In this episode I checked and corrected the linearity and parallellism of the headstock to the machine bed as prelude to the grinding of the MT3 inner taper and 3 jaw chuck.
Hi again Jaap, Did you grind the jaws in the chuck? I see that my jaws are also a bit off. Mainly I see that the jaws only make contact to the work piece at 1 cm farthest in. (No contact at the tip or in the middle.) So I think I shall grind the jaws very gentle and see if it improves. Another thing I wan to do is to replace the spindle bearings with better quality. There seem to be movement from the engine and pulley that en up in the chuck and work piece. Have you done any similar operation in your lathe?
Hi Wie verhallt sich mit dem Motor, in Dauerbetrieb? Sind mir Gerüchte um die Ohren gekommen, dass die Holzmann nicht für Dauerbetrieb ausgelegt ist, weil da noch Induktionsmotoren verbaut sind. Kannst du bitte darüber etwas noch berichten? Danke in voraus. Gruß
Dear Jaap Dekker, I watched his films in which Holzmann tested and demonstrated the ED400 lathe. I would like to ask for your advice, because I would like to buy a machine of a similar category for modeling and DIY. The two devices you choose are the HBM 210 Vario and the Holzmann lathe you use. The price and parameters of the two devices are largely the same. (Do you happen to just not make them in China?) So there remains an important issue even more durability and reliability. Since your film has been made for three years, I think you have gained enough experience. I would like to ask how satisfied you are with the machine or would you buy it again based on your impressions? Thanks to: Béla Baksa (Hungary)
i would like to see more videos regarding the Holzman 400FD. i do have a smaller version the 300FD and i'm happy up to now. With a good care you can cut steel. The threading procedure is a bit time consuming changing gears on the side but it works great.
Mr. Dekker you have to consider you future as a speaker and this is not a joke.Very worm, very musical, very clean and very deep voice.By the way i see your videos about lathe because i am planning to buy one.To create your videos in English shows also a polite man.Be well Mr. Dekker
You say the German machines would be accurate. What machines are you referring to precisely? Im a beginner but do not want to buy something out of alignment. Dont want to deviate from my path im on. Just want a good machine from start.
You can adjust the runout of a 3 jaw chuck,make sure you have a slight reduction on the chuck back plate spigot,then you can true the chuck,by tapping it true with a padded hammer.
Hello Jaap, thank you for your efforts in filming this series, hope to see Part 4 when you get it uploaded. I am looking at buying a lathe and have looked at the Optimum brand and also looking at the Holzmann brand. I am in Germany and these are widely available here. Would you buy this lathe again knowing the faults it has? Would much appretiate your input. I am looking at a bigger model than the one you have here.
Amazing explanation , Thank you i hope i can get metal lather before i retire.... , would be nice if you can make another video what type of work you can do on that size of the machine, biggest and smallest parts. Different tool combinations, maybe you have some tools that you made your self, and so on.....
G’day and greetings from Tasmania Australia 🇦🇺 as you said it doesn’t matter with these machines they are all built at the same place in China apart from Optimum lathes and mill are made in Taiwan they have a bit better quality. I have subscribed and look forward to watching your channel. Happy New Year kind regards John
Hallo Jaap Da sind Sie nicht alleine mit den Chin. Genauigkeiten. Ich habe das selbe noch vor mir. Nur ist meine Maschine etwas aufwändiger gebaut ist und der Demontage aufwand erheblich größer ist scheue ich mich im Augenblick noch davor. Aber es geht kein Weg vorbei. Ich habe mir jetzt erstmal eine Parallel Messtange MK4 gekauft und werde der Sache genauso vorgehen wie Sie. Auch die Drehfutter sind sehr schlecht in der Genauigkeit, das mache ich aber erst wenn die "Karosserie" in Ordnung ist. Sehr gut erklärt und auch für "Leien" verständlich.
There are better lathes but they cost more. This one is now functioning o.k. I am on a budget and then you have tweak a bit. Of course I bought this one new. You can also consider buying second hand. If you are lucky you get an upscale lathe for a reasonable price.
Hello Jaap! Great trilogy on the Holzmann lathe! I have the Quantum 210x400 and can totally relate to your issues and some more. Mine has been taken apart, converted etc. on more than one occasion by now. Still they are great machines with a little adjusting here and there, just as you've shown. And they are WAY above the common 7x14 mini lathes. I have another project for you: check the spindle bearings for lubrication ;) I've found mine to be almost dry by default, which is unfortunately very common with these machines (although it's not very known of, since barely anyone ever checks that). Pulling out the spindle required a bit of improvising (unless you want to relentlessly hammer it out), but at last i properly applied some grease to my bearings now. Waiting for your video on grinding the spindle's MT3!
Hello Jaap, Thanks for your very informative videos. Do you know where to buy the type of rod to true your chuck? Thanks (Are you still happy with it?)
Hi Jaap, nice video. (I'll stick to English for your other viewers) I guess we're both working in the same directions with out lathes. Mine is a PX brand, and I think the colour scheme is just a coincidence. You can phone a guy in china and start your own brand of Lathes tomorrow in any 2 or 3 colours if you like. Mine was a display model at a VDH in Utrecht. (It was in a price range just below the HBM counterparts which were out of stock at that time). from what I've been told with these lathes you get exactly what you pay for, the more expensive models (brands) are tighter on the tolerances and have better finish work. I bought a set of inserted cutting tools with my lathe, but in my 4-way toolpost these tools were a bit above centre height, so I had had to have my toolholder reworked a bit. I've already spotted a few differences between our lathes. I wonder does yours have the 'induction hardened' label at the end on the casting? and does the Rev counter circuit board have the Sieg marking on the PCB? Gr, Martijn
Hi Martijn, I thought you were Dutch watching your videos. It is indeed very sympathetic of you towards other viewers to stay with the English language. As far as I could tell from your videos you have virtually the same machine with some minor differences as I have. We both try to upgrade to lathe to european standards. I believe I did not see the "induction hardened" sign on mine neither did I see the Sieg marking on the PCB. Keep up the good work man, you are very inspiring to me.geetings, Jaap
had alle 3 je films bekeken jaap. en ik heb pas een machine bij HBM vandaan.. daar heb ik ook eerst maar gemeten en vond daar ook diverse dingen waar ik ook niet tevreden mee was.. bij mij moet het ook super minimaal ben dan ook ene pietje precies daar in. ook de machine uit elkaar gehaalf en met een klosje met waterproef schuur papier te weeg gegaan. ( paar druppels olie er op en maar schuren) zo ook de tailstok.. die stond ook aan alle kanten scheef.. ik denk dat we zo op het oog de zelfde machine hebben en chinees is lekker.. maar niet van draaibank.. had er ook veel verschil in.. maargoed er is best een prima machine van te maken mits je eerst zelf huiswerk aan gaat verrichten.. dan pas kan je zuiver draaien. even over de inbus achterin.. een wat oudere sleutel afgeslepen had je daar heel goed in kunnen gebruiken .. ????? gr
@@GaryRowlands yes it works well so far. The Chinese stuff isn't all that bad, you get what you pay for. And if you like tools and machines, like me, you can easely upgrade it to a higher level.
Thanks so much Jaap for informative vids . I,m between the 2 states of mind for buying this Lathe Hozman 400 or the Rotwerk 350dr. Do you have any idea about it? As the Rotwerk350 has got digital reader and a bit smaller , i,m more about rotwerk.but i like the metal gear for the Holzman. cant wait to see more video from you. cheers
very nice friend realy like all 3 parts. I dont have to much space so i bought 300fd Version. That is my first contact with lathe and i have question when i press green button and speed machine is on minimum she running about 50rpm i think she should not run beacause speed button is maximum turn to the left. Im right or every lathe running on minimum speed when they green button is on ? can u give me answer beacause for the moment i think my speed button is broken.
Hi Rafal 1987, you are right: my machine does the same, you have to push the red stop button or place the reversal switch in the center position. thank you for reacting.
Jaap Dekker thanks so all is fine 😉 i try running it and im suprise runout is huge when i have rod on is about 0.5mm. Chuck running extaly the same like your about 0.01mm but with rod is huge difference beside jaws running is about 0.2mm in lenght 200mm from jaws is 0.5mm that is realy huge. Definytly im sure the problem is with chuck jaws. Your orginal chuck was sanou Brand my is Different. Im sure i have to grinding jaws to get better result. Also i find the same problem with tailstock. I checked it on chuck and is going down about 0.03mm only in lenght 5cm so need correct that too. You do realy nice job with all 3 parts thanks

I really enjoyed your presentation. I did find the background music a bit distracting and difficult to hear your presentation. I think making the volume a bit less it will be better to hear you. Danka
the balltip of a hex ofter strips the hex in the head of the bolt better way would be to get a cheap hexkey and shorten the short end so it fits inside the pocket

Hi Jaap....i have at last 3 Days the same Machine. This little Item is a great machine to have many enjoy.
Many Greetings from Berlin Holger
Danke Holger. Grüss aus die Niederlande.
Love your soundtrack, Jaap, great piece of work. Thanks for sharing
Hallo Jaap, glad to see you making video;s again... Any update on this lathe?
Thanks for making this video.
Now I know what I can do on my Bernardo Profi 400. And may what I should do...
Hi! I like the way you manage the problems. I a fan of your videos. hope you will continue!
A question; are the chucks compatible with all machines?
Yes there will be more parts later this year. Thank you for asking.

Hello, I hope you are healthy and fine. I'm wondering how did you fixed the Morse tapering and concentricity.
Good question...I did not get to it because of some health problems.

Hallo Jaap
Da sind Sie nicht alleine mit den Chin. Genauigkeiten. Ich habe das selbe noch vor mir. Nur ist meine Maschine etwas aufwändiger gebaut ist und der Demontage aufwand erheblich größer ist scheue ich mich im Augenblick noch davor.
Aber es geht kein Weg vorbei.
Ich habe mir jetzt erstmal eine Parallel Messtange MK4 gekauft und werde der Sache genauso vorgehen wie Sie.
Auch die Drehfutter sind sehr schlecht in der Genauigkeit, das mache ich aber erst wenn die "Karosserie" in Ordnung ist.
Sehr gut erklärt und auch für "Leien" verständlich.
Would you recommend this lathe to a beginner?
I ask you this because you have made several adjustments
There are better lathes but they cost more. This one is now functioning o.k. I am on a budget and then you have tweak a bit. Of course I bought this one new. You can also consider buying second hand. If you are lucky you get an upscale lathe for a reasonable price.
Thank you so much for the video and for doing it in English!
Hi Jaap fantastic tutorial can not wait for episode 4 - thx a lot
Working on it.
great series of videos, for the difficult to reach bolts at the back you could have cut an allen key shorter which would have solved that issue.

Hello Jaap, Thanks for your very informative videos. Do you know where to buy the type of rod to true your chuck? Thanks (Are you still happy with it?)
Hi, I bought the rod somewhere on internet I'm sorry but I really can't remember where. And yes, I'm still happy with the machine.

had alle 3 je films bekeken jaap. en ik heb pas een machine bij HBM vandaan..
daar heb ik ook eerst maar gemeten en vond daar ook diverse dingen waar ik ook niet tevreden mee was..
bij mij moet het ook super minimaal ben dan ook ene pietje precies daar in.
ook de machine uit elkaar gehaalf en met een klosje met waterproef schuur papier te weeg gegaan. ( paar druppels olie er op en maar schuren)
zo ook de tailstok.. die stond ook aan alle kanten scheef..
ik denk dat we zo op het oog de zelfde machine hebben en chinees is lekker.. maar niet van draaibank..
had er ook veel verschil in.. maargoed er is best een prima machine van te maken mits je eerst zelf huiswerk aan gaat verrichten.. dan pas kan je zuiver draaien.
even over de inbus achterin.. een wat oudere sleutel afgeslepen had je daar heel goed in kunnen gebruiken .. ?????

How do you like this lathe now? I'm thinking of buying the same so it would be great to hear if you are happy with the quality and performance.
The lathe is o.k. now and does what it is supposed to do but it it is not a Schaublin
@@jaapdekker5983 No but it did not cost the same as a Schaublin so do you think it was worth what you paid for it?.

On another note, you could cut of some of your allen key in order to get it in there to loosen the bolts.. ☺ Thx for sharing.
I have a hex wrench that has short tip. This way you can use it to unscrew bolts with little space above it.
Hi. What happened with the lathe? Any part 4?
Great info.Am thinking about getting one of these.
Suggestion: confine the music to the credits
So am I, just working up to taking the plunge, it seems there is nothing so bad that it can't be fixed, for the money it seems like a good model.
nice and pricise video,mr Dekker..thank you
You're welcome
I really enjoyed your presentation. I did find the background music a bit distracting and difficult to hear your presentation. I think making the volume a bit less it will be better to hear you. Danka
You can think of Wabeco for exemple.
Very good gudeline 👍
Very nice vid! I really wait that next episode :)
Hi. When you do next ED400FD video?
6:20 - next time just take another allen key and cut it to the lenght...
What's the name of the best German lathes?
I cannot hear your words on this session, only the music for the first 2.12 minutes of video.....
the balltip of a hex ofter strips the hex in the head of the bolt better way would be to get a cheap hexkey and shorten the short end so it fits inside the pocket
I agree
Thank you for video!
thank you for watching.
Very Very good Video
thank you for watching ChristianCohn,
Thanks for this good trick.
The music is driving me away.. its great but why here?
Thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
you are welcome
I guess dolls houses was more urgent then the lathe?
Well I´m of to a, hopefully, more lathe oriented channel! Bye bye dolls!
Bye
Impressive, but far too much work to achieve at most marginal improvements.😰
Lose the music...
Bravo Kaap Dekker...🙏💪
