From Broken Pump To Belt Grinder Motor | Making A Drive Wheel WITHOUT Lathe
HTML-код
- Опубликовано: 17 окт 2019
- Broken pumps are a great way to get free motors for projects! Got this one for free with cracked pump casting so the motor was bound to be scrapped. In this video I show you how I make all necessary parts to convert this pump to a belt grinder motor and cast a fitting aluminum drive wheel all without using a lathe.
Just a little disclaimer:
Of course this is not the best motor for a belt grinder.
Of course this is not the best way to make a drive wheel and for sure it's also not the safest method to turn a true wheel on a motor.
This is just my own way of doing it, I just want to have fun and experiment with tools limitations to prove it can be done with decent results.
Fun fact:
This drivewheel runs more true than the one I have mounted on the 2x72 belt grinder. And that was turned on the lathe! (mind you, turned by me, so it's no surprise)
I just started to list some of the stuff I use for my projects in this amazon storefront:

Index of operation and materials:
0:37 This part needs to be shortened to expose more shaft
1:26 Clean up the cuts with 2x72 belt grinder
1:44 6mm thick steel mounting plate cut with angle grinder
2:09 Rough mark of mounting holes with spray can
2:20 Mark and center punch precise hole locations
2:40 Drill holes for bolts
3:25 Spacers needed to mount the motor securely
3:52 Mark position of shaft hole
4:00 Drill shaft hole
4:53 Design drive wheel pattern in Fusion360
Tip: Always add drafts to the walls of your pattern.
Note: Casting a true hole is hard, even with drafts!
5:08 3D print in PLA
5:20 Clean the pattern with box cutter and sandpaper, the smoother the better
5:44 Talc powder
5:55 Petrobon sand, specific sand made for metal casting
Can you see the mistake I made with the mold?
8:15 Molten aluminum, degassed with sodium carbonate and fluxed with specific aluminum flux
9:40 Cut sprue with metal cutting band saw
10:11 Grind off flashing and flattening the back on the 2x72 belt grinder
10:35 Mark the center with a forstner bit wide as the shaft hole in the bottom
10:50 Drill the center hole, this is crucial for the wheel to run true
11:11 With my mistake in the pattern I had to carve out a bit of the back side to prevent the final dirll bit to go sidewat (drill bit move when cutting in one side only)
11:31 Final Forstner bit, rills accurate hole but it's meant for wood so it takes a while
12:00 Grind groove for seger with rotary tool
12:30 Grind groove for shaft key with rotary tool
12:59 Cut key channel in pulley with jigsaw, yep, it works!
13:35 Started to turn the wheel true with an angle grinder but it was too slow
14:00 A sharp chisel works way better
14:26 I found the best one was a small woodworking chisel with a very thin and sharp ege, I guess the less contact area the better it cuts
15:26 Checking for roundness. Good enough for my application!
I would suggest against turning the inside of the wheel by hand, it's a bit dangerous.
The mass of the wheel compared to the motor rotor for a motor as big as this does not count much for balance. I Checked the wheel for balance and was not able to find a "heavy" spot, so I did not drill any hole to balance the weight better. But yeah, that's was the plan!
Thanks a lot for watching, I hope you liked the video!
Suggestions and comments are welcome.

Have you noticed the big mistake I made while making the mold?
If you want to know more about any particular process shown in this video be sure to check description, I always write a very detailed list of operations and product used.
If you like what I do consider supporting me so I can keep on making, join as channel member or check my Patreon for early access and voice-over edit of my videos. Thank you!
Something with the arbor hole?
Casting too big for the bucket? I noticed you had to turn it over and it seemed uncomfortable. Don't know if cooling it faster makes a difference.
Nice video as always. YOu really need to get a lathe tho XD
No draft on the outside surface? But if there was more material it could take a month to whittle.
He forgot the keyway!
Also some screw holes would have been good to build into the print so they would be strong enough to remove the positive. Drilling into a 3d print to put screws into isn't strong since at that point you only have a very thin amount of material for the screw threads to grab.
I have a similar motor from a rooftop AC unit. I needed this video, thank you!
Great work, as always.
Very impressed o your skills! You gave me inspiration to finish my work with an lathe! Best regards from Sweden!
When life gives you lemons, make a really terrifying lathe, then a drive wheel. Nicely done.
LOL a really terrifying lathe lol, good build but yes :)
God hates a coward, face your fears and live your life
Aesdtttttyyyyyhyyyyuuhuhhhhhhhhhhh
@@gullreefclub jjjkjkkkkkkjjjjjjjjkki
That casting came out super clean!! Love the turning of the wheel and how accurate you got it. Brilliant job!! 👍👍👍
Accurate, but out of balance. That will eventually vibrate itself apart.

Dude I can't believe it, I scored the exact same model of water pump last year, with the same problem, for the same build! 😄
I have make many parts with my drill press using it as a lathe many sleepless night thinking of how to design parts for projects, working on this belt sander design now
well done. I love to see how you solve problems. Most people myself included would order a wheel, or complain about not having one, not you. Cant wait to see the next video
YES!!!! Awesome vid subject. Watching later. Doing it next week. I've got so many motors. Surely one might work
Great work! Thank you as usual for sharing your experience! Regards!
I really like how you made that mold. Great job.
Thank you for sharing as always you produce a good video with awesome results, have a nice day.
wow man! I have always wanted a 2 / 42 belt grinder and have thought about maybe trying to build one. This was an amazing way to get a motor for that. Nice job, hats off, you are very skilled.
Great video. Awesome build. Looking forward to seeing it up and running.
I have to say... This worked out way better than I thought it would. Nice!
No comment, just..
⭐⭐⭐⭐⭐ for you. Thank you, brother 🙏
как всегда на высоте молодец , руки растут откуда надо...
Surpreendente!! o cara esta em outro nível!! 👏👏👏
Você é um artista, parabéns!! 👍👍
i specially liked the tapping parts :D
Awesome!.... I have a similar motor sitting around... I'll make a third grinder just for fun
There was so much good in this video that I can’t even rn
Really cool project! I love seeing all these great ideas that I feel I can use some day...
Thanks to you i will make it for my work shop with washing machine motor. Great thanks n cheers
Parabéns ficou muito incrível 👏👏
Great little show and tell. I was wondering why you hadn't used the lathe to turn the wheel, until I read the description and understood that you were showing it could be done with minimal tools.
I would say though, that motor sounded knackered.
Agreed. That motor sounds like it needs an overhaul. That noise would drive me crazy.
That's a great idea. Nice job and thanks for sharing.
Pedrollo: the owner of the company, Mr Pedrollo is a great man and a real gentleman, and the company itself is a beauty!
Молодец! Смотрю всегда с удовольствием! Но всё же, не забывай про технику безопасности на работе.
Excellent idea. I just notice that there is a little wobbling on the final result. I believe this is because you should turn it, on a real lathe (ask a machinist fellow), on both sides internal and external. About the rest, you have done an excellent job.
the motor wobbled in the beginning
Very nicely done. I have an old pump motor in the back yard. But I don't know if it still works. If not, I could always strip it for the copper.
Ooòoooò I've got one of those. Well more than one. Never thought of yousing it for that. Just need to get a belt sander to make it. M
That trick for the keyway and circlip with a Dremel, damn! Good tip
I really like your work. I look forward to watching your videos
Great work as always!! :)
Bom trabalho 👍 parabéns
You've got skills man! Nice! :)
Iconic worthy of appreciation 😘😘
How would the casting strength be affected if it were allow to air cool?
You got some real gangster techniques there, well done!
i learn so many way ,your my teacher.
Отличная работа. Продолжай в том же духе. Молодец.
This is just the sort of thing I always do with old pump motors !! - Please take that fan cover off ! and make sure that the cooling fan blades are not catching anywhere !! - That is an Induction motor you're using and It should run MUCH quieter then what it is doing in your video, so clearly something is wrong causing that motor to run so loud ! - I think that the rotor bearings are OK so that only leaves the fan cover that is the cause of all the noise ! - Fabulous video and superb metal casting skills - WELL DONE 10/10 !
I think maybe it sounds different because he has sped the video up on everything.
I heard it at the end. Yeah it sounds rough.
@@lucaswelshmusic7607 Yeah, Its definitely to do with the fan and fan cover, it could be that maybe he pushed the fan onto motor rear drive shaft too far down (if the shaft does not have any shoulders to stop this) Thus, that is then causing the back of the fan to slightly 'rub' against the rear motor end shield and causing the motor to run louder ? ....I know a lot about these sort of motors, as I work with a lot of them in my spare time and know how they are put together and how they should operate.
The speed at which your hand sands is superman level!
Great work, great video! 😁👍
May be a good idea to balance it to reduce vibrations?
Very nice casting work. I wonder if the basic motors bearings were the weak point in this project.
You are a master at your craft. Nicely done sir.
Great job loved watching the video.
hi there, nice video ! i was wondering what is the down side with using old water pump? like the power on paper seem totally enough..
Good job! nice idea...
maybe the camera was closer to the motor, but still the noise is higher than normal for a induction motor. you should change the ball bearings
Cutting your own key way was cool. Up to that point I was thinking you would have to lock tight that pully.
Thank you for a very different video!
Excellent work, good recovery. The bearings and the balance don't sound too happy but hey, free motor!
Sometimes the challenge outways the obvious. I wanted to jump through the monitor an offer my 13" SB metal lathe, but I realized it would negate the challenge ..... can it be done without a lathe? The vibration is my main concern as was mentioned. Possibly present before any mods were done? What's sound like with the drive pulley removed? Nice work and minimalist engineering!
I had a pump like that one but mine was a lot bigger. Motor was a 220 volt high speed motor . It would pump 60 gal of water in 1 min through a 1 inch hose.
Simply awesome!
Omg i loos my words Fantastico dakapo 🤤🤓
Great job. Enjoyed it.
I thought you did a good job of the drive wheel. The casting turned out really good. The lathing operation would be better if the cutter is stationary and fed into the work incrementally, when machining by hand the force against the work tends to follow the work so the out of round continues. Best to setup a jig that you can feed accurately like a sliding vise.
Question; what was the substance you added to the molten metal?
Pretty sure it was borax to help purify the mixture
Wow! That was amazing!
Why use a lathe when you have most tools, materials and implements already available in the kitchen? Cheers.
sei pazzo senza tornio! Ma t'è venuto bene lo stesso! Mitico!
Awesome hands working 👌🛠️
Well, "not WITHOUT a lathe" part disappeared when you use the motor as a lathe to shave / shape the wheel. Very good and impressive work. Thanks for sharing.
Very impressive. Nicely done for sure.
Поразительно, хотя токарная работа всё таки и была))))
Is that end plate you cut made from aluminium ?
Bravo Black Beard! 👍👍
Nice, i like how you start shaving with a long bar and then grow with confidence!!
Ok
That was more due to it not being round at first, and as it got closer to round, you can take off more with each pass. The last thing you want is a "catch" using a sharp chisel on an aluminum wheel at those kind of speeds. I had a catch turning a piece of aluminum on my wood lathe and thankfully i was standing out of the axis of rotation. Probably would have ended up in the emergency room or worse if i wasn't.
"" Hi ... nice video and fantastic things you build with precision and attention ...
I have a 1.13 kW engine with 1 HP and 2800 rpm. Not much, but unfortunately I don't have anything else right now.
I have read various information on the Internet from some who claim that the average tape speed should be at least 24-35 rpm.
What wheels and diameters do you recommend for my engine?
Thanks in advance.
N: B: I'm sorry if my Google translation isn't correct, but I hope you understand
1 hp is about 750 W, 1.13 kW is more than 1 hp. I think that the speed of the belt should depend on how big it is
Cool build, as always. Why not get yourself a set of transfer punches, or make a set. Awesome channel, great content.
I’ve been thinking about getting these
Are all water pumps pretty much the same as you go in to change to motor? I have two and would like to make woodworking motors out of them but don’t know too much about them. Are there other ways of changing them over?
Thanks, like your site.
Stupid question, but just wondering how/if the printed wheel would have held up under grinding tension?
Hey, interesting project as always.
But how can you change the rpm if the electric motor is turning to fast? Have you already figured that out?
You inspired me to inspect an old cracked pump which is still laying around. After checking if the motor is still okay, i could use it for a wire wheel or something like that.
@Josh Yingling Ah, thank you!
I know that it's probably fine, but what you were doing with that cutoff wheel at 12:00 was straight up spooky.
Edit: I just finished the video. The cutoff wheel was only like the fourth spookiest thing.
I have done that many times. Cutting a motor shaft to size by running the motor and pressing a hacksaw blade against it.
@Black Beard Projects
how did you connect the motor? can you see the connection diagram?
Good work Thank you.
What type of sand is that? You used to make an aluminum cast and where could I buy?
Awesome.. Brilliant job
8:10 Ahahah finally! 🤣
hello on the aluminum wheel try to install a rubber wheel for more grip
Обработка аллюминия столярным долотом...Теперь я видел все! Аж самому захотелось попробовать.
the one thing I didnt like was the sound of that pump motor... lol. I learned a lot watching the video though. Thank you.
С виду так просто, а мало у кого так получится!
As i see i need a belt sander to make a belt sander, seems legit 😂
And a 3D printer. I'd have put the plastic pulley right on the motor.
yep... too much of tools used just to make one tool... and using lead for the guide ain't the best response to that specific need. with a steel piston from a car or maybe a truck, plus a welder maybe end results would be better, w/o needing a 3D printer
@@jotabe1984 Better yet, you can have it done for a few bucks at your local machining shop. Regards.
@@jotabe1984 Good thoughts but pistons are aluminum.
@@ebenwaterman5858 I made my pulley out of Styrofoam, buried it in green sand, and dumped the molten aluminum into it, vaporizing the foam. The plastic pulley would have melted in a minute or two of use.
Is there any additive you use to the aluminum? A lot of guys talk about adding some copper to help with casting and such. But that looks like it came out really fine, no inclusions or anything.
Outstanding skill
Nice work! You should try to balance the wheel
Great modification.
can you also tell me the size of your wheels?
THANKS
Really too strong !!! I love !!! Great job. Well done 👍 Kiss from France
Top de mais meu amigo!!
Ah, Felce Azzurra
Incredible our projects
Haha... pedrollo pompe... ne ho buttata una da 2 cavalli. Se sapevo che si poteva frasformare cosi... non l'avrei mai buttata! Complimenti bel video
This ended in a strange spot.
"My work is done here."
Hi, I'm injoy to watch the video. What is the program is use to drawing the pully? Thank you.
Классно получилось. Друг, расскажи, как у тебя получилось так качественно отлить болванку, без пузырей? Спасибо.
смотри его видео про литьё,там хорошо показано,сколько иной раз он "переливает" по новой....
@@ai5085 . Спасибо. Видимо пропустил это видео.

"Without" a lathe hehehe
