I would like to add one safety comment. When I served my apprenticeship as a Scientific Instrument Maker completed about 51 years ago, it was hammered into me that one NEVER wears gloves when using machine tools. I believe this is very sound advice because if the material of a glove gets caught up by the cutter, one's hand can be dragged into the cutter resulting in massive injuries and disablement. If one doesn't wear gloves, contact with the cutter (which good practice should avoid anyway) would result in a much less severe injury.
I recently was being foolish on a bench grinder on a small part without pliers, and the rests were way too far away from the wheel. I luckily only lost some fingernail, but if I had been wearing gloves, it would have been a trip to the hospital.
that's what we used to do back 50 plus years back then, but after being 79 I now use latex to cover my hands to keep dirt and grease off them
It's nice having clean hands to work with
Never Use Gloves or Long Sleeves! I was never trained, but I've had a home shop for decades and spend hundreds of hours working around all kinds of stationary tools. I had a terrible experience with my RF31 mill-drill. I was drilling holes in wood and my tight fitting fabric glove got caught somehow. In an instant, hand was wrapping around the bit and actually stopped the machine. I was SO LUCKY I had the belts set for low torque and that I wasn't using something like a fly-cutter or my hand would have broken or mangled beyond repair.... I agree that nitrile gloves are good.
I've been tempted to try one of import DROs for budget reasons. Thanks for sharing the install and packing method. Glad it worked out for you.
Thanks for watching
I've had my lathe Harrison M300, for 15+ years by now. Bought it installed with a Fagor 3-axis DRO (several years old allready then) It has been great though a little old fashion with very few extras. When it broke down last fall I could have replaced just the central unit for about £600 and kept the scales. No one knows how long the old scales would last. So for one or another reason I decided to replace it all with this £200+ Chinese. After using it for some weeks by now I'm very pleased. Fairly easy to install and operate and many of the gadgets are very helpful. I no longer need to manually enter new indices every time I change tools and the built in calculator is useful. Though, I have had one "little" problem so far: The top slide scale is a few millimeters too high to fit so I havn't been able to install it yet. I can live with DRO on just 2-axis but will give it another try sometime when thumbs twiddling is getting too booooring (meaning, I've got a couple hours left:)
I agree about it’s ease and versatility. Especially, the price! Maybe, when I grow up, I’ll install one on my lathe, too :)
Cheers.
Thank you for the entertaining and informative video. There are several valid comments concerning gloves and your safety.
I appreciate your courtesy and thank you for watching.
great milling machine!
I just bought a very similar set up for my drill mill
Have a mini mill that am installing glass scales as well and have been watching vids to borrow / steal ideas and I find it funny that everyone that I have seen uses a mill to make the brackets I stripped mine down completely to get the packing grease out and off and check for burrs etc. and while its apart should be easier to drill and tap mounting holes for the goodies that I can't make on the mill because it is in pieces lol
I actually didn’t watch others install readouts, honestly! I don’t claim to be an original, either. I just went with the metal..
Cheers.
Same boat, different water here. My mini mill is nut and bolt apart right now. Guess I'ma put it back together to attach the scales, cut a belt drive and some flying buttresses.
This video was very helpful
Alise Darsch I’m glad you enjoyed it.
Cheers!
I got the two axis DRO for my mill,however, they did not send any instructions as to how to secure the scales to the mill. thanks to your video I can make my own now.
You are very welcome! Thanks for watching!
If you're going to be power tapping, try using a spiral point tap. MUCH better than a hand tap.
Good point, thanks. Maybe, when I grow up, I’ll get myself spiral point taps. Thanks for watching.
Wobble, wobble, snap!
Why didn't you use a new drill bit ?
Free-hand power-tapping a small tap in confined spaces with a rechargeable battery drill is just begging and pleading for trouble.
It’s a good point and I understand that. However, it is something I successfully been doing at work for years, using brand name taps. These Chinese taps just crumble down. By the way, never buy center drills from China, either! Those things don’t even last long enough for me to say how much they suck!
I agree. It was painful to watch! Breaking off a tap in a machine tool is a crime. I would have hand tapped and used a tap block to square the tap to the machined surface.
That's what the clutch is for on the battery drill. It is an accepted industry standard nowadays.
@@union310 Taps break when you bend them . The finest limited slip clutch known to man will not stop you from leaning sideways on the drill.
@@agwhitaker I tap hundreds of holes a day with one for living
Got almost the same DRO kit from China like a year ago. Are your scales with rs232 or TTL interface?
The description says TTL.
Btw, how is your DRO working out for you? Could you make use of included brackets? Thanks
Tinkering Nerd DRO is really helpful and yes, brackets are subjects for processing
I have a question, I bought the same one except two buttons have Chinese characters on them. The one is the red button in the bottom right corner. What is that? The other is the blue button in the upper right corner. What does that read on yours? Thanks.
Bottom right red button says “ENT” (my best guess is for “enter”)
The upper right blue button is calculator function.
Thank you.
Helpful video - thanks. My DRO arrived with readout manual but no installation instructions like your did. I hope I can find how you mounted the Z axis since this video is now two years old. (I did subscribe.) Don't let the negative comments get to you.
Thank you for watching and subbing. I still haven’t gotten around to the z-axis scale. Hopefully, I will do it this year. Stay tuned
Nice, informative video. But I would keep the plastic cover on the head unit.
G'day I found it really interesting how you went about fitting the two axis to your mill. I have the same DRO waiting to be fitted on so I am interested to see how other machinist do it, are the cap head bolts M6 and I would really appreciate the size tap and drill you used it would be a great help I have subscribed thank you John Tasmania Australia
Hi, thank you for watching and subscribing! I believe I used M6 bolts where brackets meet with the machine. Other included bolts used to attach scales to brackets. Tapping is easy with metric system: for example, M6x1 means 6mm diameter, 1mm step per turn; drill size is diameter minus step, 5mm in this case. Works for all metric tap sizes.
Thanks again, cheers.
Tinkering Nerd thank you for replying back to me it is greatly appreciated kind regards John
Hi John, interesting that you are writing from Tasmania, Australia. So am I! And I'm here for exactly the same reason. I just picked up a 3 axis DRO for my vertical PAL mill and was looking for any hints and tips. Your message is a year old now, so I guess you have completed your installation? Any hiccups? I'll be tackling mine in the next week or two - spare time permitting. Cheers, Craig (10 mins from Hobart)
Craig's Workshop G'day Craig that particular mill I sold it was a SIEG and I wasn't happy with their after sales service and on one occasion they sent me wrong parts and didn't know their own machines. However the DRO was pretty easy to fit I just mad a couple of brackets, my mill is HM 46 regards John
Thanks for a very nice and instructive video. I just got my DRO and am in the process of installing it on my lathe. Looks identical to yours. Everything seems straight forward except what vertical play to chose between the glass scale and it's pickup? The only document that came with the system was a user manual. No installation manual. How did you do it?
Thanks for watching. I believe internal construction of the glass scale will allow for some play/misalignment between the body of the scale and the slider. During my installation, I tried to set the slider as parallel to the body of scale as possible, at a distance of about 1mm between them. Hope it helps.
Cheers.
Hey thanks for the video ! i got the same scales ! they say in another video that you should use the red block to place correctly the sensor regarding to the scale... the regl block should be able to slide in and out without effort. Also they said this red block should be left in place to the last moment. Also i didn't saw any cover for the scales in this video, did you use them ?
I didn’t see no blocks when unpacked the scales, maybe I missed it? :)
Yes, I used supplied aluminum covers. Process is the same: mark, punch, drill tap, don’t cuss.. Two holes for short cover, three for a long one.
Thanks for watching!
@@TinkeringNerd hi the red blocks maintains the sensors on the scale. you see them often with scale images from google. m.indiamart.com/proddetail.php?i=11711251348
Hmm.. the scales I received had no such thing. Maybe because I got the cheapest ones?! No real surprise here :)
ВЫ точно коллега- у Вас как и у меня есть фрезерный станок, могу с Вами поделиться наблюдением из жизни, сверлить чугун лучше с маслом если это помогает, иногда хорошо сверлиться и без масла, видимо зависит от марки чугуна. Резьбу я давно режу без масла, но при этом обязательно выдуваю стружку в виде порошка каждые 3-4 оборота, когда резу резьбу например М12-М14 каждые 2-3 оборота. Это исключительно мой опыт.
У меня есть ещё и токарный станок, и два сварочных аппарата. Я рад, что есть люди как Вы, которые разделяют мои интересы. Когда куплю себе метчики хорошего качества, тогда резьбу нарезать будет одно удовольствие. А пока использую то что есть.
@@TinkeringNerd коллега метчики хорошего качества это песня.
Купил себе 2 набора Guhring один набор для сквозных и один набор для глухих отверстий.
У меня нет слов от удовольствия работать этими метчиками
Nice video! Did you install the Z-axis yet? How is the DRO working for you?
Thanks! It’s been little hectic, lately. Didn’t spend much of the summer in the shop, at all! But, I installed new garage heater, hopefully, will be able to resume all my projects, including z-axis scale. I also want to put a separate quill DRO. Stay tuned..
@@TinkeringNerd I'd like to see how you mounted the Z as well. Thanks for posting this first part. Very helpful.
Using gloves around moving tools is a good way to lose fingers!!! Other than that very good and informative video.
Did you use a wood cutting blade to cut an aluminum bracket? Hardly the brackets fault, use the right tool for the job...
Thanks for the comment! The blade says wood + soft metals.
Thanks for the video. How happy are you with this DRO?
Hi, and thanks for watching! This DRO is working satisfactory. It may not hold up in full blown industrial environment, but for a home shop it is a steal! Soon, I have a plan to explore some of its advanced features, stay tuned.
Cheers
After using this DRO for 3-years, are you happy with your purchase? Would you buy the same DRO again?
Wow! Has is been three years? Well, I haven’t used it this whole time, few hours here and there. But, it’s working just fine, no problems so far.
@@TinkeringNerd Awesome....thank you!
Seen that broken tap coming.
Yeah! Lol
Yes, don't use a drill to drive taps, and - do not use tapping fluid when tapping cast iron, fluid stops the fine cast iron cuttings falling out of the hole.
They shipped it with FedEx.... and Draw UPS on it.....
Здравствуйте!
Интересный ролик! Спасибо!
Ещё Вы чётко произносите каждое слово, интересно кто вы по национальности.
Я из Владивостока.
Спасибо за доброе слово. Мы с Вами земляки по планете.
Всех благ!
Cast iron is supposed to be drilled and tapped dry. Fyi.
It depends on the type or hardness of the casting.

Hi, it looks Great so far. But you shouldn’t wear Gloves around these Machines. That’s a quick way to really mess up your Hand, Arm, or lose your Life.
The interesting thing to me about the human bean is that we demand the cheapest devices that the world can produce, and then we bitch about the quality of the hardware often times complaining about things that don't even matter, like for example the fact that the D-shell connectors come with plastic housings. I'll assume that cutting the aluminum brackets in a wood cutting mitre saw was comic relief although I know many who use woodworking saws and tools to cut aluminum. If it's for real and not a joke I have zero sympathy.
Who's enough, and why is it good?
Cosine error is always a concern when measuring, so minimal runout will reduce that kind of error (measuring what is in essence a hypotenuse instead of the adjacent angle). A few thou is nothing in this regard over the span of a couple or three feet of range. Personally I would be more concerned about the accuracy of the scale itself to begin with than a cosine error on a long scale, although there's a reasonable limit.
I shook my head when the tap was broken off by running it in the cordless drill. This is easily done with the highest quality taps made in Germany, or the USA. It's operator error, not the fault of China (I'm not defending Chinese products, but please, let's focus the error to the correct cause, and of course there we go again, buying the cheaper products and then complaining about the quality).
Thank you for your input. I do cut aluminum on a regular basis using miter saw with special aluminum cutting blade.
About cheap stuff though... have you heard about latest trend towards planned obsolescence? So, there is no real good quality stuff anymore. Back in the olden days, things and tools were made to last, then few decades ago, manufacturers came up with “heavy duty” concept where if you buy heavy duty item, you expect it to last a long time. Now, they provide lifetime warranty for some things and the lifetime of an item is very finite, sometimes as short as 6 months. So, we’re screwed no matter how you look at it.
Cheers.
Why do people have to always put stupid music on their videos when it is definitely not required
You must love watching videos from some Indian tech channels.. lol
@@TinkeringNerd Not a chance!
Better to keep ones mind unpolluted.
@@CMAenergy my newer videos don’t have music. Well, except for shorts. Cheers
Drill Doctor? You'll need a real doctor if you keep wearing those gloves while grinding. Am I wrong? Anyone?
I know, you've been wearing gloves for years. You've never had any problems.
Some old man has got nothing better to do than pick on you.
I know. I get it. It's cold in your workshop.
It won't hurt this time. You'll be extra careful.
Hand on my heart, I wish you the very best.
I wish you not to get you glove pulled into that grinder. Your hand's in it!
Please, don't wear gloves.
No gloves. No rings. No watches. No nothing. And...roll up your sleeves.
God bless you.
Thank you for sound advice! Since that video was posted, I installed a natural gas heater in the garage. No more gloves!
Cheers.
"Made in a basement in China" If you criticize someone, have facts, not imagination. Normal human decency. Especially when it appears you don't understand how to make good threads, and can not make a simple cut in an aluminium bracket,
Thanks for watching
The fact that I decided to include my failures in the video is not indicative of my incompetence. It merely has a demonstrative purpose to make a point that Chinese taps are not worth the money. I’ve been drilling and tapping for about 25 years and these Chinese taps that I broke in last few months account to almost half of all broken taps in my lifetime. Similar story with aluminum: just because I couldn’t cut that piece doesn’t mean I don’t know how to cut it, it means that the piece was too soft, thus, even if it did cut ok, I wouldn’t want it on my machine, anyway.
Again, thanks for watching and commenting,
Cheers
@@TinkeringNerd I enjoyed the video for its information and especially enjoyed your humor. "Ya can't please everyone so ya got to please yourself."
