SNS 228: Toolmex 6 Jaw Chuck, K&T Mill Repairs

[Music] hey guys welcome back to the shop for another episode of Saturday night special so I think I have another good episode in store for you today we've got a lot of stuff to share with you and we're gonna we're going to start the episode off with a new tool in the shop and that's going to be a new Chuck and I'm gonna unbox it reveal it and we're gonna get it mounted on the lathe and we're gonna do some indicating and checking on it okay so we've got all that ready to go and hopefully that's gonna be a good share for you they're really excited about that all right we've also got some new developments on my milling machine the hernia trekker milling machine I've been doing a little bit of work on that and I had one of my friends at the motor shop here locally David he stopped by this week and looked at it with me because I I know that I have issues going on I had noises coming from the motor and I knew that the power is not riding on the mill so he came by I looked at it and we discovered what the problems were and what we need to do to correct that so I'm gonna take you over there close to the mill and I'll show you what what's going on and we'll talk about that a little bit as well okay what what we need to do and some more footage and some more machine work probably for the channel here and I think you guys might like that all right I've also got another update on this 13th edition Machinery's handbook I still have it I have not sent it off yet because there's been some changes with the recipients of this book so I'll just go ahead and tell you now so if you didn't see this is a handbook that was donated to me by Joseph Owens he sent it in and wanted me to have this book right here and last week I decided to give it away and told her by to send me an email and first one of emails me you could have the book and so the first email that I've got was from Patrick Collins and so I was gonna give it to Patrick Collins and then after I made that second video about him winning it and all the all the emails that I got Patrick emailed me and said that he would rather me forward this to somebody else rather than him and he just thought that somebody else could probably use this book more than he could so he decided to pass it on all right so I picked somebody else out of the emails and I got a lot of emails from a lot of people and as I said in that past video a wish that I had a hunter of these things that I could send to every one of you I really do but I only have this one so I can only pick one person all right so one of the recipients one of the emails I got was from someone called Ross bear and I'm just going to tell you a little bit about Ross bear but I decided that I'm gonna send this book to Ross he says he's a mechanical engineering student at Purdue University working at a machine shop in st. Charles Illinois I've been working up a small tool collection of Mike's CalPERS and other and all of the tools I need working on the Bridgeport and in our metrology lab I'm really looking to get involved in the industry when I graduate as I've always been passionate and interested in machining 3d printing and CAD and cam I've also been a teaching assistant at the Purdue B IDC where I run several hostels Lai's and a water jet and I'd really appreciate the copy of the Machinery's handbook as I don't have one and I'm working on a very small budget to pay for tuition for college and he goes on to just talking about how he likes my videos and how he he he considers me a role model and just has a lot of nice things to say about me there so Ross you sound like that you could use this book so this one is coming to you okay so I'm gonna get it in the mail now and get it coming to you and hopefully this will help you with your endeavors so good luck with your with your training they're into college and sounds like you're doing awesome you know volunteering and helping out others and I hope that you you go far all right and hopefully you're gonna continue to watch the videos as they as they progress as well all right Ross all right guys we got another new tool in the shop and I'm very excited about this one this is the first for me we've got a brand new six jaw chuck and we got the backing plate here that goes with it okay for the direct mount on my lathe and this chuck was given to me by KBC tools I've told you before KBC is a is a supporter of my channel they like to reach out and help me out every now and then with something for the shop excuse me but uh every now and then they'd like to try to promote one of their brands that they sell and in this instance they have this tool Mex brand that they sell you know tool mix they have machinery and they have machinery accessories such as chucks and things like that and they reached out to me and offered up a six jaw chuck for the lathes here so what we have is a is a ten inch or 250 millimeter six jaw chuck made by tool mechs and tool mechs is polish made always known as very high quality tooling every everything that I've ever had of Polish origin I've got some other polish tool holders and even some micrometer 's and they're always very high quality tools so this is pretty cool you know I've always loved stood after a six jaw chuck for the lathe and I've never even used one before this is the first time I've ever had a six dollar are gonna use it it is the set true style of Chuck so what you have is these these screws right here you have four of them and these are so once you have this mounted up on the machine whatever my nude amount of run out that you're gonna have in there what's usually going to have I'd say you know maybe two three thousandth run out sometimes with a scroll truck you can actually adjust this like you would a forge all using these four screws so that you can get this thing set to near zero run out so that's another first for me I've never used that before so let's roll this right over here and then we'll take a look at the the mounting plate the adapter plate now this is going to be the cam lock these are all the cam lock studs that go with the backing plate there these are the cap head bolts that hold it in alright so there's the d16 is my spindle mount for both the victor and the monarch so this can be used on either lathe this is going to mount to the back of the chuck and it's held in by three bolts you see you got these bolts right here on the chuck you got a male/female fit right there with a register and the three cap head bolts so I'm gonna go ahead and start getting this thing bolted together get it as one unit and then I want to get it mounted up on the lathe and start doing some check-in to see what kind of run out we get by the way it did come with the the Chuck wrench and I believe all chuck chuck rinses now come with the spring on there and personally for me I take the spring off because I don't like the spring on there got a nice smooth feel to it I'm liking that all righty well for all the guys at KBC that are watching I really appreciate this gift right here this is uh this is a very very generous offer from you and I know that these are you know expensive tools to buy and something that I'm not normally would be able to get for myself and that's why I like to you know accept an offer for something like this this is going to help me out and I like to share this kind of stuff with my viewers all right I'm the first thing I'm going to do is go ahead and get this cleaned up I want to put some wd-40 on there and just give it a little wipe down just try to get some of the grease off of it all right got that about as good as I'm going to get it seem like it's just that cosmoline whatever that is that they used the rust inhibitor has just kind of stained that face a little bit but I have got it I just been rubbing it and rubbing it so we're going to go ahead and get the studs installed now so I've shown these before on these cam lock studs so you have a groove machined into it that's that's normally where you line up with this face right here so you just screw it down in there until it's about flush there and then you put your cap head bolts in there I need to go get a and you go get a wrench for that [Music] okay alright so we're gonna do that six times and by the way this is the first thing I've done on my brand-new table right here and this is why I design it the height that I did is because it's very comfortable it's at waist level and I'm not having to bend over hardly any for this I'm just kind of standing here and just doing my work so loving all right just get him in the back a little wipe down here get rid of any of the grease that was on it and hopefully any of the lint I'll show you all right so you got your three cap head bolts there and this is going to be the mating face right here so I've already got it wiped down so let's see here I'll tightest it it's gonna be there you go wasn't bad at all alright I'll tighten those up with with another wrench but there we go what's looking like right there and these adjusting screws also used a tool meant ten millimeter wrench I'll just leave those all loose until we get to the lathe all right I'll tighten up the three bolts right here and then once it's actually on the spindle of the machine I can tighten them up again that way the machine is actually holding the chuck for me now that we got it mounted onto the machine I did the opposing or every other one on the studs tightening method start with one and just just lightly Snug it and then I skip one I do it in threes and snug those up and I go to the other threes on the other the three jaw Chuck that seemed to really help get it centered on there so we're gonna go ahead and put it in the low gear I'm gonna give these another just another pull make sure that they're tight all right well let's see let's see I spin we're gonna go 370 I can definitely see some run out on it there so we're gonna have some we're gonna have some adjusting to do on it so it looks like on our first in run out check their on the body of the Chuck we're at ten thousandths and over here on the backing plate I was showing one thousand so on that yeah one thousand so on the back of the plate so now it's time to start adjusting it here with these screws and see if we can get this thing dialed in oh I was going to check it on the jaws too so I got this round gage finish the one inch pan this should be nice and round we're going to chuck this up and see what this is show and see if it matches all right it looks like we're getting the same run out there ten thousandths on the on the pin so we'll go ahead and start our adjustments and see I don't know if it's going to make a difference if you do the pin or the body I guess we can just go ahead and start with the pin since where this would be considered the workpiece we'll start there all right let's see what we can do it's weird it's making it worse why is it making it worse what am I doing wrong here well we're getting there that's about two two and a half thousand right there so I'm having to kind of splitting the difference there I'm having to tighten up the low one and a half now we're talking half a thousandth looks like a half-assed ow tense you're looking at tents right there I guess I can put another indicator up on here and let you guys see it in in ten thousandths looks to be two to three gauging by that indicator let's see what the body is showing one thousands on the the body there and while I'm thinking about it I want to go ahead and make sure that all these are at least snug and touching there was two of them that we didn't really move okay alright so here's my tents in a rapid indicator very touchy there I'm showing three okay the indicator holders moving around a little bit let me reset this you see it's wiggling around looks like three tents is what I'm getting not too shabby so what we need to do is take it out and put it back in to see if we get repeatability now this is the one that's got the zero stamped up here on this opinion that's probably where the factory tightened it up and did their initial inspection after they built it so let's try that again it did not repeat we got one and a half thousand said it that it moved on me and why is that well that made a huge difference I tightened up all three of the pinions there and it brought it right back to where it was hmm that's interesting maybe that does make a difference there I'm getting two tents there goes there there went to three so I'm sure that I can keep keep adjusting these adjusters here on the Chuck backing and dial that in a little bit closer but there's really no need in doing that I'm gonna do it one more time I'm gonna see if it repeats one more time I'm going to go ahead and take it out okay let's go back in little snug all three Oh looks like we're getting five thousand staff time or I'm not not five thousands five tenths so don't forget we're reading a tense indicator which is super sensitive that's I'm wondering if some of this readout that we're seeing is jumping around is not in the actual bearings of the spindle here itself well I'm happy with that so it's showing me that if I want to repeat readings in here I need to Snug all three of the pinions for the scroll here that's cool well now that we got the new Chuck mounted up and we got it indicated pretty much dead nuts let's go ahead and make our first chips with it now this is just going to be just a piece of scrap steel I'm not making anything we're just going to make some chips so let's go ahead and slide it up and this is some 1045 steel it's chrome-plated and what we'll do is go ahead and snug it up and then we'll check it and go ahead and tighten all three put my indicator on here let's see what kind of run-out we're showing on this piece now jumping around on the ground marks of the chrome but it looks like it's within a half a thousands 150,000 cut like doing just fine let's go on there's two right here alright okay so there's our first chips with the new six jaw and it did great I'm loving it we had 150 and our 200,000 step to cut right there so it's a good quality Chuck and it seems to be doing exactly as it's designed to do you got your backing plate there so you can adjust it set set it true and we've got it within I say three tents you can definitely get it closer than that but I'm gonna leave it right where it's at so I'm liking it good quality stuff it's going to work really good for this lathe right here that's Victor Victor laid you know that you guys know me is running the the bigger four jaw Chuck so all the time and one of the reasons why is because of the holding power and be able to indicate it dead nuts true but also the big four jaws at work and on my monarch over there are so heavy I don't want to take them off unless I absolutely need to so this one being smaller is easier to swap in and out on the on the Victor lay so this one's going to serve very good here on this on this particular lathe so good quality Chuck I really appreciate it KBC tools for sending it out thank you very much this is going to be well used and appreciated around here in booth machine shop okay so you're looking at the inside here of the Kearney and checker this is a model 307 s12 and this is a seven and a half horsepower motor to come equipped on this model right here so in the past the the last video that I just shared last weekend if you didn't see that please check it out because we do some milling over here this this motor has been making a noise for a while not just now when I hooked it up but before when it was moved down here it was making noise and I knew that something was wrong but I just I just lived with it you know I just kept using the machine and my plan was to actually work on this and try to figure out what the problem was and fix it and correct it so I'm finally at that point you know I've had this mill for I think four years now are a little more and I'm ready to get this thing properly working the way it's supposed to be so I knew that it was making noise I had David come in the other problem that we've had with this mill is for the the knee up here you know I've got a whole rebuild series on this knee trying to get it working again and the motor that runs this knee up here with all the power feets has always been weak and I knew a long time ago why it was this machine is wired up for a 440 voltage ok high voltage three-phase power I do not have high voltage here I have low voltages I think mine is 230 three-phase that may not be right I know I'm just gonna call it 2:30 three-phase ok so this this motor here can be rewired back here it can be rewired it's got the schematic there on the cover all right we have this we have the info here and it can be rewired the wires that go to the front of the mill for the power feed motor the way they got it wired in is that it can't be rewired over here that motor is built into this knee over there so I knew that this thing needed a transformer in order to get the power to the front motor properly and then we could reconfigured the wiring here and after David came over and inspected everything I looked at it what he is suggesting that we do is put a transformer on the machine back here in the panel for both motors that will run the entire machine and just leave both motors configured at the 440 voltage okay his opinion is that that's that's actually going to be a better repair than and another reason too is that you know a transformer when he's looking up cost transformer might be $500 that's just kind of throwing a number out there well if you can get a transformer that around Bochum for $700 we might as well just do that okay so I've got an expense coming for that and for an install but that's okay because I want to get my mill working so the other things that we found here you probably already notice in this so this is the belt it's a serpentine style bill and I've been wanting to replace this so I've been meaning to take this into work we just took it off I'm gonna take it in tomorrow and I'm gonna see about sourcing a new bill hopefully gates or somebody that at work and can source this for me and we'll get us a new belt David at first whenever you heard this thing run thought that it was just the belt making all that noise so [Music] the belt is definitely bad and it is making noise but that's not that's not all we actually have some issues with our motor here we have some problems with this motor and we're gonna have to pull the motor out and go into it and repair it it's got some it's loose okay the in bells are loose and there's there's movement in the shaft so I'm gonna get you closer and show you so David you know got down here and the first thing he did was this see that motor ain't supposed to do that so you can move it in and out it's got in play and you can also it's hard to see it but so you've got a bad bearing fit in that in bell here it's moving so that's one of the reasons why the belt is tearing itself up and why it's making noise is the bearing I mean the the motor is bad so we're gonna have to tear this down and what I'm going to do is pull it out of here shouldn't be too bad we just got four bolts that hold the feet down to the mounting plate in here and then I could spin this thing around pull it out disconnect the wires I'll mark all the wires to make sure that they're that they'll go back in order I'll take some pictures and everything too and then I'm gonna send it I'm gonna take this down there to the motor shop and they're they're gonna clean it and test it for me and make sure that the windings are still good too now any of the machine work that needs to be done on it I'll be doing that myself I know this in bill is gonna be bad I don't know if the other one is bad maybe the shaft fits bad but all this will be you know I'll be doing that so anyway I'm gonna I'm gonna turn it on and let you let you hear it run you can just hear this bad right here [Applause] can you see it moving I don't see that pulley wobbling around yeah there you go so that's what's on the agenda there we got to pull this thing and rebuild it so it's going to be some more video footage for you guys but I'm ready to get this thing going and get it fixed and get this mill operating like it's supposed to be so that we can we could do some heavy metal milling so this is the motor that I was talking about this built in to this knee and this is what runs the hydraulics of the knee this runs your all your power feeds and all of your rapids as well I'll go ahead and bump the motor on so you can see this is the windings right here made into the casting and then the rotor is inside there spinning I'll fire it back up because I wanted to give you a demonstration of what I'm talking about so as I said that's the motor that's feeding this whole power need all the rapid speeds and everything alright if I want to move the table up you should be able to wrapping it up instead of cranking and that's what this hydraulic unit right here whenever you when you pull that up that provides hydraulic pressure to the rapids and pull this one up here alright see we're feeding the knee up you see it just bogs it's because the wire the the motor is not wired in right so it doesn't have this it doesn't have the power that it's supposed to so it's it's always had enough power it's always had enough power to traverse this way and then the same thing you know this side right here but back whenever I was playing around with some heavy cutting I did stall it out and trip that motor out before so you know I was learning that something wasn't right and we're on our way to get it prepared so whenever I whenever I get to the motor issues I'll be sure to bring it back and show show you what we find and and I'll show you the repair work [Music]
