Hi Frank nice to watch from you this video. Nice to have one on our lathe as well we added it to the DRO last we were a bit lazy when we initially installed the DRO, DRO installed never looking back now we are spoiled.
Thank you for sharing this very clean kit made to be installed with ease we are sure.
Lance & Patrick.
Welcome back, Mr Hoose! Thanks for your videos.
I just finished installing my LMS Tailstock DRO on my LMS HiTorque bench lathe.
I encountered two problems in fitting, but we are machinists after all, so no big deal.
The 4 bolt pattern of the part that attaches to the tailstock was drilled with a slightly smaller spacing between the holes. I measured my lathe and found the hole centers are 29mm apart, so I ended up milling the holes to the correct pattern.
I used a 3/16 mill for the through hole and a 5/16 mill .210 deep for the counterbore. Once this was done, everything assembled without binding.
The second issue was the handwheel: the instructions say to not let the inside surface of the handwheel touch the DRO, but when I tightened the end bolt the handwheel was tight against the DRO.
I solved this by taking .020 off the inside hub of the handwheel.
The DRO has a bit of a grinding feel, and on recommendation from LMS I opened it and blew out the dust bunnies, but there is a strong spring that applies pressure on the encoder, so it seems that it always will have that not-so-silky-smooth feel.
To answer questions about the half-round aluminum extension part, it's there because they provide a special thrust bearing and nut that aren't present in the original assembly--these are hidden inside the half-round aluminum part.
Thank you Frank, very informative and the $89.00 price from Little Machine Shop is the best I can find.
Good to see you back on you tube, I always enjoy your videos. How does it deal with backlash?
Glad your are back, nice video.👍
Thanks. I usually don't do many videos in the summer - busy with family and personal interests. This summer was especially crazy, though. It was our 50th anniversary, we had a family reunion with our 4 kids, 4 spouses and 10 grandkids. Plus my wife had to have two emergency surgeries. She's doing fine, but taking care of her kept me out of the shop for most of the summer.
Pretty slick set up and a very valuable addition to the machine.
Hey there frank! I had an experience of my own to share on the tailstock today. I drilled a 1"1/8 hole in the leblond regal lathe and the damn thing came out! Taper didn't hold it, so I had to throw the part in the freezer and hammer the drill out.
Sounds like a bad way to start the day. Or the week. ;-)
Thanks for the video. What is the purpose of the thick aluminium sleeve that butts onto the tailstock and just seems to extend the length needed for the new treaded shaft? I see at the end of the video it does allow you to swivel the display towards you but I don't imagine that was the reason for it.
I'd bet that the plastic box/electronics/display is somewhat 'generic,' used for many different linear measurement devices and purposes. The adapter blocks lets it fit any similar sized machine. The ram/rod might be more generic too, a few different lengths but not a dozen different diameters.
I just installed mine today. That half-round aluminum part is covering a new thrust bearing and retaining nut that aren't present in the original tailstock.
So why didn't they make it with the display running horizontal?Would make it much easier to read.I think i'll stick with my cheap calipers screwed to the quill.
No doubt one of the many decisions and compromises that go into the design of any product.
Good to see you again Mr. Hoose I have certainly missed your videos. That seems like a nice little DRO for the tail stock. wish that battery was in a better place, but I get why it’s there. If you could release the tabs is there enough clearance to open it with the hand wheel on?
Not really, but taking the handwheel off is pretty easy
That is a useful addition to any small lathe. Being able to zero the reading is essential IMHO. Is there a way to do this?
Yes, just press the red on/off button momentarily to zero the display.
I am going to have to make a DRO for my tailstock. I have a LMS lathe and mill and like them both, but this DRO never worked well for me. After it made me scrap the third part I removed it and went back to stock.
For my work, I like having a separate digital scale for the tailstock DRO.
@@frankhoose I am thinking about a simple mount for a digital caliper. Love the hubcap project by the way! Really cool stuff and machining brass is always a joy.
Would this dro fit a harbor freight 7x10 lathe?
Great video, Frank. Thanks
Nice little mod..
Looks like a nice setup but not sure I do that many critical depth cuts to justify the cost yet. Seems like it could adapt to the cross slide for another version. I seem to fight the high backlash all the time. Not sure I have seen if you have a video how to reduce that on a HF lathe. I like the way you explain things so clear on your video. And just like that aluminum adapter starting out with the flat across the top but then rotating it to suite your taste.
Hi Mr. Frank , Welcome Back .
Neat idea on that locking nut to set screw Frank. This install looks MUCH easier than some of these other DRO items. BTW: Is it me, or did that DRO display look a lot like a bigger version of a Harbor Freight Digital Caliper Display (again, just bigger). LOL
I don't think it has any direct relationship to the HF digital caliper. There are many variations of digital displays on various Chinese tools.
@@frankhoose I just found the resemblance interesting. Guessing from the same manufacturer as those other displays...
Dear sir will this kit be on sale in the uk
I don't know for sure, but I would say "probably", from Sieg's UK dealers
The DRO's I am familiar with are attached directly to a table or a cutting tool so you do not have to worry about backlash error. Does this DRO take backlash into account in any way?
At the risk of being labeled pedantic and yes it is a digital readout, but these are pretty much a rotary electronic counter that displays in theory what the quill travel is. For almost any job I can think of it very likely wouldn't matter, but it can't account for any lead / lag errors in the screws pitch or the backlash like the more normal dro's can that aren't attached directly to the feed screws. I'd still like to add one to my larger lathe if one was available for it. It's a very good idea, but I wish it could be programed for various thread pitches and ordered as a you machine to fit kit of parts so I could adapt one to my lathe. Probably a good amature electronics whiz could whip up what I described with mostly off the shelf parts. Unfortunately I'm not one of those types.
I'm planning on making a video to test the backlash on this device. But for most work, it is small enough that you can ignore it.
Did I miss it? what is the brand of the lathe?
buzzsah I believe he put that on his LMS 5100 he also has a PM, but not sure the model.
@@griplove Thanks, I've been thinking of buying buy the prices being up-there I want to pick it right.
LMS 5100 (7x16). I also have a PM1228 on which I have a linear DRO mounted.
Thank you. Very good, however TMI as usual.
Here's a cheaper version with less to buy & make (just a collar to fit on tailstock front + a bit of drilling & tapping etc.
