I saw what you did there @ 6:13. You need to get the level across the 'flat spots of the ways' but the prismatic sections are 'in the way'. :)

[@Blondihacks]

😬😬😬

[@JaneGraeSmithy]

I worked for several of the highest precision large machine tool companies and gained a reputation as machine leveling “expert”, and you still taught me something. In this case, it was finding that there will be an orientation on your surface (plate) where the level will read level. Great video.

[@TheFeller1554]

The toothpick scale model was a brilliant representation of both ability for machine movement and the effect in real time. Great job!

[@Anony___mous]

I've been a machinist for 12 years and I've never seen a lathe leveled this way. It makes so much sense! and now you've given me something to do tomorrow lol. p.s. I'll keep an eye out for a good deal on a tenths indicator I can donate to the blondihacks cause!

How refreshing, someone who really knows what they're doing and methodically walks you through the whole process - CORRECTLY! Thank you.

[@davesmith9325]

The best tutorial on levelling i have ever seen !

[@johnnycab8986]

It's incorrect. I did it this way and the level was not calibrated (well, it was impossible to calibrate it using this method). If you search for the level axis using a level that is not calibrated and use the bubble in the center, that is not going to be the level axis of the surface plate. You have to find the axis where there is equal discrepancy in both directions, that is the only way to find the level axis with non-calibrated level. After you find the level axis, you adjust the level to get the bubble level, you will have to keep rotating the level and splitting the difference closer and closer and this will probably require very small re-adjustment of the 123 blocks/reference edge. Also, do not fiddle with the screw side as shown in this video, there are small half balls under there which are meant to be the pivot point of the level, you adjust the nuts, not the screw. The incredibly thin slot for the screw is there on purpose to make people avoid fiddling with that side as it will require a specialty slotted head if you want full contact and not risk marring the slot.

[@TCB031]

Best explanation and process to correct that I've seen yet!

[@button-pushing-monkey]

As a machinist with over 20 years experience, though I've never had to perform a machine leveling, this is correct and very well explained. Excellent job sharing info and procedure to keep a dying trade alive!

Reql quick. If one has been a machinist over 20 years, and one has never performed any leveling, how would one know it to be the correct way and very well explained?

Quinn: You're going to need an assortment of precision shim stock. Me: *Goes through recycling bin and assumes Pepsi Max is thicker than Pepsi.*

Soda cans do make pretty good shim stock for that one size. They are made to remarkably precise thickness, to minimize cost of material. 😀

I wonder if cans are a consistent thickness from top to bottom. If they aren't you could use two strips back-to-back in the way wood shims are used in pairs in construction. They would act like the two halves of an adjustable parallel.

I’m just an amateur (recovering woodworker), but this has got to be one of the most informative videos I’ve ever seen. Simple, understandable, and doable by most dummies (and by “dummies” I mean “me”). Now I need to figure out how to mount my mini-lathe on something OTHER than a table made from 2x4s and plywood. (Old habits die hard).

[@PorchPotatoMike]

Rob Johnson Welcome to the Dark Side!

[@smellsofbikes]

If it's a thick table, that's not a bad mounting. Ideally it'd be mounted on concrete, sure, but something that's equivalent to 5" thick wood is pretty resistant to deformation. A sufficiently stiff table can lend a wimpy lathe extra stiffness, though, so error towards overkill.

I work on my "new" 48 Logan ten inch, but I learned on a thirties southbend back in the seventies. It's good to know I'm not alone in the old iron.

[@frankcire1439]

I love your content, it's great seeing machining from a hobbyist's viewpoint without a model maker's overlay. As an amateur machinist, I machine things for my other hobbies and machining is just an adjunct to those hobbies. I don't make models, I make modifications and repairs to other items. I also like how you aren't a machine snob. A new Chinese manufactured machine is often a better bet than an old American machine that has a lot of wear issues, especially if you are going be making small parts.

Where were you a year ago when I did this? You put together all the info that I scraped together from ToT, Tom Lipton, and others. You're doing an amazing service for the hobbyist machining community by putting all this info into a concise series. One of my long term goals is to build a spanning beam lathe stand which would allow me to adjust twist by turning bolts instead of inserting shims under the feet. Should allow much better control and make the whole process easier.

When I got my lathe a year ago, I saw this and made a custom cabinet/stand for my lathe out of steel tubing. The lathe is bolted to the steel frame, and the steel frame is bolted to the concrete floor. There's also adjustable bolts for the frame's feet. To take twist out of the lathe bed, I loosen the hold-down bolts on one end of the cabinet's frame, adjust the feet as needed, then re-tighten the hold-down bolts. Thanks for all the great information and ideas!

Your timing is impeccable. I recently bought that brand's tool that you had to obfuscate in the video, and I'm almost caught up enough on other shop issues to spend a day (I'm slow) calibrating the bed and the tailstock of my lathe. You are a born teacher! To true my mill head, which has neither nod nor tilt adjustments, I had to use shim stock. It was a special form of hell because I had no help in levering the column between shim permutations, but it paid off! So I'm sure it will on the lathe, too.

I had to move to a new shop with my lathe. I reviewed this video I had used 3 years ago to set up my 10X22" Grizzly when it was new. using these techniques I was able to get it cutting at 2/10,000" over 5" in about 2 hours. Thanks for the second time! I have the same Sterrett level, bought it used on eBay after watching this the first time. It took a .020 shim on the tail stock rear corner.

[@colsanjaybajpai5747]

Beautiful demonstration by toothpicks. Great way of explaining.

[@joea9206]

Great methodical video. Anyone who does this will be glad that they took the time every time that they use the machine. I have used an alternative method in the past. After taking the twist out of the ways like you expertly demonstrated, I have chucked on a long bar that was as perfectly cylindrical as i could find or make. If using a CNC, taper moves can be used in a turning operation to make one. I indicate that bar while rotating the chuck by hand until it runs true close to the chuck and also at the far end, thus establishing the true center line of the rotating axis. A four jaw chuck or buck chuck helps with this. Getting it true at the front first. then tapping the far end, usually having to go back and forth to get it good on both ends. It's critical that the bar is solidly mounted in the chuck so that rotation doesn't affect it. Once I got good run-out on both ends, an indicator mounted on the tool post with the tip on the bar allowed me to tweak it in by traversing back and forth with the spindle off. For the tail stock adjustment, a 60 degree center for the chuck end can be made on the machine if one is not available, this also assures that it runs true if not disturbed after the turning of it. Keep up the great videos.

[@tomsmith3045]

Most clear and concise demo of this that I've ever seen. Thanks!

[@DARANGULAFILM]

Thank you for this presentation. I have a 20 yr old Taiwanese small "desk" lathe which was apparently made for US high school trade classes. I also do little more than dabble, mostly turning down bolts or making custom lens mounts. It has a very short bed and beyond the four corner bases under the machine itself, there are no other apparent alignment adjustments. I found it adequate for making my custom lens mounts with alloy and flowcast bronze with sharp tools. Machining steel became difficult but doable. However I just about dropped down on the floor in a dustraising tantrum the first time I tried machining along any length. It also flexed too much for ceramic cutters to be used which either rode or dug in. I have fixed it down to a very heavy solid piece of construction steel "C" section. It no longer chatters so easily and the longer cuts have improved even before any shimming which needs still to be done. Your presentation is very helpful for making what finer adjustments yet need to be done. I also made a recirculating feed for cutting oil by adding a drain tube to the chip tray, using a GM powersteer pump in a small oil tank and a washing machine motor to drive it.

Hi Blondihacks, Sheldon from down under here. I have been a home machinist for a number of years now. Your video of how to reset the bed is awesome. I have had problems with my lathe turning tapers etc, as the lathe was dropped when I was shifting. I have tried your technique and the lathe is now within 2 10ths (6 inch) out of the chuck. Before, it was running about 3 tho of run out. You are one of the best machinists I have come across to explain all this machining in detail. By the way I have 2 ragdolls that help me on the lathe too! Damn fur!

Brilliant video I have seen a lot of machine shop videos on you tube yours are the best. Most of us out here in the real world have Chinese or maybe Taiwan made equipment and need to know how to optimize what we have. A lot of machine shop snobs tell us to buy the mostly mythical pristine USA made lathe or mill for an affordable price which rarely if ever exist in reality. By far most of the affordable domestic machinery is huge clapped out industrial size machinery that would require even more work and expense to bring up to standard and would require expensive shipping and riggers to set in place and 3 phase electricity which almost nobody has at home. Sorry to rant but well done lathe leveling and set up video.

[@Blondihacks]

Aww thank you! ☺️

[@drd1924]

Great Vid with all the correct tricks in the correct order for aligning a lathe. For those who have adjustable feet/bolts at each corner, once you get close it will only take like 1/16 of a turn or less at one corner to make a noticeable difference. Make sure you lock the locknut down at each adjustment because if you forget and everything is square to the world, THEN have to lock the locknut, it will change simply due to bolt stretch.

[@frankhaydon658]

I am lacking machinist level with an old Taiwan lathe that has never worked well(always cutting different at the extremes) I chucked up a pencil laser in the head stock an ran at maximum rpm and put a piece of white paper on the end of my tail stock and tweaked the bed until the laser image was centered on the tail stock. The image stayed centered when i moved the tail stock next to the chuck. The test cuts were right on. You can shim the lathe with the machine running.

[@siggyincr7447]

Great instructional video on an often overlooked subject, even by a lot of experienced machinists. The only thing I could think to add is that used lathes can have significant wear on the ways themselves that is usually concentrated on the part closest to the spindle (90% of lathe use is within inches of the chuck). The uneven wear pattern on the ways can mess with the alignment process.

[@oldfarthacks]

The best way to fix that is to install a CNC control, then you can program in your error table for correction factors.

One of my V belts finally wore out To change it I have to remove the spindle So while I have the spindle out I may as well adjust the bearings. Now with the bearings a bit happier I have made some adjustable feet and have the machine nice and level. I have a nice hunk of about 1.5 inch bar sticking out of my chuck. My spindle is tiny at about 3/4” hole going through but that is how they made them back in ww2 days. I’ll use a steady to put my centre in the end. Thanks for inspiring me to get into this. That and thanks to my old v belt . Love the Chanel, keep it up. Dave

Yep Davo, I know your problem. Mine started with I bought a Chinese mini lathe.

[@DavoShed]

@@oldfarthacks I know those mini lathes can be pretty average machines. Now that you have it take it as a challenge to make it work at its best and make some really nice parts anyway. I have spent as much on accessories as I did on the lathe originally 🤠. I bought a face plate and a milling attachment. My cross slide has worn in the middle of the stroke and is a bit sloppy now. I’ll make a video on re machining that when the time comes. My lathe features in a couple of my videos if you want to check it out.

VERY nice video. I learned how to align my lathe today, and learned how much i didn't know. Thank you so much.

I am watching this on Christmas morning! Yes I'm sad! Thank you for posting this Quinn as in the next few days I will be installing my lathe/mill into my newly enlarged rebuilt 8' x 7' shed small I know but it was 8x5 before! And this will help me enormously. Fortunately I have a10" Rabone precision engineers level which I will calibrate as per your demonstration so thank you so much for the input! Wishing you all the best for "The Holidays"as you Americans put it or us Happy Christmas lol to you and your family. Subscribing now!

[@christopherjones7459]

Excellent explanation. I have followed you advice and now have excellent results. Thanks

Hi Quinn, Bought a can of the Boeshield T-9 mentioned in another video. Is working great on my Swag Portaband V1. Happy Holidays to you and the family.

[@owenclark7210]

Good info. I'll be re-building my mini lathe over Christmas, so I'm sure I'm going to need to do this. Merry Christmas Quinn and give Sprocket extra treats.

Well done Quinn. Always enjoy your videos! I have an Enco 12x36 geared head lathe model 110-2075 and I am having a heck of a time getting the headstock aligned to the ways. The lathe is perfectly level or no twist in the ways, I can turn a test bar and get .003” taper in 6” smaller at the chuck end. I loosened up all the bolts that hold the headstock to the main casting and loosened the adjustment screws just to get all of the stress out of it. The closest I can get it is about .0015” over 6”, and when I do get it that close it only takes one heavy cut to throw it back out again. I aligned the tailstock with a coaxial indicator in the 4 jaw and swept the ID of the tailstock spindle and it’s within .0005”. Driving me nuts why I can’t get a good straight cut on this machine. It hardly has any wear

[@Blondihacks]

If a heavy cut is causing the headstock to shift, something is very wrong. How heavy of a cut are we talking about? Maybe the machine isn’t rigid enough to do what you’re asking. I would also check the chuck, centers, tailstock height, and spindle bearings. If you can’t get it aligned within a couple of tenths, keep working on why. You won’t get good cuts until the machine is aligned well and stays that way.

these are some of the best machining videos Ive seen

[@Blondihacks]

Wow, thank you! ☺️☺️

She is good enough to be in a very select and outstanding group. Yes, Joe does pick on her from time to time, but he also shows her respect, as he should given that she does not have his shop.

[@dalejones4186]

Awesome job explaining. Now I know how to do it. Thanks Quinn.

[@stephensarkany3577]

Just enjoyed watching the process, will tune in later.

[@28gwdavies]

Thank's for that, I'll be doing a major overhaul on my mini lathe shortly so I've put this video on my desktop for reference later. Have a nice Christmas and all the best for the New Year from me here in England.

[@todds4101]

Love the toothpick example! Never thought about it that way! Nice job as always.
