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.

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.

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!

"No blood, good chamfer." -This Old Tony

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 😁

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.

This old tony I don’t know if you read comments but I really appreciate you taking your time to share your knowledge with us

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

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!

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.

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.

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)

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!!!

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.. :)

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

14:40 "... playing jumprope with barbed wire." That is the perfect analogy for chip breaking.

That was totally a WIN. Great video editing and good humor. And the award for best CNC build videos goes to Tony :) I need more, bravo, on-cor.

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.

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 .

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.

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.....

Great video, very entertaining! I like your editing style very much :) You realy hammered out that shaft!

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

It is both HILARIOUS and INFORMATIVE to watch you vids. I have enjoyed them all!

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!

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 want a t-shirt that says "This ain't rocket surgery! - TOT"

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.

'No blood, good chamfer' made me giggle, thanks for a very informative and entertaining video.

Tony, You have the best edited machining videos on youtube. A joy to watch.

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.

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

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.

hands down, the most over-engineered marble dumper i've seen on the interwebs. nice work.

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!!!

always imagined it'd be fun to be the guy who designs and makes those physical cutaways

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!

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!

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.

Love your sense of humor

Every time you stopped the lathe to to explain stuff it just made me laugh😂

You are a great machinist thanks for teaching me new and great ideas. I really admire people like you. you make learning fun.

God the theming and overall production quality is just fantastic. Fantastic work uncle tony.

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.

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.

I love the magic a big enough hammer can obtain.

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.

Always a pleasure to watch a journeyman at his trade.

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.

so satisfying when that stepper fits perfectly with the gearbox.

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)

_"Somebody should write a Country song about it."_ What would you *_collet?_* :

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.

The very last clip was priceless and even if it never got used for anything else that in itself is a win.

Love the humor of the gasoline powered mill and the hammer lathe. LOL

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.

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.

Very enjoyable, creative, fun. You are just as good as movie maker as you are as a mechanic.

Good teacher you are! If at school will be like you teachers, I want to go to school. Thanks

BTW, I am not an engineer, simply like to think of myself mechanically inclined. And your videos help me better understand for practical use.

A couple dollar ebay electromagnet and a spring steel flexure make an excellent brake. Since the holding force of a magnet drops off extremely quickly as a function of the air gap, float the electromagnet close to the braking surface or just let it rub up against it. If you use one output of a stepper driver to run the electromagnet, a couple more dollars, the response time can be rather short since the driving voltage can be high while the current is limited to whatever the electromagnet requires. Mount the electromagnets at the largest radius that is accessible. If you are just making a dividing head, add a rotary decoder to trip the electromagnet and backlash problems can be avoided. Suitably chosen old motors make great bearings and hobby quality gear motors can be used to drive the rotation. If you operate the electromagnets at reduced currents they can be used to apply a controllable drag force which is handy to remove backlash if you want to use the setup as a 4th axis. I use the same technique to even out the torque curves when using steppers.

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!

Another excellent video. The perfect combination of explanation and humor.

love the bucket dump. great video. love the process.

That motor adaptor block looks awesome. Great video.

"It's hammer time - can't touch this!" Now I know what MC Hammer was talking about. I would love a hammer that made parts with a "tappy tap tap".

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!

That video was fantastic! Not many people show how useful a hammer can be in the shop.

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

The rag joke just before the collet, simply golden.

Your work with the hammer still amazes me, 4 years later!

Awesome! Thanks for going in further detail on the way the worm gear works.

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.

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.

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!

Love your sense of humour ! My wife doesn't comment on my laughing as I'm already talking aloud, responding to your commentary :-)

I have loved worm gears ever since I first saw one almost 20 years ago.

I am loving your creativity, knowledge, and humour, and of course your videos I am envious of your electronics skills in setting up the 4 axis. Software, drivers, motor types, power supplies, etc. Where do you come from with all those experiances? You are an amazing man!!

Love the old school impact driver. I went into an auto part store a couple years ago and asked if they had any manual impact drivers, the twenty somethings behind the counter had no idea what I was talking about. “ you know, you put it an the fastener and hit it with a hammer.”. They must have thought I was a crazy old guy who hits his dewalt 20v driver with a hammer. I do but thats not the point here.

I got one of those.used it one time about 5 years ago glad i had it .life saver.

Great and funny video. I'd mount the cylinder to apply a brake shoe radially to the edge of the disk.

I really liked how you edited this video. Starting car engine sound made me laugh. You are great in what you do.

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?

seeing that chuck stop on that interrupted cut got me to pucker up real quick. I've seen that go two ways.

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.

Machinist, comedian, and video production. Yep ladies, he's a keeper.

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).

I love your older videos like this

I just love the production value and effort you put into your videos!!

"alright, no blood, good chamfer"

Sometime back, I had reason to turn numerous square plates,, into numerous round plates. When I started to turn the first plate,, I would cringe every time a corner would contact my tooling. I made a hand cranked fixture that I could mount a plate on,,, and another fixture that was perpendicular to the plate. On the second fixture was a 4” grinder that I could slowly advance,,, via a threaded base. My left hand would slowly rotate the plate (with the crank),,, and my right hand would advance the grinder toward the plate with a ratchet. So much easier on the tooling and the lathe. Lots of grinder dust,,, so I mounted it all on a wooden bench,,, outside.

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..

a split gear with a slot milled in the gears, a spring in the slot pushing the gears in the opposite direction will keep them meshed with the drive gear and reduce the back lash to nearly zero.

Ironically I'm watching this video less than a week after I purchased nearly that exact same worm drive from a auction because I thought it was cool. Now I have to build this.

You should really be making more of these funny videos. Very well explained, and lots of good info in it! Thanks for sharing..;)

Very pleasant and informative. Nice to see others also messing up from time to time Thanks for the videos.

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!

I second the impact driver. They work really well. If you don't have one just hitting a normal screwdriver with a hammer is good enough in a lot of cases. If none of that work time to heat the area around the screw or bolt to red will definitely get it out.

finding a new channel like yours is great
