06:21 - "Fortunately being the fabricator as well as the designer, I can be like 'eh, it's all right'" - easier to forgive when you have to forgive yourself 😄!
I would say this is very difficult balancing act.. between knowing enough to know when you can work through a mistake and saying, I should have caught that... Then there is the other side where (like the light bulb)... I found 10000 ways a light bulb doesn't work... I find myself at the edge of understanding, so the next step is either total blunder or "How did I do that?"... For people like us, it's almost always an uphill battle with no appreciation from the outsiders. Then after 5000 blunders comes the reward you could almost grasp 5000 tries ago... "I can do all things through Christ, who is my strength."
@@WmSrite-pi8ck no I meant commercial fishing. My family built in fabricated a lot of boats and a fair amount of the regular cycle of using them is repairing and modifying them. So a lot of metal fabrication is involved. I've done that since being a little kid. When you're constantly chopping up aluminum things with skill saws and drills and whatnot and rewelding them into other shapes or whatever you just get used to there being aluminum chips everywhere. They're sort of like Molly grease once you have one chip around you will never be free of them. And they have this weird nack of crimping onto your hair...
I love how advanced your projects are and how they build off easier projects. The fact that you also share your mistakes really set you apart as an educator. Great work!
@@AndrewEbling idk if that's a joke but it's probably true! Was talking to my dad yesterday about that time he was tearing down an old ass brick barbecue area out the back of one of our houses and how he let me help smash the bricks even though I couldn't actually lift the full size sledge hammer. That was 22-23 years ago (I'm 26 now). So if I can remember hitting a brick with a hammer alongside my dad from when I was 3, I'm sure these boys will remember all this in a few decades too!
In my adult life, Jeremy Fielding is my inspiration. I’m now in Electrical Engineering focusing on mechatronics in part because of your videos. I just found a 6 axis arm in the storage loft at work too. So this series is gonna help me out!
The looks and attitudes of the kids saying "The old man has lost it, lets humor him for now" is so priceless and reminiscent of my kids of many years ago. There may be better things to do than work and have a good time with your kids but very very few. You are very lucky ... but then again so are your kids
As a former project manager / salesman for a machine shop that specialized in prototyping, your comments about being nice to your fabricator hit home. So many drawings where people seemed to think they needed +/- 0.0005" on a clearance bolt hole.. I quote em and explain that the part is 5 times what it should cost because I have to send it out for grinding to hit that dimension. Then ask, "Are you suuuuuuure you need this that tight?" :p
A lot of channels don't admit their mistakes. You and your workshop are amazing. I wish I'd had something like that when I was younger. Guess I'll have to settle for watching you and being envious 😁👍.
Thank you so much for making these videos. I'm a mechanical designer and fabricator at a start-up tech. Your experiences making these parts really relate to me when I first started prototyping my robots. These mistakes and bad experiences enhance our ability to grow and become experts in our field. It's the hand on experience that separates an amateur from a pro.
Future reference - WEAR A MASK when mixing concrete. Silicosis is no joke. Cement and aggregate dust is inorganic and your body can't break it down and doesn't get cleared out easily. Signed, a dude who spent a few years in a concrete lab.
My mom got concrete in her eye on a project and we had to call 911 for the third time that year. The first two times were me splashing my eye with acetone and her side building office catching on fire. It was a fun year.
It's so cool to see your kids taking an interest in what you're building and having them help out! As someone who's mixed what feels like thousands of bags of concrete by hand I would suggest using a garden hoe next time. You can get it done with a spade shovel but a garden hoe is really much easier to push and pull the mix around with. I'm sure you can imagine how the force being applied on a blade at 90 degrees to the handle would differ from that being applied to a shovel blade which is almost parallel to the handle.
How beautiful. Thanks for showing this to us, including the hard times. What a wonder that kids can make us enjoy the most arduous tasks just with their sheer presence. All best with all my heart.
Having your kids come out after all those frustrating machining issues looked like exactly the pickup you needed 😁. If it were easy, everyone would do it. Thanks for keeping it real, I definitely empathize with the struggles in the shop sometimes. I can't believe this is the first video in this series youtube recommended to me, I'm going to have to go back and watch them all!
I love your contents because I get to see you making mistakes and correcting them as you progress. That is what separates your contents from other makers who only show the perfect results which may or may not be their first attempts.
Hi Jeremy. Greetings from Australia I really like your work. little tip re the engine crane... Instead of pumping it up try lifting the jib arm gently with the stop tap open until it is past the load height, then when it eases down shut the tap with the hook positioned. If you seals are good it will not let in air and save a lot of time. Regards... John
Person watching this with me kept asking, "Why doesn't he just buy a robotic arm? Surely you could buy one for a lot less than it takes to purchase all those tools and material." I ignored it twice, but the third time I had to explain to them that buying a robot arm (or anything) isn't cool or fun. That you don't get to learn anything that way. That you don't get to have fun on the journey of exploration. Anyone can buy a robot arm. Only a boss can make a robot arm. Thanks for letting me know there's a whole group of people out there who think like I do; who want to do challenging things because they are challenging. It's nice to know that in some spheres math and science and just knowing how to do things is still cool.
Getting close to 1/2 million subs. You deserve more. Detail n accuracy is a great gift to have. I was a residential electrician for close to 40 years. Worked on high end custom homes. Some took years to build. But doing that I learned about pride in your work, like you. Your videos are great. You are great. Thanks for sharing.
I have mixed 10,000 bags or so of portland neat cement. Was subject to inspection of mud weight. 6 gallons to 1 94 pound bag = neat cement. Pumped through trash pump and tremie pipe from bottom of annular space to surface
I've just stumbled upon your channel. Wow!!! By far you have one, if not the best channel on the internet my man. Again Wow!!! Keep your channel as is, there is sooooo much our young people can see, learn, and understand why it is soooo important to stay in school and to look into other job opportunities, as well as skills. Working not only with their hands, their minds as well. To show them if college and a desk job is not what you are filling. You enjoy working with your hands and the outdoors as well. Then there are other opportunities out there for them. Sites like yours are what is needed on the internet and people like you, who are willing to share their experiences with being creative with not only your mind, your hands as well. That a job is what you make of it. That it's not a four letter word to be looked down upon, having a job skill that involves something other than You sitting behind a computer screen all day, and inside as well, showing that the computer is and can be a useful tool for your work that has nothing to do with sitting in front of its screen all day. That it is just that, a tool, that can help with other skills that involve working with your hands as well as your mind. Again you should be one of the largest channels out here in the world of the internet. I will be turning my friends and family on to your site. May God continue to Bless you and yours.
Hi Jeremy. Couple of pointers for you. Try using a shop vac to suck up the chips when you are machining. A good shop vac will take up the chips even if they are wet. You may have to pour some coolant out of the shop vac from time to time but it is a lot better then using a brush manually. Secondly, it's probably not a good idea to be mixing concrete or any other abrasive material in the shop. The dust can get into the machines and damage the ways. I hope you cleaned the machines really well after mixing the concrete and then re-lubricated everything thoroughly. Great project so far. You are an inspiration.
Jeremy, I really appreciate that you shared the mistakes and struggles of this project. It's encouraging to all of us who seldom get things working the first time! The robot is coming along great!
Concrete is great fun :) My dad and I have been remodeling a room in the basement which involved quite a lot of it. A shovel is the best tool for mixing. And an N95 mask for the dust. You can vary the water a little bit depending on whether you need it to flow or stay where you put it. Mortar sticks even better (especially on vertical surfaces) and can get into smaller spaces, but is less durable in bulk. Generally good to have both available, though obviously not needed in your case just making a heavy mass.
Any Jarvis that needs an engine hoist to move gets a thumbs-up from me! Nice build, and thanks for including your learning moments. Also, pallet jacks for a mobile Jarvis aren't very expensive, even new.
I always love the sheer happiness that comes through in your work. Great work, keep it up, and I'm looking forward to seeing you develop the rest of Iron Man's suit!
You have to love those power outages. We had one recently while I was using my laser. I drive it from a laptop which basically has a built in UPS. The controller is powered by the USB connection to the computer. So everything was fine during the very short power outage other than the stepper motors. They had no power. The controller didn't understand that and kept on sending commands. When the power came back on, the stepper motors just picked up from where they were. Needless to day the part was ruined. It was not a great loss of material, just time invested. Keep up the great content Jeremy!!
Hi Love your work, one suggestion would be when making parts from stock alloy plate I have found that skimming both sides before machining the part will help with the plate staying flat as you release a certain amount of surface tension in the stock plate when machining one side and the plate can bow if you leave the opposite side unmachined, also you can not underestimate how rigid the base needs to be to help the accuracy of the robot Keep up the great work
It’s been neat to see you grow and advance. Congratulations and am happy for you. Remember, if it is true that, “Sometimes you win, and sometimes you learn”. That would mean there is more knowledge failure.
I liked seeing the base mounting bolts that go into the concrete are proper J bolts. Some rebar matrix would have been a good addition for a chunk that size as all the bolts won't be loaded equally or gradually if the arm is accelerating fast. Something to make it stronger is the addition of a thin layer of mortar under the baseplate during final installation to fill any voids left under the plate. Just enough to squish out of the sides is ideal. This would be the same step as torquing all 8 of the bolts to the value you have chosen with the arm in the vertical position (so the forces on the plate is centered). Awesome project! And yes, do involve your children as much as possible. Not only do they learn about tools, but they learn about you and you learn about them. That is much more valuable than the robot.
This is great content Jeremy, very enjoyable and informative. Envious that your kids are so interested in what you're doing, so beneficial for all of you. Your unique content combined with your presentation style give you a must-watch channel.
many many beginner mistakes are being made here for a guy with a CNC mill. Every operation in this video was botched. Wrong depths, feedrates, stuff you just have to double check before going into machine. Leading all the way up to assembly where motors were destroyed and entire project may as well have been restarted... must have access to a lot of free cnc machining time. We dont all have this
not giving work piece right coolant, cutters (he bought?) going to gum up. You have to move the coolant nozzles while cutting or will end up with funny surface finish also when cutter is engage and disengage with work.
I had only been machining for about 2 months when I recorded most of this. So yeah.... I would expect many mistakes from a beginner like myself. I explain this in the video just before this one. Thanks for watching, and commenting... it’s helps the video:)
@@togowack iirc he made the mill himself from a lot of free parts and shared the process for others to learn. If anyone has earned the luxury of free machine time this is probably the guy.
@@togowack the professionalism is how he makes his videos and presents himself. He explains the mistakes he learned from in serious manner. There's plenty of videos where the present says things like "huh, that's not right" and "ope ****" as they're working. That can be entertaining, but it's what would be considered an unprofessional presentation.
I have somehow missed this whole series. Your videos don't show up in my subscription feed for some reason. Bloomin youtube! I have been missing out on this amazing stuff.
Thank's for sharing - I really enjoy learning from your content - you are a great teacher! I recently saved an old 120VAC washing machine motor to do something with, inspired by your past videos. :)
"that will buff out".... from my days at the CNC milling machine i remember: when making individual parts, 60%+ of the time i spent with the calipers, verifiying the part against my drawings for meeting the tolerances and being actually straight.
You make brilliant DIY videos. Thank you for the knowledge. At 7:01 - you can put up a blower nozzle setup to blow away the chips. You might have already thought about it, if so please share pros or cons if one wants to add a air blower to blow off the chips
Jeremy, please build your own 'powerwall' or some massive UPS for your shop! You deserve better than alarm-clock-style fails due to power loss. Love the content. Cheers!
I gotta say Jarvis is soo cool and scary all at the same time!!! Those last 30 seconds of video where I guess you're testing the ACK/DEC are just frightening!!!
I’ve been waiting for this!!! Woohoo! I enjoy all of you video footage, like I haven’t found a boring or slow point yet 🤘🏻 There’s always some person that doesn’t understand awesome with giving a thumbs down on a video 🤦🏼♂️
While I'm glad Jeremy and thi9s channel have moved into very advanced projects and grown well, it has moved away from the kind of DIY projects the average person would do into things which 99% of us will never be able to do or benefit from other than in gaining some knowledge we can't much use and in entertainment value from watching. I'm subbed to too many YT channels and am slimming down- sadly this is one I'm dropping as I'm just not getting anything from it anymore. You're a great man Jeremy and the work you do in making these videos is excellent. I wish you and your viewers all the best in the future for you deserve it, but it's time for me to take my own different path. Godspeed to you, I know you'll all do well
17:18 -What are you guys doing? -We're making concrete come take a look. -Oooh that sounds fun! You can see that Jeremy is quite successful in making his kids interested in making stuff.
You know you're doing parenting right when your kids voluntarily help you. Also, I definitely relate to the pains of having failure after failure. But, it's all part of the learning process.
What an amazing engineering undertaking for a guy in his shop! I imagine when the arm is complete you will program acceleration limits related to the distance from the centre? (dynamic centre of mass essentially).
Some quick pointers. Stop using a vise, they distort the part too much. Try clamping to the table. For cutting aluminum at your speeds try using a fog buster to clear chips and provide enough coolant. For slotting, if you are having trouble with the cutter loading up, try using trochoidal milling, you can make many cam packages fake this feature with adaptive milling. When facing a part try to cut in one direction. And try to avoid loading a tool more than 85% radially. For mounting the robot to the ground, a riser/base is generally a steel tube with welded plates top and bottom, the riser is then anchored to the floor, its a bit easier than a 1000 lbs cement block and casting in some studs to bolt to. Background, industrial tool builder currently been building robotic weld lines for the automotive industry. Also have done a bunch of cnc machining, mainly aluminum.
Jeremy, you should get a glove that reaches to your elbow and put axcelerometers at the pivot points and get some motion capture from arm movement data read-in. Or you could just add some colored stickers to the glove and use OpenCV and potentially avoid the wiring/expense. at some point you know you're going to want it to do some complex sequence of movements, and this would at least allow you to get a lot of raw movement data really quickly.
Expensive mistakes can be avoided by using hand tools to assemble things instead of power tools. So many people love them because it makes them look like efficient workers.
After locating a steel fabrication shop like an ironworks who will sell you their slugs from the punch press, build a steel box with a removeable top. Fill the box with the steel slugs and bolt the cover down. If you ever have to move it you can remove the slugs and put them in buckets for transportation with the box itself.
Never in a million years did I think I would have the chance to throw you some advice. But here's my chance! Please use a cross-cut sled for cutting wood that's shorter (16:00) than the distance to the fence. It's risky doing it without, as the workpiece could twist. Keep up the good work, can't wait for the next videos...! :)
Grace under the pressure of making every mistake public, very hard to do. Great works require great attitudes and we all can learn that from you, even before we learn how to build. The sound of 80 thou, that's in permanent memory now.
Go to machine shop, get experience before taking on such a project!! Just don't stay there - become independent. Also get a job where you can observe robot arms in operations somewhat so you don't end up just making another one of whats out there already.
