In this video I remove the Spindle from my 1955 Monarch series 61 Lathe. It is a series 61 , 16 with a 18.5 swing x 72 Spindle needed to be removed in order to repair a broken shift fork.
👍 Thumbs up on your mix. I am a hobby machinist and worked on a couple of belt driven lathes. I own a gear driven lathe that needs some work so when I retire I will dig into it. I feel a little more comfortable after watching your channel. Thank You! Ric
John, I appreciate you watching the videos. First time I came across that style snap ring was probably 1981 1982. The large versatile tractors used them in there transmissions. Gary
Hey Gary Longer videos with details and thoughts as you work are much more valuable to viewers who want to do similar work. Thank you for sharing step by step. Capt. Art
nice work, the longer the better for my taste thanks for taking the time, I also watch max at swan valley, he did a great series on a smaller lathe, complete maintenance a few years back great stuff it really helps to see it done so you know what to expect . I really appreciate it
Thanks Gary: Another opportunity for me to marvel at the engineering that went into these wonderful old machines. My favourite section was the lead screw gear box and its amazing looking mechanisms. Off to watch part two now. BTW: Long or short videos are great for me, but your detailed videos contain gems like how you plan to rotate the rubber snubbers to reset the detents on the speed selectors.
beautifull machine and dismanteling, everythings still loosed up , one thing ,I dismantle many machines and gearboxes and never ever saw a machine what ever contains oil, so completely dry. the gears the bearings and the casting all completely dry. great work.
Love the Monarch lathes. Definitely on my bucket list. Great explanation of the disassembly of the spindle and operation of the controls. Thanks very much for sharing Gary.
Gary I am in the long videos camp, I figure if people want shorter videos they can always play it on 2X lol... You can always speed up a video but you cannot watch content that didn't make the final cut, so my vote would be keep em long!
I am sure it is a petty thing on my part, but I am so glad to see you clean the crap out of the threads before running the lock nuts off. I can't count the times I have seen people try to restore things and make the job so much harder by not cleaning rust and crud off shafts and out of threads.
Thank you Gary for this awesome series!!!!! First person I've found that simply and visually goes through the steps of removing a series 61 spindle. I have Series 61 14 X 56 that is in great shape, and I'm giving it a tune up and go through. I have intentions for it to be hanging around my shop until they put me in the dirt, it's just such a nice machine with a great versatile medium size. I was thinking about one day taking the headstock apart, giving it a thorough go through, checking bearings, etc. Pulling the spindle CORRECTLY was always the nerve racking part for me, so I'm so glad that you read my mind and made an awesome instructional video! 😄😄 Appreciate all the knowledge you imparted, and I hope there are more of us out there that will takes these old Monarchs and bring 'em back to life again. They were built so well and so robustly that I think, with the proper care and attention, they could have a lifespan of several centuries....if anyone cares enough in the future to make that happen. Thanks again Gary, just got another Sub!!!!
I do like monarch Lathes , got my first big monarch sometime around 1986. It was a 1940s vintage 22 inch swing at least 6 foot between centers. I sold that one years ago and always regretted it. I do not show much of my stuff on my channel, but I have been trying to save vintage equipment for many years. I appreciate you taking the time to check out the video. Gary
Apparently you know what you're doing! Thanks for taking us, me, don't know much about lathes, along for the adventure. Because this is the RU-vid content we're all looking for... generously sharing your knowledge.
I'm probably one who was whining about more, more, more! Thanks for this one; I felt like I was right there getting my hands greasy. :) I started thinking about the designers back in the day at Monarch... some guy with a white shirt and a little slide rule in his pocket working out the gearing for that thing; the gearbox just boggles my mind. And every part of that lathe needed some careful thought; there's cleverness all through it. And no CAD. I'm super impressed!
There were definitely some very smart people back in the day. I don’t think there’s very many machining tricks that haven’t been done by somebody many years ago. I appreciate you checking out the video and leaving a comment. Gary
Randy, the truth is that was footage done over a year ago. I wasn’t going to make a video showing it but after seeing Keith Fenner tearing into his monarch I thought I would show it. It has been in the shop for also over a year and I think I will show a more in-depth video of getting it into the shop. Always nice to have you stop by the channel. Also, I got tired just watching you guys stack all the hay in the barn. Lot of work. Gary
Ken, all that footage has been buried in my computer for over a year. Wasn’t sure how interested people would be watching it. I’m glad you enjoyed it. Thanks for checking out the video. Gary
@@OldIronMachineWorks Yes, I recognize the Monarch from your previous videos. I appreciate the detail that you show in the repair . A wonderful machine that deserves all the TLC that you give it .
Gday Gary, they made machines to last back in the day, everything is built heavy duty, everything looks in great condition inside the headstock and gearbox, I quite enjoy the longer in-depth videos, great job as always mate, Cheers
Matty, I really appreciate your kind words. Sorry I’m late responding to your comment, been slammed at work the last couple days and not much time for RU-vid. My day job is starting to interfere with my RU-vid, not sure what I’m gonna do about that LOL Always nice to have you stop by. Gary
Hi Gary. Been watching and following along with your Monarch restoration on my television, but can't comment there. Thought I better log on to the computer and provide some positive feedback 😊. Very nice work Gary and thanks for sharing. Regards, Aaron.
Thank you Aaron, I really appreciate it. I have recently been watching more RU-vid videos on my big screen but have the same dilemma when it comes to leaving a comment. I need to make reminders to myself on what channels to go back to and leave a comment. Always great to have you stop by. Gary
On my mill someone had dropped a locking ring into the gearbox in such a place that it would act as a one-way ratchet against a gear. Took me a while to figure out why the feed only worked in one direction, but at least nothing was broken.
you and Keith Fenner, removing spindles from your old Monarchs.....fantastic machines and videos......thanks for sharing with us mortals.......Paul in Florida
Gary, I do like watching all of it. There are things I didn’t know about these machines that I wouldn’t be seeing in a short version. People can always fast forward if they’re impatient.
Mel, I always try to edit my videos to the point where if somebody fast forwards it there’s a good chance they will miss something. So I still try to edit very heavily but leave certain things in that I feel are important. Always nice to have you stop by the channel. Gary
I love the old iron. It still works after all this time. That is the secret to why the old machine makers are out of business. They couldn't stay in bussiness trying to keep up with the cheap overseas imports.
I quite like the long format myself. I think it solves for both tastes because others can fast forward if they choose. I'm nowhere near your level, but one of the most important and most difficult shop tasks for me to learn was patience, when to walk away. I've noticed that most people whose mechanical aptitude I admire all seem to have the same easygoing nature. So I think there's also a lesson in watching you in the long-term format. Some of the more abridged videos give the impression one can just slam through this kind of work, I think the reality is that it takes a lot more being thoughtful and observant
Patience goes a long ways, generally speaking I have pretty good patience but on occasion I do need to walk away from something and come back to the job later. Yesterday I had a 14 hour day on a job that was giving me fits and at 10 PM I said enough, it will be waiting for me in the morning. Appreciate you watching the videos. Gary
Long or short, I'll watch whatever you care to share Gary. The Bridge has to be included of course. Loved the faster clip of it opening. I have to drive to LA from Seattle in October, maybe I'll swing by and watch the Bridge for awhile. 😀
Alan, Thank you. And the ship will be in most all my videos because it does have meaning to me. Someday I’ll do a video talking more about the bridge and the meaning I have with it. I am sure anytime you are around the bridge you won’t have to wait long for it to open. Seems like more and more ships are going through all the time. Appreciate you checking out the video. Gary
I love your explanations! You talk slowly and clearly. No annoying music. Just the way I want! You are a methodical and thoughtful person. Excellent video. Very instructive. Will now watch with the same joy and excitement part two!! Thank you for posting and sharing. We learn well from you! GOD Bless. WWG1WGA
Great work, you're so far above my pay grade I can barely see you up there! hehehe I learn a lot from watching your repairs. This is gonna be one amazing machine. I can't even compete with you on tonnage, it seems you'll easily win with the most iron of most people I know. That's a D1 mount on steroids...🙃 That taper bearing on the spindle looks very nice, I'm sure those aren't cheap to get in precision grade that Monarch used...you may have mentioned, but the one thing I have pondered with a job like this is how the preload is set on the spindle bearings?
According to Monarch, you just want to adjust them to where you have a little drag on the spindle. There’s really no reason to over tighten the bearings. I appreciate you taking the time to watch the video. Gary
Gary, put me in the longer video camp, be sure to include the any “ah shits” you run into and the work around. Most everybody else edits those out and I find it really helpful to see how others get around seemingly dead ends without leaving apprentice marks. Sorry I don’t live next store, I’d love to hold the camera when you need 3 hands.
I can not imagine any machinist not wiping the mating surfaces when changing a chuck. Good shout out to Max Grant's channel. Just like you he puts out exalant content but his channel remains small.
Andy, I guess over the years not much surprises me anymore. My belief when changing a chuck also requires blowing air to help get everything out. But the crap that was behind that Chuck was uncalled for. I really enjoy Max’s channel. I really enjoy watching people that do this for a living and Max is definitely one of them. Always appreciate it when you stop by the channel. And I don’t mind my channel Growing on a slower pace, I don’t want to get a fat head. LOL Gary
George, yes it is the Rio Vista Bridge. I’m glad you found the channel and I hope you enjoy some of my contacts. And don’t forget to subscribe LOL. Gary
I have a couple of D1-6 chucks that have been mounted not clean by someone way before me. Thankfully they are not too bad to be a disaster and they are four jaws so run out is not a huge deal. It's not hard to keep those surfaces clean, some people must be either wicked lazy or completely ignorant. Maybe both. Anyway what a nice lathe you have there.
Warren, anytime somebody tells me they have run out in there Chuck the first thing I say is take the chuck off, clean and stone areas and reinstall. Thanks for checking out the video. Gary
I'd just machine a cast iron plug for that hole and glue it with some loctite, so no water can run into the headstock. Apart from that, I see no disadvantage of having a hole in there.... Beautiful lathe btw, better, more useful size than those tiny 10EEs ;-D
The reason why I wanted a more substantial plug is to give me an area to mount a bracket to hold a DRO in the future. I also have a 10EE that is waiting for me to give it some love someday. But if I could only have one Lathe it would not be a 10 EE. Just not big enough for the stuff I do. Appreciate you checking out the video. Gary
what auction did you get that out of? I live in Sacramento county and have seen nice lathes on bidspotter, west auctions, and a few others. I just bought an old sebastian lathe for $300 and Im about to start working on it. I am just learning about how to run machine tools..
My monarch came out of a machine shop in Turlock. The particular Machine Shop bought it brand new in 1955 and it sat in the same building until I purchased it and brought it home. I have been playing around with machinery since the mid 70s. And all these years later I still enjoy it. Appreciate you checking out the video. Gary
JD, i’m forgetting the exact name right now but I have showed it in some of my videos. It’s just a rust inhibitor. But there are a lot of products as simple as WD-40 that make a huge difference to help keep the flash rust from happening. But the key is to spray it on before it totally dries. Gary
I bet you'll be extremely careful to not crash this lathe as hard as it must have been crashed...the Monarch speaks for itself in this case, the fact that only that little fork was broke...or do you think it was just someone jamming the knob hard enough to break it and the lathe ran fine??? This is an intimidating job for certain...pretty far above my intimidation level...but when I worked on my Rivett it was very logical just how this Monarch is put together...I've seen more than one person struggle getting the spindle set correctly, but Jeff Lehn (I think you follow him on IG) had a friend in TN that did manage to get them set correctly on a Rivett, and he had to buy new precision bearings to boot! Is that front spindle taper bearing a Timken? I guess this lathe meets the definition of being worked hard and put away wet...can't wait to see it after you get all these beautiful gears and spindle nose cleaned up...
Hey Doug, I got an American pacemaker I’ll let you take off my hands. Although it might be a little long drive for you. Don’t tell anybody but that footage was taken over a year ago. I just didn’t think it was worth a video. But I am getting a little more time to play around with it now that I can use it in machining the natural gas compressor valves. Hope you’re doing well. Gary
Ken, over the years I have seen many parts that I wondered how they got past quality control. I’m sure you have seen your fair share to. Always nice to have you stop by the channel. Now remember I’m the one in Rio Vista About 25 miles away. 😄 Gary
No, everything cleaned up great. They must’ve changed the chuck on a Friday and wanted to get the heck out of there LOL. Takes more than that to her to monarch :)
I get it that there always has to be a weak link in any system, and I understand they claim that they engineer it so the weak part always breaks to protect the rest of the system. However I would actually believe that more, if that one part that always broke - didnt require disassembly of half the machine... instead this tells me the engineering of the system was poor...
Jack, The main reason that the shifting fork brakes is due to operator trying to shift the speeds while the spindle is still turning. If the operator operated it correctly that part would not break. But with that being said, I for one wished that I did not have to pull the spindle to get to the shifting fort. I have always said if there’s something that man has made there’s always room for improvement. I appreciate you taking the time to check out the video. Gary
