Fabricating a Rotary Weld Positioner from scratch. For rotating workpieces while welding. Also for grinding parts while they're rotating, rotary plasma cutting, etc. Hope you enjoy the video. Had fun building it. Let me know if you have any questions. DIY welding positioner, fabrication, DC Motor Speed Controller, Gear-reduction motor, steel, foot-switch, multi-position, home shop, light industrial, Mig, Tig welding, plasma cutting, grinding.
I think this dude likes springs
Dagur Barkarson asked why does the footswitch take over when it's plugged in. The phone jack I used is similar to a microphone jack or a jack on the input of a guitar amp, where when you unplug the plug, a little switch contact in the jack grounds the hot lead of the jack to ground. If you buy a phone jack from a place that sells them for electric guitars, or to repair guitar amps, that's most likely the type you'll get. They do that so when you yank the cord out of a guitar amp, there won't be any hum from having an "open" connection. Within the motor speed controller there is a relay that turns the power on and off and controls the direction depending on which wire you connect to ground. The center (common) lead of the toggle switch needs to go to ground for the directional switch to work. I took that lead that came from the center common terminal of that switch and ran it to the hot terminal of the phone jack. When there is nothing plugged into that phone jack, that lead gets grounded by little switch contacts in the jack, so you can turn the motor on and off on the box. But when the phone plug is plugged into that jack, it opens up the "hot" contact that would be going to ground, and connects it to the foot switch. When you step on the footswitch, it connects it to ground. The pin at the tip of the plug is the "hot" side of the plug, and the barrel of the plug is what connects to ground. Hope that helps you out.
Bravo vous êtes un grand monsieur ❤❤❤❤❤
Holy Molly I need to make one of these for myself. Thanks for the ideas, good sir!
Thanks. Hope I gave you some good ideas.
Well done, as always. The heavy metal master at work;-) Must have taken a good long while to design, source, and put this together. Looking forward to a follow-up showing this in action.
Thanks Carsten!
Great work! Meets all the needs in one package. What does the braided ground strap tie into? Is it just grounded to the body of the machine? Or is it tied into the controller board?
Have you run this with AC high freq. TIG? I have the same motor and control and the HF makes it go full speed only.
Good work! Have you considered a latching switch for the foot controller.
Thanks! I thought about it, but figured it's pretty easy to just keep my foot planted on the foot switch while welding. It doesn't take much force to hold that pushbutton down, just let my foot rest on it.
Hello I would like to ask what motor you use can you maybe give me a link for purchase.
Hello, I wanted to ask where you took the engine from?? What is the name of the engine, how powerful is it, and where can I get one? Can you maybe give me the link to buy such a motor?
great work! can you tell me, why does the footswitch take over after its been plugged in ? i dont understand how its wired to be able to run without the switch.

@@tomsgarage6264 thank you so much, this helps a lot :D
👍🏼
Thanks! 😁
Good afternoon. What motor did you use?
I used a Bodine NPM-13D3 DC Gear Motor, 24V, 2.6A 42W IP40 4.5 Torque, 60:1 Ratio 42 RPM. Got it for $54 from Ebay, which was a great deal. The only thing weird about it was that the shaft was turned down to 7/16" diameter from the usual 1/2" diameter. Probably any gear motor with a similar RPM would do the trick. With 24V, it's easier to control the speed with a cheap DC Motor speed control, but you need a 24V power supply. Good luck.
@@tomsgarage6264 Thank you
Another mutetuber. Great. /s
I need 1
Thanks! Sorry, I just made it for fun as one-off design. Not selling them.
Let me know
Dude is that 4sale
Hello, I wanted to ask where you took the engine from?? What is the name of the engine, how powerful is it, and where can I get one? Can you maybe give me the link to buy such a motor?
I got it on Ebay, luckily for only $54.00. It's a Bodine NPM-13D3 DC Gear Motor, 24V, 2.6A, 42W, 4.5 torque, 60:1 ratio, and 42RPM. But anything in that same range of torque and RPM would work probably. It was weird that it came with a shaft that had been turned down to 7/16" diameter though from its original 1/2" diameter. So I had to make a sheet metal shim to get it to work with a 1/2" ID sprocket.
