You can use this maho to machine the MH 600, you have the prints
I served my apprenticeship under a German toolmaker who had 52 years as a journeyman. He was serious old school. We had a Bridgeport, a Maho and two Mazak mills. Every machine was spotless. Well worn and well used, but spotless. You didn't DARE leave a machine dirty at the end of your shift. You did every pre-use maintenance like oiling and greasing, you used it only for its intended use, and it was cleaned and wiped down before you left. And if I was milling, he would ask me how I got the speed and feed for the material I was working on. You NEVER just guessed. If the Machinist Handbook called for a chip load or .015 per tooth, you had better be close to that or you were in for as ass chewing. I hated him at first. So irritating. But then died and the lessons I learned and the work habits he taught made me a great machinist. Now, I love him, and miss him.
I was taught that too in school. To look after the coolant, grease everything nicely before getting on to it etc.
I am in college to become an industrial technician, we get a year of milling and turning (at least 6h a week) they teach us a lot about safety and how to take good care of these. We have 14 kunzmann’s a deckel and a Hermle (5 axis). Along with 14 basic lathes a few mazak’s and some other exotics.
Compared to other colleges in similar programs its a lot tougher, requires more elbow grease and discipline. But we go to Germany every year with the 2nd and 3rd year to visit factories to see how they make the tools and machines we use. We learned about the german apprenticeships and vocational program. Some of our professors took home some of the things they learned from the Germans.
Every machine was to be checked at the end of the lab, to see if it was greased, cleaned and back in the state we received it. Feeds and speeds had to be written down and calculated properly, as you said. Not pulled from thin air. Formula was to be known by heart.
We also learned a few welding processes, cabling of electrical cabinets, how to troubleshoot these, combustion engines and mechanical work like working with couplings, gears, chains and belts. Along with electric motors and transformers.
Hence us getting a very “German” way of learning these things 😂 but at least it turns us into careful professionals with discipline, knowledge and attention to detail.
Shiiiiiiit he didn’t buy it & he was on somebody else’s time. Hopefully they paid him his worth.
@@codygooch510 Oh yeah. He was probably the highest paid in the shop.
I'm not crying I swear

Greets from Germany,
Congratulation for buy this heavy milling Maschine.
We use the MH 500 maschine in the Shop, and it works very fine after 30 years. The 400 in the name MH 400 is the length of the x- axis.... and MAHO is one of the best producer for heavy machining in the '70-'90 years in Germany. After the 90 it's fusion with the Company "Deckel" and the Company "Gildemeister and named sincely "DMG".....
ENOUGH history😆.....
In Germany , much of this machine's where are totally overhauled and sell's for 8.000-12.000€
If you need any help with the machine or the control send me a email and I support you much that I can.
Have a nice time with your MAHO
And greetings from Germany
You seem like a nice guy, Manuel, can we be friends. I dont have any German friends.
ATLHooligan looks like you will continue not having German friends..
@@sirjaye8884 sehr gute hahaha... what's more fun than an automatic Manuel! :)
Fawlty Towers springs to mind, Basil hanging the moose head.
Get me a hammer Manuel!
Hammer?

Whatever you do, don’t mention the war! 😜😂😂👍
Mahos are very rigid and accurate machines... or at least the ball screw machines were. Mr father worked on these machines for 40 years. Maho merged with Dekel, then Gildemeister and later Mori. DMG, maho deckel gildemeister. Does this machine have glass linear scales? *nevermind* lol
The lack of doofus dimples in the t-slot table is a great start.

Clearly, the other hydraulic lines should be repurposed to power the important ancillaries. Essential stuff. Bottle opener, foot massager, burger flipper, etc.
The Fuses are E27 (like the Lamp socket) and Called Diazed, Still pretty common in legacy Electrics in Germany.
Something makes me think this guy knows exactly what he's talking about.
@@geraldgepes Quite common in old houses in Norway too, we had sexyer holders tho Change'em for type C automatics
We Germans love fuses and still like to use them in new equipment. A breaker will wear with every trip - a fuse is always new and in mint condition. Also, fuses will prevent idiots from trying to power up broken equipment a dozen times before getting somebody who actually knows what he's doing...
We have them hear in Brazil too. I should say that you can still buy them but they are being fazed out.
@@meosalami5180 There is no fun if you know what you are doing.
Who finishes first:
A - ToT's CNC MAHO conversion
B - AvE's bartending robot
I got 10 bucks on the HO!
5 on the CNC MAHO conversion
If it’s skookum, she’ll chooch....
B. But only if he goes back to the fusion-powered iteration.
... Unless ToT does something timey-wimey.
C - Physics Anonymous' lathe rebuild ?
As a DMG MORI employee and a ToT fan, this project gets me excited! I run our factory Makers Club and one of our members, a production engineer, is doing something very similar.
Dear Tony
The other Tony at lathes.co.uk (a machine tool archive), in the "Millers and Jig Borers" part, has a section on MAHO milling machines and he does seem to have some catalogues and manuals (in English) available.
Hope that may be of some help.
Paul
Thanks Paul!
Paul, you are the hero that everyone needs.
@@ThisOldTony and if you still need some translations you might find some pesky germans here lurking around and some of them might even be willing to help...
@@ThisOldTony Pretty sure the 1:1 transformer is a safety feature, there to electrically isolate live wires on the inside of the machine from earth so that theoretically if there's a fault and you end up touching a live output there's no circuit through your body and earth, protecting you.
If the live output of the transformer touches the case and gets connected to earth (you said there was some water in the case), then it will be grounded and the "neutral" output will become live. The machine might continue to work (for a single phase at least, I'm not sure about a three-phase system.)
Obviously you'd still get shocked if you touched the live and neutral outputs or at the same time-I don't know if there's a fuse that's meant to blow if there's too little resistance between the two, maybe that's why it's not working)
@@mariuss4766 paging Stephen Gotteswinter, paging Stephen Gotteswinter.
There was also a "real" CNC-version of this machine. It was called MAHO MH400E and had a Philips 432 Control. It was equipped with three servos and ball screws. As your machine is the P-version it should have a Heidenhain TNC121 control. The E-version was introduced later and was just a modified P-version to fit the 432 Control which was able to do 2.5D machining. Later versions could even do fancy things like "helix" and threadmilling. The E-version had also a gearbox combined with a variable speed motor which was operated by the control. Here in Germany these machines are still quite common and they have a very good reputation being accurate and durable.
The TNC124 is a much more recent control than the TNC121 and often used to retrofit older machines. It is capable to control up to 4 axis simultaneously and has serial interface which allows copying programs from a connected PC as well as drip-feeding them. The nice thing about the Heidenhains is that this can be entirely controlled from the control (no need to initiate the transfer or the drop-feed from the PC). I would try to keep the TNC124 as it is a very capable control (in my opinion superior in most aspects compare to Mach3/4 or LinuxCNC solutions) and able to read the glass scales (which could be a challenge otherwise). Nevertheless not an easy project to add servos....
So there may be a possibility of retrofitting ballscrews and motor mounts from a scrapped MH400E?
@@greggv8 correct, but sometimes is´s even cheaper to buy a MH400E with one of the latest versions of the 432 Control. It is definitely not going to be the fastest but it´s going to be accurate and will get the job done. There is already a postprocessor for the 432control on fusion if you´d like to use this software.
“Another piece of old machinery I have absolutely no room for”
This is one of the most relatable quotes ever
How bout: I have benchtop machines scattered throughout my living room and dining area. :-O
Machine tool acquisition disorder is a harsh mistress. Some day it will be recognized for the truly debilitating illness that it is and there will be support groups and Federal funding for rehabilitation of old mills
Reminds me of a kook I knew once who was showing me pictures of old European motor bikes he had collected. Some were in his bedroom, living room, dining room. I said “let me guess, you’re not married, right “. He was offend.
Mine is "Another piece of new machinery I have absolutely no room for"
@@sicesp Many, many years ago I had a neighbor who turned one of his very large bedrooms into a woodworking studio. He also had very, very, very large (abandoned) wasp's hanging in one corner of his living room; and an authentic (working) Chinese rickshaw in the same very, very, very large living room. He was also a certified, "full-fashion knitter" in the women's nylon stocking industry. 😎👽
The big transformer thingy you were puzzled over is an inductive choke which flattens out the inductive kick caused by starting and stopping the motors. It also helps smooth the incoming power to the unit.
Damn, I know we all talk about the edit skills but something about this whole first half of the video is just smooth as all get out.
That old robot pee smell is most likely the coolant tank!
In most of the older mills, the coolant pump dies, and nobody bothers to drain the catch basin and storage tank. So like the deep fryer full of oil you put under the counter intending to use in two days and found six months later, the oil has gone rancid.
Please film the attempts to clean out the sump!
thank goodness there is no smell o vison yet, that stuff is gross, especially if it has had time outdoors to get leaf litter into the oil to provide extra growth media.
Instantly regretted inventing our Smell-o-vision :(
Now you only need a Deckel and a Gildemeister to own the full set! Gotta catch 'em all!
Millermon, gotta machine them allll
It turns out, it makes no difference what TOT does a video on, I will watch with glee.
Lol that's a slippery slope my friend... Although it looks like it's been like a year so it may be too late..
This has to become a series! Want to see whole process from choosing the parts online till the first full cnc cuts.
I spent a year back the 80’s working in a machine shop. The smell of rancid coolant congealed in the bottom of the chip tray is something you never get out of the back of your nostrils.
The smell of hydraulic fluid after a forklift got serviced was bad enough, you'll probably even be stuck smelling the stuff when you're dead.
@@absalomdraconis Heh. After a stint in network admin, I went back to the family business of earthmoving construction. I’m well acquainted with over-ripe hydraulic, and worse, sealed gearbox oil. The worst has to be the planetary final-drives of excavators… some serious anaerobic action going on in there...
@@vaalrus
Shit, just wait until a semi truck blows a wheel seal and you get to smell burnt 80-90 synthetic mixed with brake dust. Lord almighty does that ever smell horrible.
I have so much gosh darn respect for the amount of time you put into editing funny little bits into your videos, probably thing that caught my eye the most was that stuff and it being silly and with your son just makes the work you put into it so much more enjoyable to see
THanks Barreled!
@@ThisOldTony I think the fact the 'thanks' is spelt 'THanks' makes me the most happy, I got a genuine tpyo :D
This is your CNC router speaking . . . After all I’ve done for you, going the extra mile, doing things other routers would refuse to do. This is how you repay me ?!
The "P" in MH 400 P clearly stands for Pong. That's the REAL reason you made the purchase, isn't it??
@noxxi knox Why can't Tony have both?
There were no tetris models available.
Don’t touch that fräsemaschine without turning on the camera first!!!
I am so excited about that conversion project, dont wanna miss a thing!
At 6:17 it says:
The universal table is equipped with scaling function off-the-shelf, which enables you to "re-set" the zero point effortlessly.
In the dial-holder (1) and (2) are precision-dials built in, safely covered by lids (3) and (4). To change these dials, the holder needs to be removed.
Scales on the dials are tuned to "zero" by pre-tensioning with 1mm and by that you set the starting position.
This can be repeated infinitly and the accomplished accuracy is useable for most tasks.
For tasks which require the most scale accuracy we recommend set-ups according to page 3.04!
Those ceramic fuses are known as "bottle fuses", or "Diazed" & "Neozed" depending on size. They are still common on incoming mains connections in some parts of Europe, and still used in machinery in Germany. You can find the technical standards listed under IEC60269. Not that it matters if you are going to gut it of course. Looking forward to seeing more of this machine Tony!
Tony: for the last 14 years or so I have had the pleasure of, from time to time, working on / maintaining? keeping running some remarkably similar looking machines made by Deckel (the D in DMG mori). They also have Heidenhain scales but sport Hurco controls running ball screw driven axes. On rare occasion we have had to tighten the ballscrews and adjust the gibbs. After nearly 30 years of life they still can hold 2 ten thousandths over the full range of motion. That German iron is top notch stuff. Good luck with it.
Not surprising they were similar since the "M" in DMG Mori stands for Maho.
@Rickertt did you think bogy didnt watch the same video, and thats the reason he wrote that? asking for a friend..
@@bvs1q Tony mentioned that literally 2 seconds after i posted that comment, so embarrassing... To add something new: The G stands for Guildemeister, a renowned german lathe manufacturer, which acquired Deckel and Maho in 1994, became a stock company in 2002, and started a cooperation with Mori Seiki in 2004, forming the company DMG Mori AG we know today. Interestingly after the merger, the old production sites were not closed down and exist as saparate organisations within the company. They even retained much of their original specialities. Guildemeister is still producing lathes in their factory in Bielefeld Germany for example.
As an automation technician, my advise when you see a control cabinet like that is to first put the wires back in the panduit so that it looks better, then you can think more clearly to troubleshoot.

First of all turn on the electricity.
To use the Elektronik display you need to press the button at (with the orange circle) the upper right corner and than two seconds the white square button over the emergency button. If you did it right there will be standing
x-Achse,
y-Achse
z-Achse
You need to press the nc on (green) button the mashine will automaticallylIt will automatically approach the reference point x (press again nc on for y and again for z). if everything worked, there should be something in the three boxes on the right side. Press the small button in the middle with the orange circle next to the display. And there you have youre german "Fräse" . Any questions?

also Tony: [2 days later] "so I'm doing an update"

When I saw TOT scrubbing with a tooth brush I thought "This is my mill. There are many like it but this one is mine!"
The last thing I need is another project right now, I am glad you have one. Be well with the machine. Thanks for sharing. Hey 1974, that is when I got out of High school.
This looks like one of those projects that will take years. Like the MMX, project Binky or the Antikythera Mechanism.
Which would be the best we could hope for - tons of high quality content for us :-)
We're all just looking at the same content on youtube, right?
... I like this bubble youtube has created for me.
Two out of three were very familiar so I had to check out what this project Binky was about and I wasn't disappointed!
@@maikeydii Took a lot of courage for you to admit your ignorance of Project Binky. I'm proud of you, son.
We have the same Deckel-Maho milling Machine for apprentices training on work. Is still pretty much going through.
I want a whole series dedicated to the cleanup and rebuild of this!
If you are expecting a restoration, don't hold your breath.
MasterMilo restores a tank, ToT restores an ol' mill!
DMG means
Deckel ( Great Milling machine builder)
Maho ( Great Milling machine builder)
Gildemeister ( Great turning machine builder)
The MH 400 P ( P means power) is a very good and solid milling machine. You have made a good deal! Have fun with that little great machine.
Not fair! Tony has TWO euro made milling machines and I am still at zero :(
Maybe it has to do with the fact that he is not a real machinist and you are?
You can buy one for 3500€ here:
www.ebay-kleinanzeigen.de/s-anzeige/maho-mh-400-mit-tnc-135/1221618255-280-2724
But with a TNC135 it's nearly useless... and because of the weird axes drive and the vario drive for the main spindle quite hard to convert to a modern CNC machine. The Maho C, E and S ranges (most with Philips 432 controls) are better suited for a conversion.
Jan-Albert van Ree I was gonna say Old Tony should just chuck this and get a 600 with a 432 controller. If he’s a lucky old tony he can look for a Deckel FP3, would be a better choice since the horizontal spindle axis seems to confuse him 😂
Why a lowly 600? The ultimate Maho is the MH1600S, with rotary table and tilting head :)
I love watching you restore old machinery! The novelty of you making parts on new fancy machines would wear off way faster, at least for me!
I see new ToT video. Uploaded: 32 seconds ago. I click. I see 25 likes already. Video is 15 minutes long. Now that i one serious belief viewers have in the quality of the channel :)
Well, I liked after watching the video, but I've never seen a TOT video that wasn't excellent.
i always hit like on his videos first and then watch. never been disappointed with his videos.
Tony, provided that the primary and secondary windings have the same number of turns, that is an "isolation transformer" and it is exactly for the purpose of power conditioning. It is supposed to help separate harmonics and other electrical noise from the rest of the system.
Those appear to be line reactors that you bypassed - typically used for power conditioning, especially in motor drive applications where a lot of line noise (EMC) can be induced. Essentially half of a transformer, and it probably has shorts in the windings.
I don't know about 'line reactors' but my brain said 'common mode choke' when he said it wasn't a transformer.
@@Shaun.Stephens Same basic idea. Just more power (and beefier construction) than what you'd see for a common mode choke. Basically the same deal with contactor vs relay.
@@PeregrineBF Thanks. My experience is with smaller electrical and electronic gear, hence the terminology I used.
Definitely a line reactor. It's used to provide impedence between this machine and the source powering it.
And on that note, the effect of bypassing it will be potential damage to any upstream/downstream control electronics and the motors themselves. Maybe not immediately, but lifetime will be reduced; however, since most of that is already past its prime, TOT may be looking at damaging things quickly. Don't run long without proper drive components, or your motors may give up their smoke, Tony!
So much potential! Can't wait to see how this project goes!
Mr. Tony, as a german it is either a "Fräse" oder "Fräsmaschine". "Fräsemaschine" is incorrect. Thanks for attending my German language course!

I have worked on a couple of Dackel Maho machines from the early to mid 2000s in pretty extensive ways. My first comment is that some of the hydraulic pumps just sound like that. The '02 DMU 70evo I've worked on sounds almost exactly like that when the hydraulic pump runs. The hydraulic system they use only runs to build up pressure and then stops. I'd guess they did similar even back in the late 70s.
Next, all the machines I've seen have had a similar large transformer near the mains input. I think they called it a reactor. I'll have to double check the terminology in the manual/schematic. The machines I've seen have been configured for 400v wye power which is a 5-wire setup. (3 hots, a neutral, and a ground) someone at our shop unknowingly hooked one up to 480 delta (typical American power) and it caused all sorts of problems. I'm fairly knowledgeable about the machines I've worked on and I'd be happy to try to help answer any questions you may run into. Nice solid machine you have there. Good luck with it.
(also, don't be afraid to contact DMG-Mori about the machine. You might be surprised that they still have info on it. Those Germans tend to be good like that.)
Thanks Justin! This machine doesn't seem to do a think unless the hydraulics are running. I've waited to see if it would build pressure and stop, but it just keeps on truck'n.
After seeing your second video with first chips I totally see what you mean. It probably has something to do with the hydraulic axis drive activation. It looks like you're making great progress.
if you want retrofit it, i have programmed a full config for it. And my mill is clean (after 4 weeks of cleaning ;))
I hope he is going to read that
the vogel oil pumps are really good at what they do. on the down side parts are expensive but they are still all available skf bought them out but kept the design the same. hope you enjoy working on 70's era German machines as much as I do its always interesting and a little different.
"I've got pedigree on my hands"...better wash them real well!
Awesome! Definitely a cool multi-part series in the making. How you disassemble, clean, and refurbish/convert it. I cant wait.

Well, the German A is kinda pronounced like the A "carbon" or in "ah", or in "start". The O is pronounced like the O in "bomb", or "core". So it's probably not "Meyhou", but "Mahoh".
And they don't do a lot to the pronunciation. For example, the O in English sometimes becomes Ou, usually when the O is at the end of a word (btw. the O in "word" is like the German "ö").
Like, the O in "more" is a different sound than it is in "hello" some words even have both versions, like "robot". In German that's not a thing, at least not to that degree.
In an open syllable the a becomes strong(long), like in "ha ha ha" the same for the O, Like the O in Santa's "Ho Ho Ho". Besides that if after a vowel comes an H the vowel is pronounced in its strong(long) form by default in German.
I just realized how ridiculous the word "robot" must be to non-native English speakers.
@@naota3k But you do know, that it´s of russian origin?
@@naota3k Here is some more weird stuff:
"row" ou sound

Guess there is a reason why people study linguistics.
@@raudi42 I did not.
Small tip: when re-inserting the tool holder into the spindle, give it a quick wipe. This will prevent embedding chips, dirt, etc. into the holder and/or spindle. Or so I've read. :-) Thumbs up to crush a troll.
MAHO is good, too bad myhoe doesn't let me buy that kind of stuff
LMAO
Expert here: the secret is not asking before buying...
It's easier to gain forgiveness than it is permission. 😉
When asked did you just get this? The answer is always no, why do you ask? I've had it a long time. As the semi is pulling out of drive way and I'm taking selfies with the new tool.
@@tysleight lmao I just pulled that trick this past weekend, "yeah I've had that thing for months baby, I got it before summer started even" It works 60% of the time, everytime.
Thanks for making me feel better, I just got over the flu. Yesterday my thermostat went out. So I went to local hardware store (small town ks, i mean really small, the kind of small were they teach hunter safety course at the Jr high). Anywho bought the thermostat got it home, come to find out I have a 2 stage thermostat. I was freaking over that wiring, 7 of them. Color coded, I did wright it all down. So I ordered the correct one. The reason for freaking out it's supposed to freeze tonight. The part were you made me feel better is when you opened the electrical panel on your new machine 😁, suddenly my 7 wire 2 stage thermostat wasnt so bad. Feel better.
PSA.check the batteries in your memory thermostat, because a leaking battery will eat the electronics. Smoke detectors, check the air in your tires, test the coolant in the vehicles....

I’ve just retired after a couple of decades of working on CNC machines.
You should see the inside of the electrical cabinet on some of the five axis machines I’ve worked on.
Pucker factor is intense. 😂
The spindle looks like a 40 taper and the ones I’ve seen always use air to push down the drawbar against a big honking spring.
I’ve seen hydraulics used on the bigger 50 taper ones.
It should not be hard to convert to air.
One axis at a time!
I’ve never seen one quite that primitive but it’s kind of cool.
The downside is G3 ain’t gonna work.
This is going to be an interesting project and I can’t wait for the next episode. ❤️
This old Tony I have confidence in you that you can fix this in a winter. Did I mention it was going to take you 12 winters.
A winter, some winter, same winter. Schedule met.
Good luck with rebuilding/improving your new machine!
Having an isolation transformer on the input of a German machine is pretty typical, just be careful because if you lose power, you'll lose a lot of info as the computer won't have time to react.
he said he's gutting the old electronics, pay attention.
@@dimitar4y yeah, I jumped the gun a bit, still relevant information on any CNC though. I run into this issue a lot at my current place of work.
@@geraldgepes You must be at a crappy budget place with an asshole of a boss. Every CNC place I've applied to work, and had broken down machines, I've gotten mysterious sacked for asking about the broken down machines. It's like being in a house with an abusive drug-dependent alcoholic father. He thinks he has to stay dom/alpha and beat up anyone who "looks at him funny" or points out his "mistakes". Shops like this produce crappy parts that get people killed on a daily basis. Except the companies that buy are too dumb to sue.
@@andrewyork3869 Who's throwing away a fine machine? Tony's gutting the old electronics because he wants to update its CNC capabilities to simultaneous 3 Axis work (potentially 5 axis in the future) with ability to read GCode off USB/Drives. The current one is damaged in unknown ways, and is only 1.5D milling. Seriously, are you drunk or did you just woke up?
@kerryithm2 The current system uses proprietary hardware with RAM chips that keep the data on them, with no programming to offload it AFAIK. You'd have to install a UPS to keep it powered, and add in a botch wire to pause the program if the power gets cut off to the machine. Unless the manual talks of a hidden backup feature. Modern machine control panels, I think, should have auto-backups, and on re-powering it'll require an operator to review before resume. Community made CNC projects don't back it up though. USB cables aren't very good at noise absorbtion, and those motors are pretty noisy (electrically). 3D Printers getting their code on USB wire can get crashed by a single motor running in the adjacent room. Even a tiny dremel.

I have worked on simmilar machines with the same Software (Haidenhain) and have repaired almost all of them at some point. Whenever you have a Question about this Machine, kontackt me. I am glad to help
I am currently working on the conversion of a MH400C, looking forward to see your progress. I recommend you check your spindle bearing before doing anything else. The top bearing is unseal which mean everything entering the cone can fall in the bearing. Also, the outer race is the spindle housing itself making the bearing replacement nearly impossible. I also have about 5 set of manual if you are interested. I am doing a full replacement of the electronic, if you need any part, let me know.
If I were you, I would put the CNC motors where the handlebars now sit... change the spindles, so it is easier to install and scrap the old controls... that would be my conversion!
Thanks Tony. When this video was first released I went right out to Ebay and started looking for a CNC mill. I had a decent mill drill, but I was ready to step up to a full size vertical mill. I ruled out CNC pretty quickly, but I did find a nice old Gorton Mastermil that had spent the last 60 years working at Allen Bradley in Milwaukee. I am now the proud second owner of a 60 year old mill, and for my wife's sake, it's your fault.
Oh c’mon This Old Tony, everybody needs a hug!!
I once worked on a system that included some hydraulics. The hydraulic power supply used to make a noise like yours - it was the pressure relief valve. The hydraulic pump is a constant volume device so enough fluid flows until the output power equals the input power. If you block off all the pump outputs then the pressure can rise high enough to stretch the bolts. Hence the inclusion of the relief valve. My understanding (I'm NOT an expert) is that you can design the hydraulic system two ways. The noisy way is that the load impedance is sufficiently high for the pressure relief valve to be continuously open, not very efficient. The quiet way is that the required energy can be delivered to the actual load(s) at pressure less than that at which the relief valve opens. Like I said, I'm NOT an expert so I'll be watching the comments.
Good to know I'm not the only sucker who buys broken machines thinking I'll fix em up.
Dear Tony, you have huge meatballs! As the new owner of a used Boyer-Schultz H618 surface Grinder ($200 on craigslist) I am well aware of the fun that you have just purchased. I will say that "I have serious cast iron bed envy". That X-Y table is totally awesome and possibly worth what you paid for the machine. Also, for those not familiar with precision measuring equipment, Heidenheim is the very definition of "precision". Those glass scales are probably also worth what you paid for the machine. I wish you all the luck in the world with your project, you might need it. When things look overwhelming, just remember.... how do you eat an elephant? One bite at a time!
I see Tony is still holding onto AL’s wire brush!!! 😐
Richard Cunningham I thought perhaps his real name is Anthony L..., but then I realised that it’s a aluminium wire brush so it’s for use on aluminium parts. I almost got well distracted by this in the last video.
Nice throwback for me! I actually learned milling on one of these in my trainee time here in Germany in the early 00's.
I love how you pronounce Phrasemachine ehhhh Fräsemaschine! Made my day (as always)!
Those drawings are delightful. I started work on a modification to a 1950s aircraft and have always an affinity with the dying trade of engineering drawing ever since.
Yea, Maho Fräsmaschinen are the best.
I'm from Germany I leaned milling on a Maho MH 800
Careful, Tony! CNC machines are more dangerous in packs! Best keep your CNC router on the other side of the room lest they start to work together to enslave humanity😏.
"I'm no electrolycist..." You are to me, Mr. Old Tony. Thanks for another video of chuckles :) When are you bringing the family to vacation in New Mexico? Las Cruces has a retro-cade... maybe with a Pac-Man... I owe you a soda.
I've been rewatching all of the old this old Tony videos this week. So the fact there is a new one is blowing my mind
Don’t get me wrong, while I love seeing the notification that you have a new video up, it’s not cool when it’s a workday and I’m stuck at work and can’t watch it right away!
It is called Delayed Gratification!
Dear ToT. I explativeing love you. I lament the fact that you can not produce videos hourly. I hang on the hook on the end of every episode gazing forward to the horizon of the next. This stuff is pure and awesome.
Are you done yet? this is exciting!
Hey, just wanted to tell you that the big "transformer" is a choke! it indeed does power conditioning of sorts, it reduces electromagnetic emissions. You might want to find a new one with the same inductance and power rating to replace it.
Alec Steele: 24 part series of Cavalry Sabre
TOT: Hold my beer.. 54 part series on mill conversion
Me: Bring it on!!!
And Wintergatan is best with Episode 97 of his Marble Machine X
I got hooked on this channel a while back partly cause I have done some of the same sort of things but it is really the narrative that keeps me coming back.
I would really like to see the teardown process.
I have seen a few tape drive CNC machines upgraded to modern CNC controls.
They looked like good setups to me. So I look forward watching this getting worked on.
1:10 pronounciation is an A for "At least you tried!".
No, that is not correct. TOT pronounces it correctly at 1:10, as a matter of fact.
@@kris7822 no. Lost the "e" in "Fräse".
@@kris7822 I'm a huge fan, but you're just wrong. Anyway, I'm sure the point wasn't to nail the pronunciation. To hear the correct pronunciation, try ruclips.net/video/0Ae9568ggkE/видео.html for example. (Mit bonus Ostdeutsches Akzent ;-] )
Edit: Acutally, that's a pretty cool channel too. @talla83 - ich habe gerade abonniert!
@@L00S3H3AD Fräsmaschine ist richtig, niemand sagt/schreibt Fräs>e
@@3LFL3DA Hello from Germany. He pronounced the word right, but spelled it wrong. ;) Also, Heidenhain is pronounced [Hydenhyne]. But, so far, so good. 8o)
Yet again a video worth watching (y) . Thanks ToT - You are closing up on being watched over one million times - that numbers is incredible! Keep em coming! Love this channel (y)
To move the Z achses pull on the spindel to engage.
I have worked on german milling machines
Ist ziemlich nervig aber stimmt. Die älteren dreh- und Fräsmaschinen haben das als Sicherheitsvorrichtung. Aber ich denke das hat er schon ausprobiert
Please elaborate.
@@ThisOldTony He means that you have to either push or pull the handwheel in, in order to engage it. Some Schaublins and Deckels have this system as well in order to prevent accidents in CNC mode while the machine is running.
DIY Dilettante . This also true for an old Deckel FP3. Pull the hand wheel gently, while you spin it. At some point it will engage and start moving the spindel.
Awesome!
We had two of those machines at school, fully functioning only with the Philips controls instead of heidenhain.
You need to pull the x, y, and z wheels and then turn them. It's a savety mechanism.
I would LOVE to see you do updates as you get ideas/change things on this old freezeray! Even if they're short and rambly, even if they're super far and few between.
Normally if you try to make a Venn Diagram of "Automatic oilers that work" and "Automatic oilers that have oil in them", you'll be lucky to find anything in the intersection...
Which of course makes it an Euler Diagram.
Looks very similar to the zayer mills made over in Spain. They use the same feed motor system. One motor that can reverse direction and ramp up and down for feedrates, then 3 clutches to power individual axis.
Looks like a fun project to turn it into full cnc!
Maho:s r exelent ,real high quality stuff-now please do a real long and nice restoration/rebuilding-vid..i love those
He is not going to do a "restoration/rebuilding". It was clear in the video that he intends to use this as a base and build something modern and useful.
It's an isolation transformer we use them frequently. They're used to smooth out the power among a few other benefits.
Wednesday just got a whole lot better, thanks for the upload!
More then half, if not all, of what you have planned for your new toy is way above my comprehension. But that has yet to stop me from watching anything you have ever posted on your chanel. Thanks for what you do, even if I don't understand what's going on sometimes I keep watching, and rewatching, and rewatching. You make learning fun.
Did any of you guys see the DMG stand at EMO this year? It was a whole hall with dozens and dozens of the most amazing machines that I have ever seen. I nearly went off women...
