Thank you for taking the time to learn English. Coming from a person that speaks two languages I know how hard it is to think in your native language and talk in another language. I have been looking at your other videos and also find it funny that you curse in english.
Gday Bart, the 2 surface finish’s are chalk and cheese, definitely worth all the effort to get it right, sometimes you have to think outside the box to get the best solution for the job and that really worked with the bench grinder to eliminate the runout, absolutely brilliant job mate, always something to learn from your videos, thanks for sharing, cheers
Hi Bart, Static balance was succesful, the bent shaft was probably the root cause. Working in an oil refinery many years ago I used to dynamic balance electric motor rotors after bearing replacement on a Schenk balancing machine. Added weight by rivetting washer or washers on the round protrusions of the rotor or removing some material of the round protrusions.
Looking much better now,Bart. Definitely the right decision to fit high grade bearings from a reputable brand in the future. Even a simple bench grinder is greatly improved by balancing and fitting good quality bearings. Edit to add: I forgot to mention earlier that the shaft in this type of motor can usually be pressed out of the rotor and a new one pressed back in. I have pressed a couple out and flipped the rotor 180 degrees and then pressed the shaft back into the rotor. The purpose I did this was to reverse the rotation of the motor.
Unexpected video content 😆 Great set of videos showing the detailed repair of these kinds of devices and motors. Things I hadn't thought about before I know to look for in the future if I have issues. 👍
I don’t think it was so easy to diagnose the source of the vibration. The repair was really impressive. Does dressing the wheel come into play here? Does it have one? Anyway, nice work as usual.
Thanks. Yes first I thought it would be the wheel or the spindle. But then I noticed vibrations on the machine without having a wheel on there. So it needed to be in the drive system.
And yes. Wheel balancing is important. I did dress, balance and dress the wheel and sides before use. But that made no changes with the vibrations that I got. So it was not in the wheel.
goede surface finish op het eind ! maar staat die nog steeds op een pallet, want dat zal de finish ook niet echt ten goede komen ? wat betreft de motor pully, waarom bevestigde je die motor met pully niet op het bed van je draaibank, om daar de pully af te draaien ? groeten ben.
geen wonder dat ie niet rond liep na het draaien in de draaibank. hij was niet ingespannen tussen centers maar in een spantang aan de ene kant en een, weliswaar nieuw maar toch inferieur, draaiend center, aan de andere kant. en als ie dan niet goed in de vaste kop zit, en dat is eigenlijk altijd, wringt het en loopt ie niet mooi rond. alle afwijking in rondloop aan de zijde van de vaste kop zet zich dan door in afwijking in rondloop van de poelie. het beste is het de motor met poelie te monteren, zoals je ook gedaan hebt, en deze dan vast op het bed van de draaibank te schroeven normaal toeren laten draaien en dan afdraaien/slijpen. dan is meteen het probleem van onbalans in de as/poelie combinatie ook aangepakt.
Ik denk zelf dat het meer met onbalans en verschil in gereedschap druk te maken had dan de opstelling. Ik kon ook niet alles van het proces in de video goed laten zien. De spantang op de Schaublin draait erg nauwkeurig, binnen 0.002 mm. Het was een bewuste keuze om niet het center te pakken maar juist het deel van de as waar later de lager zit. Beide getest op rondloop, en de rotor zelf had in deze opstelling ook erg goede rondloop. Center aan de andere kant heb ik opnieuw erin gemaakt en ook nauwelijks beweging van de as als ik hem erin of uit haalde. Dus geheel best goed in lijn. Meedraaiend center is van prima kwaliteit maar losse kop die veel uitsteekt op de Schaublin 102 heeft zijn limit als het gaat om onbalans opvangen. Het slijpen van de poelie op de motor werkte uiteindelijk prima.
Thanks, I think the coolant system will be next. Or get my Deckel S1 running. Or the DRO on my mill, or on the grinder, or... Will see ;-). And our boy is doing great. Cheers!
@TheMudfly80 there are two manuals. One with tension instruction and the other with it. Send me a mail and I'll send you the pdf. BartHarkema at g mail dot com.
I have the same surface grinder, I have a problem with mine, the spindle that drives the Y axis? in and out, not left/right, is binding, and I can't see how to get the table off, do you have a video on disassemble the table ?
Very Good Video I have a similar machine & its belt gets down from the pulley. I've replaced the Anti vibration mounts of the motor. But when I am tensioning the belt, it seems that the rubber mounts gets bent and the belt doesn't get tightened. Can you advise?
Mine does the same. But make sure your belt tension is not to much. It should not pull the rubber mounts to much with normal tension. For tension. The hanging weight of the motor should be enough. Maybe a little more but not much.
Great result, Congrats!!
Thanks!
Wow, it was a lot of work, but then the result!
Unbelievable!
Nice work Bart.
Thanks!
Wow! That motor certainly had seen some serious abuse. Glad to see that you got it back in shape.
Great work! Thank you for filming and sharing. Looking forward to seeing a few bits you grind with your surface grinder.
Congrats, Bart, good job and you won.
Thanks!
You have great patience Bart.
Well done, much better surface finish now, nice job.

Very well done Bart. I have the same machine with the same problem so I guess I have a project.................!
very Good Work! Persistence won the day! I know you will get many good surfaces out of that machine now! And you learned some things for the future!!
Thanks!
wat een werk en geduld de laatste twee video's, maar wat een resultaat, petje af.
Dank je
Well done. I have just acquired one of these. A very useful run of videos. I just hope my motor spindle is not in the same condition as yours was!
Quite the better grinding quality👍
Yes very happy with the results
This is becoming the definitive 540 rebuild series. Well done on the motor repair it was truly a basket case when you started.
Very well done, congrats !
Also with the video’s, highly enjoyable and relaxing content again ! ;)
The proof is in the pudding, and the new part looks awesome. Great job, once again!

Thanks Matty, yes it made a big difference. Cheers.
Very Good Mr. Brat . Please shoot one video about Hydraulic system and leakage and how to clean Hydraulic pipes. Thanks
Finish looking good, excellent job Bart.

Mooi werk Bart!
I do hand work on precision musical instruments all day long and I am incredibly impressed by your hand grinding solution. Crazy, but if it works…
Thanks, yes I didn't think it would work that well.
very nice go on!! thnxs
Thanks!
Your patience and persistance is admirable. Is it possible that you will progress into watchmaking?😉
Mmm, The Watchmaking Blacksmith sounds like a good title ;-)

What happened to part 5. I was working 9 years working j&s Inc apprenticeship . I am very interested. Thanks Graham
Way to chase down a problem!!!
Nicely done Bart! Can't wait to see what's next. So how is the little one doing? Hope everything is fine. Cheers

We sell general purpose lathe milling machine repair in Korea. Nice to meet you.
👍👍😎👍👍
basically i am from india .i want to buy this machine . can you tell me how much price this machine in your country ?
How did you judge when the belt tension was tight enough at the end of the video? Can you make it slip with a lot of force by hand? Thanks.
It's not possible to slip it by hand. And there is a lightening instruction in the manual.
Thanks. Mine has instructions on how to tighten it but just says 'until correct tension is achieved'. I'll make sure it doesnt slip, should be fine.
@TheMudfly80 there are two manuals. One with tension instruction and the other with it. Send me a mail and I'll send you the pdf. BartHarkema at g mail dot com.
