Not only does it show all your skills & abilities it is also one of the best videos & explanations of how to overcome one's problems. I'm gona update my mill now. Thanks for the info.
Very neat work. With a coat of paint on those chip guards it would pretty much look like a manufacturers option.
I built something similar for my little antique lathe. I used a 12v car wiper motor that seems to be happy enough running at 18v (It's been running this voltage for over a year now and hasn't burnt out/caught fire yet. :) ). I didn't bother with a clutch as I can just twist it's adjuster 3 or 4 turns to slacken off and remove it's toothed drive belt. I used a wiper motor because they have 2 sets of windings in them for high and low speeds. Coupled with the PWM speed controller it gives me a brilliant feed speed range.
One idea I had, that you might find useful, was to extend the direction switches wires and run them through the "Normally closed" side of a couple microswitches. With some mounting brackets you could use them as limit switches that only break the circuit for feeding in that direction (ie, you can still reverse the feed direction and back the bed away from the triggered switch using the powered feed). In your case it would prevent any chance of running out of bed travel and stalling your motor. In my case I want to do it to help me stop trashing ceramic cutter inserts. If I'm turning a long bar at a VERY slow feed, I'm not adverse to wandering a little way away from my lathe to do something else for a couple of minutes. Sometimes I've got distracted and had to jump back to the lathe when I've heard that familiar Click click click CLACK CRUNCH" sound of lathe tool hitting chuck Jaws !!! :D
Hi Phil, I used your idea to build my powerfeed, but I made some adaptations and it worked perfectly, thanks for the idea, of all it is one of the simplest and most functional.
First class work and video , you have a talent, no none stop talking, just to the point well done.
Absolutely excellent!! Very impressive! This is some top notch quality engineuity! It looks so good and professional. The average person would without question think that was a factory component. This project is definitely something to be proud of!
It is kinda fun watching parts fly from the lathe at crazy speeds.
You are awesome. Just purchased my first small mill. Great idea. 💡 thanks
A nice solution to your problem It turned out very good, you could also add some limit switches to it as well. I might do something similar to my mill having seen your video. Thanks.
"You would think I'd learn from my mistakes... *part flies off into the workshop*"
We've all been there. More than once :)
Very nice. Probably It will be more ergonomic if you put a connecting bar under the table (if possible) to be able to engage and disengage the motor from the side of the handwheel.
awesome job, just need to add some end stops, these could be added to the directional switch circuit to cut power when it reaches the end of travel.
Agree. Another idea would be a spring that keeps the motor disengaged requiring operator input. Your suggestion is preferable while mine is a bit easier and cheaper albeit more of a pain long term.
i would put an endstopon each site configuered as an NC and then put the power on there so that if it hits the end it shuts the power down to the circuit, in the end it is just a security option, normally you standing besides it when working on it but it can happen that you are looking at something else the longer you use the feature
I was thinking the same thing. My shop bought power feed has a 2 way switch and 2 end stops. And when the switch touches one of the end stop it stops the motor.
Very nice work. I like a solution for a problem and unique as well. Brilliant.
Nice plan and execution. Inspire one of the next project. Could be perfect including two travel limit switches.
Hi, Phil... I would suggest, to add end switches or a slip clutch to the thing. I am shure, you will leave some slow / long milling tasks alone and walk away occasionally.. This is kind of a desaster waiting to happen. I tend to use this wiper motors a lot in my builds... Greets from Germany.
Nice simple design. Works really good. Remember when you parting. LOL I think we have all done that.
Cheers Fred
И не важно на каком языке мы говорим, главное что мы "технари" из одного "теста". Респект от души Бро, ты делаешь крутые вещи!!!
Artem(?) The Google Translate app on my iPhone allowed me to decipher your comment. Well said, Techie.
Very nice job! How about sprucing it up with some endstops and a connection to the emergency stop button? Crashing that mill would be a bummer.
I think the gear in the wiper motor would budge as the first one, but still!
Super clean and well done. I'll be copieing this one.
Great work and great video. If you do you to add limit switches, you would wire them NC (normally closed) between the 'outputs' of that 3-position direction switch.
Yeah I've actually added those since I made this
👏👏👏
Good design.
Just a couple of comments from an old control systems Engineer.
I assume, a bad word choice , that you turn the speed down to 0 to reverse direction. It would be useful to use an left right switch with a center position of off. This would allow the motor to be stopped then started in the other direction at the same speed setting it was going before it was stopped.
You might want to consider limit switches on the table to stop the power. You have to keep an eye on the current operation. When the table reaches its limit the motor will stall out and possibly burn up the speed controller. It is more probable the controller will go before the motor can damage the drive screw.
Excellent result Phil. I love the clutch mechanism. Nice and simple, but it works great.
Outstanding! I've been looking for guidance in making a power feed for my Benchmaster mill. This, with minor modifications, would work very well for me. Thank you for the excellent video.
Nice job!!! Very professional.
"Imma do something simple"
*whips out 3d model of entire tool*
I came here to say this
the more time you spend designing the less time you spend making it
@@rafaelguimaraes1057 Yep and less stuff goes into the scrap bin!
The return is the satisfaction gained
@@PhilVandelay no such a thing as a “scrap bin” for me. It’s called the “future useful smaller parts bin”
Very clean and impressive install!
My only note would be to add two momentary buttons witch decide the turning direction along the side of the switch, so you can move it quickly and relative accurately to spots for detail work. I find this better than small switch like that. For the machining it self switch similar to that is fine. Just find it perhaps bit small for use. Dunno maybe its just me...
What about setting safety stops? What happens when the screw runs out of threads, and jams at the end of travel?
I am going to build this. Thank you for your great video.
AWESOME!!! You could add an amp meter to show how hard the motor is working...
Outstanding
Absolutely brilliant thank you for sharing 🙂
Brilliant ! You have a very effective presentation style; your unhidden “learning opportunities” are hugely valuable to many. Great work.
The power supply was heavily vented in its original enclosure and the black one will try very hard to capture the thermal radiation portion. If you're lucky then no problem and if not they aren't expensive... anymore.
You got a subscription sir.
I thought about that too but figured since the motor is usually only running in short increments it should be fine. So far it doesn't seem to overheat (also the case is Aluminum which should help some)
@@PhilVandelay Coincidentally I thought about the intermittent nature of your usage too. I commented mainly for your audience to consider.
I'll add one more little thing about mechanic interfaces. I've found it helpful when you have alignment concerns to put all 3 in line whenever possible as in the coupling and disengagement slider pins (very nice airtight fit). This is especially true when several are being made including spares and they're all expected to be interchangeable. Just a thought from some disasters with farmed out machining.
Thanks for sharing. Always interested in automation and positioning systems of any kind.
@@PhilVandelay That style of power supply I never plan on exceeding 50% of its rated capacity. Your setup must be working at an even lower percentage. Always interested in the spec's, automation electrician, can't help it.
You did a great job on that !,
5:19 Yup, that’s a no brainer lol.
Beautiful job Sir. I need to do the same you my mill.
Sehr gut gemacht, ich werde Deine Ausführung übernehmen. Danke für die klasse Erklärung.
Good work. We featured this video in our homemade tools forum this week :)
Nice work
Thanks for this. Excellent!
That was excellent work. People like the idea of wiper motors. I made two videos of them and one of them was my most popular video.
Beautiful design and engineering. 👌👏👏😀
Nice clever solid design man......you never dissapoint.......lovin the keyway broach. Congratulations on the new place look forward to seeing it
Awesome job, but can you make it with carbon fiber, also paint it transparent, and paint your lathe blue, oh and in case nobody mentions it, add end stops.
Nice, I like that
Nice job well thought out and executed
Cheers Phil from OZ
great work! very inspiring
Very nice job!
Brilliant
Very interesting video, thank you.
Innovative design, excellent solution and great addition to the shop.
New subscriber. Thanks for sharing.
Best regards from the UK. John.
Nicely done. Should prove to be very useful. great video, thanks.
Very clever ... thanks for the idea
It is always way cooler to build something than to just buy something. I run into cash flow issues especially lately. A little over 18 months ago I was hit and run over on my 1957 Harley and money has been red;ly tight. What is POM? Is that Delrin? Also is that called a hex shaped collet block? That is fantastic. Do you have a list of items that you used. Such as the wiper motor or the PWM with all the relays?
What happens when your table reaches its end of travel? Very uncomplicated yet very efficient modification. Nice work.
I'm not sure but most likely something would break :) But I don't see why that would happen if you pay attention while working (which is mandatory with a milling machine).
Really nice work
Nice and accurate Job. i'll do The same for My milling machine. thank You for this idea
love this build phil. i have a round column mill ...this will deff be an addition...do you have any plans for sale for this by any chance...or any simple drawings..absolutely love your channel
nice job
Hi folks. If you don't have a welder you could cut a very slightly oversized square drive and use an interference fit. I've been seriously tempted to get some broaches for a while now! BobUK.
What about a limit stop ? It turned out beautifully .
Didn't make it into the video but I have added limit switches a few months ago
Very clever and well thought out design. I am definitely saving this video for a future project.
Nice work!
My 'dream' would be to have the drive motor do all the moving of the table and the handwheel simply be a forward/reverse switch with speed control. Graduations not in mm but mm/min.
this is not a clutch , its a gearbox with one gear . But indeed thanks for the inspiration :) Keep up the good work.
It is a clutch:
"A clutch is a mechanical device that allows the output shaft to be disconnected from the rotating input shaft.[1] The clutch's input shaft is typically attached to a motor, while the clutch's output shaft is connected to the mechanism that does the work."
en.wikipedia.org/wiki/Clutch
Nice and simple I like that,New Zealand
First view on this channel
A very very deep bow how you designed and created this
Really nice design and build, that was really fun to watch. Is there scope to add some push button cut-offs when the table is at max / min extension?
Yeah I have added those since, but even if it was to run into the limit, the motor isn't strong enough to really damage anything. Most likely you would just fry the controller if it stalls out for too long
Great wideo. Why you dont turn the motor 180 degree oround, it wouldn't sick out like that. And second, isn't a good idea to move the clutch relase to other side, where the wheel is? Thank's to that you could engage and disengade clutch from where the wheel is. I woudl also move electric part to the right side of machine.
planning on covering the way you dont want any chips or metal dust abrading the way ive seem mill with metal gouges half an inch deep because no one cared to clean the chips accumulating around the mill .
Yeah I have been wanting to do that, I have yet to figure out a solution that doesn't interfere with the handwheel too much on Y
Phil, You cut the two yellow wires, are those so you can control the speed? and when you push the button switch it by passes it to full speed? Again great video.

Nice
i used a wiper motor, a tumbler gear for reverse and a variable PSU from Amazon
How about steppers or even servomotors for both axis. Cnc lathe then :)
Hi Phil,
A good design and well implemented.
Take care
Paul,,
Very clean! Very handsome.
It looks all very good except you've missed the 2 most important parts - the adjustable end of travel stops.
Very well built 👍😁👍. Thanks for the explanation. I've been looking into steppers as well as these but it's difficult to know if they'll have enough torque for my needs.
Great video man, you've got my sub for sure 😊.
Cheers!
MOST people don't learn from their own mistakes, and virtually never learn from the mistakes of others.
Nice video.
Phil
Beautifully manufactured, simplicity graces. I'm interested in the control box you used. Is it possible to provide a link to it?
16:48 I'd have overlapped them the other way. As they are, chips moving towards the guards could get under the second one.
Another possibility is using a 12 point socket for finer resolution, great job tho
Damn, that's a great idea. Wish I'd have thought of that beforehand 😅
What an excellent video. It's so useful to hear your thinking as you design it. Really excellent.
Very professional looking setup, sure beats some of the power feeds that come from china!
Nicely done! If you add another power feed to one of the other axis, check out the motors that are used to move electric seats. They cost about $12 to $15 USD and are very similar to the wind shield wiper motors. I think I'm going to be adapting some of your ideas to my mill, Thanks.
Outstanding. Rapids and all, well done sir.
Nice Job! That was funny - "I have no excuse for this one..." What was the plastic material you made the bushing from?
POM, a pretty common plastic for machining. It's sturdier than one might think and a dream to machine
You should really, really put endstop detection switches to deactivate the power feed
Why? If he's using the power feed he'll be standing there. Just like power feed on a lathe.
I mean, safety features are hardly ever a bad idea
It would definitely be a bit safer but I don't think it's strictly necessary. As Daniel mentioned below, the powerfeed on the lathe is much more dangerous and they often don't have a stop switch at all, you just gotta watch what you're doing. Mine actually has a slip clutch with a stopping clamp on the bedway but like most people I never use it. The trick is to just pay attention and not let it crash into anything. With the way this is built, I think the worst thing that might happen if I run into the end of travel is that the motor would stall out, but I don't think it has enough torque to destroy the clutch parts. Of course if you crash into a work piece that's a different story, but again, same thing on the lathe, you just keep your hand on the feed switch and pay attention and try not to crash it. Besides, I will be using this mostly for facing and other operations where you can feed all the way through the part on the X axis.
Are you the thumbs down?
@@PhilVandelay Simple limit switch idea; maybe just have them between the power supply and the motor so the signal is cut if it gets hit
Cool work! But no end stop switch?
amazing bro
Hey Phil, fantastic mod! I intend to mimic your design and have already received my parts. I noticed that you modified the motor prior to your video, at least it appears you have compared to the one I have. Did you custom fab a cover plate and bypass the existing wiring harness? If so, I'd greatly appreciate any additional video or tutorial on this. Again, well done. Thanks!
Better to index on the flats of your collet block rather than the edges.
Beautifully explained and demonstrated, and such a simple great idea ............... I take it a windscreen wiper motor has quite a lot of torque then, as that looks to be quite a heavy milling table.
I just wish you had supplied the links for the eBay parts you bought.
Thank you so much for showing us this, it gives me a few ideas ................... a 'sheet steel trimmer' I have been working on, just couldn't find the right motor to use. I also take it that the motor is geared. Can anybody confirm this please ?

Phil, is your workshop in a shared area as you can hear people talking/working in the back ground?
It used to be, yes
Hey Phil, Great work! can you share the 3D model of the SX4?
But you need a stopper sensor now.... to protect it from go beyond the maximum range
Phil,great build which works very well. Is there any chance of you posting some links to the component shopping list to make it easier for others to copy your build?
Now you just need to mod in some stops.
Did you add limit switches so the motor can turn off once it hits the limit?
Your skill level is outstanding. Both for ‘visualizing’ the problem and then imagining how to put it all together. If you don’t mind my asking, was your training formal and how many years? Also, what kind of mill and lathe do you own. I’m in the market. Weekend warrior type with no formal training, just interested in learning and doing. Thanks Phil
Hey thanks. I'm actually self taught in all of this, but have been tinkering/building ever since I was a kid in various ways so I guess the experience kind of adds up/translates to different things. I've only really been machining for 2-3 years or so. My Mill and Lathe are both from a company called "Sieg", models are SC-10 and SX-4. They're chinese machines somewhere between high-end hobbyist and entrly-level professional I'd say, as you can see in my videos you can do some serious work on them without spending a fortune or taking up a huge amount of space. There's always a few minor annoyances with these types of machines, but overall I'm very happy with them. If you're looking for mills you might also look at the very popular RF-45, a similar chinese design that is being sold under a ton of different brands all over the world. Generally I think these machines are better than their reputation. If you haven't, check out Stefan Gotteswinter on RUclips, he's probably the most skilled/knowledgeable machinist I know on RUclips and he works on an RF-45, so that's saying something. If you can get one of those used, I think that's a great starting point for a garage-type hobby shop, unless you want to go the used-industrial route, which is a whole different rabbit hole.
