Powerfeed Part 1 - Fräsvorschub Teil 1
Вставка
- Опубліковано 9 лют 2025
- I started to build a powerfeed for my new milling machine using a wiper motor. In this first episode I show the overall design and machine a sleve for the feedscrew of the machine.
I’m running through some of your older videos. Many thanks for the education.
OMG Stefan used a FLY cutter, the surprises never end
Another start to a very useful project! Looking forward to the finished result.
Stefan, I love the indicator you have on your lathe, it's got some really nice travel to it!.
A great start. I am eagerly waiting for the clutch part. Thanks for the video.
cerberus Part 2 will be the clutch - Migh be out this week :)
......another one of those projects been needing to do, thanks for the show.
Hi Stefan
I Just wanted to say I sure enjoy watching your videos, Thanks
John
imystery man Thank you!
Excellent series!
I learn so much from your videos. I especially like your way of explaining what you are doing any the why behind it. Your channel is my favorite out of all the UA-cam machinist channels I subscribe to. Keep up the excellent videos!

Great start to a new project Stefan. I have a wiper motor fitted to the power feed screwcutting drive on the lathe gives complete independence for feed speed without the horrible rattle of the change gears.
Steve Wylie I also think about adding one of those motors to my lathe for powerfeed...hate changing those gears :)
In one of your videos, you showed how you found the center of the work using the DRO. Find one edge, set to zero, find the other edge the use the built in calculator to divide by 2, then set the number to the axis. If your DRO is anything like mine, do the following. Find one edge, set to zero, find the other edge, then press the “½” button and then the axis you are using, such as, you are on the X axis, then after the ½ button, press X axis (not the X0 button). The DRO will take what ever axis you pick and divide the number in half, now just move over till you get zero and you are done. Another trick, if you want to radius a corner, set up “bolt hole pattern” and take 20 plunges about the 90 degree corner, and you now have a radius, a little scalloped, but it works. You can also make large holes this way.
The idea of using an independent motor as the Vorschub AKA power feed is extremely interesting to me. None of ny machines has power feed. But I have a large collection of electric motors swiped off discarded printers. Nice source of material, by the way.
Just one of those videos I have to watch again and again! The part is just a part but it looks awesome.
Again, very nice Stephan. Look forward to Part 2. Really envy the RF 45 clone. My mill is a swiveling vertical slide for the Myford Super Seven.

Bick1027 DE Part 2 is down to editing right now, should be out this week :)
Thanks Loads stefan, I know what Im going to be building myself very soon.Gr8 Video and as always thanks for sharing your knowledge with us aspiring ones
Hi Stefan,
Think of keeping the wiper also, that could wipe off the chips as you machine... :-))
Nice project anxious to see the rest.
Pierre
pierre beaudry At the moment I try to keep the chips ON the machine, not in the whole shop - Making lexan shields for the machine...
There will be 3 or 4 more videos, but editing takes time as you know :)
Agreed...!!! Machining is the fun part, on the bright side, today I'm supposed to pick-up a wireless microphone, this will make the movements easier in the shop while recording ;-)
Watching with great interest as I have been thinking of doing the same. One point though, I read somewhere that modern wiper motors are optimized for running in one direction only, something to do with the angle of the brushes to the commutator, and burn the brushes out if used in reverse. I hope I am wrong but it might be worth checking your motor.

Brother if you press th 1/2 button it will do it automatically for you press half the axis enter it will be done😉
"Two ton iron eating roughing machine." I'm going to add that one to my list of descriptions.
Nice start :) I need to do this to my mill. Have the motor, just need the enthusiasm XD
Mr E GoGoGo! Enough motivation?
well i looked at that end of my mill the other day... The real sticking point for me is a clutch mechanism. Thought about moving the motor assembly in and out on two spindles. But i want it to look good also :/
To centre your mill with the DRO you can also use the "1/2" button instead of using the calculator (normally press the half button and then the axis you want to halve - in this case the X button).
GrahamY1970 Thank you - Didnt realise that, the manual is not the best in the world..tested the 1/2 button, works great :D
GrahamY1970 Yes, thank you! I forgot how to do it that way. And as Stefan says, the chinglish manual just gives me a headache. So I've been using the calculator method until now.
But one thing I do remember is that (at least on my DRO) in CAL-mode, I can use the zero-button for an axis to move that number over to the calculator.
That's looking pretty good. I really want to get a power feed for my Clausing mill. I may be copying your design a little.
Mike Dittman Thank you! The clausing is about bridgeportsized isnt it? Such a wiper motor should be able to drive that table along too :)
It's much smaller so I think a wiper motor would be plenty big enough.
Mike Dittman It sure is a beautiful mill, it's about 2/3rd's the size of a Bridgeport isn't it? What would you say it's dimensional proportions are in comparison to, say a Series 1 Bridgeport Mike?
BTW, I really need your help with finishing up my backing plate for my new 3-jaw , it's just 4 countersunk holes to mount it after I skim down the register. Will you be available next week? I also want to get you some eggs and a couple of tools that I have multiples of...shoot, I will email you. Sorry Stefan I forgot where I was for second, LOL!
I love this project, and also your techniques, thanks for this series. Aloha...Chuck
fantastic design and great job machining it all. would you mind if I use your design for my personal mill?
Not at all! Thats the reason why I show this stuff :)
Stefan Gotteswinter great! I only recently found your channel. every day I watch a few more videos. learning a lot. thank you.
I saw that you calculated this on your dro to determine the heart, but I can just enter 1/2, you also have that button on it, try it, works easier I thought, greetings, Joop.
Thanks for the video. I'm not a machinist, so pardon me if this sounds like a stupid question but, would there have been anyway to modify your build as to accommodate your table lead screw so you wouldn't have had to cut it? Personally I wouldn't want to cut it.
On the DRO, cant you just push that 1/2 button to do the same thing, instead of using the calculator?
bensbenz Yes! Didnt know that until now. Thank you - I was thinking thats for lathe mode.
I need to see if the wiper motor is missing from my Dodge. That look just like it! Does it generate enough torque for a proper feed without running hot?
bcbloc02 It feels powerfull enough. Those motors are rated to a maximum current of 15A or so and when moving the table along without milling it draws about 500-1000mA, So I think it will be way powerfull.
Hi Stefan,
Your table is going to go back & forth and always end up at the same place, like a wiper blade? I think I'll try a power window motor, stop it anywhere you want it to.
Hacking up your brand new lathe already, I think you just voided your warranty.
Can't wait 4 part 2.
What is the make and model of the wiper motor?
Stefan, I enjoy your videos and always learn from you.
Can you tell me about chatter and noise while turning? In this video your lathe is making a horrible noise. Is it good practice to machine while the lathe is making a hammering noise? What causes this noise when you are making a continuous co-axial cut?
great video waiting for the clutch parts i am adapting to my 9x20 lathe i have ideas but still in the what if stage
Jerry Schram I machine the clutch parts in the next video :)
great video Stefan!.....I think there is going to be a "run" on wiper motors!.I have been looking at "rigging" my knee with a non-conventional mechanism, and think this is going to be the "ticket".....cannot wait until more! I have that exact Ditron DRO unit for my mill, but still need to get it hooked up.....how do you like it?
Jim Liechty Just gut one out of the neightbours car.. ;)
I am very happy with the DRO, everything works and the accuracity seems to be absolutely ok. The manual is a bit rough - Seems like a frenchmen translated it from chinese to english using a spanish dictionary...
Stefan Gotteswinter I was wondering why my wipers quit working. /OO\
LOL!
Any chance you could show the grind on that facing/chamfering tool in a little more detail. Thankyou.
Alistair Spence I saw that tool in one of Tom Liptons videos - He has a whole one on grinding and using it:
ua-cam.com/video/uzPIUsMtUEM/v-deo.html - The facing/chamfering/turning tool starts at 12:50
Stefan Gotteswinter Thank you sir. I'm really enjoying the videos.
Beautiful work Stefan. I was wondering I notice that you don't seem to use you feed on your lathe I was wondering why? Great work as always.
Dave Hetrick I hate changing the gears for the feed ;)
Might add a motor there too, just for powerfeeding.
Why do you use your Quick-Bedslidemovement Wheel (Bettschlittenschnellverstellung) for maschining, aren't you afaid of destroying the gears?
I dont know how your maschine is exaktly build, but I would not be sure if the realy small gears of my EBK450 would take that much force.
Best regards Christian (techam)
+Christian Gerdes-Wocken I always tend to do turning with the bedslide handwheel, I had the gearbox opened and there is not much in that can break - And if something breaks it was not strong enough anyway ;)
You should do a power feed for your lathe as well. :)
David Sussens Might happen ;)
Stefan Hi.............I can't help noticing that you like to get things spot on.......it's commendable and inspirational. I noticed in this video that you turned a diameter 25.99 mm and then turned the part around in the three jaw. I wondered....... is your three jaw spot on also?
Thank You

ian beswick I practice what some people call "bump tru chuck" . My chuck has about 2/10mm clearance on its flange. I can loosen the screws and bump it to run true in about 60 seconds using a small copper knocker and a dial indicator :)
Great video, can you say what the top speed of the wiper motor?
Al T-Wing I want to know the same thing
who makes your internal mic?
What rpm does that wiper motor max at with no load? Btw love the show and content! Keep up the awesome work!
Great vid thanks mate
hi stefan,
Can you tell me what vehicle that wiper motor came off?
many thanks
Sorry, I got that motor salvaged out of some pcb-production gear, no markings on it.
Hi mate.
I think it's slightly ironic that you just sold a fully automatic machine, to start the automation of an other machine. On your DRO, why did you not just use the halving function? Today I have been looking at a shaper, it is a very nice machine, very well maintained, and only $500. The seller had only omitted to tell me that it was the size of a Golf car, and that it weighs about 5 ton. fortunately it was only a 300Km round trip.......
Marcel.
wouldn't belt drive be MUCH better - since the vibrations from the motor and gears would transfer to the workpiece through the direct drive mechanism (?)
What kind of Quick Change Tool Post is that?
Doug Rundell A swiss made Tripan 111.
I used the same type of motor for my drill press table, when my hand crank handle broke.
Why don't you use stepper motors?
tuva600 For powerfeed steppermotors dont give you anything. They are expensive and complicated to drive.
tuva600 No benefit in using steppers, only more stuff - Needs not only a powersupply and a step-generator but also a stepper driver.
With the dc motor I can use a power supply and an off-the-shelf-pwm-speedregulator.
Just read the other post beat me to it
