- In this video i show how i machine the spindle bearing housing for my DIY CNC Mill.
I also talk a little about the taper angle i have machined into this diy spindle.
Check out the vido i made about the Diy Cnc Milling machine project that this spindle is off • Don't build a DIY CNC ... .

I'm on the same journey. As a junkyard enthusiast, I was lucky enough to be able to find a used ER32 spindle from a horizontal milling machine, it's not an ISO30 but it's better than nothing. I'm going to use a cheap 750W sewing machine motor, these newer ones are servo and come with an inverter. Good luck on the project, it's always good to see people trying their best to make their wishes come true.
Awsome mate its good to use the things you find one mans trash is another mans treasure.
That's a good score on the spindle pretty lucky right place right time I guess a.
I didn't know about those motors I will be keeping an eye out for them now cheers.
I bought a set of large angular contact ball bearings for a diy mini cnc lathe spindle. Since I got a cheap factory made cnc lathe before I got into building it, I'm probably going to build a 40 taper mill spindle from them. 85mm inside diameter on those
Awesome they will be some good bearings for a spindle. Cheers for your comments appreciate it
Just found your channel and Subscribed. Very nice work.
Thank you for the support most appreciated
Why is your lathe so rusty?
Hi there thanks for the comment. The lathe is rusty because I get alot of condensation in the container it's a constant battle. Once I build my big shed I will be able to give it a bit of a paint and remove some rust
What bearings are you using? Angular contact or just deep groove? How fast can they spin? It seems hard/expensive to get 20-30.000 rpm bearings.
I'm just using deep groove roller bearings for now angular contact bearings are expensive lol.
Yeah bearings are a big part of the cost in building spindles.
Nice spindle
Thanks, mate. just shows what you can do with scrap. I have now upgraded to a bt30 atc spindle.
Its recomend or no sir?? I want build wirh angular bearing for my cnc, how to make the steel not come for rusty??@@gingerninjaneering
@danielmeneses724 Thanks, mate. It worked, but I would recommend angular contact bearings. I've upgraded to a BT30 ATC; it's much better now.
@@botak333 definitely angular contact bearings. And I would say paint it or lots of wd40 to not get rust.
@@gingerninjaneering oke using both up and down or one only??
Hey mate, awesome build, subbed for more.
just wondering if you've thought about a non-manual way of lubrication/cooling yet? I've been setting up non aqueous misting/dripping (basically kerosene or isopropyl, pushed by compressed air) for my makerstore OX gear kit, and I don't even plan to mill steel on mine, at least for now.
Just noticed I don't think you mentioned anything about it in the last video either,
Greetings from Tassie :)
Awesome thanks mate appreciate it.
Yeah I have been thinking about using a pressure vessel pressurized by air compresser and then using a solinoid from a mig welder that can be controlled by the software to turn it on and off.
I will probably use normal cutting oil you mix with water but I don't see why anything else in the pressure vessel wouldn't work.
Cheers again for your comment.
@@gingerninjaneering Great idea!
Will be sharing along awesome build
Thank you I appreciate that.
I am on the same journey and I am still trying to get equipment together . I found a 1930's or 40's drill press /tapping station from a machine shop that was just opened up for an estate sale after something like 70 years. I was unable to afford the other machines but I absolutely wanted the tapping station. I have a lathe that is missing tooling but I ma still going through boxes. The girl that sold me the lathe had sold almost all the tooling and necessary stuff before I ever got there. Did I say sold. Sorry I meant to say that she gave away boxes and boxes because she had no idea what the stuff was. I nearly cried. She evidently sold a vertical mill for 200 or 300 dollars to someone who scrapped it. She learned her lesson on that one and would not sell anymore to anyone who would scrap anything. The damage was already done.she had been selling off her grandfather's stuff for months before I found her. I was able to buy two huge pull behind SCHRAAM industrial compressors, a lathe, a machinist's toolbox with some stuff in it, a completely restored valve reconditioning and making machine( Her Grandfather restored two and painted one black and one pink). I saved what I could. Her grandfather built race cars and race trucks for the Petty race team and had a great long life till 90 years old. Keep up the great work my friend.
o wow that is one he'll of a story. A real shame to hear about machine's getting scrapped when they could be restored and used and possibly cnc upgraded 😉. cheers for the story and the time taken to write it.
@@gingerninjaneering Absolutely my friend. The story is even bigger than that. I am a chemical engineer. My specialty is organ-metal transition catalysts. I was working for big Pharma when the plandemic struck. I was driving and riding 2 hours to and from work every day. I went to school and lived in Florida but I moved to Pa to help with my mother who contracted M.S. I was riding my 1957 Harley pamhead to work when I was hit, flipped up and around a telephone pole and the had my right leg crushed nearly in two. I was able to crawl up my dad's driveway while I felt like I was drowning. Luckily my brother was there to take me to the hospital because evidently the crush formed bloodclots which broke loose and went to my heart and lungs. The surgeons said I would not have lived six minutes had I not been rushed into surgery. I had to learn how to walk again (third time in my life). It was just the last couple m0nths that I was able to be up and do what I wanted. I realized that life is short so I decided to do what I love. I started a mobile welding/fabrication business along with a machine shop that will be powered from steam and a central belt system. I specialize in repair of small engines and equipment used for construction and landscaping. The equipment I see most of the time is obsolete and parts are not available anymore. I usually design the parts and 3D print them and then cast them from aluminum. If I have to I can cast other metals also. I am going to start my channel with that awesome tapper/drill press thing. I'll try and send you a link when I upload the shot video of it. Talk to you soon.-John
mate that is one he'll of a story you need to share that in your videos I'll be keen to see what you can do get on camera and go hard. all the best mate keep in touch.
@@gingerninjaneering Thank you my brother !!
no worries, mate all the best
I would have gone for tapered roller, though. A couple oversized (ID) sealing rings, two locking nuts, a washer made to fit and a shoulder in the spindle it's pretty much all it takes. It will get you twice as much precision than angular contact for the same price range, twice is much axial load handling for the same size, and can use oil as lubricant, which beats grease any day. The only downside being tapered roller bearings do not tolerate relatively high speeds even for short periods.
Cheers for your comment that is a bit of food for thought. The speed wouldn't be too much of a problem as my servo top speed is only 3000rpm.
I'll keep your advice in mind.
Nice work. How did you go about getting your spindle absolutely trammed?
I shimmed and packed everything. I have now pulled the machine apart to put in a proper bt30 auto tool change spindle. I have set all that up with a laser level, and then when I put the machine together, I will use dial indicator to tram everything in accurately. New videos will be out soon
Very nice your shared cnc
Thank you for the comment. There is more to come on this machine in working on upgrades at the moment
First you put your taper bearing into the pipe afterwards there should be a spacing sleeve then you finally put in the ball bearing that has the seal this way your grease will always remain in the pipe and a sleeve acts as a support for everything between ball bearings
Hey there, cheers for the comment. yeah, I definitely made poor choices on that one, lol. I know what to do for next time now. have you seen the upgrades video? I have a nice new bt30 atc spindle to go in.
th-cam.com/video/OWsy3WpL9tA/w-d-xo.html
@@gingerninjaneering you will have to do that why is because the regular bearing that you have put in it's not a side to side pressure bearing you will be constantly replacing that if you do not have a taper bearing in there
yeah, I was being cheap and had those bearing laying around as proof of the concept it worked. But I have come to my senses and brought a proper spindle with proper bearings and automatic tool changing, so this will eliminate the issues.
Nice, doing the same on my Small shop jajaja but I only have a woodlathe for the turning so it's soo scary to mess big chunks of metal on it...
Thanks mate.
O awesome love the diy.
That sounds very scary lol hope you have a face shield.
Hi, I have a question, that collet that you bought it has a tapered end. That taper doesn't rest against anything right? It's just the flat part that touches the bearing housing?
hi there, yes it just pulls upto the flange and relies on the 30 taper to hold it. the new spindle going on is a bt30 atc and has a pull stud and drive dogs aswell as the 30 taper and proper angular contact bearings. New videos out soon with the sevo upgrades and spindle upgrades. anymore questions let me know and I could make a video.
Friend, can you please answer some questions for me: Are the linear guides 25mm? is the ball screw the sfu1605? 1kw servo motor? Could it be that the sfu1605 is not too small for the machine? with this ball screw 1605 the machine can machine iron?
Very cool. I like your videos, but can we get a few guys together and send you some Evaporust? Lol Can’t wait to see more…
Thanks mate.
I would love some evaporust maybe they should sponsor the channel lol. It gets very moist in the container with condensation I do have some fans running to try to minimize it but it's hard.
Hope to build a big pole shed soon and have a concrete floor.
Thanks again for your comments most appreciated.
spray every thing with wd40 wd stands for water displacement keeps oxygen dan water of your tool and froms rusting
@@3kikass thanks for your comment I have tried that a few times but I probably need to do it more often
@@chrisvt3014 yeah every time it rubs off or washes off
@@3kikass yeah pretty much I do have a pole shed in the process of building as money allows and then I will have a dry well ventilated place to work and keep the machines and then I shouldn't have that problem anymore.
Why did this get recommended to me... that looks absolutely horrible tbh. I guess the title was a warning of what not to do?
you spelled your handle wrong. @BitchBJ their fixed it for ya.
@@assyholey4224 I'm guessing the irony doesn't escape you in saying that, @assyholey4224.
My point was the video was listed as "Don't build your own until you see this" - like he has any authority on how a DIY spindle should be built, but no - it's just some bodge job of a spindle setup. 1hp motor. slapped a couple cheap ebay bearings in. no care at all to precision or tolerances. This may be how you build "a" spindle, but it's certainly NOT how you SHOULD build a decent CNC spindle. This won't achieve any decent surface finish, and won't last at all. So no, not a bitch, this video was objectively clickbait.
@@LitchKB my bad.
hi there @Litch so i took what you said and i have brought some parts to make some improvements on the machine. I built that spindle using what i had like most people on a budget. You will be pleased to know i have invested in a bt30 atc spindle with proper angular contact bearings a 3hp ac motor with vfd and servos to replace the steppers, i have also purchased a proper cnc controller board. I appreciate your comment and it has pushed me to try to do better. Im still working on a budget though. I understood the spindle i made was a bit of a bodge job and wouldn't last but i had to make do with what i had at the time. I don't consider myself as an authority in machining at all just a guy with a hobby for building things. check out my latest video to see the improvements i am making. th-cam.com/video/OWsy3WpL9tA/w-d-xo.html. thank you for taking the time to comment and the constructive criticism has been taken on board hope to earn you as a subscriber possibly one day.
@@gingerninjaneering Fantastic to hear mate, I'll have a watch after work today.
Hey champ, I think you should seriously invest in some micrometers, that way, you can plan your cuts to the sizes you want to hit. A bit of advice: if our target size is, say, 100.02 and you’re using a DNMGxxxx04, you really want to be aiming for a MINIMUM finish cut of 0.3 DOC, so you should machine to around 1.2mm over size, mic it up, write it down, then take your first finish cut, then mic it up again. Check your actual cut vs planned cut, then adjust your final finish cut to hit the final size. With a bit of practice you’ll hit size every time and get a good surface finish. And if you mic up the parts you’re trying to fit together, you’ll be able to plan the fits in advance.
hey mate thank you for your advice.
It is on the cards four sure to get some proper measurement equipment and get the dro on the lathe going the old imperial dial is hard to read.
I like the idea of using actual measurements than going back and forward test fitting.
thanks for you time appreciate it
@@gingerninjaneering cheers mate, good luck and have fun. Machining can be an art, for sure, but it’s certainly more of a science. Plan it out before hand and then find a way to execute.
I will do that in the future and upgrade my measurement equipment.
sneaky, like sneaking up on it. my very old lathe has no dials, but I can be very sneaky.
@@assyholey4224 my old manual lathe has way too much play and backlash so if I have to make a critical part on it for some reason, I put a dial indicator on the carriage.
Are you hand feeding the cross slide? No power feed?
Hi there I have power feed in both directions but I tend to just feed by hand I find it easier to stop and start that way.
Having trouble to relate to the title. 🙂Now that I watched it I think it was a click bait!
it was my second video and was going off what the teachers of youtube say. lol if it made you click, It must have worked, but yes I agree. cheers for the comment
dude, don't you have a few bucks for WD40? any machinist knows that if parts are made from mild steel they will rust a lot
lol, no, I spent it all on servo motors and spindles lol
LOL that's just so cringe couldn't get to the end.
I bet KERN Microtechnik are shitting themselves with you about to nick all their customers.
lol it was my first video and I agree but you got to start somewhere lol.
