I got it in a box of stuff I bought at a yard sale. I had no idea how to use it, so your video was very helpful. I don't think I'd be bothered sharpening small end mills, but I have some 1/2"+ sizes, that I haven't had the heart to throw away.... cheap bastard! Who knows, if I have success with the big ones, I might actually sharpen some smaller ones! Because I'm cheap too.
Great concept for a video series. I hope this is not the last. I don't have a surface guider and I always wondered how those fixtures work. I almost want to go out and buy one before I even get a grinder. Keep drinking the prune juice and I'm sure the next subject you need to extrude will be another one I can't wait to watch.
When I regrind the front cutting edges I dont bother with secondary clearance and gashing - I just grind them with about 2...5° clearance to the center and to the back - They work very well but of course you cant plunge with them anymore. As I have a surface grinder now I might pick up that fixture too, would save me from use the single lip cutter grinder fot that purpose..
Hi Tony, how I used to dress diamond wheels was to "wear" them true by grinding a piece of steel, I was sharpening carbide cutting tools in a factory and I would sharpen so many that it would wear a dip in the surface of the wheel so I would take a square piece of steel and grind it until the wheel would wear flat again.
+Metal Tips and Tricks (Dale Derry) ha! Sorry Dale .. i suppose it was bound to happen sooner or later. Occupational hazard. :) I wouldn't let my video stop you though; as you saw it took a strange turn. I bet a standard 2 or 4 flute demo would be great. Plus, always good to see things from different perspectives.
@@andrewlockwood6102 Like a pig eatting bacon. Oh that's why people like me... I came for the show, and watched the comment's as I am re-watching Tony's shows. After 1 year, you got a "like".
Enjoyed your video, l think that you have convinced me to buy one of these fixtures. I did unsubscribe for a while because you hadn't posted any thing for a long time, it's great to see you back. I like the format and the humour. Cheers
For those of you trying to read that list of UA-cam machinist creators at about 0:13 (to see if you are on it??? I'm not.) Google Chrome has a method for stepping through a UA-cam video frame by frame. You pause the video and use the angle bracket keys "" (actually the comma and period since you don't hold down the Shift key). In this case it will disclose that the list has been repeated several times to make the fast scroll last longer. (This may change the playback speed when you resume normal play, but that can be corrected by clicking on the gear at the lower right of the playback window.) And now ... back to actually watching the video.
Enjoyed the format and learned a fair amount about the geometry and techniques. Always appreciate the way you think about things and bring it forward! Nice to start on the most complex of forms...jump in both feet. You must have gotten the Wednesday batch of those wheels. I have a smaller cup that rolls like a gyroscope at the end of its spin cycle. I'm in for anything you do to produce more vids! ~¿@ Thanks Tony! Always fun and a Pleasure! ~PJ
So, the thing is...I liked this kind of video before I saw you do this. It WAS boring in the other places I've seen this sort of thing. Your sense of humor adds exactly what it needs to be entertaining instead of just informative. I definitely would like to see more of these on your channel. Let's "face" it, their easy to do. Well...for the most part at least. As with all things, sometimes we need to "touch and go" at times. You know, not to make any milling puns or anything.
So no more builds until you get another milling stations I take it. I like the way you present the topic and it allows the viewer a little insight into what you will encounter when performing the task on the particular machine your using. Keep up the good work and hopefully you'll get another mill soon Tony.
I've got the 5C version and it works for the occasional need to do an end mill. One thing with diamond wheels on the surface grinder. Normally it is a good idea to indicate the wheel in. Wrap the OD with Scotch Tape and lightly tap the wheel to true it up with an indicator. Do not use the indicator on the diamond. Just don't how I know this. Also High Helix end mills may have less lateral forces but they have much higher end forces trying to pull them out of the collet
I once had a job running a CNC lathe at night all by myself. The day guy worked his ass off producing 93 stainless steel parts, taking no breaks nor lunch, sucking up to the boss when he came by (I know this, because he showed my how to run the machine). Best I could do was 84 and since I worked all alone I had no one to glad-hand! What to do? I figured by pushing the feed rate on the single large diameter steel drill used to remove most of the inside metal, I could make parts faster. So I doubled it. It worked, but the drill cutting edges wore out . So I rigged up a drill jig on a nearby surface grinder so I could quickly sharpen that lone drill while the CNC machine was running. Eventually, I increased the feed until I was in the realm of diminishing returns and settled on a happy medium. So for as long as that job ran, both day and night shift ran 93 parts apiece. The day guy pissed in a bottle behind the lathe and brown-bagged it, while I had plenty of time for breaks and could go to the dining area for lunch.
to square a diamond wheel for grinding carbide you need either a Norton diamond stone which they come with the wheel when you buy one from Norton that is or molly (not the drug lol) .. nice video btw
this fixture, and the 50lbs of HSS and carbide I just scored would give me a reason to fire up the WWII surface grinder thats occupied the corner of my garage since 2007.
This is the only video I could find for the use of that tool. My old surface grinder came with one and could not find info on its use thanks. found this by accident the title was of little help, I was not doing a search for poop!
Thanks a lot Tony! I was looking at those about ten years ago but it's difficult for an amatuer to purchase something like that and then be disappointed when it doesn't work
Useful video! I just snagged an old Hammond tool and cutter grinder for cheep but it needs a collet holder. Your video inspired me to get a Phase II (since I have built in angle adjustment already) and adapt it to fit. The style you have would work too. Next thing I want to try is a Spindex to sharpen flutes (I'm cheap so awaiting a few tool auctions before I give up and use Ebay) If you are gonna do more videos I'd like to see your take on that method.
+Ob Fuscated Thanks for watching Ob. I've never tried flute sharpening with the Spindex, but interesting idea. I have a 'UniGrind' I've used once or twice.. dig back through the videos you should find a flute sharpening one. In theory I imagine it'd be the same.. you'd just need to fabricate a "finger"/flute tracer to rotate the endmill while you advanced it.
I just saw this old video and thought I had a good comment for This Old Tony. Then I got to the part where I could see the grinding dust flowing off the wheel... I've never run a surface grinder with that direction of rotation.
Pretty slick. I don't have a surface grinder, nor do I need one so it's unlikely I'll end up buying one now but that was slick. I always wondered what those old guys that did "tool sharpening" actually used and I didn't really thing of a diamond impregnated grinding wheel. I may never use what I just learned but it was interesting either way. PS, I watched the "shootin the poop" vids out of order.
I just like to listen to you talk, Tony.

The depth of the rabbit hole machining is overwhelming.

Opposite way for me. 11 years as a manual/CNC machinist and now an electrical technician and tbh while at work I feel like I'm just winging it

The Lamb, No he's a tightwad lol
Yes, but then there’s no nominal size end mills after a total regrind. e.g. 1/4'' = . 2486'', 3/8'' = .3734'', etc.
@@lifuranph.d.6607 They can be regrinded to specified diameter tho, I worked on Walter cnc grinders and most of the time the customers didnt care about the end dimensions so we usually took 0.2mm or 0.3mm from the diameter and from the face we took depending on damage of the mills
So for regrinding I would rather send it to some company since it was really cheap to regrind couple of mills
thank you so much for mentioning that grinding carbide can be toxic. didn't know at all
This was both educational and entertaining. I have seen these fixtures many times but had no idea how they work. Thanks!

Now if you were to take a 4" length of .350" diameter aluminum or Delrin and poke an 'N' drill in one end about .350" deep you could then press that pencil in and get LOTS more life out of it. Turn and dress the other end to a shallow dome for added flashiness.

I know he's great, but you might want a better source for English, if you know what I mean
as always good stuff!
Hi Tony, how I used to dress diamond wheels was to "wear" them true by grinding a piece of steel, I was sharpening carbide cutting tools in a factory and I would sharpen so many that it would wear a dip in the surface of the wheel so I would take a square piece of steel and grind it until the wheel would wear flat again.
Great video. You stole my next video Idea LOL. Keep up the good work.
+Metal Tips and Tricks (Dale Derry) ha! Sorry Dale .. i suppose it was bound to happen sooner or later. Occupational hazard. :) I wouldn't let my video stop you though; as you saw it took a strange turn. I bet a standard 2 or 4 flute demo would be great. Plus, always good to see things from different perspectives.
@@ThisOldTony Ahh, perspectives. As the fly said walking up the mirror ... "that's a different way of looking at it" ...
@@andrewlockwood6102 Like a pig eatting bacon. Oh that's why people like me... I came for the show, and watched the comment's as I am re-watching Tony's shows. After 1 year, you got a "like".
@@ducewags good on ya mate! (from Australia)
Enjoyed your video, l think that you have convinced me to buy one of these fixtures. I did unsubscribe for a while because you hadn't posted any thing for a long time, it's great to see you back. I like the format and the humour. Cheers
it's good to have you back Pete.. thanks for your time!
For those of you trying to read that list of UA-cam machinist creators at about 0:13 (to see if you are on it??? I'm not.) Google Chrome has a method for stepping through a UA-cam video frame by frame. You pause the video and use the angle bracket keys "" (actually the comma and period since you don't hold down the Shift key). In this case it will disclose that the list has been repeated several times to make the fast scroll last longer. (This may change the playback speed when you resume normal play, but that can be corrected by clicking on the gear at the lower right of the playback window.)
And now ... back to actually watching the video.
I did not know that.
firefox has that too, think it is a general yt thing
it feels smooth...
16:50 While you were grinding I was thinking about the same thing!
Fantastic videos
Enjoyed the format and learned a fair amount about the geometry and techniques. Always appreciate the way you think about things and bring it forward! Nice to start on the most complex of forms...jump in both feet. You must have gotten the Wednesday batch of those wheels. I have a smaller cup that rolls like a gyroscope at the end of its spin cycle. I'm in for anything you do to produce more vids! ~¿@ Thanks Tony! Always fun and a Pleasure! ~PJ
+pjsalchemy You realize that that sort of feedback will only result in me making more videos, don't you? :)
+This Old Tony Ahhh, Yup! ~¿@
So, the thing is...I liked this kind of video before I saw you do this. It WAS boring in the other places I've seen this sort of thing. Your sense of humor adds exactly what it needs to be entertaining instead of just informative. I definitely would like to see more of these on your channel. Let's "face" it, their easy to do. Well...for the most part at least. As with all things, sometimes we need to "touch and go" at times. You know, not to make any milling puns or anything.
I definitely saw a Dalek from Dr. Who in there somewhere
So no more builds until you get another milling stations I take it. I like the way you present the topic and it allows the viewer a little insight into what you will encounter when performing the task on the particular machine your using. Keep up the good work and hopefully you'll get another mill soon Tony.
+Christopher Riley Thanks and thanks for watching!
At last the “grimey finger” test of old gets its due credit. Very useful film…
Nicely done.
+ext700 danke!
I've got the 5C version and it works for the occasional need to do an end mill. One thing with diamond wheels on the surface grinder. Normally it is a good idea to indicate the wheel in. Wrap the OD with Scotch Tape and lightly tap the wheel to true it up with an indicator. Do not use the indicator on the diamond. Just don't how I know this. Also High Helix end mills may have less lateral forces but they have much higher end forces trying to pull them out of the collet
I once had a job running a CNC lathe at night all by myself. The day guy worked his ass off producing 93 stainless steel parts, taking no breaks nor lunch, sucking up to the boss when he came by (I know this, because he showed my how to run the machine). Best I could do was 84 and since I worked all alone I had no one to glad-hand! What to do? I figured by pushing the feed rate on the single large diameter steel drill used to remove most of the inside metal, I could make parts faster. So I doubled it. It worked, but the drill cutting edges wore out . So I rigged up a drill jig on a nearby surface grinder so I could quickly sharpen that lone drill while the CNC machine was running. Eventually, I increased the feed until I was in the realm of diminishing returns and settled on a happy medium. So for as long as that job ran, both day and night shift ran 93 parts apiece. The day guy pissed in a bottle behind the lathe and brown-bagged it, while I had plenty of time for breaks and could go to the dining area for lunch.
to square a diamond wheel for grinding carbide you need either a Norton diamond stone which they come with the wheel when you buy one from Norton that is or molly (not the drug lol) .. nice video btw
this fixture, and the 50lbs of HSS and carbide I just scored would give me a reason to fire up the WWII surface grinder thats occupied the corner of my garage since 2007.
This is the only video I could find for the use of that tool. My old surface grinder came with one and could not find info on its use thanks. found this by accident the title was of little help, I was not doing a search for poop!
+Ed Ginsberg ha! sorry about that.
Thanks a lot Tony! I was looking at those about ten years ago but it's difficult for an amatuer to purchase something like that and then be disappointed when it doesn't work
the format is a success. bet you can't wait to put that new vice to work...
+Eric Skinner Just as soon as I get all that ear wax off it.
Useful video! I just snagged an old Hammond tool and cutter grinder for cheep but it needs a collet holder. Your video inspired me to get a Phase II (since I have built in angle adjustment already) and adapt it to fit. The style you have would work too.
Next thing I want to try is a Spindex to sharpen flutes (I'm cheap so awaiting a few tool auctions before I give up and use Ebay) If you are gonna do more videos I'd like to see your take on that method.
+Ob Fuscated Thanks for watching Ob. I've never tried flute sharpening with the Spindex, but interesting idea. I have a 'UniGrind' I've used once or twice.. dig back through the videos you should find a flute sharpening one. In theory I imagine it'd be the same.. you'd just need to fabricate a "finger"/flute tracer to rotate the endmill while you advanced it.
I liked the way you sharpened the end and then tested it by cutting on the side...
I just saw this old video and thought I had a good comment for This Old Tony. Then I got to the part where I could see the grinding dust flowing off the wheel... I've never run a surface grinder with that direction of rotation.
Always give the gash the attention it deserves
That fixture is perfectly capable of regrinds on 2 3. 4 flute end mills all day long. I did them for years
that pencil was a nice touch!
Most excellent! Keep up keepin' on. Thanks for sharing. (200th comment..must mean something, right?)
My brain locked at around 'pretzel'. The geometry involved reminds me of listening to a professor talk about the Fibonacci series.
Pretty slick. I don't have a surface grinder, nor do I need one so it's unlikely I'll end up buying one now but that was slick. I always wondered what those old guys that did "tool sharpening" actually used and I didn't really thing of a diamond impregnated grinding wheel. I may never use what I just learned but it was interesting either way. PS, I watched the "shootin the poop" vids out of order.
