Cà Lem holding down the house for us as we all go through Ol' Tony withdrawals.

[@alexiselsass1143]

Man the way you make stuff with recycled parts.... It just amazes me everytime !

[@ukulelefatman]

Great seeing another project. Stay safe, and hope to see more of you soon.

[@anmafab]

Was as high quality project and video as I was expecting Ca Lem! By the way, did you end up finding some more multifix tool holders? Also when did you pick up an optical comparator? You may have shown this in your prior vids but I can't recall it. Your workshop is really getting well equipped now, between the nice machines / tools you are buying and restoring, plus the stuff you are making! Love your work

Thank you man. I got some holders last year but never feel enough of them. pick up an comparator last few months. never got a change to give it some "spa" works.

Very nicely done CàLem! The front locknut will influence the runout of the nose even if all the parts are perfect. It is the squareness of the pressure face of the nut and the parallelism of the spacers that causes a deflection of the nose. By lapping the pressure face of the nut to remove material at the low point of tir when measuring on the OD of the nose you can get the nose to run true. You need to keep the nut face flat while altering the angle of the face. Also as you remove material from the nut face the tightened nut position keeps changing. This makes the process very difficult and tedious but is a skill that experienced spindle rebuilders must master. ATB, Uncle Robin

Thanks unlce Robin I did notice that on your mill bearings repalcing. Never tried lapping before. Definitely will get some compounds and mess around soon 🤓

[@Calligraphybooster]

Hello gentlemen, can the problem also be caused by the type of collet used? When tightening on this type of collet, you keep the diameter on one end as it is, while diminishing it at the slotted end. The taper consequently will vary, the more so when you have to tighten more. I would prefer ER collets for this reason. They have their slots alternatingly running front to back and back to front, so the taper is more likely to remain constant and will settle against the receiving taper in your arbor even if either is a minute of angle out of spec. Have a nice day!

[@ROBRENZ]

@@Calligraphybooster I agree with your comments about collet style but I am talking about the runout of the collet seat surface not the tool shank in a collet.

[@Calligraphybooster]

-thanks, I got you wrong😶.

[@caffienatedchaos]

You did great! Eliminating runout of anything less than .001 mm on hardened parts is always tricky, and usually leads to more headaches than it's worth. Great Job on showing your engineering skills, Ca Lem!

[@kabyla8351]

The belt is flopping, you need to tension it. Keep it up, you're one of my favourite machinists to watch. 👍

[@TheHelmarocKing1]

I really appreciate you showing the process of the failed motors. This is one of my favorite channels!

[@darrensworkshop6783]

Never give up..

[@alexeyzdec2316]

Как всегда, приятно смотреть на аккуратную и точную работу. Крепкого здоровья!

[@Preso58]

Making your own grinding wheel! That's heroic right there. Your lock down must be bad. Too bad about the motors.

Thank you sir 😘

[@reiniertl]

Look into industrial sewing machine motors: fully enclosed, powerful, compact and silent. They also last "forever". You may also use a different pulley ratio to increase spindle speed.

[@Atlantismonkey40]

No matter how much planning, sometimes we’re the dog! You do have a very good ability to try. That’s were the real genus comes from.

[@buildmotion1426]

I always look forward to your videos! Nice project.

[@MF175mp]

Nice idea to have the collet nut and shaft work as a direct clamping arbor for larger grinding wheels

[@amundsen575]

The rear bearing arrangement needs a wavy washer for preload and to allow for shaft expansion

What you said is mostly for regular bearings application. Or angular contact bearings but different type of set up compare to mine. Not wavy spring, it should be a number of coil spring and thrust washer, precision made, properly set up. If not, it wont worth the price and whats angular contact bearing made for.

[@MattysWorkshop]

Gday CàLem, awesome job, the runout in the spindle is is next to zero, brilliant design and there’s many of uses, I ground the MT 3 spindle in the universal head in the Cincinnati with a bench grinder mounted to the table, made an arbor extension with a stone and went for it, very slow job but got the run out down under a thou, pure luck I think mate, great video as always, hopefully you guys will be out of lockdown soon, take care, Cheers

Thank you Matty. 😉

[@alexraven8329]

Большое спасибо, желаю Вам терпения.

[@metricstormtrooper]

You are a truly brilliant man Cá Lem.😀👍

[@rickpalechuk4411]

Maybe a 15 Amp variable speed router motor? Always enjoyable content, thanks for sharing, Cheers

[@CraigsWorkshop]

That's a great idea. Fairly portable, powerful for the size, and often has speed control built in.

[@FloweringElbow]

Enjoyed that. Thanks for sharing.

[@yeagerxp]

Excellent work 👍👍👍 . Thanks for sharing. Stay safe

[@bigbird2100]

Great video 👍 Ca'lem thanks for sharing your fails and success and your humor is always appreciated.

[@TrPrecisionMachining]

very good job ca lem

[@DungVu-db4ql]

[@accckiy]

Nice. Interesting

[@okgroomer1966]

Shops in CT around me would pay this man a handsome amount to be their tool maker. Seems every shop has been looking for one for years. Hope these skills are providing you a comfortable living.

[@LongOsramShop]

Dù không làm cơ khí nhưng cũng không bỏ lỡ các video của a bạn này. Rất thích 1 người tỉ mỉ và chỉnh chu.

Thanks bác nhé!

[@5tr41ghtGuy]

I've been thinking about building a powered tool post spindle for a while, for grinding and milling on the lathe. Yours is my favorite design - in particular, the ease with which the belt can be tensioned and the motor swapped out is very appealing. Bravo!

[@PiefacePete46]

Your engineering ability is always a pleasure to watch... your video and editing skills get better and better! The extra little funny touches really made me chuckle. Thank you so much.

[@ramonching7772]

Other people produced a baby during lockdown. You produced a baby spindle. 🤣🤣🤣

[@chopper_1987_]

All time looking awesome ❣️

[@EmmaRitson]

nice!!

[@kitmaira]

Lockdowns are pretty much history here in the US, except in some of the more stubborn states. Hoping that it gets back to normal for you soon.

[@thomasfischer6548]

For which new spectacular project do you need your cool new grinder tool? I am always fascinated!

[@peteraugust5295]

I built a really simple holder for a airdriven 20€ grinder to grid some chucks. Worked well. The only problem was the massive air consumption, which lead to a noticable change in rpm and believe it or not, in grinding disc diameter. I had to ensure that the final pass was always done with a full tank of air or it would not cut material after the previous cuts.

[@waynec369]

Definitely more convenient than having to remove the QC toolpost. Excellent work!

[@frodobaggins169]

I just found your channel. I must say: I am quite impressed with the way you think and the way you learn by doing and making mistakes. Mistake are golden! Great job and hope to join you on more of your journey. You are very talented. I'm from America were we buy everything!

[@homemadetools]

Nice job as always. We shared this video in our homemade tools forum this week :)

[@TheEvertw]

Nice work! Sorry about your power scraper... Be safe!

[@willi-fg2dh]

6:34 and 6:41 - CaLem demonstrates the world's strongest thumbs . . . 18:20 CaLem notices his error and uses the arbor press. [ keep up the good work! . . . a lot of people enjoy watching you work, it's better than getting out of bed and doing it ourselves ]

[@HP_rep_mek]

Nice build, you will get it better and make it perfect in the future👍

Thank buddy. or i will just destroy it on the press

[@sharkbaitsurfer]

When you find the correct motor, you've got it sorted, all the hard work is done and you've got some serious skills, very impressive

[@slimel-gharbi8170]

Again, another great example of your ingenuity and skill! I wish KZbin had notified me about this a week ago when the video was actually released.

[@jakubkopec9313]

Thank you for your beautiful work. You inspired me to buy a milling machine and to start learning machining.

[@stavroscharalampidis2154]

I did the same in Greece. I holded it on Multifix B. As stone I use 100mm. As motor an angle grinder Flex 1400w, 2500-7500rpm. Front bearings 52/20 Back bearings 42/15 (2 pieces in both sides). Works great without chater ! Thank you for your ideas ! Regards from Greece

I'm a 75 year old spent many years working in aircraft machine shop in UK....your skills with manual machines only remind me of those days... Thing's changed with CNC tool's... Never give up on yourself, your dreams and aspirations, Good luck with everything you do.

[@okgroomer1966]

One of my tenants has a bunch of CNC's in his shop. Not one person in the shop can run a manual mill. They're more computer programmers than machinists if you ask me. They still make quality parts, but how they get to those parts is a completely different world. I'm not sure they could make anything by hand. At the same time though they can make parts far more complicated than any manual Machinist could dream of.

[@opieshomeshop]

*_Those wheels need to be spun at their rated RPM. That face mask wont protect you at all and if you think I'm BSing come visit my shop and I'll show what an exploded grinding wheel did. I left the pieces where they landed and some of them embedded into my shop door. They are still there. Dont chance things in the shop. Esp when its your safety on the line._* Putting a guard on that wheel and protected other areas of your lathe is also needed when operating this.

[@xyxVULCANxyx]

Great skill, as always. I suggest building guards for the stone and the belt. At those speeds, a face shield might not be enough in the case of serious failure. And having a piece of the stone embedding itself in a hand/arm/chest or getting a whip from a belt thread is not much fun, either. If you want to use induction motors (like the two you tried first) you'll need to use a VFD, otherwise you're limited to the mains frequency, i.e. 3000 rpm for 50 Hz. Using pulleys would to increase speed reduces torque, requiring an impractically large motor. Regular 50 Hz induction motors usually work fine at 100 Hz (I use this setup on my mill).

[@robertnicholson7733]

The best way to protect yourself is to ensure that, as much as possible, you keep your body and anything else important out of the plane of rotation of the grinder. I always keep myself as far as possible out of the plane of rotation when I am using any rotating machine. Personal protective equipment is important, but it is in the third level of safety, first level, is a safe workplace, this includes the machine itself, ingress and egress routes, correct unobstructed working space, machine maintenance, etc. The second level is proper training, and the third level includes personal protective equipment and "magic". Magic is things you can't see but can only assume are working, this includes things like stop-saws, earth leakage breakers (core balance devices, and the myriad of other names that have been used for earth leakage breakers) - WARNING these only protect you if you are connected to earth, if you are insulated from earth and become a load across a high voltage circuit, the breaker will not trip and you will be toast. It is amazing how many people seem to not know this serious issue.

[@jakesworkshop2629]

Stop messing around on machines and do me some art bro 😘😂

Yes sir!

[@philoso377]

Your video is inspirational. Concept on page 8:16 has four bearings 1, 2, 3, 4 from left to right. Could we made it in two? Either 1,4 or 2,3 ?

Yeah we can. But we need a specific springs preload mechanism to prevent distortion.

[@andyZ3500s]

Ca Lem, I love your video's and think that you have alot to offer others but I also think that people would get more out of your channel if you talked in the videos. I understand your English better than some people who are from England.

I was about to do it but kinda lazy and tired after a month messed things up.

[@arunkumarsawant6523]

Want to build a SPM for spiral. Seen you video on flat spiral. Attachment to lathe gives coordinate movement inward and outward. But using two different motors may not work. Give your insight.

[@jonathansmith6390]

Try a BLDC or brushless dc motor. High power density. I'm using a 500 watt nema 34.

[@Calligraphybooster]

Always like your projects! It occurred to me that you might balance the axle. The meat you left in the middle is also where you vould take away a fraction of material.

[@TRUCKTUBEGAME]

Abrasive in a lathe ?! The machine cannot be saved from slow dying!

[@otakarjezek2670]

To left some meat in the center of the shaft to minimize distortion from belt tension is not good idea. A large gap between shaft diameters means large machining. In rolled bars, a large internal stress may remain from production, which is released during machining and leads to deformation of the workpiece. Therefore, it is correct to rough the shaft, anneal it, and only then finish it. Furthermore - the shaft should have only one bearing to limit axial forces. With the existing bearing, axial stress can occur between the two bearings. Two bearings with angular contact are unnecessary, actually harmful. I recommend that you place the shaft in the same way as, for example, in lathes. Bearing at the working end of the spindle is proposed as axial-radial, for example with tapered bearings, while bearing at the non-working end of the spindle is purely radial. In this way, the radial clearance of the spindle can also be adjusted during the gradual inevitable wear of the bearings.

[@MRNVCDIY]

Nice video my friend

[@chiraz111]

I love that you added a 2:1 ratio in there after the first try! That's a super great way to quadruple the torque to load ratio...

[@jagathmithya719]

Did you dress (w/ diamond tip) & true up the grinding wheel every time you mounted it? Important for a good finish.

[@triNguyen-ml8xd]

Chú có cục đá mài , bị bễ vòng ngoài , hôm nay coi cách làm sử lý đá mài của Cà Lem chú thích quá , đễ chú thử coi được không , cục đá đó 35cm , lổ 2mấy , nó bể mặt ngoài khoảng 3cm , nếu sử lý được cũng còn 28 - 29cm hả Cà Lem hả

You should have tried swapping the pulleys abound, the larger pulley, larger pulley on the motor, and smaller one on the grinder… very nice work though…

Did you ever get the ways lapped back in on the Nicco grinder? Didn't know Teclock made integrating tachometers. Perhaps I should look into one.
