Great gift , I love it , Awesome job on the setup Lee ! ENJOYED ..
This is very timely for me, I have what looks like the same kit to install on my lathe. The programming is a big help also! Thanks!
Perfect timing for me to find this video! Just got a PM 1236 and have been scratching my head on how to get DROs installed - this is a great solution - thanks!
How's the PM treating you? Looking to get one myself
At first the DRO for the carriage was questionable to me but after seeing others putting on their machines, I now see and understand your logic. Very good video I will refer to this video in the future when I do mine.
Good deal on the DRO. Nice new setup.
I used your installation method on my PM1022-vl lathe. The DRO works fine and the added space behind my lathe is nice. Thank You!
My DRO just came in. Your videos will help me install mine. Its not the same , but similar.
Thanks Lee,
I bought two DRO setups some years ago. Fitted one to my mill and chickened on the lathe, for your stated reasons. My lathe is bigger, but same issues. I will PM you my work arounds so you can share. Just don't hold your breath. My retirement is on hold due to work commitments.
I like your "CAD". Thanks for sharing the install. I have a mini-version of the same lathe and am looking to mount a DRO. I was looking at the Touch DRO but I think I am going in this direction instead. Thanks again.
Thanks for the video I'm going to do this, my lathe is same under another brand, I like the extended guard I have access at rear ,so I'm fitting a bin bag to catch the chips,a round hole with two hooks & the chips can go straight in, from Coventry UK.
Beautiful Install! Neat and well thought out!!!! Thanks for sharing!!!!!
i really like your X axis solution for the DRO mount.
Definitely pragmatic. This solution is excellent for anyone with ample space to accommodate these kinds modifications. Many hobbyists lack the space. That said, once again excellent video and presentation.
A really interesting video, very well made thank you.
Was just thinking about doing this to my Grizzly. Appreciate the walk through on it.
Thats awesome! Congratulations on the generous viewer mail
This makes sense for the mini-lathe I have too, thank you for the idea and the explanation.
Bonsoir. Je suis français et je regarde votre chaîne , malheureusement ne parle pas anglais , mais vous m’avez super bien aidé par vos images pour la fixation de l’axe X . Je fait pareil que vous . Cordialement . Dominique
I need viewers like that.....🤣. Thanks for sharing. Your videos are great quality and well thought out.

Brilliant video, great info. Thank you.
Bonjour, j'ai le même tour, cette solution pour installer un DRO est la meilleur, on ne perd pas de course longitudinale.👍👍
great video, thanks for putting this up, hoping to do this on my emco, (upcoming birthday permitting ;-),
All the best,
Cliff
I have the absolute same lathe but in Europe its sold under another name and i bought a Sino DRO with the lathe and am very satisfied with it... In future i only use glas scales with a good DRO nothing else because even the other things cost quite a lot of money but you never get that comfort and accuracy out of them.
Thanks Hank, this was a really great video. Say you wouldnt happen to know anything about propane or propane accessories?
Love the setup. Personally I’d like the space created for chip removal that is my gripe with my G750G. Cleaning out chips
Pretty cool, and a nice job installing it. Surely you can set the distance from/to center for all your tools.
multiHappyHacker Yes, up to 200 Tools.
Thank you very much for your time on teaching us, I do really that good heart, hope in the future I will buy a Grizzly G0602, like wise a Mil G0704, like you accent, thank you again God Bless you, hola from Mexico... Fernando
nice unit and setup
I couldn't get rid of the 5th decimal place on my dro so I just covered it up with black electrical tape.
Cool work 👍
I think the scale setting is 5 microns per step on the scale, in accordance with how the internal divisions it was manufactured with are. Five microns is a little under 2 "tenths".
your lathe the 1128 is a nicely lathe for the home 😀
Thanks Lee,
I very much enjoyed your video on installing the DRO in a way I had not thought of doing. I am interested in your tool holding rack that's mounted on your chip shield. I looked at your available videos and didn't see any about the process you went through to build your rack. Do you have anything that shows the rack in more detail?
A nice project I have on my list. One question would a taper attachment interfere with mounting the scales? I like seeing a great variety of installs as each presenter goes over the pros and cons of where to mount the unit with his setup. So in no way should you feel like it has all been done or overdone. Seems each is very different and has lots of good information to consider. Take care. Doug
If you want to be really picky on getting the scale pretty much exactly parallel to the lathe bed, could use a couple of 1-2-3 (or 2-4-6) blocks as spacers That way you could put the scale at 1inch down or 2inhes down with very little hassle if that spacing would work for you

Great price on the new DRO. lol Great work on the installation. Can come back to this, and others, when/if I install one on mine.
Most Pragmatic explanation going especially making things in English :)
Its from banggood. I just ordered the same except for a 1000mm reader for my lathe.
Thanks for this video. Just purchased a PM lathe and a DRO to install. I have shamelessly copied your install - really like the way you set the cross slide DRO. I have a I-Gaging DRO for the tailstock too. I cannot see how you've attached it though. It doesn't appear to measure all the time? you can attach it at will? Thanking you in advance, AndyH
Installed the DRO Z axis in front under the lead screw and after the feed rod, just to be different.
Hey Lee I’m getting ready to install a this same DRO brand 3 axis on a Bridgeport and I was watching this video to see how much clearance you put between the reader head and the scale but you audio was garbled and I could not make out what you said. Did you set it to a certain clearance? As you know the reader from the factory is held in place with zip ties and when the ties are cut the reader can move from tight against the scale to about 1/4 movement. What clearance would you recommend? Also I thought that I had watched one of your videos where you installed this same dro with 3 axis on your Mill. I looked but could not fine that video, am I dreaming or did you make one? Thanks for these videos they certainly have helped me.
Hello, MISTER LEE. Dose it matter what end you put the reader at. As of right now on the Y axis I put my reader not bye the table. Is there any reason I should not mount it this way. Thanks for the video's.
Would you happen to know how to change the linear compensation. I did what it says in the instructions and it does not change a thing
I think I can mount a DRO on my South bend lathe like you have done. My 70 year old eyes have a hard time reading the graduations on the dials
This is Keith from Michigan. I happened to run into as of March 28, 2021. I'm extremely interested with the PM1127VF Lathe, and wanted your opinion, since you have been using it. I'd like your response
great work - but guess I have the mill attachment - its not going to work for me.
I got the same lathe but with a milling head so I guess I can forget about this. Maybe go with two of those small caliper scales instead.
My unit will no longer power on after very little use. It has 120 VACr and a good fuse. Where do I get it serviced or get a schematic or service info?
I might of missed something somewhere, but when you moved in ,106, it seems to me it would take off .212 and make it too small to get to .625 from .731
Great channel and watch your videos like clockwork.
You might have changed the setting by the time I write this, but i noticed when you started the DRO it was still in MILL3 mode. For your setup and from my own experience with the chinese software it should be in LATHE2 mode. This can be set via the device mode menu which is normally different from the settings menu - check your manual on how to access it.
Setting the correct mode will enable the lathe specific functions like diameter and radius reading, taper measurement and tool library. Re the diameter and radius reading on the cross slide, that is normally accessible via a lathe function button on the DRO once in lathe mode, on my DRO I push the 1/2 button to switch between diameter and radius reading. You should not need to change the scales resolution setting from 5 to 10 microns to fudge that. Here is a video of what the diam and radius function reading typically looks like.

Cheers,
James.
James Walker Thanks - I will definitely look for those settings!
Hopefully your manual will be clearer than mine was and more importantly - correct. On my DRO I have to quickly push the M/I key 6 times while the DRO is going through its start up sequence. i.e. when you power on and the display cycles through a set of numbers and text. Of course the manual said to push a DIFFERENT key. Anyway, if you get into the setup menu and have a fight with what settings to use let me know. I've already had that fight and I suspect the underlying firmware is probably the same for the bulk of these chinese sourced DROs.
Cheers,
James.
Right! the trick is to press that button 6 times while the numbers are flashing by, not before. It took me a while to figure that one out.
James & George - Thank you, thank you, thank you. I would have never guessed that pressing the M/I key 6 times during startup would allow me into options that aren't even shown in the documentation. And the 1/2 key got me set up for diameter without having to fudge on the resolution. I'll look around more at what's available in this menu and will publish and updated video soon, of course giving you guys credit. Thanks again!!!
@@jameswalker8338 Hi james, i have the GCS 9002d on my lathe but the 1/2 key just does 1/2. I can get into the normal setup menu using the password as in the book but cannot find the hidden menu to select radius/diameter, i suspect my dro is setup for mill and not a lathe and cannot find the way to change it so the funny sybol does not appear when i press 1/2., I tricked mine using linear compensation to make it read the diameter by dividing the observrd distance by 2 so it thinks its moving short works but its not ideal for on the fly changing. TIA.
cardboard assisted design..love it
Confused as to why you refer to the cross slide as the Z axis? Surely the Z axis on a mill is up and down, the cross slide should be the Y axis?
Thanks for the education Mr Lee, shame about the audio.
You should be able to transfer your calculator results (0.106") directly to the 'X' screen by touching the '
Surely the Z axis is from God the the Devil? Left to right is X axis and to & from your body is the Y axis
Just for info. The Z axis is always the axis of the spindle. (no matter the kind of machine). So on a lathe it is the left to right horizontal axis (or the vertical axis on a vertical mill). The X axis is the longest axis that is not Z. So that would be the cross slide axis on a lathe. Hope it helps
I put the measured dimension in the dro then you dont have to do any math you just turn to diameter your eg was .731" so punch that number in then turn till its .625 and done
So would I.
This is why the directions of the readouts are not the right way round as Lee set them up.
As shown, as you reduce the real diameter, the dimension would increase!
That's how I do my X too, entering the present diameter that is, but I like my Z to read positive as I go to the chuck to give the length of the piece. To each his own.
Interesting. To me, your axis directions are both backwards. Guess its just personal preference
Why do you want Z go positive towards the chuck? You start from 0 and go negative towards the chuck, that is the common way to do your lathe work you take away material.
Just my 2 cents
Cheers from Sweden

Enjoyed the video. I appreciate that there are many ways to skin a cat and mine is to measure my stock, touch off and put the stock dimension in X, then turn down close to my finished diameter, measure and again input that in X and turn to the finished dimension, so all the time my diameter is reducing. I'm also with bsjoelund on the negative Z on a DRO.
It's about what works for you, in your shop.
Food video, and a great gift. However, concerning you iGaging scale issEe, check out the scales Yuri recommends, the AccuRemote scales. Basically the same specs as the iGaging, but much more robust and better build quality If the scales on the mill act up. They ARE more expensive than the iGaging, but if replacing the iGaging just once, the price works out about the same. And they are totally compatible with the BluDRO unit

Think you got some coolant in your microphone, just kidding.
