Pipe and Pie Cut Welding Machine DIY

- It is hard to get perfect welds, especially when welding pipes as you have to move 360 degrees around the tube you are welding on.
I made a support tool for my welder to bet better welds on custom exhaust pipes I am making for my motorcycle. It worked!

Lots of folk can find complicated or expensive ways to solve a problem or do a job. It needs a spark of brilliance to solve a problem simply. You showed that spark in this video. Great work and impressive welds! Thanks. Les in UK 🇬🇧
Thanks a lot 🙏 I have since this video bought a small TIG welder, you can weld much slower with it and it makes it easier to get pretty looking welds. But: it taks a lot longer time than using MIG, and very much more expensive as you use enormous amounts of gas 😝 I'll probably stick to MIG welding when possible, and I actually use this DIY positioner frequently!
Good workmanship! Thanks for sharing!!
I have a lot of pie cuts to weld as I am assembling a new custom built 2.5 inch diameter, dual exhaust for my Sunbeam Tiger ( keeping me somewhat sane through these times :) ….
Glad you liked it! 😊 Ahh, that is just a very cool car! A real classic, and I would guess quite rare? Does this small car really have a V8 😲 I suppose these welds are not going to be very visible, but perhaps you want them to look nice anyway?
With a NEMA17 stepper motor, an TMC2208 Stepper Motor Driver, a Arduino Nano, a push button latched with the welding machine trigger, you then have a semi-automatic circular welding robotic arm! Or if you feel hardcore, use a closed-loop stepper motor controller instead of TMC2208, then you have the “world most precise semi-automatic circular welding robotic arm”!😅Very impressive work and very inspiring creation!
Hmm, when I think of it - I do have a stepper motor laying around somewhere after I upgraded my 3D Printer. I also have a lot of Arduino boards. Perhaps a foot pedal for start/stop
with possibility to adjust the speed is better than wiring into the welding machine trigger. It could also be smart to go backwards to find best starting point, or to redo a weld. This is actually quite a cool idea! Added to my idea backlog now 😊 Thanks a for your feedback and your idea!!! 👍
@@kihestad thanks for reading! I was thinking maybe a latched switch could turn the crank when you trigger the welder. Although I work with MCUs, I have zero knowledge about welding. It’s quite amazing if we can see a robot welding arm!
Smart man 😎
Hello. Just discovered your channel. It looks really good what you are doing👍🏻. At one point we had to make some ufo oil lamps so we made something similar to your setup. We took an electric drill with variable speeds and it works fantastically. Hope you understand what I write. Sincerely, Lars from Denmark. 🇮🇸🇩🇰
Thanks 😊 I have used it several times and found it very useful. Using a electric drill was smart, I have thought about adding a stepper motor to it, could be a nice upgrade.
you have to lay dimes...those dont count lol. robots do this all day.
Haha 😂
For avoiding the cable to rotate you could build a rotary ground clamp, see czcams.com/video/bIkHtYWENiA/video.html , maybe adapted to your use case.
I would shorten the lever to have more control about constant turning or add a motor with a potentiometer, so you can easily adapt the rotation speed to your feeding speed.
One more sub for you, great build.
Yes, having the cable curl up made it hard to keep consistent speed. I have thought of a simpler solution than what shown on the video though, I just need to be able to rotate 2 or 3 turns. My idea was to curl up a flat braided copper wire, something like this: i.ebayimg.com/images/g/yu4AAOSwaC1f7VdH/s-l1600.jpg
I think a motor is really the only thing that would make sure to get a constant speed, that would also free up both hands so you can get event better positions. I have actually a stepper motor extra after upgrading my 3D printer, might be a new project on it's way there 😊
Thanks a lot for subbing 🤩
Yes they are what are called "WELD POSITIONERS," very expensive to purchase. Try looking in / at EBAY. "Weld Positioners," under / in "Business & Industrial." Also you may want to search youtube for DIY Weld Positioners.
You haven't reinvented the wheel, you just now discovered the wheel exists, and has been around for a VERY LONG TIME. Welcome to the 21st century.
Next thing you know, your'll discover that water is wet, and rocks are hard. I'll bet that will be a shock to your self awareness.
Thanks for the tip, will check it out! I have tried searching using all kind of keywords, but not this 🙂
Is water wet? 🤪
Ahh ok, searched for it and yes I have seen those with motor. Too expensive for my limited usage, but those are useful especially for tig welding.
@@kihestad I have seen some home-made / DIY and they used (in America "Windshield,") the rest of the world "Wind-Screen" (Brushed/DC) motor's. Seem to work very well.
I would suggest that you may not want to purchase one of the expensive one's, do look them over for all engineering ideas that you can gather, to help you design / build your own. A hint if you will, if your build mission is critical (i.e., measurements in the thousandths / mm) do build with a 4-Jaw-Chuck in mind, if not use a 3-Jaw chuck. or purchase the cheap Chinese Metal Lathe Chucks Size {6 inch / 152.4mm} in a 3- Jaw, as well as a 4-Jaw.
The 4-Jaw chuck(s) give the option of build mission critical, as well as holding ill-regular shaped parts, and still turn them in a true circle. FYI. 4-Jaw chucks are hard to use at first, but as you build your skills, you'll never look at a 3-Jaw chuck the same. Is a setup in a 3-Jaw chuck fast? ANSWER: YES! Is it close in {Measurements} tolerance as a 4-Jaw, no way.
When using a 3-Jaw, your saying {Measurements} tolerance (Approx. +/- .010" in. / 0.254mm, or more) doesn't matter, close enough, is good enough.
For the smartest person in the room, yes there are adjustable 3-Jaw chucks, but you see how he's crying about the price of a Weld Positioner, he'll need heart medication for the price of a Adjustable 3-Jaw chuck.
@@stanwooddave9758 Thanks' a lot for all your useful tips! This sounds like a really fun project!
