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.
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. (♫)
@@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. 😉
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!
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.
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 😁
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.. :)
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)
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 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
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.....
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.
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
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!!!
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
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 .
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.
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.
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.
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
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
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.
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)
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!
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.
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!
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!
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.
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!
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!!!
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.
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?
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.
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.
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.
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 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!!
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.
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.
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.
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'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.
