Around the 14 minute mark is why I love this channel for more than the humor. I hardly think about planning ahead and it’s such a difficult concept for me to grasp for some reason. But when he puts it down as “order of operations” it becomes way more clear about how I should approach things. I always equate “planning ahead” as making assumptions and performing maneuvers according to those assumptions whereas “order of operations” is more about knowing what the steps are because they don’t change and there’s a more rigid way of figuring out the right answer. It’s a small difference when I’m thinking of examples in my mind but it’s making a huge impact on my method of planning and it may help me out tremendously in life if I can keep it in mind.
In our next build we will be adding a high pressure water cutter to the table. A lot of people think that you need a high end pump for a build like this. They are wrong. For this project all you need is a correctly shaped nozzle, a high pressure garden hose and a 63.26 km high water tank that contains infinite water. I suspect getting the hose will be the hardest part of this build.
Not too often you laugh at a machine shop type video, but this one did it for me. Great job. I loved that gas engine to start the lathe & the little machinist was a very nice touch. I'm building my first CNC for home hobby & considered a forth axis. It just might be worth the time, but right now I don't know what I would use it for. It never stopped me before!
You sir are awesome too watch. At 20:44 you said I don't want to bore you. Please note those who would be bored wouldn't be watching you in the first please. "bore" away please😀. Thank you for posting. I loved the one where you made a sword for your boy. I have three and one in the way. You're not only a genius but a great dad. Thanks for sharing a little of you.
Just finished watching the CNC router series back to back... Stunning! It is great for the "muddlers" in the world (like me) to see how things should be done. Your commentary is informative, light, pleasant to listen to, and humorous. The video is easy to watch. The end machine is "to die for". Thank you so much. "Liked" all the videos... subscribed a long time ago. :o)
I'm amazed that spun in your cullet in my friends shop we were making stuff and he had the same thing happen and he screamed THIS OLD TONY and I didn't understand that is how I started watching you you've taught me/us so much thanks Tony
I'm no machinist, I just watch your vids while eating. That kind of intermittent general knowledge as long shavings being dangerous is really appreciated by laymen like myself.
I like watching these old(er) videos.. It's good to see how your style has refined and evolved overtime.. :) and the brute force approach to the face plate shaft was brilliant.. :)
My wife heard me laughing my butt off at the "spun collet country song".... I tried to explain it to her. She apparently still didn't get it.Great video!
She wasn't laughing because there was nothing to laugh about. She was imagining a Dolly & Carl Ray duet about how important it is to hold tight and not push too hard, because the world stops spinning when Chuck lets go. (♫)
Having no machinery experience and never have even stepped foot into a machine shop, I find your videos both entertaining and informative. I feel like after watching your videos I'd be able to successfully scrap my own parts someday 😁
Tony it's truly awesome watching you build most thing normal folk just go out and sell one of their organs or kids to be able to purchase, but to see that you share your toys with your lil's.. NOW that's an awesome sight!!! dad of the years up for ToT!!!
@@inawenderholm9965 -- Here ya go, kids... It's almost rush hour... Y'all take this barbed wire, plus them buckets of glass shards and rusty old razor blades, and go play in the street...
Great advice about not wanting long strings and wanting chips instead. But you didn’t explain how to avoid / change the way it’s cutting? Increase or decrease lathe speed? Change cutting tool / insert? Change feed rate on the tool? Some of us are still noobs at all this. A little more explanation next time please, truthfully less humour / editing tricks and more explanatory content would be nice for those of us trying to learn. 😉
The brass driven gear can be replaced with a new one or you can make a cam ring for the drive screw and offset it to fully engage into the driven gear to remove all backlash. Machinist here 40yrs.
When I use setscrews in any sort of channel, I use a larger dia screw that gives me the same, or slightly larger, root dia as the channel, and completely machine off the tread at the end. Sometimes because of size limitations, I’ll just cut the threads down so that I take off most of the thread so that it’s mostly smooth. Not surprised about the collet. That’s a lot of torque from that faceplate for that small collet.
Man I can't wait to see you make the brake, I watched the router build and now you're expanding to fourth axis machining. I so want to build a 5' x 12' and start a cabinet shop and this inspires me to get my ass going once I get my girlfriend over here from the Philippines. I love how you explained the thought process behind the whole plan of attack, I nearly shit myself when the plate stopped rotation while you were turning the outside diameter. Keep up the great work Tony, you make guys like us proud and motivated to step out on our own and make America great again.
+Christopher Riley Thanks Christopher -- one piece at a time, sooner or later you'll get it done. Thanks for watching and good luck with the cabinet shop!
+This Old Tony Exactly what I am finding out, as the saying goes Rome wasn't built in a day. Patience is a virtue that as machinist must possess in order to break down the process in order to determine the correct path to accomplish the task of the day.
Delightful video so very well created and edited with many unexpected turns and twists. One of the best I have seen. Thanks for sharing. It is much appreciated.
this young tony, one of your excellent video you made a spindle for 4th axis and had a r/o of a few thousand, as a retired spindle maker your problem is not the faces are out but rather the housing is not on line front bearing is not in line with rear bearing .
Michael DurlingThank you, very entertaining while being informative and educational at the same time. With many presenters I find myselfwaking up with a stiff neck and have to re watch the video to see what happened while I slept.That hammer trick was a hoot!
All I have to say is: damn, you have ALL the toys....I'm rebuilding my CNC router, ordered and obtained all the raw materials, now I have to figure out how to machine them all without a mill, lathe, or other assorted toys..... But one thing I did invest in: centering/spotting drills.....just waiting for them to arrive.....
Hi Daniel, just great trademanship and engineering!! When the piece stop in the lathe, that was an "ouch" moment😉 And building an cnc router like your inspires me to do the same. Very very well done indeed👍👍 Cheers Hermann
a what,... a 'centimeter' - finally a size in units used 'round 'ear... Lol. nice share of some workshop time.... Great interwoven humour and well shot video.... Hammer good. (that's actually an expression in some areas here). so Thankyou, for a great focused effort to show, share and enjoy a creative aspect of living.
Very entertaining. You know, when you retire from being a machinist, you can always become a humorist, like Roy Rogers. Thanks for sharing your work. Always makes me want to go out in the shop and make something.
Dull day for Tony - 3 years ago. Your quick wit and humour has brightened exponentially since - to the point that the uninitiated will be missing them over their heads - UK lunar parachutist
Great video, I'm a nubee so i like the way you explain what your doing, some guys will say the same thing 3 different ways and just talk, that gets pretty boring. Anyways i really enjoy what you do.
Very good video. A lot like making a dividing head, which I did last year. If you don't have a brake (or if your brake is loose) the dividing head will not work properly. Come to think of it, you did indeed make a dividing head, cleverly disguised as a fourth axis. Motorized even! Good work.
I'm no engineer, but I feel like a good way to handle the backlash would be to put an encoder (or 2 that are out of phase if you really want precision) directly on the shaft of the 4 axis. If you also had a brake on that same axis, then as far as I can tell backlash wouldn't be an issue.
So there have been difficulties getting stuff before covid - calming to know. Watching all your vids this seems to be one where you've made a leap - love it.
when you had the stripped torx - what I usually do is use a dremel tool with a small cutting wheel and cut a slot in it then use a big flat head screwdriver to remove it
I'm not gonna lie. the whole hammer to the raw stock confused me for about a second. that was cool. As for your haft brake, I'd make it a cam operated via air cylinder. Do you have an updated video of the air brake?
Ok, so this was my first video I watched in the shop this Saturday morning over the first cup-O-coffee... I loved it and laughed my ass off, thanks for sharing!! Definitely locked me in as a new subscriber ;o)
Thanks for talking about the way you approach each operation , it holds the most valuable information , besides knowing the tap has done 3 million holes without breaking
Soooo... beastly clever, as always. Now, I have a question I've wanted to ask you for a couple years... There seems to be a slight misalignment of the spindle axis and the axis of your tailstock. I think I've seen this any number of times when you are zoomed in on drilling or boring work. What am I talking about here....? I have noticed this at 'normal' TH-cam playback speed (which often means you are at 'fast fwd'), and today I slowed to '0.25x' playback speed, and it's extra noticeable. At t=8:08 (or is the t=488) when the center drill is coming in close to the face, it looks a wee bit off, ie. to the right of the face center, then just as it makes contact, it moves/jerks/toggles to the left, ie. toward the front of the machine. Same at 8:10 for the smaller drill bit, at 8:12 for the larger, at 8:15 for the reamer. Am I nuts? Is this an optical occlusion [sic]? budget reading glasses? weak synapses? The real question: Assuming the spindle and ways are parallel, if the various bits DO, in fact, bend a wee bit as they make contact with or enter the work, what are the implications for accuracy, precision, performance of the end product(s)? Thanks for your time.
Don't know if this helps, but at one point printer manufacturers made zero backlash by using grit on a drum and a linear, rigid item to drive back and forth...the paper. So, the grit on, say a metal strip would make minute index impressions on the metal tape..presto! Zero backlash because the grit pattern is minute.
I just finished the series. Great project, I'm sure you had a few headaches thinking it through. Good hammer trick! It's nice seeing your son in the shop.
First think I thought when I first saw this was "Backlash" I used to make Rotary Axises and sell them on eBay. I just used a 3 or 4 inch Chucks with a shaft thru alum. block. NO bearings. bronze bushings(as a quality Precision device should be) with Pulley and cog belt w 4:1 ratio to the stepper. and for a brake I use a Brass Screw on top of the Block to lock the shaft. Screw also had the 2nd purpose of oiling port to drop 1 drop of lube occasionally... Worked Great!! No Backlash!!!
Great channel man. I'm in. That was indeed a real Xmas miracle with the tap, and with your story/comedy timing. I went through about 3 M5's when I built my CNC, and there's a fourth unused one still inside the gantry, welded in. It tinkles when I rapid, just to remind me where I lost it.
Hi Dear. This is Farid Khan from Pakistan. I like ur video and also planning to make a cnc but later. backlash happens bcoz of bearings and u have 2 options to troubleshoot the backlash. 1: Place a small steel ball in end of gear shaft which attached to motor so the shaft remains locked from linear movement while spinning. 2 : Install a electro-magnet to keep rotary disc locked each time when u energized the electro-magnet... instead of using air cylinder.
Learnt about backlash the first time as a kid with Lego "making" a worm gearbox, the amount backlash was rather noticeable :) Lego is a great way to learn about such thing!
I agree with Stefan G. on the video. Also, very funny when your (I believe it was your) milling machine started up with the sound of a gasoline engine. Also, nice lathe & mill work.
What the hell is he doing with that hammer!? Ahhhhh OK, very funny! Great stuff, the enjoyment you get out of your shop time and making these videos really shines through.
For a while I've toyed with the idea of a stepper motor based dividing head, so this was very informative to me, especially the pitfalls to watch out for. Also, I get a distinct but subtle Frank Howarth vibe from your videos, and this one there is a "You suck at cooking" vibe too. Love it!
Well this taught me a new saying, DON'T try this at Work folks. Thanks Tony, watching them all again Nov 2023 with new yt acct so double the No. of thumbs up.
i would have chucked up cover plate and trimmed it down to size and built my adapter from there, but this better to watch. been binge watching your videos literally all day. lol
Not trying to tell you how to do your job or anything but you can add small pneumatic caliper/disc with light pressure to be applied towards the end of the rotation if in rapid or constant during feed rotation to apply some resistant force and if need be, edit ur C value or whatever letter it is to compensate for the amount you're short/long radially. Same thing if you're using one of those manual tilting rotary tables, even though they use a worm gear they still jerk due to backlash from time to time and either spit the part out at you or snap the endmill off, best way I found to alleviate that is tighten up the brake (cheap ass little undersize thread bolt in an oversize threaded) hole as much as possible but still be able to turn the hand wheel, and you can mill at half a snails pace at least. juuust a thought..
Great video Tony. If you wanted an idea for a simple brake for this 4th axis you might look into an electromagnetic brake off a mobility scooter. Easy as pie to actuate electronically and would just require a simple hex adaptor on the other side of your gearbox.
Re your heat sink... the optimization of fin thickness and spacing will probably surprise you. Unless you have significant forced air flow, A few widely spaced fins will outperform a lot of closely spaced fins. It's easy to find optimization software on the web. Great series!
Great Video. I also built my own 4th axis. If you want a cheap way to achieve zero backlash go to ebay and find a "Harmonic Drive Reducer" They have zero backlash and some are already fitted with servo motors. I used a 50:1 for mine so that I can engrave on Silencer Tubes. The drives are typically out of robotic arms. New they run around $2500.00 but you can pick them up for $200 - $300.
Great video, Tony (Daniel?) Besides the humor, I appreciate that you show your mistakes as often those are just as valuable to learn from (i.e. that you CAN recover from them). I also appreciate that you talked about order of operation - it's a concept that gets very little attention in most machine porn videos ;)
Great cinematography (the bigger hammer) and sound effects (gas engine starting) and your son smacking himself with his "ears" and the bleep of his words. FUNNY STUFF!
It's always fun watching you solve problems. The lack of epithets is ... disturbing. The backlash on gear boxes is why my 4th axis is going under my spoil board: so that I have the room to use 4:1 belt drive and a magnetic clutch acting as a brake, without eating up all the Z headroom. It might have 99 other problems, but backlash won't be one of them and I'll have the full Z travel, plus the radius of my 4A bed. You might be able to use a magnetic clutch brake. With careful measurement (and subsequent compensation) of the backlash, it should be precise enough for decorative stuff. Look for an old Kodak 2610 film printer, or an old film splicer. They're dirt cheap in "as-is" condition, and have at least one really nice magnetic clutch (plus dichroic filters, bullet-proof power supplies, gear motors, and other useful junk).
Aside from the improvements it needs, I will NEVER get bored of watching a part get machined, then said part automatically flips to opposite side and machining resumes!
Hmmm, your air brake idea gave me an idea for an emergency stop brake for my lathe. You know.... try to have quick hands in the event of a crash... I had been throwing around ideas on what to brake and where in the motor/gear train to instal it. The scissor style brake you drew might work. Thanks!
Late to the party, but is your tailstock chuck not concentric to your headstock? It looked like the drill bits at around 8:08 were pulled a but when they engage the material.
The way you pronounce "Chuck" ALWAYS grabs my attention. Thats my name and its strange to me to hear the video say my name so assertively. Keep up the great videos and i'll keep up being a chuckin subscriber! Thanks for sharing!!
Have you seen videos of the Phalanx CIS gun used on ships? Super high precision slewing. Large diameter bearing with two pinions and two servo motors driving it. The absence of backlash comes from the servos working against each other just enough to eliminate slop. ...or just use a harmonic drive like VinceBuild.
cool to see your progress from older videos to newer. Its like the newer ones are turned up to 11. And your editing skills have gone from good to great.
Hi, new to your channel. I was brought up in engineering although I didn't follow it for my profession. I went into biology; go figure. Anyway, just wanted to say you have my sense of humour. I shall be watching and enjoying from now on ;-) Thanks for your time. Colin
I almost fell laughing when I saw your comments “if you have a PhD in Worm Gears, skip to 8:00”! I do indeed have a PhD in Worm Gearing and this is the first time it has come in handy !!! Awesome videos - keep them coming!
Around the 14 minute mark is why I love this channel for more than the humor. I hardly think about planning ahead and it’s such a difficult concept for me to grasp for some reason. But when he puts it down as “order of operations” it becomes way more clear about how I should approach things.
I always equate “planning ahead” as making assumptions and performing maneuvers according to those assumptions whereas “order of operations” is more about knowing what the steps are because they don’t change and there’s a more rigid way of figuring out the right answer.
It’s a small difference when I’m thinking of examples in my mind but it’s making a huge impact on my method of planning and it may help me out tremendously in life if I can keep it in mind.
In our next build we will be adding a high pressure water cutter to the table. A lot of people think that you need a high end pump for a build like this. They are wrong. For this project all you need is a correctly shaped nozzle, a high pressure garden hose and a 63.26 km high water tank that contains infinite water. I suspect getting the hose will be the hardest part of this build.
Not too often you laugh at a machine shop type video, but this one did it for me. Great job. I loved that gas engine to start the lathe & the little machinist was a very nice touch.

Dear.
This is Farid Khan from Pakistan.
I like ur video and also planning to make a cnc but later.
backlash happens bcoz of bearings and u have 2 options to troubleshoot the backlash.
1: Place a small steel ball in end of gear shaft which attached to motor so the shaft remains locked from linear movement while spinning.
2 : Install a electro-magnet to keep rotary disc locked each time when u energized the electro-magnet... instead of using air cylinder.
Thanks Farid!
Minute 21:17 sec is one of the most startling and humorous events on the Internet… Nice work partner

What would you *_collet?_*

I Chamfer the info and stayed for the humor
Another excellent video. The perfect combination of explanation and humor.
Learnt about backlash the first time as a kid with Lego "making" a worm gearbox, the amount backlash was rather noticeable :)
Lego is a great way to learn about such thing!
That motor adaptor block looks awesome. Great video.
+Christian Lewis Thanks Christian! (still a scary avatar)
Good teacher you are! If at school will be like you teachers, I want to go to school. Thanks
I agree with Stefan G. on the video. Also, very funny when your (I believe it was your) milling machine started up with the sound of a gasoline engine. Also, nice lathe & mill work.
love the bucket dump. great video. love the process.
I really liked how you edited this video. Starting car engine sound made me laugh. You are great in what you do.
What the hell is he doing with that hammer!? Ahhhhh OK, very funny! Great stuff, the enjoyment you get out of your shop time and making these videos really shines through.
For a while I've toyed with the idea of a stepper motor based dividing head, so this was very informative to me, especially the pitfalls to watch out for. Also, I get a distinct but subtle Frank Howarth vibe from your videos, and this one there is a "You suck at cooking" vibe too. Love it!
Well this taught me a new saying,
DON'T try this at Work folks.
Thanks Tony, watching them all again Nov 2023 with new yt acct so double the No. of thumbs up.
i would have chucked up cover plate and trimmed it down to size and built my adapter from there, but this better to watch. been binge watching your videos literally all day. lol
Not trying to tell you how to do your job or anything but you can add small pneumatic caliper/disc with light pressure to be applied towards the end of the rotation if in rapid or constant during feed rotation to apply some resistant force and if need be, edit ur C value or whatever letter it is to compensate for the amount you're short/long radially. Same thing if you're using one of those manual tilting rotary tables, even though they use a worm gear they still jerk due to backlash from time to time and either spit the part out at you or snap the endmill off, best way I found to alleviate that is tighten up the brake (cheap ass little undersize thread bolt in an oversize threaded) hole as much as possible but still be able to turn the hand wheel, and you can mill at half a snails pace at least. juuust a thought..
i like your sense of humor ;-) plus good shots, editing and super solid and clean machining!
Great video Tony. If you wanted an idea for a simple brake for this 4th axis you might look into an electromagnetic brake off a mobility scooter. Easy as pie to actuate electronically and would just require a simple hex adaptor on the other side of your gearbox.
I love the magic a big enough hammer can obtain.
Where do you get those nice blocks of aluminum to mess around with? I would think it's expensive.
Awesome! Thanks for going in further detail on the way the worm gear works.
My pleasure, thanks for watching!
The very last clip was priceless and even if it never got used for anything else that in itself is a win.
Re your heat sink... the optimization of fin thickness and spacing will probably surprise you. Unless you have significant forced air flow, A few widely spaced fins will outperform a lot of closely spaced fins. It's easy to find optimization software on the web. Great series!
BTW, I am not an engineer, simply like to think of myself mechanically inclined. And your videos help me better understand for practical use.
tony u are brilliant i watch ur videos everytime i can keep doing it! i learn alot! thnx, greeting from argentina
Love both your mad machining skills AND your sense of humor, Earned a subscriber with this one :-)
Every time you stopped the lathe to to explain stuff it just made me laugh😂
Might you use the hammer to take out the backlash?
Great Video. I also built my own 4th axis. If you want a cheap way to achieve zero backlash go to ebay and find a "Harmonic Drive Reducer" They have zero backlash and some are already fitted with servo motors. I used a 50:1 for mine so that I can engrave on Silencer Tubes. The drives are typically out of robotic arms. New they run around $2500.00 but you can pick them up for $200 - $300.
Great video, Tony (Daniel?) Besides the humor, I appreciate that you show your mistakes as often those are just as valuable to learn from (i.e. that you CAN recover from them). I also appreciate that you talked about order of operation - it's a concept that gets very little attention in most machine porn videos ;)
so satisfying when that stepper fits perfectly with the gearbox.
I got one of those.used it one time about 5 years ago glad i had it .life saver.
Does the hammer trick also work for engraving glass?
Yes, but only toughened/heat tempered glass
Like leaded glass, they make the delicate pattern with bullets?
Yes but only once
Only if you hit it just right
@@alexscaggs8406 😆😆😆 absolutely
Haha 21:15 as a newbie having no clue what is going on... your videos are just priceless :D
I love your videos and you sense of humor you sir are awesome
Always a pleasure to watch a journeyman at his trade.
Great cinematography (the bigger hammer) and sound effects (gas engine starting) and your son smacking himself with his "ears" and the bleep of his words. FUNNY STUFF!
Very pleasant and informative. Nice to see others also messing up from time to time
Thanks for the videos.
Thank you!
It's always fun watching you solve problems. The lack of epithets is ... disturbing. The backlash on gear boxes is why my 4th axis is going under my spoil board: so that I have the room to use 4:1 belt drive and a magnetic clutch acting as a brake, without eating up all the Z headroom. It might have 99 other problems, but backlash won't be one of them and I'll have the full Z travel, plus the radius of my 4A bed. You might be able to use a magnetic clutch brake. With careful measurement (and subsequent compensation) of the backlash, it should be precise enough for decorative stuff. Look for an old Kodak 2610 film printer, or an old film splicer. They're dirt cheap in "as-is" condition, and have at least one really nice magnetic clutch (plus dichroic filters, bullet-proof power supplies, gear motors, and other useful junk).
Aside from the improvements it needs, I will NEVER get bored of watching a part get machined, then said part automatically flips to opposite side and machining resumes!
Hmmm, your air brake idea gave me an idea for an emergency stop brake for my lathe. You know.... try to have quick hands in the event of a crash... I had been throwing around ideas on what to brake and where in the motor/gear train to instal it. The scissor style brake you drew might work. Thanks!
Late to the party, but is your tailstock chuck not concentric to your headstock? It looked like the drill bits at around 8:08 were pulled a but when they engage the material.
You should really be making more of these funny videos. Very well explained, and lots of good info in it! Thanks for sharing..;)
+Erling Weiseth My pleasure, thanks for stopping in.
The way you pronounce "Chuck" ALWAYS grabs my attention. Thats my name and its strange to me to hear the video say my name so assertively. Keep up the great videos and i'll keep up being a chuckin subscriber!
Thanks for sharing!!
Have you seen videos of the Phalanx CIS gun used on ships? Super high precision slewing. Large diameter bearing with two pinions and two servo motors driving it. The absence of backlash comes from the servos working against each other just enough to eliminate slop.
...or just use a harmonic drive like VinceBuild.
cool to see your progress from older videos to newer. Its like the newer ones are turned up to 11. And your editing skills have gone from good to great.
Hi, new to your channel. I was brought up in engineering although I didn't follow it for my profession. I went into biology; go figure. Anyway, just wanted to say you have my sense of humour. I shall be watching and enjoying from now on ;-) Thanks for your time.
Colin
Thanks Colin, glad to have ya!
I have loved worm gears ever since I first saw one almost 20 years ago.
That adapter is beautiful.I like your video production style too.
I almost fell laughing when I saw your comments “if you have a PhD in Worm Gears, skip to 8:00”! I do indeed have a PhD in Worm Gearing and this is the first time it has come in handy !!! Awesome videos - keep them coming!
