SNS 242: K&T Electric Motor Shaft

[Music] hey guys welcome back to the shop for another week of Saturday night special tonight we're gonna have quite a bit of machining footage for you we go ahead and we get started on the K and T electric motor shaft right here and we're gonna go ahead and get this shaft completely roughed in and then what we'll do is next week I'm gonna set it back up and lathe and we're gonna we're gonna finish it so tonight you know we'll be roughing it in letting it cool and then next week we'll finish it out probably finish all the turning and then putting the keyway in it and it's got a couple holes drilled through it as well so I know a lot of guys have been excited about getting back on this project and I'm excited about getting back on this project too because I want to get this done get the motor built and then try to get this K and T mill back in running operation so that's going to be the content for tonight for for this video okay I do have another Machinery's handbook we're gonna give give away and also want to give a couple of honorable mentions as well but let's go ahead and do our book giveaway so this week what we have is a Machinery's handbook that was donated to us by Mike Ray okay and Mike gray can be found under a practical metal YouTube and he's also on a practical machinist as well I love his sticker I just love that I love the old-school welder look right there got the traditional pipe welder hood you know so he sent me a couple stickers and Mike we will get your sticker over there on the on the cabinet but uh Mike was very generous and he actually sent several of these Machinery's handbook so I have a few of them to give away from him alright so this is the 15th edition all right here we go there's the 15th edition by the way Mike is from Columbiana Alabama and there was the previous owner of not really sure how that last name Thielen or Thielen dick dick theland from New Britain Connecticut I believe is where that's from nice book all right so we now have a total of one thousand two hundred and twenty six entries into the missionaries handbook giveaway and I used the random number generator it popped up with a number of 132 so I went to the list and the winner this week is Ron Enders from Rotterdam New York so congratulations Ron you got the 15th edition book right here all right so Ron answered my two questions his favorite content is machining welding and hydraulic work cool and then what he'd like to see more of he just says that he's happy with everything that I show and he loves the projects that I take on here in the shop and he also loves the metal izing or the spray welding so thank you very much for your answers there Ron I appreciate it and I will get this book packaged up and coming your way real soon okay I wanted to give a couple of YouTube mentions out there to a couple of channels that I think are well deserving of some of you guys some of your subscriptions and views but a first one you might you might already know a fireball tools that's Jason over there fireball tools he's the one that invented these really cool welding squares right here you got the Mega Square and then the monster square right here these are the mini versions by the way but just showing you you know an example of some of the stuff that he does Jason unfortunately a few months ago he was he was working on his YouTube channel he was trying to switch it from I think from a private channel to like a business Channel and something really odd happened that particular day and whenever he made the switch YouTube actually deleted his channel completely it just wiped it out and he was not able to ever recover that previous channel I think he had between seven and eight thousand subscribers that he just instantaneous so Jason started a new channel you know again fireball tool and he's been trying to slowly gain his subscribers back and I really appreciate if you guys would go over there and and check his channel out Jason isn't his YouTube channel isn't just trying to sell squares that's not what he's trying to do with this channel he sells squares but that's not what his channels about he's actually just like us he's a fabricator and he likes to build things he likes to do projects in his shop so he's been doing more of those type of videos of actually you know projects building things and he's got a lot of ideas for things that he's going to build and share on his channel you know and he just utilizes his tools in those videos and of course he'll use it whenever he needed where he needs to share something new that he's coming out with you know but he's just a really cool guy and I really appreciate getting to meet Jason and hanging out with him and both Atlanta and Texas and I feel like that we've made a really good friendship there that's continuing to grow and I actually plan to go and visit his shop sometime next year he's up in Spokane Washington and he's got a nice shop that he's putting together there and he's trying to bring more of his tooling productions in-house doing a lot of it himself but he's really building up a nice shop there where he can actually build some cool projects and put there on the channel so be sure to go check him out please and give him a subscription he's I know he would really appreciate it for all you guys that lost that subscription because of YouTube you know go over there and hit subscribe again and check Jason now so anyway Jason oh you watch I really I really enjoyed hanging out with you over there in Texas and you know just getting to chatted up about shop Talk and and these tools and projects that we want to do and all that stuff and that also your brother Jameis is really cool meeting him and I look forward to hanging out with you again at your shop okay another YouTube channel that I want to give an honorable mention tube is the Museum of our industrial heritage please go and check out their channel and I've been in contact with these guys for quite some time Scott Conte he works there and Scott also has a Instagram page s.pd tool and he works at Welles tools that makes taps the same Wells that you might know that you might see you know Wells you know tap and die or something in your box he works there they're still in business making taps but anyway Museum of our industrial heritage they're local up in Greenfield Massachusetts where Greenfield happened I was from and they have some really cool videos on their Channel you know some old movies of different things involving manufacturing and metalworking and cutting tools and things like that they have some videos up of measuring tools like rolls micrometer different types of cutting tools they they have a really cool movie on green fill tap and dye a movie that they had made back in the day this is you know decades back and there's another video on the geometric die head but they have a lot of really cool interesting videos and I think I think you guys might enjoy it so please go over there check out their channel Museum of our industrial heritage I'll have a card up here and I'll have a link down below that you can click on and I really look forward to visiting with them I'm hoping maybe next year I can take that New England vacation that I wanted to do and go by and visit the people I stare it and maybe get the toilet stare at plant and also go over there to a green fill mass and visit the museum there as well probably go north to Vermont I think it's in Windsor where the precision Museum is that I want to go there as well so that's sort of some of the things that I had wanted to do whenever I go up to Massachusetts I just I don't know when that's gonna be but hopefully we're gonna get to do that next year so Scott I really appreciate you know talking with you and you guys continue to bring those really cool videos to your channel and hopefully some of our viewers here on my channel will go over there and check you out and you know give you a subscription and give you a like because those guys over that Museum are really looking for for some views to know that you know the effort that they're putting forth into preserving these old movies is as well appreciated okay so go check them out I've been excited to share this new tool acquisition I just got it in this week so what we have is a is a read 108 vise this is the 8 inch jaws up here and just showing you right there we've got their gutter 8-inch jaw and this thing will open up to 12 inches plus so you probably wondering what the heck's going on with the paint job there that is the beautiful artwork of my friend Andrew Alexander at blacksmithing tools on Instagram so when I was there visiting his shop in Texas in Dallas I got to do a shop tour his place and which it's gonna be a video coming out I haven't got to do it yet but anyway he's got a heck of a collection of these eight-inch Reed vices I mean he's got him just I mean you trip over him going into a shop he's got some many of them so I was I was really hammering on a part about selling me one of these because I've always liked these eight-inch vices and they're just you can't find them you know only guys like Andrew can find these things it seems like and I've been wanting to buy one for the shop as a project here so anyway he finally offered to sell me this one he calls this one the the belt buckle Reed because of this the way they did their logo right there traditionally you know Reed was casted in like raised lettering like right here and I don't know when they did this it's probably I don't know 50 60 s if I had to guess but anyway he finally contacted me and said that he would he would sell me the belt buckle Reed and I I offered to buy it so that's what I did and he he was so mad at me for agreeing to buy this vise that he decided to paint it pink so he went Boston paint sprayed it pink just because he he didn't like that I agreed to buy it I guess he thought I was joking with him but I really wanted one so it's in really good shape and I plan on making this a restoration project for the channel and what I want to do is not only repaint it a proper color not pink I want to take it apart clean it give it a really good paint job maybe do some detail work right here and then I want to build a big heavy massive pedestal for this vise I saw one at Andrews shop that is ultra rare pedestal that was a casted for one of his other big 8-inch vices and I'm gonna kind of use that as sort of a reference on how I want to build a pedestal for this I want it to be at least a thousand pounds I probably probably gonna make it bigger than that because the pedestal that andrew has that I'm modeling off of he said is a thousand pounds so I got to go bigger and I got to go heavier so I've been kind of rounding up some materials to do that and it's going to be a standalone pedestal that you know that'll sit on the floor somewhere that'll have that sitting on it and it'd be nice and heavy so you can't bump into it knock it over and it'll be a proper height this is a little bit too high right here so we want to bring that top of the vise down some you know around thirty-five or whatever inches so anyway just want to share that I was excited too by getting this and Andrew thank you very much for the paint job dude I was kind of messing around with the vise the other night whenever I got it up here on the table so Jahl still seem to be in pretty good shape as far as the serrations go but took this pipe just an old piece of pipe and you can kind of see the the vise marks along it it looks like it's got nice parallel grip to it I'll go ahead and we'll show it again you can really crank down on a vise like this to hold something give it some a bond fork you see it's holding pretty good got a lot of power got contact all the way down the jaw right there so happy about that but this is something that I look forward to doing here in the near future is being able to give a proper restoration to this vise we're gonna go ahead and get started on this shaft this is for the K and T the current record milling machine this is out of the motor and if you if you didn't catch this before this one's bent down here on the end plus the bearing journals or wore out needs to be fixed it started been fixed once before it's been welded up so I decided to make a new shaft so we've got a piece of 4140 ordered right here I bought this from McMaster car and what we're going to do is go ahead and get it cut to the right length to start with so we'll just measure the length here I got some B blocks we'll set it in put that magnet on that end there I've got my rule all right so we're at 18 inches and 1/16 so we'll go over there and we'll cut at 18 and 3/16 I'll give us eight minutes on the end of it their face face the ends check that yeah 18 and 1/16 all right this is gonna be a pretty straightforward job so we'll take this piece of stock right there cut it to the right length we're going to face the ends face and center drill the ends and then what we'll do is we'll we'll turn it will rough it we're going to rough it first rough one end down all right flipping around rough the other end rub the center down and then I'll let it cool and distress if it's going to move any and then we set it back up and finish one end finish the other end that kind of stuff so once we finish the turn and then we'll have one key way that we got a mill here and there's two holes drilled in and I believe those are for the fans so let's get started put some of this corrosion inhibitor up girl more always seems to be tight we're gonna use the victor lathe for this job and make use of this new six jaw chuck I want to really see how it does for shaft work you know having the ability to dial this thing in so we're gonna give it a try you usually use the four jaws but we'll see how it goes this time around we're gonna start with the ends getting it faced center drilled on the end and then we'll work off that center there we'll see what kind of run out we're getting here about a thousands to a thousands and a half okay not bad [Applause] [Music] [Applause] now we got our one side face there I'm gonna come back over here and get a measurement on it so I know this isn't face yet but we are showing 18 and 1/8 so we want 1/16 off of it what we'll do I'm gonna go back to the lathe and I'm gonna face half of that so we're gonna take like 30,000 off that face come back and measure it again and I'll get a more precise measurement on how much needs to come off of that face that overall length right there isn't super critical you know if you get that with an SI 1015 thousand s overall length you're gonna be fine what you want to maintain here not only your your journal size is here but you know if you maintain this distance between here and here you'll be good to go if you're if you're sticking out five or 10 thousands on the end there on a shaft like this it's not going to hurt anything you just want your Center distances to be right [Music] alright let's go back to our B blocks and measure it out again alright let's get a measurement on this like we're gonna scale it out now I was going to say that I would normally measure this with a vernier caliper now I have some 24-inch vernier calipers but I keep them at work use them they're down there quite a bit more than I do here and so I just don't have them here and I do have some 36 inch vernier calipers I could use but I don't feel like lugging those things out for a short piece like this so I'm just gonna use my scales the scale or rule is gonna get you close enough all right that's gonna get you where you want to go so we should have approximately a 30 second to come off based off that last cut I took a 30 thousandths but we'll we'll figure it out here so let's see so I've actually got a little more than that thirty second so what I need to do is flip it over onto the sixty-four side remember we want to finish this at 18 18 and 16 I know you met you guys are just going nuts right now I love it alright so what we have though is eighteen and seven sixty fourths of an inch there's our length right there I'm gonna double-check that come on get my magnet yeah 18 and 764 so that is going to be believe it two-point 109 let me check my chart so point 109 should be around 47 thousandths - point 0 6 - that's a 16 there yeah so 47,000 so that's going to be our our cut length there on the end and out of that will put us at 18 and 1/16 of an inch or 18 point o 62 so what we're gonna do is we're gonna touch this thing lightly like that I'll take 45 [Applause] thought I'd show you the run out on this end since we did the other looks to be the same about one and a half thousands total what I'm gonna do on this end is just skin it so makes to make the OD true at that Center cut so that I flip it around and chuck it on that in there and it's true [Applause] and we're gonna try this carbide insert here this is a Seco TP 3500 and I'm gonna try it for a roughing cut and see what kind of chip we can get if I don't if I can't get a good chip control with that we'll swap it out to another one and give it a try come down here we tighten our Chuck okay we're gonna go ahead and start roughing this shaft in and that's what I'm going to do we're gonna rough in both sides rough in the center and then let the shaft cool and then set it back up alright so our first link here from the end I just set a zero there's gonna be 64 millimeters back to our shoulder and then our diameter is going to be 35 millimeters but it's going to be size the quarter when we liked it like it supposed to be for our chart so we're also going to be using my Noga this is the Noga mini cool a lot of questions about this I use this at work because on the pacemaker I do not have flood coolant the only flood current layer that I have is my monarch over there so that's why you see it over there sometimes but this works really well and I'll show you how it works first thing I want to do is go ahead and make a mark I'm going to use the blue sharpie right here and just kind of paint we're about what that tools at it's just a little little witness mark alright so it just kind of gives me a reference as I'm coming up to that area right there so about the the Nova cool I've got it plugged into my air line I've got a bucket behind you with the cool mist number cool mist formula 77 mixed with water alright and then the up guy that just kind of flowing right on that tip so it serves two purposes it's keeping this tool and this carbide cool just like flood coolant will and it also helps keep the temper the temperature of the shaft down as well so you can regulate the amount of oxygen you want going through it the amount of air I mean you can also regulate it here how much coolant you want coming out of that you can really flood it or you can back it down try to keep it somewhere around there it also helps keep chips blow it away from the chip the the tool there as well so let's go ahead and see if this slave is going to handle some cutting it's been a while since I've done a shaft over here and touch off and we're gonna try like someone ate touch nothing nothing heavy-duty okay that's looking pretty good right there a little bit more cooler and it's looking pretty good actually you can see how well that Noga cool works you know versus flood coolant because I don't have flood cooling over here but it gets the job done I use this at work doing those big heavy 4140 shafts and when I'm done making a bunch of heavy cuts I mean I can grab this with my hand it's it keeps it nice and cool so we're starting out at two inches and we're becoming down to about one and three-eighths that's the same thing as 35 millimeters so I'm just going to take some 1/8 cuts [Music] all right so I'm getting down to my final roughing passes now I'm gonna finish this thing at about a sixteenth over so I'm shooting for one inch for thirty seven one in 7/16 so that's gonna that's about sixty towel of what we need to take off there 62 I mean so I don't know how this is going to do once I back off on the cut we're going to take 30 thousandths it's 30 let's see if it breaks the chip now see I don't want to break a chip very well but that'll work there I'm just trying to eliminate having to change the insert there's the my common uses a brown and sharp one two two and earlier I checked it against a one-inch gate block and also a one-inch when it's pin gauge as well and it's reading right on so let's see what we're miking right there all right so it's 478 so that's forty forty-one thousand sore so I'm just gonna take forty thousands and that's gonna be our finish pass there forty look at you know I can't believe that it's gonna do that to me on the finish cut man slow it down it's okay this is it's a rough - rough surface so we've got to finish that in let's go ahead see where I hit it at all right 434 I'm gonna see if I can clean that chatter up all I did was touch off and just dial in like two or three alright that makes me feel a little bit better right there ok so let's take this tool out and we're going to put our chamfering tool my MCH nn and we're gonna break those edges there this morning break them before I tighten that Chuck up all the way I want to bring my Center back up to it and I always try to keep my tail stock stick out as short as possible so I'm going to reposition this tool up here to where I get a little bit of room left and then just bring my tail stock up all right clean the center off all right now we'll go ahead and snug up our six jaw here see what kind of run out we're showing right here behind our turn journal 1,000 so it's it's the same run-out that we had showed earlier measuring on the OD and a random place after chucking it so it's looking like we're gonna be pretty good to go for roughing so yeah let's go ahead and roll with it there's our old shaft and I've jotted down the measurements that I want to make this two on there and that's just for a quick reference I'll have to continue to measure it I've added just a little bit on this shoulder right here because it looks like it's done some rubbing I'm not really sure but it looks like it's got maybe a little bit of wear right there on the shoulder so I've added just a little bit about 15 thousands to their gonna make it eight inches ninety three that's really close that's between 105 and hundred six millimeters I believe and then so this that length right there from here to this shoulder is going to put us at seven and 3/8 all right so there's our there's our diameter that we're going to be going to again so it's going to be the same as the other side's 35mm but we'll have it sized properly right here for our bearing Journal and then we'll have it slightly under from this point on it fits the you know you've got the pulley it goes on there and a fan that goes there as well it's gonna be really sweet once I get that new all dro hooked up on this lathe and I don't have to do it like this all the time so I'm using my starett hook rule here hooking the end and then we're going to line up the tool bit right on the seven and 3/8 line right there and that's going to give me a little bit of material to work with in between the shoulder links so I'll actually use my calipers and make sure that these are faced in like I want to you know and if there's a little bit of there's a little bit of extra shaft sticking out the shaft in is where is where you're gonna want it right there so let me just make sure that I have this where I want it and then we'll go to our cut all right it's looking good right about there seven and 3/8 so I usually double check a lot of times once I get it set where I wanted I'll come back in there and just kind of refresh and make sure that I'm on seven starting from one side and then 3/8 so be a third line in there so let's go ahead and let's go ahead mark it with our sharpie let's go ahead and set our indicator right here I'm going to set a zero so that'll be our stop just come up and touch it all right let's see if this thing is going to handle 600 rpm we've got our cut set and sometimes it does that run on the start [Music] so on this other end you remember how we had our chatter problems because I had backed off on a cut was only doing 30 so what I want to do now is I'm gonna split this into two finishing passes we're at inch and 3/4 on our sizing so that would be you know the to roughing cuts at a eight to an inch depth plus the sixty thousand so we're at one-inch 750 right there I want to check this in and see what kind of taper I'm getting and it looks like it's machining right on inch and 3/4 all right so that's gonna leave us five sixteenths 312 let me just do the math real quick so point seven fifty - point 437 okay yeah so five sixteenths is left / two cuts so we're gonna take 156 let's see if it'll handle it okay [Applause] now you can see starting to get a little bit warm now if that mist was not spraying on this thing would be very hot at this plant now I want to go ahead and Mike it and see if I'm correct on my sizing but we're just gonna finish it out all right so it's 75 85 95 92 I've got 5 92 so point five nine two - point four three seven is one hundred and fifty-five dollars right where we want to be so we're going to take one more roughing cut one fifty one fifty five so there's a hundred there's fifty and then there's five okay [Music] [Music] we're at UH 439 so I was off by mm my name is 439 all right good let's go ahead and rough our Center so I'm up against the the jaws here so I've got to move it back a little bit I'm gonna go ahead and loosen the tailstock and just push it out that way what I want to do is make sure I leave myself enough room here I can get my chamfering tool in there it looks like that'll work right there all right so let me start with mine marked opinion Snug it there now I'm going to read retighten up the tail stock here go back to chuck make sure it's tight let's see what the indicator is reading right up here on this journal now that I moved it taking it out 1,000 it looks like it's repeating well this chuck is so we may we may be able to finish everything right here in this Chuck I'm gonna finish this journal here at 1-inch 820 that should give me a little over 60,000 s to finish it down so that's a 180,000 so I want to take off so I'm going to do 90,000 cuts and I'll see how they [Music] let's step cut there that's why it's trying to string out a little bit more [Music] it's 9:10 that one's 9:10 right there so that's gonna leave us with what 90 90,000 so let's do the math real quick point 9 10 minus 0.8 2090 I just like verifying that instead of doing it all in my head all the time so let's do another 90,000 [Music] [Music] [Music] see if I hit my one inch 821 in say 20 we did good there when in sake 20 all right so I just need to deburr that by the way you see this right here that nozzle SATs dripping so I've got the bucket of coolant sitting on top of the tailstock so this will siphon out if you don't close this I mean you just disconnect it from there but it's always good practice to go ahead and shut that nozzle that nozzle all the way off whenever you're done using it there well what we're going to do we're going to end this here I'm going to take this out of the lathe I'm going to put it on the table I'm just going to let it cool down and then so when we come back we're gonna start our finishing process okay we'll see you then [Music] you
