Shop Talk 5: Threading Inserts, Monarch Headstock, Cutting Oils

good morning everybody I want to wish all of mine us viewers a happy 4th July and hope you're having a great holiday weekend I got my little American flag flying right there so today Sunday and just kind of taking it easy this weekend but still trying to get a little bit of work done out here in the shop and today I wanted to make another shop Talk video for you guys and answer some of the questions that's been asked on the channel different topics different subjects that have come up so I'd like to go ahead and talk about a few of those so will will go ahead and jump right into that I've got a few things I think you're going to like and tomorrow I'm probably going to be doing some barbecuing but all right so let's go ahead and talk about a few things I want to give you a little review what we're going to discuss so had a lot of questions about threading we're going to talk about some threading inserts different styles I keep getting asked about cutting oil so I'm going to give that a mention and down there at the monarch I've got the headstock cover off and we're going to take a look inside there and we're going to talk about that so first thing that I'm going to go over real quick here is some threading inserts there's different types of threading inserts and people have asked me about the different ones and I don't know everything there's a know about carbide threading in search or carbide inserts in general but I can give you some of the stuff that I know and that I have right here okay I made a comment the other day I don't remember where I was it might have been while I was threading that rod might have been that right there when I was threading that for the parking attachment I made a comment about old school style threading inserts which is this style right here that's what I was commenting on this is more of an old-school style this is another one right here that's just a bigger size that is the 43 Envy size I believe and this is the three 32 I'm sorry I got some of these inserts just this past weekend from Tom Lipton he had a couple pack cities this is a TN MC 32 MV so he had a pack of some of the encoded inserts which is awesome and he just let me have them so I needed some more of these that was great now this here is if your is your more common type of threading insert and that is what I like to consider a lay down style of insert I've even seen it called that lay down style you can see it's more flat and this is often considered the on edge or stand up style of insert what I have found through my experience my personal experience is that this style of insert here likes to break very easy the tip of it just always wants to just snap off whenever you least expect it and it gets very frustrating when you're trying to get something done you got to keep changing the insert because damage keeps snapping on you're breaking I seem to find that this style of threading insert to lay down style works better and it lasts longer the cutting edge itself I don't know why but it just seems to work better now this one's messed up the pad underneath it should be supporting that carbide insert so I need to replace that pad but it still works this is one that's been around for quite a while this is an israeli-made tool maybe it's Carmack's I'm not really sure so that's the inserts for this holder right here so I said this is a TM c-32 envy is the size this style of threading insert is this particular one is a 16 er I believe it's 16 er AG 60 60 would be the 60-degree angle that's that's cutting this since are here which is the stand-up style that would be a TMC 43 in V alright so I've got a few of those still all right so let's move on to we'll go with the top notch right here I mentioned this top notch this is one that was given to me right here and top notch is more of a kinder metal style although everybody's making them now thinking of metal started it that's a look at the insert you got two edges and you've got one clamp that pulls it down and it's important to remember that there's a right on the left with all of these inserts so like I pulled something out the other day to use on this and it was a left-handed meaning that the the angle that's pressed into here that's molded into it it's for like say a boring bar or a left-handed tool which would would be mounted on the other side here so you have to have the proper right or left hand to match the tool so these are some inserts that I got at the back I forget who it was somebody had given me these so we got four good top notch inserts right there I believe this is a 300 size you have like two threes and fours just like these other inserts and that's the subject we'll go into later kind of breaking it down even further okay so that's the top notch and then you get into the threading bars which also uses the the ER style of threading insert just like this one only it's on the board bar and again you have to make sure you have the proper right or left hand on this style bar like I always use that's a left-handed so here's the inserts this is the Seacoast snap tap that goes on this big bar right here and that's a 22 nrn 60 and back whenever I bought that bar me and dad bought it we bought like two two or three packs these inserts I don't remember maybe it was twenty inserts and I've still got a bunch of these things because I just can't kill those inserts man they just seemed to last forever so I've got the smaller size I believe this so this would be the 16 size right here also a Seco snap tap and then these are two other ones that I acquired last year that are brand-new that I haven't used yet that are left-handed I think Tom Lipton likes to use this style of threading bar he likes to run it running in reverse and pull it go in and then pull it out and you can see that's what the pad supposed to look like underneath it so it supports the cutting edge so these two bars right here will actually use this insert right here I can use this same insert on those bars that's pretty cool OSS sort of like a just a quick general crash course on some threading tools right there these are probably some of your most common everyday found when I said old-school with this these are being less common I don't think a lot of people are making these inserts now I know kin of metal does not make this style of insert anymore so you have to go to other sources I would recommend I think the best ones that work or the style right here the lay down style and then after that I would go with the top notch the the great thing about a top notch is that you get grooving tools you can get they make them in radius Acme all your other different size of grooving and threading that you need you can get in top knot style okay so hopefully that helped out a little bit on the some of the threading of course if you have any questions on that feel free to leave a comment and let's go ahead and move on so I've had a lot of people asking me about cutting lawyers what what cutting wall do I use this is a good example of it right here this is what I use at work it's easily it's you can get this very easy from any industrial supply it's the rigid brand premium dark thread cutting wall that's basically the same thing that I use here in my shop the stuff that I have is was an old Exxon product that's been discontinued for a while it's called Penix in 47 it's a sulfur-based dark cutting oil and it works great on just about everything except for you can't put it around copper I don't I don't know if this one if that was if this is saying with that or not but I don't think you can use that on copper either correct me if I'm wrong so dark cutting oil you know just pick you up a jug you can go to the hardware store and get some ace brand or whatever and use this stuff it works great you know I'm not going to say which one is better than the other it's just you can buy this for kind of cheap you know gets you a little quart or a gallon size it'll last you a long time if you guys don't like the smoke that dark cutting oil puts off you can get anchor Lube I forgot I took that cap off you can use this anchor Lube right here this is some that stand I believe Stan give me this jug a while back and you can call up or I think you can look up anchor lube maybe give them a call they will send you one of these samples for free and this is good stuff because it doesn't it's water-based and it doesn't make any smoke it will steam a little bit it won't smoke up your shop and a lot of guys are liking that I really like anchor lube for tapping it works really good and then this is just another one that I got around here made by Wilton rapid tap that's good stuff too it's just got a lot stronger smell on your on your fingers and your machine and stuff when you get done using it all right so there's there's sort of an overview of some of the common cutting oils get you some dark cutting oil okay so the next question that I've been asked a lot you guys seem to really enjoy how quiet the monarchy is so I'm giving you something really special here I took the cap off of the headstock here and we're going to take a look inside the monarch I don't think I've ever shown this before so there is a peek inside of the the headstock and one of the one of the reasons why a lathe like this runs so quiet it's because of helical gearing in there that is a lot quieter smoother running gear than a straight spur gear a lot of machines I think some of the newer machines are made with spur gears which is a straight tooth versus an angular pattern so that's one of the reasons why it's so quiet it's some of the some of the gears run down inside the oil so you get lots of lubrication on the system as well as an oil pump that pumps oil up here to the top to the different areas the bearings and such so that's one of the reasons why the the machines like this are so quiet they were well engineered I did a lot of research on them and and Monarch did a lot of research and study and wanted to build the best machine that you could buy anywhere in the world you know this was back in the you know the the olden days the the war days and before that they really put a lot of effort into their machines and this machine right here was built in 1942 so just goes to show how well these machines are built and engineered we'll go ahead and turn it on and I can't run this thing up fast because it's going to try to swing all back here but all just kicking on a little bit you see here's the clutch mechanism work I'm pushing down on this right here and see the oil really really sloshing around right there so a lot of people asked me - about that home and that's coming from the drivetrain the motor down there in the bottom which is it's in the bottom of the Machine and it's transferred up through this built system right here the motors down there and it comes up you have a clutch right here and that that noise that you're hearing is through the motor in the clutch I've never investigated as to why it makes the sound and why it goes away when you turn it on though but that's kind of giving you an idea of what's what's happening there good so that's going to be it for this episode of shop Talk and I hope you guys enjoyed that and again hope you guys have a great 4th July weekend leave me some comments if you have any questions and suggestions on other subject matter in the shop leave a comment let me know alright see you guys later
