this was purchased on eBay solely so we can take it apart and fit our Servo motor upgrade to it uh I'll go quick review on this lathe it's actually not too bad it is a typical three inch wide bad mini lathe it has the typical motor in the back uh it comes with it actually comes with a set of Cutters and of course the reverse Chucks also comes with metal change gears that's pretty cool uh first thing I noticed is it's going to need a bushing put in the uh carriage got the typical play everywhere and the housing and then we go to this is not switched it's just looks um where's the reverse switch Okay so this came with one of the inside nuts missing [Music] foreign there's your typical three-quarter inch three-quarter horsepower motor in the back the typical little skinny belt that usually blows we'll get a little closer look on that uh it does come with the um digital display for the spindle that's kind of nice uh but realistically this is just a typical mini lathe the lowest cost uh casting you can get the reverse switch is here uh we'll try it and see if it works but you got to take that whole cover off to switch reverse of course everybody's going to have the cover off all the time when they're using it all the main gears are already metal that's kind of nice providing they're not noisy uh we're going to do some test runs and stuff pretty soon so we're plugged in now we're going to go ahead and Power It Up we're in bright light displays nice and clear all right first thing I got to fix is that I'll have to adjust it so it doesn't hit [Music] um got a high-pitched electronic whistle and a lot of [Music] that's the motor screens so the motor is already on his way through that wonderful hang on let's check that get out these and see [Music] okay so that's the brushes and the motor the motors are already dropped from the get-go so you heard motor screaming I'm really disappointed about that because when I replace the motor and the control board on these with our upgraded version I can usually get about 150 dollars for the old motor and the old control unit and this motor I can't sell because it's too noisy remember I said this was loose this is about listening hear that remember I said the carriage was loose but look how loose it is that's that's like wow listen when I just knock knock that's actually normal for these uh many lathes that you have to rebuild them from front to back when you get one that's why I often tell people you know what rather than buying them anyways and then spending a thousand dollars to fix it why don't you just buy a lathe that's a lot better for a thousand dollars more and save all the headaches however my answer is always well that's all that will fit well there are other lathes you can get that are just a little bigger that are a whole lot better uh although unfortunately now the price is double what they used to be we have to take this apart too and see if we can fix that so we're gonna do that as well this way will be for sale when it's done by the way and it'll be nice as usual the little ways Allen that hold them in place are just kind of loose that way it's still everything runs when the retail buyer gets it they think everything's okay but nothing screwed together tight that's why it works they give you a set of Allen wrenches they're normal that way you can get in underneath here and tighten these next thing that's going to happen is when I tighten them this is not going to move there's supposed to be some grub screws in there so you can lock the two against each other to find the right point we're gonna try that we checked the bed with just a straight edge just a whole Square metal Square uh most of you probably have one for woodworking it looks okay by eye but the real truth is going to be when we get this so it doesn't wobble like this then we're gonna find out where the bed's straight uh in all dimensions so I took the first one off from under here three Allen or the short of course there's no grub screws at all put in there so as soon as you tighten this down it just locks it up if you try to use it the way it is these just come loose I suppose an option would be to clean them up and use Loctite uh you can also see that it's rubbing here and here and not here so this Plate's not even straight it's bent as well we'll probably surface the plates and put the grub screws in and go from there it's better again no grub screws set screws but at least it's running a little through so we lift this off there's actually a defect in this casting it's missing part of the metal uh it'll still work but you can expect to run into defects like that often this one is actually in the way they set up the sand casting I don't know maybe I'll file a complaint on that one too but I mean this this seller he's going to lose all his money twice over if I try to go at them with all the parts on this list he'll end up with two options well if he'll end up with a couple he'll you know we'll give you your money back forced by eBay and I'll have to go look at the listing maybe it says buyer pays returns well I don't want to bet shipping on the return because the shipping to return this is going to be half the cost of the lathe uh if not all the costs were delayed usually what they do is they offer you you know fifty dollars off or thirty dollars off and I hate to be this kind of person but you know when they're selling junk and they're not intentionally selling jobs that's what it is uh tell them to give you some money back usually you can get anywhere from Thirty to 150 back off the purchase and that'll help you fix it no matter where you buy this you're going to have to fix it if you buy it from Harbor Freight or if you buy it from Northern Tool or you buy it from Grizzly you'll find that they have stricter quality control and they'll be a lot less to fix although I got a Grizzly right over there and it's not that great so I surfaced the Warped one I cleaned up the one that was straight the grub screw holes were like really tiny I didn't have any grub screws so I drilled them out at m6 and threaded them and put some Allen set screws in or some balance screws same with the other ones uh I can turn these in and they can be the high spot and these the other three can be the clamping and that'll allow me to hopefully adjust it let me take a closer look maybe not Yeah well yeah it'll work it will just push this down from here a little bit and lock it in place now realistically perhaps a better way is to just fit shim stock in here get yourself an assortment of copper or brass shim stock and just put a thin one in first if it locks up a little thicker until you get it just right that's what I do on the big lathe uh and then it's locked in permanently uh until it wears a lot which eventually you'll have to change it I might end up doing that here we'll see if this works so it's a balance between these two which are pushing it away and these three that are pushing it towards it's pretty good there's a slight bit of looseness but look it binds it still runs good right here then it binds when it gets out here I think I'm going to try to loosen it up just a little bit right here if it was my lathe I'd leave it that way because I'm never gonna operate out there but somebody else might there that's pretty good how about play and too much foreign it binds right there but tail stock is going to be there that's a pretty good cutting range all right look at that there's well let's get the dial mic so we got two and a half thousands here if we move it farther out foreign that means this is two and a half thousands thinner here than it is here where this way is holding against it okay so what we did is we filed underneath here this flat because this is right against the V here nothing we can do so we cut the clamp inside we foiled and cleaned it up a little bit we didn't spend too much time we also changed this so it's kind of tipping at an angle a little bit we got two thousands play here and we got travel to about there then it starts to bind so this is going to be the cutting range of this lid we're going to do the back side the same way I'm not going to do a video on it update in order to fit this underneath the carriage these screws have to be these have to be short and this one has to be an allen setsku so that that gear can run right there okay we got that's well with intolerance for such a lousy machine all the knocking and locking is gone that was everything wobbling around and it was the half nut was banging into this by adjusting this we were able to make it run nice and smooth [Music] it's okay there too this is actually not bad this is a problem it's hard to turn and it locks up so we're going to work on that next first thing we're going to do is we're going to replace this handle with this little handle you can get this handle on Amazon there's two different sellers there's the one that has the little digit numbers on it I had really bad experiences with that guy he's in China he says he's here in the USA it'll be here in three days no it'll be here in 30 if you're lucky if you get in at all these are there sometimes sometimes they're not I used to make really beautiful handles for these out of aluminum they actually are much better than this but they take all day to make a set of handles and that means instead of handles would be eight hundred dollars if I was to actually charge what my time's worth this is 10 bucks so this is what we're going to use I cleaned it up in a little bit but this is sticking right there every turn and this is wobbling which means this shaft's probably been I'm not going to worry about it right now I got to get to the mod so we can Market the mod this needs a lock screw in here drill it thread it this Carriage needs a lock screw it looks like it's already designed for one it's got the hole right there uh to set this up estimated 45 I might Mark that off later we're gonna try to do the Chuck run out now so I'm getting ready to try to put some stock in there and I figure I'm going to Chuck up one of these carbide cutting tools that come with the lathe and look the metal goes out past the carbide chip which means this is just gonna jam and grunge it's not even going to work at all I'm gonna have to go fix that first got a piece of true stock at 20 millimeters OD it's definitely 20 millimeters through and see what's going on see if we can cut something with it see what what it looks like for a first try you don't look too bad it almost looks Center it might actually go this included in my labor I'm throwing that away let's try to make the first cut all right all right okay so the cutter is too high it's misaligning that car is going to be too hard no matter what I do because the cutter is too thick for which means you would never be able to cut anything with that cutter on their place so the carbide Cutters that came with the lathe will not work with the lathe because they sit too high up on the center obviously these Cutters don't go with the lathe in order to get it down I've put together a little piece of high-speed steel it's a real basic cutter it's thinner and I've made a shim so that it'll sit in there and it'll come down oh about a sixteenth of an inch with the shim and about an eighth of an inch without the shim and see if we can get a cut yet and stick this out a little farther man you imagine that somebody that doesn't know what they're doing gonna Gonna Learn to run away then they buy one of these things I've got about five to six hours already setting this machine up just to make it work before it's even gonna start working and I know what I'm doing you put an amateur on this machine which is most likely to buy it I don't know but if it was me you wouldn't want to be in the garage because you could hear me from three houses down and it wouldn't be good [Music] well we got it done I'm certainly not impressed but at least we got a cup [Music] a lot of vibration we have a chatter we have streaking at your motor found [Music] with that Okay so the lead screws too fast the Cut's too rough that's a rounded tip it shouldn't be rough like that okay we've taken the all the gears off so we can eliminate all the gear noise that you were Hearing in the previous videos [Music] that's the motor noise brush noise from the motor we'll address that later right now we're going to work on the good noise one of the two if they got this detent set in the wrong spot so these gears are chattering I'll try to move that detent up but I mean it's drilled pretty bad already I might have to replace the plate this is for a different lathe it's almost the same I can make it work so we drills that detent like I said got this sitting a little higher that moves this gear a little farther away and now the howl is still the motor that little bit of chatter you hear from the gear is just that that's okay next we're gonna do the other gears d then I'm ready here on and the first large gear for the lead screw you can always want to have some play in here I don't know if you can see that you don't fit these tight or they're going to be noisy they're going to wear fast but just a little bit of wheel bearing grease on it it's not slain-free grease it's what I got all we got now still is normal gear noise and of course the motor's still howling and result with metal gears all installed a little bit of Grease the pattern knife not the hell noise that's awfully loud that's all we're gonna get with the metal gear that I think I'm going to put a couple plastic ones in and eliminate the noise okay so we got a plastic gear off of grizzly they come with a three millimeter keyway we had to Broach it out to a four to fit it uh put that one in between the metals try to improve the noise and business days but wait so it's way better I don't know I still got that damn hell noise from the motor so we chucked in up a known true piece of 20 millimeter diameter Aluminum stock uh that I machined through before I put it in the leg set it up uh nothing else done to the Chuck we're finally back to working on a Chuck we have two thousands run out and I have to say for many of that's way better than expected most of them are three and a half to about seven uh so this isn't too bad we're gonna see if we can make it a little better it's supposed to be a Chuck Key Safety it's supposed to shut the lid off if you open it it's not let's see if we can power the lathe up yeah wide open just by turning it on with that up so obviously it's worth it first thing we're gonna do is see if there's a favorite single tightening point so we're gonna set it up this one is that's going to be number one right now so this one is just before it and two thousand and this one is just after notice it's uh on to it's four thousand three and a half thousand so tightening that one is worse indicator Mark that was this one so this is the only other one there's three tightening spots that one is one and a half thousand that's actually intolerant I'm not even gonna index it I'm gonna go with right there this is it so that is the mark first one the second one let's try it again even better that's one thousand steps to tolerance for commercial Aid actually so we're gonna Mark that indicator first one second one so we're gonna put a t right here telling me this is the one you tighten it with so that's marked as a t next thing we're going to do is we're going to double check these and instead of just having an indicator dot we're going to put the actual two counts that go in so that should be one two and three that's where it came originally so they probably did some kind of Turing before they shifted okay so we labeled the Chuck Jaws three two one tightening torque Center didn't index it didn't need to we're set up with a piece of stock it's inch and a half I believe and we're going to do a test cut see what we come up with and of course there's going to be a little bit out of round when we first put it in that's kind of normal because it's not a true stock in the first place [Music] we're actually starting to see some performance here [Music] [Music] [Applause] [Music] foreign that's still too fast I don't have the right gear to change that we're gonna do another cut Ting speed should be about 800 we're going to set it up at 1300 . we're gonna put this in one two three four five six thousand and see what it does [Music] okay that's about the max I think we're gonna get out of it it's still got a lumpy Ridge on it that would be fixed by better cutter maybe tighten up the bed a little bit more definitely some locks on the carriage so you can lock whatever piece is not moving so it doesn't vibrate or shutter there's a vibration noise but this lathe is at the point where we're going to consider it done as the average user would get to and then next we're going to do the motor mod I will continue it with this video but it will be a separate video because it's going to be instructions for upgrading the motor on this lathe
