No bandsaw, no drill press, but a TIG welder. These are some priorities... Oh, and you can just put something like tin foil or heat-resistant fabric over stuff that you want to protect from the heat. It's mostly IR radiation from the arc, so very easy to shield.
Please, when welding, use something that sucks the smoke away. Especially when welding onto nuts and bolts that *might* have a zinc coating, or another metallic coating. Steel isn't that dangerous, but when you start to oxidize coatings on nuts and bolts, a lot of terrible things come out. The discoloration on the nuts (as seen @6:28 for example) is bad news for your health.
As long as he didn't get sick he's probably fine, though avoiding inhaling zinc fumes is generally good advice. Edit: Even if he did get sick it will pass, but I've heard it's pretty unpleasant to go through.
This advice is absolutely valid and non-negotiable these days for production welding. And sound for coated materials no matter what. But for short term, occasional, hobby welding of otherwise clean material using TIG and MIG technologies in particular it's not something people ought to lose sleep over.
@@bradley3549 I previously typed a whole reply that disappeared, but there's been a lot of research on the safety and they found that even low concentrations of zinc oxide exposure can cause adverse health effects. Apparently I'm not allowed to post links here.
Haha I bet it will. Pretty sure you can't ride a bike "normally" with such a tiny wheel. Afaik the position of the pivot point in relation to the wheel as well as the contact area with the ground are factors involved in making it passively stable when riding.
@@legotechnic27 yes, that's true--the pivot point, anyway, and that's trivial to fix up. So it'll be a touch wobbly even if he added some mass to the wheel. OTOH, it does have automatic lateral adjustment to mitigate this, so it looks ok.
I don't want to backseat drive the expert, but yeah I was thinking perhaps the larger diameter should be aligned along the axis of movement who knows though, maybe it'll work fine!
@@Lizardwarrior1 yes I think it would make more sense that way. But as explored in last couple of videos driving the smaller wheels with an electric motor is harder than driving th big one.
I've recently transitioned to a wheelchair that uses passive Omni Wheels in the front and is steered by applying differential power to the two rear wheels. This is an excellent design, but it has a few glaring weak points. The tiniest ledge, even thick carpet, is too tall for the Omni Wheels to mount when swinging sideways. There are two 500 watt motors, I believe it has ample power. Most wheelchairs have difficulty with rugs, this is easily dealt with. But I live on a rather steep Hill. When I break traction even to the slightest degree, the chair consistently slides downhill at a little greater than a 45° angle with respect to the direction of movement. This is rather terrifying as it usually ends with the chair sliding into an obstacle and flipping. I'm curious if you have any ideas for this? I'm a retired mechanical engineer myself. I've often kicked around the idea of a friction plate on the Omni Wheels, have them default to freewheeling, but lock the smaller Wheels with the press of a button. Keeping weight down is very important, I don't see any reason this could not be done with simple bicycle linkages. In my case, I have use of my feet, so I'm trying to think of a model that links these friction plates to a foot pad perhaps? So if I know I need to traverse a slope, I could press the pedal to apply the friction disc and effectively convert the front wheels to traditional Wheels. But how do I go about doing so such that it does not impede the movement of the overall Wheels rotation? I suppose I can imagine a spring loaded disc that could be manipulated on or off while rotating, but I cannot imagine how one would be able to activate this feature on the fly so to speak. If I have to stop and lock hubs and stop to unlock hubs, it is not terribly useful. I need it more to be able to react dynamically to the terrain. I suppose unlocking it could take longer, but the ability to lock it up on the fly is something of a necessity. I have a decent amount of room to work with, there is no axle in front and I am rather narrow. My chair does not fold so the build could be permanent. Do you have any ideas? Or resources you suggest? Although, now that I read this over, perhaps I have tunnel vision. Maybe an emergency break like the old soap box derby cars, a length of wood that could be pivoted to dig into the ground to brake. It would have to be functional on many different types of terrain. Any ideas spring to mind? I'm fairly resourceful and have machine tools available. I know it's asking a great deal, and I would be happy to remunerate you however you see fit, but I would love to have you put in 5 minutes of thought and just give me a few jumping off points. I understand completely if you cannot. Your videos have been very helpful and have expanded my knowledge, I am already in your debt. Be well.
Okay at 4:10 you have inspired a new idea. Instead of a friction disc pressing against the small Omni Wheels, I could have a set of spoke tubes inside each Omni wheel, if they were tapered, I could make a cone shaped piece that drove in to the hub forcing the spokes to drive out of their tubes and apply friction to each one of the tiny Omni Wheels. This feels simpler to me, I need only a small Central shape to activate it. I think the most appealing part of it is that I could theoretically apply partial or differential pressure. Since the chair steers like a tank, if all of the small wheels on the Omni Wheels were firmly blocked, the chair would have to work very hard to take a turn. So, the first thing is that I don't think I need 100% immobility. Having differential actuation would be much better to conserve energy while still helping on the slopes. I suppose a simple L shape on each of the stub axles having the turn sit on the foot plate, if I made the cone on the outside, it could be pulled in and apply friction by stepping on the pedal. Having one for each of the front wheels, I think in very little time it would become non-thinking muscle memory to apply it in risky terrain. I would be thrilled for any input you have to offer
I will be investigating OnShape on the sheer weight of your recommendation. Sponsoring a Master Maker like James Bruton is pretty smart since he has ridiculous levels of credibility.
Pretty cool to see Onshape as a sponsor... I've used it professionally as a design consultant for the last 3 years, and my clients love the availability for their engineers to collaborate with me in real-time.
Your dedication to your projects is incredible. I don't know if you have any videos on this channel going over your background or what you did before TH-cam and how you learned to make all this stuff. If you don't that would be cool. We all know you are a tech robot wizard but we need the backstory !
just a thing about the geometry of the rollers - making them cylinders mean the wheel as a whole has 'bumps' at the corner of each cylinder - non constant radius. you can fix this by applying the wheel radius to the rollers to make them barrel shaped. this will make the wheel smoother and easier to deal with.
haha, It's funny you mention that about the 3-D printing music cause I noticed I had it stuck in my head the other day and was thinking, "I need to figure out what music this is so I can just pull it up on Spotify." After a minute I remembered it was your printing music and chuckled a bit. It's a good track!
As a 14-year participant of the FIRST Robotics Competition, I personally recommend AndyMark's selection of Mecanum wheels; if, on the other hand, you want to make a set from scratch, then I would recommend consulting the Chief Delphi forums for institutional knowledge from hundreds of FRC participants who have done similar things in the past. 🤖
@James if you have a drill press and your not sure why its working start by taking the top off and checking the belt if its not the belt and the motor isn't turning check that it can be turned if it can check the fuse most of them have a fuse, if that's fine or it doesn't have one with it "unplugged" check the switch with a multimeter if that's fine follow the wiring back to the motor. If the motor is turning fine it might be a starter cap those can be replaced but be very careful even a bad one can carry quite a lot of energy. if the motor is not turning or making a crunchy sound it could be a bearing or carbon brushes. In the end use your head and be careful while working on high voltage devices but you are creative and mechanically inclined enough that this should be something you can do and hey it could be a video project?
Great sponsor for the channel, it really fits with the content. Also, probably a bit late for this particular build but an ebike hub motor probably would have been a good simple drive system for this rather than an RC motor and belt reduction.
Skip the drill press and go straight to a mill/drill. I wish I would have done that when I was first building out my little machine shop. My regular drill press rarely gets used anymore.
Hey James, saw a cool project a while back for a 3d printed jig for a regular drill so you can drill a perfect 90 with a normal drill even against walls, might be worth a video!
Once again blown away by your construction and designs. I have noticed in a lot of your constructions you use multiple nuts to take up axel space. Is there a reason you don't use spacers in those situations? The could save weight in a lot of places, and are cheap and easy to make. Really just looking for your insight on your design choices on this one. Always trying to learn more from master craftsmen.
Anglegrinder? Steel? Did I accidentially got on the wrong channel? But well done anyways, Omni wheels are just cool. Overly complicated, but cool. And can I just say, that end-music is much better. I do listen/watch all of it every time.
Going to be awesome. Perhaps instead of flicking a switch though, you could detect when the speed is less than a low threshold, and engage auto-balancing then?
You can't use the 3d printing song for milling. I feel weird when I sing along now. 3d printing, 3d printing, 3d printing, I'm printing, 3D printing, I'm printing, 3D printing, I'm printing, 3D printing, I'm printing, 3D printing,
thank you for another fascinating movie. Had you thought of making omniwheels out of two seperate rings of wheels & placing them side by side offset by half a wheel. That way you could have much bigger spaces in between the wheels. I started wondering about an e-scooter with front wheel drive & an omniwheel at the back. I wish i had the resources to try these ideas out but alas i have to live in my head
I'm gonna be honest with ya here James..... .... .... .... ... ... .... ... ...

I'm not even sure it's from youtube's library or not... but I REALLY do enjoy it.... it's a nice song that reminds me of making progress but relaxing while doing so...

at 7:20 or so, the 3d-print scenes. what did you actually gain by printing the parts with 20-ish percent infill and not massive? I don't see a huge gain in lower weight or cost saving, but a massively reduced sturdyness.
In the book of Ezekiel in the Bible, there is a description of a "wheel within a wheel". Many years ago a NASA scientist came up with something like your omniwheel as a possible explanation
I already built the bike and the video comes up next Tuesday!
Can you make a GyroSphere from Jurassic World
Awesome, can't wait to see that one !
How have I been watching you this long without knowing you have a CNC router? We need a shop tour!

you should build a press attachment for your drill

A lot to love here.

That would work, wait for part 2!
@@jamesbruton looking forward to it
You could drive both wheels and get a 2WD bike :) But the little wheels need to be bigger when off road.
If you use a compression bit instead of an upcut, you'll get a better edge finish.
Slick. Jeesh you're so very clever.
That diy "starlite" material maybe could've helped protect the wheels during welding.
Unless you are on a dead smooth cleared surface those tiny wheels are going to put a lot of pressure on your forks and axle every time you hit even a small bump, they wont climb over anything much, even a small stone will cause a skateboard to chuck it's rider off the front by stopping suddenly.....
I highly recommend a chop saw or cut off saw, with carbide teeth as opposed to abrasive wheels. Evolution is a great choice of saw and saw blade.
I now have 2!

Its faster to print and does a pulley holder really need to be super sturdy?
great video. you the man. such creations.
3D Printing music! Yes.

Have you ever seen a 1967 Gyro-X car?
active mechanum wheels?
What is the 3D printing music?
Seems more intuitive to me to use the large diameter to go forward and use the small diameter to balance.
3 minutes in I couldn't figure out if I was watching James Bruton or Colin Furze!
I have more like this coming, stay tuned!
Why not build a band saw? There is a few excellent builds on you tube,
Kind of refreshing to see something built that didn't come off a 3D printer using 10 pounds of plastic.
I have slightly different content strategy now, but there's still quite a bit of 3Dprinting in part 2!
how about making a single omni wheel drone thing that can self balance so it looks like a sentient wheel robot thing
Комментарий в поддержку канала и ролика, а также труда мастера.
shame you couldn't get colin to fabricate one would have been a great colab
The mechanical stuff is pretty simple... it comes up next week.
Cool!
Does anybody else compulsively look away when the welding arc is shown?
স্যার আপনি কি ওপেন বায়োনিক রোবটিক্স এন্ড টিউটোরিয়াল করবেন
8:30 -- Does... does he not realize that bikes balance gyroscopically?
In the book of Ezekiel in the Bible, there is a description of a "wheel within a wheel". Many years ago a NASA scientist came up with something like your omniwheel as a possible explanation
Nice 🙂
Or, you could let your wheels be supported by helical concave gears to make the hub.
Please be making gizmo duck from darkwing duck
Have fun learning to drive that thing 😂
