I too am the proud owner of a scrap bin lathe, trucking company leaving a location, opted to throw a 12x36 Atlas lathe away. I have profound dumpster diving tendencies, so I ferreted through the dumpster and retrieved all I could find. It was not a plug and play, I rebuilt, replaced and repaired as needed, It's been a great treasure and does good work.

I have 6 atlas lathes I've bought and restored holding on while prices climb,, 2 -12 x 36 with quick change gear boxes and 4 6 inch 618s and pretty much every attachment for them,, can do great work with the 12 inch but doing light cuts,, and does better with high speed steel tooling,, but just bought my dream lathe 11 inch Logan same 54 in length bed as atlas but has 300 lbs more weight and oil filled apron with clutch and vways,,, you being a machinist I'm sure are aware of the atlas limitations,, but they really bring great money now and parts can be found, engineers really dropped the ball with the.oo42 finest feed rate but I overcame it by switching drive gear on banjo to half the teeth really cuts fine now,, and I only lose first row on thread cutting chart ,, and can switch gear back if needed,, but the Atlas was more the hobbyist lathe and didn't see school shops or factories,, really are nice machines..was looking for a Atlas horizontal mill but found a Sheldon horizontal mill no0,, really nice mill,, good luck with yours

I would recommend disassembling your new chuck and cleaning it out. You will likely find a lot of grinding dust in it as well as some very thin oil. It looks very similar to my PM1236.
Thanks for bringing back memories from high school metal shop class. I am still proud of the projects I made; a center punch, a machinists' hammer with a turned and knurled handle and a case hardened head, and of course the bent aluminum letter holder for mom. Back then (~ 1960) we did not have digital readouts, so I used a micrometer to determine how close I was to the final spec. Today, I'm pleased that I can follow what you were doing and understand the problems you solved along the way. And thank you Mr. Holt, wherever you are.

Didn't expect my highschool shop teacher to pop up in my recommended 😅 your shop class landed me in light duty automotive for the last 6 years. I use the basics you taught me every day. I remember me and a class mate in a little older VW Jetta, you were livid we left in the middle of class to get car parts without asking 😂 Thanks for getting me into trades! Edit: That reminds me, you never saw it, but I left chuck key in the lathe (about 5 minutes after you'd told me to make sure not to) and turned it on, lucky for me I had my facemask on, thing smacked me so hard it rung my ears 😂😂
I went and circled the "Never Leave The Chuck Key In The Chuck" sign in memory of you, thanks. Good times. I have fabricated five new chuck keys for the lathes so far.
$1400 for a lathe in that condition, now working, is a VERY GOOD DEAL! Prices of used machines that size (super desirable!) are through the roof if they are in any reasonable condition! And with a working digital readout? ROBBERY!
I figured as much 2 year's ago and started buying them up here in Delaware and restoring them,, l have 6 atlas lathes now 2-12x36 with quick change gear boxes and 4- 6 inch 618s and a 11 inch Logan and Sheldon horizontal mill and pretty much all attachments and tons of tooling,, have only invested 3000 dollars in everything,, I've seen the prices rise to over 4 times what I payed as people realize vintage machines are still better than buying new unless you really pay up,, l will never sell my Logan lathe and Sheldon horizontal mill,, but will be selling all the atlas's soon,, l figure the 2 12 inch with quick change gear boxes will recoupe all the money l put out and others will be profit as well as the attachments that bring crazy money, the 4 milling attachments are bringing 400 dollars a peace now,, l have one 618 that's never been used like brand new,, beautiful machine. Atlas lathes was more the hobbyist lathe and was taken good care of by most that bought them..
Good gawd... it must be the ultimate power of the Teacher.... all that video and at the end not a single cut run or test of DRO accuracy.... NOTHING ! " See ya Monday, kids ! Class dismissed ! "
Just last month I was at an auction and we were touring the shop that was going out of business. The usual standard machine shop suspects except for this old Clausing Colchester lathe that had all kinds of crap stacked on top like it had been used for storage a long time. There was a red tag on it that read No Longer In Service. I immediately told my banker we’re buying that thing. Keep it quiet. I ended up getting it for less than scrap value and all that was wrong with it was a damaged gear. Added a DRO and glass scale and I ended up with a killer lathe.
It's the paradox of all hobbyist(?) machine tools, you spend most of your time after acquiring them using them to do repairs and upgrades of that same machine tool.
There's a slight chance the DRO design needs a negative voltage somewhere but most likely it converts AC to DC right at the input. A 12V DC power supply might also work.
I have a similar lathe and had to make some of the retainers like yours. Literally yesterday of this comment date. To form the flats I just clamped it in the lathe chuck and filed them down. For sure, no need to heat treat but won't hurt anything to do it.
The roll-pin has an install direction. Put the split towards or away from the force on it, if the split is at 90 deg., then it is constantly getting closed up and squeezing may/can loose its tension. Peugeot trans shifter forks class 1972. Thanks, nice vid.
He is a great shop teacher i used to have a blast getting under his skin lol Jokes aside this guy is truly brilliant he was knowledgeable and a great teacher that ten years ago fore me. One of a dying breed of teachers much respect it looks like he is still at it.
Reminds me of a Niles lathe I rebuilt. It was 10 feet tall 30 tons with a 6 foot chuck, 40 foot ways in 2 sections 20 tons each. The carriage with tool post was 4 feet high, weighed 5 tons, and the tail stock 4 feet high weighed 3 tons. Electric motor for rapid travel, and a "trailer hitch" to move the tail stock. But the bosses didn't want to over tax the motor so we lifted the tail stock with the overhead crane to slide it along. Hand precision scraped the ways, and took 2 weeks to precision straighten, and level. To set to the .001' spec. with precision levels even though the ways were 4 feet wide, and 2 feet high made of 8 to 10 inch thick steel it handled like trying to straighten a wet spaghetti noodle. Best thing I made on it was a satellite frame for NASA.
You bought a lathe with broken parts, some of which need to be turned. "On what shall I turn it, dear Liza, dear Liza? On what shall I turn it, dear Liza, on what?" "On the lathe, dear Henry, dear Henry, dear Henry..." Good thing it wasn't the only lathe you had...
7:24.... and there it is. hands down, the absolute WORST FEATURE of these lathes. if i had seen it, even thought about it when i bought mine (new) i would have saved up a bit more and coughed up for the "big sister". the tailstock is FLUSH at the front. that lack of overhang is a CURSE. which is what i do everytime i have to work between centers. and yet, in the parts manual, its shown as it "should" be. someone, somewhere in a factory many years ago, set up a jig wrong, and thats how theyve stayed, i reckon. (i believe the grizzly 12x36 has it right, but im not about to pay shipping fees across the pacific?) i have plans for hacking it up and making it into a lever/ram type thing with dovetails... just enough meat in the casting to do so. come in handy for shaping/slotting as well then.
UA-cam is smarter than I thought. It popped up this video for me today and I am already subscribed and loving it. I am not only attracted to fixing older machinery but by the fact you are a machine shop teacher. Here in the USA we have nearly done away with any sort of hands-on training. Sad, 60+ years ago (yes, I am that old) I was on my way out of high school at 16 because I was a typical teenage rebel and couldn't stand sitting in a classroom. A wise guidance counselor (Thank You, Miss Tate) convinced me to finish the school year by taking just two courses: Mechanical Drawing and Machine Shop. This made all the difference in the world ... not only kept me employed and eating all my life but likely kept me out of prison. Thank God for machines and those dedicated to teaching them.
Those chucks can be reasonably good butvthey come from the factory full of grinding dust. There are several vids here on yt of guys dismantling them and removing shovels full of crud. Cleaning to prolong life is highly recommended
Somebody referred to the adage which advises “measure twice, and cut once”, and somebody else said, (perhaps as a joke), “Measure once, cut twice - I like that”. This reminded me of an old joke, about the carpenter who had difficulty fitting a piece of wood to his construction. As he contemplated his difficulty he said, “I just can’t understand it, I’ve cut it twice and it’s still too short”.
"the guy who mounted this was drunk" & "always research after" thats the comments who gets a Swede to become a subscriber, just found your channel, enjoyed every minute. Good job.
He MUST be from Canada! Any shop teacher here in the USA (back when they were still in stock) certainly wouldn’t have said “buggered” or “heck”. He’s either Canadian, a Mormon, or both. Either way, I loved it! Just wish that I could have had him as my shop teacher when I was in school. Loved the restoration and your practical knowledge. Now if I can just find a broken lathe for steel scrap prices…
very glad to see you were able to pick up someone else's mistake for scrap. Sometime the scrap results from an error in judgement, or technicians who do no like work. or some body really wanted a bigger shiner toy and dispose of what was on hand. good luck
Enjoyed your video, you have a way that keeps my interest peaked . There was not a teacher I knew when I went to school that could ever do that. I would have enjoyed being a student in your class room !
That is what I did in Berlin 1945 we overhaul machines from burnt out factories. And that's how I got my aprendentship after 3 years of hard work and became a machinist.
Seriously... I'm only 32, and I wasn't aware of this travesty. They're just trying to strip kids of any practical skills. I was appalled at my niece's lack of mathematical knowledge... then she tried to explain the common core crap and I couldn't wrap my head around it either. I told her no wonder you can't do; it doesn't even make sense. I had her doing double digit division and multiplication within an hour... so it clearly had nothing to do with her ability. We need real PE not limp wristed crap, no sweat no grade, we should learn to sew, grow, forage, navigate, welding, woodworking, automotive. History class is taught wrong. Heck most classes are taught wrong. People think they don't need math beyond arithmetic, but differential equations can be useful for all kinds of things (practical stuff like buying a car, choosing how best to invest your money, or improve efficiency).
Funny. If you had a lathe, you could make whatever parts you'd need to fix this lathe lol. Awesome find, those are workhorses! Edit: commented before seeing you manufacture your own parts lol. See, having multiple lathes is necessary... I wish my wife believed me 😂
In most cases when something requires AC power it's just being rectified to produce DC anyway so you can connect DC to it and it will work just the same. I suspect that 9 VDC would work OK.
I worked in a shop that had a lot of larger equipment. We had a technician come in to repair a power feed on a (Italian made) 36" swing drill press. There was a bad gear in the feed. He wanted $4k to have the gear made and to reassemble the press. I was able to find the gear online for $150. Put it back together and it worked fine. Machine tools are usually pretty simple. I rebuilt most of a Logan lathe built, and used, since 1945 by a guy that built his own aircraft. It works great for my hobby projects. I love that lathe because I fixed it up...and it works! Very satisfying!
I like the way in which this project was undertaken. Too many tools, appliances, or machines have been discarded by people who did not want to repair them, or perhaps did not know how to repair them. The work you have done here shows that good results are possible, and I thank you for providing this video presentation. I do however have a question, and I hope to get an answer, which relates to a word you used at 16:06 and 16:10. It sounds like the word “SODDER”, but you were connecting wires to electrical terminals with SOLDER. I have only ever known this word to be pronounced the way it is spelled, so that it sounds like “SOLL-DER”. Can you please explain the reason for the pronunciation which was used in the video?
I pronounce "Solder" with a silent L. I don't know if it's a Canadian pronunciation, or a dialect from my area of my Province, or I just have never heard anyone pronounce the "L" here.
One of the great things about (older) machine tools is yeah, they're held together with fasteners, so you can take things apart, fix them, and then put them back together. Also nice when you get a 'one tool many badges' machine. Makes finding parts a lot easier.
I don’t even use my three jaw track. I have one and it sits on the floor of the shop collecting oil and dust. I stick with my four jaw chuck. It only takes me a minute or two to center any work piece I might have.
I went to a rare earth magnet seller on line and purchased a bunch of 1/16 square 1" long magnets, and they are great at entering small holes to pull out springs and ball bearings.
How much did you pay for it? How much does one like that go for working? I found 2 massive drill presses and 2 massive bandsaws for less than $100 each and they worked but need cleaning. I figured the motor alone on each one was worth that much in scrap material
@@GregWellwood they must be paying pretty good for scrap in canada right now.... that's more than triple for what you could expect to pay for a scrap chinese lathe
This was great watching an old hand lathe being brought back to use again. This is a good excuse to by a bigger truck for future projects. Thanks for sharing this.
Good job getting that thing working. A suggestion for your new chuck. I would take it apart and clean it well. Most Chinesium products have a lot of grit inside which can cause premature wear. Thanks for sharing. Cheers
I laughed when you said "Gestetner". I have not heard that word since the 70's. Remember that fantastic smell the copies had? Used to just love that as a kid.
I got a Monarch 12CK for $400 from a scrapyard. It was missing a small cover plate on the headstock, had a couple of broken levers, and was missing the tailstock. One lever got fixed, the tailstock and other lever were bought off eBay, and I made a cover plate. The huge old motor is 220 volt, three phase, three horsepower. 220V VFDs top out at 3HP so I got one and mounted it. After getting the clutch fixed and adjusted, the VFD only has a problem if the headstock gearing is in the highest speed range. I just have to slip the clutch a little. Any other range I can just move the lever. It's a wondeful old WW2 (circa 1943) machine.
measure twice cut once... I wouldn't have destroyed that sleeve just to gain an inch of travel on the tailstock but, it's yours, not mine. when u get a hard time removing the chuck from the barrel or another sleeve, you'll see why they made it like that
@@GregWellwood no worries. I'm holding you to a high standard if you are an educator. We don't like the new guys doing silly stuff that damages tooling and machines. I would tell my kids or learners to absolute position or "origin" from the one inch vernier marking.
@@MrRoger27 just as an FYI, its not a drive tang, Morse drive from the taper. The tang is just there for knocking it out. and as was shown on a lot of tail stocks you can just go to the end and it pops out.
As I understand it, he came from auto mechanic background where they often work in un/under heated garages and those coveralls are a plus. Not to worry. The kids get "free" government medical care when things go wrong.
I never took shop in high school because a) no girls took shop and b) the shop teacher was real bastard. I regret not exploring machining as a kid as it my favorite hobby/obsession now 40 years later. Maybe if you or someone like you had taught shop at my school the world would now have one less lawyer and one more machinist today. Great channel, keep it up.
Who uses 7Vac for anything? That is crazy!!! Plus, 450 MV is not enough… “I’m giving it all she’s got Captain! I hope the Dilithium Crystal’s hold out, the deflector shields are pulling all of our power of the propulsion system, Captain!” Scotty out!
We don't get to see it work? How do we know anything you did was successful? That's two, too many questions. Try again. No sub. I slightly dislike this.
Yea been thinking about all the skill center schools and trade schools being knocked down and real-estate ..land being sold for apt units I'll keep an eye in dumpsters and buddy up with crews
great content! found you through the canadian metalworkers forum...takes me back to high school shop class, just listening to the way you share the information...top notch sir...top notch
I have this same lathe, in the Precision Mathews variant. At least it looks the same! PM 1236 is Lathe Model. Gives me encouragement that you can put an 8-inch chuck on the lathe.
I got my Koping so cheap I could’ve made money taking it to the scrap yard it’s 8000lbs of greatness 16”x10’ between centers metric dails inch and metric threading with inch lead screw which I guess makes since since metric threading is odd no matter what lead screw you have but all in purchase price new 7.5hp motor well new to me Baldor loading fee a new vfd and some wire I’m under scrap value still honestly if I were to ever rescrape the compound it’d be a perfectly fine machine as is it has some quirks tho
THANK YOU THANK YOU for doing this video! I have the Old Harbor Freight version (Gearhead 12x36) of that one, now Grizzel sells it. Have not had the roll pin issue, but this shows me how/where I will mount a DRO someday, that 8 mm (8mm), sized oilers, and more of the workings of my lathe in general. I need a better oil can though and help on that, I use a Goldenrod with a screw on tip a little recess in which I beveled an area for an 8 mm 'O' ring. I have in the past pushed in those balls and had them not come out. I do have a switch issue with mind randomly using the lathe it just turns off. Waiting for Grizzley to send me a new one (BACK ORDER!), my 3 jaw chuck was not worth much could not use a parting tool bought the 4 jaw 8" love it of course you have to indicate everything. I have Accusize 252-222 BxA I do to this day still do not understand the sizes! AxA BxA could you do a class on that please?
In the future, if a cable is moving you should use a multi-thread cable, not a solid core one. If you want to use network cable, then use ‘jumper cable’ which is multi-thread, more flexible, and thus will not break. A broken cable can induce a meta-stable/erratic condition that is very difficult to diagnose
Check the chuck to see if the one of the scroll pinions is marked. It with be the only one that will have accurate accuracy when the jaws are tightened. It’s called the nominated pinion, and was the one used when the jaws were ground. Good job on the lathe.
Machine has only cosmetic issues - the ways are in good shape. This is why one should not expect a huge discount. Strange choice for DRO. Accusize is more expensive than most resellers of Chinese stuff - they pretend they have a "brand" - they do not. Main advantage with them is quick response time to questions.
You can always make an AC supply that is a bit high in voltage into a bit lower voltage by putting pairs of diodes connected in inverse parallel (each diode's cathode to the other diode's anode). The cost of diodes is minimal. Each pair of diodes drops about 0.7 volt without much affecting regulation.
What you are doing is exactly the job that my dad did for Battleground School District in Battleground, Washington. My dad has been gone 25 years but watching you do what my dad did was very interesting to me. It takes a whole bunch of knowledge and common sense to do this.
No need to mill off the bottom of the endthread. Open up the back end of the drillaperture and put in the thread from there. Nice piece of scrap though, shure got yourself some value there!
The flange stops the tailstock quill falling out if you wind it all the way out. I think you will find it was possible to shorten the tailstock thread by a small amount instead of taking the end off your chuck. When you have a Digital readout you loose some "length" of the tailstock. If possible adding clamp bolts between the saddle and the compound slide assembly. Rigidity is your friend.
Wait. Lol. Hold on a sec. So you're telling me you're a shop teacher, that teaches safety, whilst running a lathe with long sleeves? 🤔 Cool video though. Roll your damn sleeves up though before you become human hamburger meat, dude.
Good for you! I have a newer version of this lathe new from Grizzly. My head stock was full of metal chips from the factory. many people ended up changing all the bearings because of this. I would advise opening the top lid and at least taking a look and check the run-out at the chuck end of the spindle. I still love the lathe after all. Rich
I did not check the ways. "If you can't afford to fix it, don't measure it." They don't _look_ knackered, but we'll see if it's the machine that's the limitation, or my absence of skills....
@@GregWellwood At some point you have to decide what's good enough and just start using the machine. Not every lathe needs the Keith Rucker/Rotary SMP treatment. Much as I like watching a 72 part series on hand-scraping a lathe bed, I'm sure you have more interesting projects to pursue :)
I have the exact same lathe. I had the same roll pin fall out twice. The hole was slightly larger and would not hold the pin securely. I solved it with some airplane lock wire. It's a pain taking the carriage off. I dread the day I have to source any parts for it.

Come on, man. How lucky are you to find a lathe at the price of a pile of scrap metal? I would like that too. Uff👍👍👍
How you exactly came across a lathe at scrap price would have been the best information of the whole video!
The right place at the right time. You can't exactly craft that. I wasn't looking for a lathe, as I already had a 10x27. I just couldn't say "no."

Great build- but I would have taken the opportunity while it was stripped to paint it.
No need…
I wanted to see this thing work! Consider ending all of your rebuilds with a demonstration of the thing you fixed, okay! ...just cause. :~)

hands down, the absolute WORST FEATURE of these lathes.
if i had seen it, even thought about it when i bought mine (new) i would have saved up a bit more and coughed up for the "big sister".
the tailstock is FLUSH at the front. that lack of overhang is a CURSE. which is what i do everytime i have to work between centers.
and yet, in the parts manual, its shown as it "should" be.
someone, somewhere in a factory many years ago, set up a jig wrong, and thats how theyve stayed, i reckon. (i believe the grizzly 12x36 has it right, but im not about to pay shipping fees across the pacific?)
i have plans for hacking it up and making it into a lever/ram type thing with dovetails... just enough meat in the casting to do so. come in handy for shaping/slotting as well then.
UA-cam is smarter than I thought. It popped up this video for me today and I am already subscribed and loving it. I am not only attracted to fixing older machinery but by the fact you are a machine shop teacher. Here in the USA we have nearly done away with any sort of hands-on training. Sad, 60+ years ago (yes, I am that old) I was on my way out of high school at 16 because I was a typical teenage rebel and couldn't stand sitting in a classroom. A wise guidance counselor (Thank You, Miss Tate) convinced me to finish the school year by taking just two courses: Mechanical Drawing and Machine Shop. This made all the difference in the world ... not only kept me employed and eating all my life but likely kept me out of prison. Thank God for machines and those dedicated to teaching them.
Those chucks can be reasonably good butvthey come from the factory full of grinding dust. There are several vids here on yt of guys dismantling them and removing shovels full of crud. Cleaning to prolong life is highly recommended
Somebody referred to the adage which advises “measure twice, and cut once”, and somebody else said, (perhaps as a joke), “Measure once, cut twice - I like that”.
This reminded me of an old joke, about the carpenter who had difficulty fitting a piece of wood to his construction. As he contemplated his difficulty he said, “I just can’t understand it, I’ve cut it twice and it’s still too short”.
Brilliant video , you really are entertaining to watch , nice restoration , its nice to see another machine saved from the crusher .
"the guy who mounted this was drunk" & "always research after" thats the comments who gets a Swede to become a subscriber, just found your channel, enjoyed every minute. Good job.
He MUST be from Canada! Any shop teacher here in the USA (back when they were still in stock) certainly wouldn’t have said “buggered” or “heck”. He’s either Canadian, a Mormon, or both. Either way, I loved it! Just wish that I could have had him as my shop teacher when I was in school. Loved the restoration and your practical knowledge. Now if I can just find a broken lathe for steel scrap prices…
very glad to see you were able to pick up someone else's mistake for scrap. Sometime the scrap results from an error in judgement, or technicians who do no like work. or some body really wanted a bigger shiner toy and dispose of what was on hand. good luck
I'm quite jealous, you just can't find something like this in australia. Some people want a ferrari, I'd like a lathe.
I've had a very similar piece of crap machine for the last 27 years,
Enjoyed your video, you have a way that keeps my interest peaked . There was not a teacher I knew when I went to school that could ever do that. I would have enjoyed being a student in your class room !
That is what I did in Berlin 1945 we overhaul machines from burnt out factories. And that's how I got my aprendentship after 3 years of hard work and became a machinist.
You might want to take the chuck apart and clean it. My Chinese chucks have all been full of grinding dust and grit.
and throw a rubber gasket in there somewhere... i recall a gap that lets swarf sneak into the scroll and bevels...
"Shop" is taught in Canada? It is no longer taught in the USA. Go Figure!
Seriously... I'm only 32, and I wasn't aware of this travesty. They're just trying to strip kids of any practical skills. I was appalled at my niece's lack of mathematical knowledge... then she tried to explain the common core crap and I couldn't wrap my head around it either. I told her no wonder you can't do; it doesn't even make sense. I had her doing double digit division and multiplication within an hour... so it clearly had nothing to do with her ability. We need real PE not limp wristed crap, no sweat no grade, we should learn to sew, grow, forage, navigate, welding, woodworking, automotive. History class is taught wrong. Heck most classes are taught wrong. People think they don't need math beyond arithmetic, but differential equations can be useful for all kinds of things (practical stuff like buying a car, choosing how best to invest your money, or improve efficiency).
Funny. If you had a lathe, you could make whatever parts you'd need to fix this lathe lol. Awesome find, those are workhorses!
Edit: commented before seeing you manufacture your own parts lol. See, having multiple lathes is necessary... I wish my wife believed me 😂
In most cases when something requires AC power it's just being rectified to produce DC anyway so you can connect DC to it and it will work just the same. I suspect that 9 VDC would work OK.
"and I'm already looking forward to being disappointed"- that's a phrase that I can really relate to in life!
I worked in a shop that had a lot of larger equipment. We had a technician come in to repair a power feed on a (Italian made) 36" swing drill press. There was a bad gear in the feed. He wanted $4k to have the gear made and to reassemble the press. I was able to find the gear online for $150. Put it back together and it worked fine. Machine tools are usually pretty simple. I rebuilt most of a Logan lathe built, and used, since 1945 by a guy that built his own aircraft. It works great for my hobby projects. I love that lathe because I fixed it up...and it works! Very satisfying!
I like the way in which this project was undertaken. Too many tools, appliances, or machines have been discarded by people who did not want to repair them, or perhaps did not know how to repair them. The work you have done here shows that good results are possible, and I thank you for providing this video presentation. I do however have a question, and I hope to get an answer, which relates to a word you used at 16:06 and 16:10. It sounds like the word “SODDER”, but you were connecting wires to electrical terminals with SOLDER. I have only ever known this word to be pronounced the way it is spelled, so that it sounds like “SOLL-DER”. Can you please explain the reason for the pronunciation which was used in the video?
I pronounce "Solder" with a silent L. I don't know if it's a Canadian pronunciation, or a dialect from my area of my Province, or I just have never heard anyone pronounce the "L" here.
@@GregWellwood American English (and Canadian) has a silent "L" in solder. British English doesn't.
Just rotate the tailstock brass nut 120deg and you have your extension stop again.
One of the great things about (older) machine tools is yeah, they're held together with fasteners, so you can take things apart, fix them, and then put them back together. Also nice when you get a 'one tool many badges' machine. Makes finding parts a lot easier.
I don’t even use my three jaw track. I have one and it sits on the floor of the shop collecting oil and dust. I stick with my four jaw chuck. It only takes me a minute or two to center any work piece I might have.
Brilliant attitute, love your style Sir. Keep up the good work.
That was a pseudo-epic journey, maybe the next one will have a wine dark sea in it too?
I went to a rare earth magnet seller on line and purchased a bunch of 1/16 square 1" long magnets, and they are great at entering small holes to pull out springs and ball bearings.
How much did you pay for it? How much does one like that go for working? I found 2 massive drill presses and 2 massive bandsaws for less than $100 each and they worked but need cleaning. I figured the motor alone on each one was worth that much in scrap material
At this point, the purchase itself and all the parts have me at $1440 all in. (CDN$)
@@GregWellwood they must be paying pretty good for scrap in canada right now.... that's more than triple for what you could expect to pay for a scrap chinese lathe
This was great watching an old hand lathe being brought back to use again. This is a good excuse to by a bigger truck for future projects. Thanks for sharing this.
Good job getting that thing working. A suggestion for your new chuck. I would take it apart and clean it well. Most Chinesium
products have a lot of grit inside which can cause premature wear. Thanks for sharing. Cheers
Will do!
I laughed when you said "Gestetner". I have not heard that word since the 70's. Remember that fantastic smell the copies had? Used to just love that as a kid.
I had a Mrs Chalk handing out Gestetners...
The hardest thing to get in a shop is the passion to do the work. You have plenty of that. God bless you and your family amen and aloha
I got a Monarch 12CK for $400 from a scrapyard. It was missing a small cover plate on the headstock, had a couple of broken levers, and was missing the tailstock. One lever got fixed, the tailstock and other lever were bought off eBay, and I made a cover plate. The huge old motor is 220 volt, three phase, three horsepower. 220V VFDs top out at 3HP so I got one and mounted it. After getting the clutch fixed and adjusted, the VFD only has a problem if the headstock gearing is in the highest speed range. I just have to slip the clutch a little. Any other range I can just move the lever. It's a wondeful old WW2 (circa 1943) machine.
Good thing there was a Princess auto on the route.....Kinda like the US harbor freight. (sorry not quite the same....My wife is Canadian)
🎉Great Job！ I need your service and partnership for the Preowned Machine business.
measure twice cut once... I wouldn't have destroyed that sleeve just to gain an inch of travel on the tailstock but, it's yours, not mine. when u get a hard time removing the chuck from the barrel or another sleeve, you'll see why they made it like that
Yeah, not sure we should be teaching the kids to cut the drive tang off!!
This has already come up in the comments. A new sleeve is back-ordered - mine does NOT have anything to hold the tang.
@@GregWellwood no worries. I'm holding you to a high standard if you are an educator. We don't like the new guys doing silly stuff that damages tooling and machines. I would tell my kids or learners to absolute position or "origin" from the one inch vernier marking.
@@MrRoger27 just as an FYI, its not a drive tang, Morse drive from the taper. The tang is just there for knocking it out. and as was shown on a lot of tail stocks you can just go to the end and it pops out.
Not sure how you found your way into my suggested list but glad you did and subbed for good measure!
Few things say Canada like Princess Auto.
Not impressed with the loose sleeves he is wearing. This is inviting a serious injury... and this guy is teaching kids!
As I understand it, he came from auto mechanic background where they often work in un/under heated garages and those coveralls are a plus. Not to worry. The kids get "free" government medical care when things go wrong.
I never took shop in high school because a) no girls took shop and b) the shop teacher was real bastard. I regret not exploring machining as a kid as it my favorite hobby/obsession now 40 years later. Maybe if you or someone like you had taught shop at my school the world would now have one less lawyer and one more machinist today. Great channel, keep it up.
Bro... do you need some proper lifting straps? Lifting with ratchet straps is a gamble.
Bro... Open for sponsorship.
Harbor Freight has lifting straps that work great and are quite cheap, too.
Great job on that DRO, only a shop teacher machinist would measure with a machinist rule between zip ties on that DRO cable, LOL, good job all around.
Who uses 7Vac for anything? That is crazy!!! Plus, 450 MV is not enough…
“I’m giving it all she’s got Captain! I hope the Dilithium Crystal’s hold out, the deflector shields are pulling all of our power of the propulsion system, Captain!” Scotty out!
you can tell hes a true canadian because hes using a robertson drive screw
Brilliant hope you have years fun.
Fantastic video loved it.
That's an excellent lathe. I have one (different name, same Taiwanese made unit) that I bought brand new.
We don't get to see it work? How do we know anything you did was successful? That's two, too many questions. Try again. No sub. I slightly dislike this.
I don't slightly dislike dislike this.👎
Yea been thinking about all the skill center schools and trade schools being knocked down and real-estate ..land being sold for apt units I'll keep an eye in dumpsters and buddy up with crews
I know little about machining but it looks like a good way to occupy a lot of time.
Approximately how much did the entire scrap to working lathe cost you? How much was the SCRAP VALUE of that much steel?
great content! found you through the canadian metalworkers forum...takes me back to high school shop class, just listening to the way you share the information...top notch sir...top notch
There's a Canadian Metalworkers Forum? I'm off to check it out!
Someone’s been inspired by AvE 👀🧐😎😂
Thank you for sharing your lathe refurb. Nice find.
I have this same lathe, in the Precision Mathews variant. At least it looks the same! PM 1236 is Lathe Model. Gives me encouragement that you can put an 8-inch chuck on the lathe.
Which one is shittier, princess auto or canadian tire?
Well done, great job.
I got my Koping so cheap I could’ve made money taking it to the scrap yard it’s 8000lbs of greatness 16”x10’ between centers metric dails inch and metric threading with inch lead screw which I guess makes since since metric threading is odd no matter what lead screw you have but all in purchase price new 7.5hp motor well new to me Baldor loading fee a new vfd and some wire I’m under scrap value still honestly if I were to ever rescrape the compound it’d be a perfectly fine machine as is it has some quirks tho
THANK YOU THANK YOU for doing this video! I have the Old Harbor Freight version (Gearhead 12x36) of that one, now Grizzel sells it. Have not had the roll pin issue, but this shows me how/where I will mount a DRO someday, that 8 mm (8mm), sized oilers, and more of the workings of my lathe in general. I need a better oil can though and help on that, I use a Goldenrod with a screw on tip a little recess in which I beveled an area for an 8 mm 'O' ring. I have in the past pushed in those balls and had them not come out. I do have a switch issue with mind randomly using the lathe it just turns off. Waiting for Grizzley to send me a new one (BACK ORDER!), my 3 jaw chuck was not worth much could not use a parting tool bought the 4 jaw 8" love it of course you have to indicate everything. I have Accusize 252-222 BxA I do to this day still do not understand the sizes! AxA BxA could you do a class on that please?
Never used a DRO myself, so I would have left that off, but well done for getting everything back together.
Hot Damn 86 thousand views on a lathe video.. your killing it MR. I have a 14X40 of a similar brand lathe with the SAME DRO setup. very cool.
In the future, if a cable is moving you should use a multi-thread cable, not a solid core one. If you want to use network cable, then use ‘jumper cable’ which is multi-thread, more flexible, and thus will not break. A broken cable can induce a meta-stable/erratic condition that is very difficult to diagnose
"thanks for watching" reminded me of SMA. Great job restoring the old girl.
As your tightening the Chuck to the spindle, use a rubber mallet on the face of the chuck to help it tighten and accuracy
Check the chuck to see if the one of the scroll pinions is marked. It with be the only one that will have accurate accuracy when the jaws are tightened. It’s called the nominated pinion, and was the one used when the jaws were ground. Good job on the lathe.
21:06 Wait...are you trying to get good at falling off a bicycle?
Machine has only cosmetic issues - the ways are in good shape. This is why one should not expect a huge discount.
Strange choice for DRO.
Accusize is more expensive than most resellers of Chinese stuff - they pretend they have a "brand" - they do not. Main advantage with them is quick response time to questions.
Was waiting for you to have a hernia wrangling the new chuck. 6" to 8" is at least 100% more metal to wrestle!.
You can always make an AC supply that is a bit high in voltage into a bit lower voltage by putting pairs of diodes connected in inverse parallel (each diode's cathode to the other diode's anode). The cost of diodes is minimal. Each pair of diodes drops about 0.7 volt without much affecting regulation.
Loved this vlog so much I subscribed! Thank you!
Same here.
What you are doing is exactly the job that my dad did for Battleground School District in Battleground, Washington. My dad has been gone 25 years but watching you do what my dad did was very interesting to me. It takes a whole bunch of knowledge and common sense to do this.
No need to mill off the bottom of the endthread. Open up the back end of the drillaperture and put in the thread from there. Nice piece of scrap though, shure got yourself some value there!
The flange stops the tailstock quill falling out if you wind it all the way out. I think you will find it was possible to shorten the tailstock thread by a small amount instead of taking the end off your chuck. When you have a Digital readout you loose some "length" of the tailstock. If possible adding clamp bolts between the saddle and the compound slide assembly. Rigidity is your friend.
Wait. Lol. Hold on a sec. So you're telling me you're a shop teacher, that teaches safety, whilst running a lathe with long sleeves? 🤔 Cool video though. Roll your damn sleeves up though before you become human hamburger meat, dude.
Good for you! I have a newer version of this lathe new from Grizzly. My head stock was full of metal chips from the factory. many people ended up changing all the bearings because of this. I would advise opening the top lid and at least taking a look and check the run-out at the chuck end of the spindle. I still love the lathe after all.
Rich
Cool video! I’m subscribed.
Not quite my battlefield but you sure made this interesting and educational. I learnt a bit out of this. Thank you.
Looks like a double pole, single throw, to me. A double pole, double throw would have 2 in, and 4 out.
Teach, your SHENWAI 900 is an outatanding lathe, you did well! I recently bought one andhave no issues
Usually scrap means the ways need scraping, did you need to do that.
I did not check the ways. "If you can't afford to fix it, don't measure it." They don't _look_ knackered, but we'll see if it's the machine that's the limitation, or my absence of skills....
@@GregWellwood At some point you have to decide what's good enough and just start using the machine. Not every lathe needs the Keith Rucker/Rotary SMP treatment. Much as I like watching a 72 part series on hand-scraping a lathe bed, I'm sure you have more interesting projects to pursue :)
A diagram on the tailstock end indicates the ways are flame hardened so they cannot be scraped like soft cast iron.
Pull your new chuck apart and clean all the grinding grit out of it! Typically they get a final grind and then go straight in the box!
Will do.
Brilliant job, thanks for sharing
I have the exact same lathe. I had the same roll pin fall out twice. The hole was slightly larger and would not hold the pin securely. I solved it with some airplane lock wire. It's a pain taking the carriage off.
I dread the day I have to source any parts for it.
