Oh thanks his name is actually Kolby- he doesn’t say it very clearly so it sometimes sounds like Cole, Kobe, etc. Thanks for watching!

[@DCT_Aaron_Engineering]

Sorry to hear that you had trouble with your Monarch lathe. So glad you get her up and running again, you would happy now. It was great to see your young bloke make a video appearance also. Hope you and your family had a great Christmas. Cheers, Aaron.

[@robertoswalt319]

When you said that a nut had fallen down I was happy to see that nothing had fouled gears and had broken some teeth. Great video and good to meet your son, he looks like a fine young man and I know you are proud of him.

[@tomeyssen9674]

Glad nothing got hurt....beautiful lathe and work. Amazing having a lathe so well built one has to almost have a lift just to remove the top cover...😊. I'm just glad the nut didnt get into those gears...whew! Anyway, thanks for your videos. -T

[@AlwaysSunnyintheShop]

It really is incredible how well made this machine is!

[@tiredoldmechanic1791]

I'm glad you realized that the lock wasn't keyed to the shaft. I noticed there wasn't a tang in the center of that lock but I didn't know if the shaft had a keyway. Those locks can be used against a part that is keyed or splined to a shaft so one tab is bent toward a notch in the part and another into the nut. Sometimes those cone shaped locks get caught in the nut or the socket as it is tightened down and it breaks that inner tang. You could use Loctite on it too. There wasn't such a thing when that lathe was built.

[@Gottenhimfella]

I would certainly be inclined to use Loctite on that "set screw" (in other jurisdictions they're called grub screws) on the shift fork which had loosened off.

[@jerrytalley337]

We had Monarch lathe just like yours at the school bus garage I supervised. Painted it the same color too. Bought it from state surplus. Ours didn't have the power compound feed though. You have a real gem. A very accurate lathe. The only thing I considered a draw back was that it would have been nice if Moharch had made the machine with a 2 inch spindle bore. 1 3/8 inch is sometimes too small for longer shaft work. Don't get me wrong, I loved the lathe. Also, just a note, the nut and washer combination you were working with are made so that no matter where the nut stops when tight, one of the tangs on the washer will line up with a groove in the nut for locking. Great videos.

[@sharkrivermachine]

Glad that it was a relatively simple fix, Happy New Year

[@madscientist5969]

Happy New Year...I'm glad it was a simple and easy fix.

[@MartsGarage]

I was impressed that the part was an off the shelf item! I hope this one lasts ok. That is a beautiful machine. It makes the modern boxy looking jobs look ugly by comparison.

[@AlwaysSunnyintheShop]

Yeah this uses a common bearing nut and washer assembly. Any bearing supply will have them, though this one is quite small compared to the normal sizes in use. Very nice that I found one with one phone call though.

[@MCEngineeringInc]

Good to hear the bronze shoes are holding up well in that application. Also, good that there was no damage. 👍🏻

[@OldtimeIronman]

Thats a beautiful machine, you'll be OK. Thats one place where I would use loctite for sure. The trick with those tabs is to use a hammer and punch to flatten the tab right into the slot. Glad you got it.

[@georgeswindoll9138]

Glad to see you are using a mechanical lift to remove that cover, I have suffered back injury myself, you have to always be careful!!!

[@mikecabe6127]

Glad it was an easy fix.......Happy New Year!!!!!

[@GaryGrumble]

When you were first tightening THE nut I saw the keeper washer turn. Did the fingers of your clever socket snag the washer and sheer the keyed piece off the inside of the washer? If so you may have sheered it off again this time. You could probably check this by removing the small back inspection port.

[@AlwaysSunnyintheShop]

I bent the tab over after everything was tightened up, so that shouldn't be an issue.

[@Donkusdelux]

Machine down time is never fun, I have had to take a machine apart and put it back together 3 times before to fix a problem. Patience is a must to fully understand the problem. That is such a clean lathe... she is not even broke in yet.

[@RobB_VK6ES]

I can see why those Monarchs are so liked, one tough looking lathe. Never seen one here in Aus. The nut you made looks to have too much bevel so the tag washer will only slightly engage. Nice restoration too, I'm the same colour as the lathe :)

[@AlwaysSunnyintheShop]

I misspoke in the video- I made the tool to remove the nut, not the nut itself. It was made by SKF so it has been engineered correctly. The tang was broken on the washer when I reassembled things months ago, so it never had a chance of working. Should be good for a long while going forward.

[@dcobel60]

Aaron, as I am also rebuilding my 60 series, which is similar to yours, I came across an entry in the Monarch Service Manual that recommends 9 inch lbs torque on that end nut once you set the adjustment for the clutch, then bending 2 tabs into the nut locking way, in this manner the washer flat is unable to move and transfer torque to the washer allowing it to shear off the key way stop tab, in other words, the reason the tab sheared off was the nut was not tight enough. (Guess how I found this out, (( twice)) In all the videos out in U-Tube land, I have yet to see any videos or repair videos of Monarch lathe head-stocks, ( I suppose its because they do not break down ) other than yours, Keith Rucker, and Adam Booth but only for minor issues such as your broken washer,...I do have an issue that you may be able to answer,....does your main clutch bearing leak behind the clutch plate once grease has been pumped into the zert's fitting ? Great looking kid ! Merry Christmas, and a Happy new year !

[@Keechization]

gland nuts need torque, even if adjusting lash on a shaft!

[@ramaroodle]

Gotta be the cleanest machine I've ever seen! Nice work.

[@markmuranyi9289]

Aaron. I have used a flexible tipped magnet to fish around the bottom of the head stock. 99 percent of the time has proven it's worth. Just throwing it out there.

[@markmuranyi9289]

On edit. Even though you did retrieve the nut I see that you had to remove that end housing to use your custom nut driver. I was thinking that you did not have to remove that outer housing. Great job.

[@AlwaysSunnyintheShop]

Yeah a magnet is helpful, but my hands were getting messy either way, so might as well keep an extra tool out of the occasion. And yes, that cover had to come off no matter what. Thanks for watching!

[@denniswilliams8747]

Consider adding a drilled and tapped hole at the balance point in that 150 pound top cove. Screw in an eye so the shop crake could pick it. Thanks

[@1970chevelle396]

You got Lucky.

[@bcbloc02]

Typically those style locks I see are used with 2 nuts, is there space for 2 on the shaft so you can jam them together?

[@AlwaysSunnyintheShop]

There might be room. The book only shows one, and a buddy with a Series 60 only had one on his- wonder if it’d be worth the insurance even if Monarch didn’t design it that way.

[@metalworksmachineshop]

As soon as you sat the washer down i didnt see the internal or external key on it. Very nice machine,

[@BronzeAgePuritan]

I sympathize about the oil getting everywhere, so many rags get used. I stopped using the blue ones as I saw them leave behind so many fibers- they seem to disintegrate. I have gone to just using old tshirts and throwing them in the wash periodically. Also, I work where there are leveling machines for sheet steel. Whenever we rebuild the heads we're left with a bucket bearings like this one you dealt with, washers too, all new parts go back in just to be sure. Seeing your washer with the broken tab demonstrates why.

[@1889michaelcraig]

Idk what it is with that color but to me it screams Monarch. Beautiful Lathe Sir!

[@Panzax1]

That headstock cover needs a tapped hole in the middle for an eye bolt. If you put some sealant on the cover before you reassemble it it will be a lot less oily all around. I am sure there was a gasket there from the factory.

[@RockingJOffroad]

It’s always good when the replacement part costs $1.16! Even if it is a pain to get to the bad part!

[@etheroar6312]

Probably could have gotten a NOS washer for less than $100.00. But not much less.

[@markgrevatt4867]

Glad it was a simple fix. And there was no damage to that beautiful monarch lathe. I too suffer with back pain on a daily basis Hope your not suffering with it Don't know if this would be any help to you. But thought I mention it anyway. . If your gini lift goes up higher than the headstock cover plate Could you not make two types of hooks where the cap screws on the headstock cover goes. And a couple of straps. So your not having to struggle with all the weight on your back. Leaning over. May or might not help you. But I would certainly add something to the gini lift to make life easier lifting the cover off. Just a thought. Happy new year to you & your family. Still a beautiful lathe.

[@AlwaysSunnyintheShop]

It’s at the maximum height as you see it in the video. It would be nice if it went up higher- it has forks under the platform plate, so it would be handy if it reached up higher.

[@markgrevatt4867]

@@AlwaysSunnyintheShop how about fixing two metal angle plates to the side of the gini. At the top of both sides. That way you could attach a plate. And Bob's your uncle no need to struggle anymore. With all the weight. I'm sure you could figure something out. Be a cool little project. And then you could attach a one of those off on magnetic clamps quit cheap on ebay.

[@markgrevatt4867]

Just thinking of your back buddy. I had a severe injury 20 odd years ago. 18 operations later and I still suffer on a daily basis. Hope you can figure something out. That lid looks extremely heavy. And certainly wouldn't want that dropping of the floor. Being cast iron. Hope your recovering nicely with your back surgery. Other than that that's a beautiful lathe you have there. And extremely quite too. I haven't even started my lathe restoration but looking forward to it. But mines a Harrison L13. But there known for being noisy.

[@JamesDedmon]

Your correct it’s always the little parts that fail

[@scottlundy257]

How about using a modern nylon lock nut with the fold over lock ?

[@AlwaysSunnyintheShop]

I didn’t see anything in this thread size other than the bearing locknut style.

[@ALSomthin]

Well hope some of the comments may have the answer for you on other issues you may have in the future. Knowing that having manuals though is essential from my years of being an industrial mechanic fixing production machining centers. I recommend you get a good set for your lathe if you dont already have a set. Paint still looks good though!!

[@crockteerden4023]

Did you have the lock washer tab bent to lock the nut in place?

[@AlwaysSunnyintheShop]

I did- showed it in the video using the brass punch and hammer.

[@larrysmurthwaite773]

Man oh man, not knowing what is causing the issue, been there but I wasn’t so lucky, mine had a bearing issue. That lathe is so big that washer must be the single least expensive part on it? So happy for you to have it be not expensive, time consuming none the less. Cool to see your mini me.

[@AlwaysSunnyintheShop]

I think the only cheaper part on the lathe might be one of the screws!

[@melgross]

The concept of those washer/nut combinations is that normally, the nut will vibrate off, by itself. The washer supposedly digs int,, and prevents that, but not as much as hoped for. By locking tabs into the nut, it integrates the washer and nut, making it much more difficult for either to loosen. Hopefully, there is a groove for an internal washer tab to be bend into, but not always. And yes,, the tapered sides need to be together. A,so, while I had that top off, I would have installed a lift ring. My foldable lift is invaluable.

[@AlwaysSunnyintheShop]

A lift is certainly needed in my shop, but space is limited. Hopefully we can get the place expanded and have plenty of room for a gantry crane.

[@melgross]

AlwaysSunnyintheShop when folded, it only takes up about 15”x18”.

[@erikjohansson1814]

See it from the bright side, you have new video content people enjoy to watch 😄

[@mikemarler8224]

So. besides working on the other tools in the shop, what are you using the lathe for?

[@AlwaysSunnyintheShop]

Whatever comes into the shop. I don’t advertise for work, but word of mouth sends some stuff to me. It’s still just a hobby at this point so even if doesn’t get used much that’s ok.

[@mikemarler8224]

@@AlwaysSunnyintheShop So what kind of jobs have been coming into your shop?

[@royalfolkspark]

You need an overhead lifting system. More repairs down the road.

[@BillKnu]

I have experiences loading heavy and/or items into the confined spaces of CNC lathes. Forklifts were almost to impossible to use. Overhead cranes work well. In a basement or low overhead you sight consider an overhead door track with a trolly and a block and tackle fastened to joists.

[@P888JAC]

Trying to help here from Scotland ! Looking so far away but if the tab of the lock washer is sheared it means there is a rotary load on it. After you put everything together I saw movement on the clutch at the left of the video the engagement cone should ride up the taper and rest at the biggest diameter, from the picture it stops on taper if this is so then there is constant pressure on the shaft pulling on the clutch and loading the nut and as the only thing stopping the nut from turning is the washer all rotating load is on the tab of said washer which is very thin for such a large load and will shear. Check that the clutch rollers are resting on the large diameter of the engagement cone, this means there is no load on shaft. Or you will have the same thing happening again. Hope I’ve explained things easily

[@AlwaysSunnyintheShop]

I think I understand what you’re saying- the rollers go up a cone and into a shallow groove. That’s where I adjusted it to sit and in operation it’s nice and smooth. Thanks!

[@josephcalvosa8272]

Loctite, nyloc, and lacing wire, these are a few of my favorite things.😎

[@jakezgab8576]

Can u get a close up on the end of that shaft

[@stuarth43]

do you have a rotary converter

[@AlwaysSunnyintheShop]

No I’d like to get an outdoor model to power the whole shop. The Monarch is powered by a Fuji Electric VFD.

[@SkylersRants]

It’s hard to tell from the video, but perhaps a second set screw to jam the first one in place might help.

[@donjohnston9554]

Arron, new to your channel, great content. Darn nice lathe, ADAM GET PAINTING and POLISHING. LOL. Joseph below has it right, safety nut wire, loctite or double lock nut would be my peace of mind solution, seeing as there is only 9 in lbs torque. If the keyed tab washer broke once, umm? Your call for sure. looking forward to more vids and seeing how the combo feed would work. 😁👌

[@AlwaysSunnyintheShop]

Hi Don, thanks for checking out the channel! Yeah I will check on it after an hour or two of run time, and if it has moved even a little, we’ll clean everything really well and Loctite it in place.

[@aaronroberts3848]

I'm picking up the same exit lathe tomorrow. I'm going to be opening it up as well as there is no feeds engaging what so ever . All levers were set to the right position so something let loose in it. I do have a 60 series manual on the way but if anyone has been in this section on the 60-61 series please let me know .

[@AlwaysSunnyintheShop]

Yikes I’m not sure what would cause that. Check to make sure the Thread/Feed lever to make sure it’s not in neutral, and the same with the lead screw reverse lever on the headstock under the speed selector levers- if it’s in neutral neither the feed nor threading rod will be rotating.

[@aaronroberts3848]

@@AlwaysSunnyintheShop it is the tool room model and has the lead screw reverse lever on the carriage. I just got it home yesterday so I will go through it . Its my understanding it wasn't used bc the feeds stopped working. Hopefully I can see how it is driven in the manual I have coming . I'm hoping its just a shear pin or something but probably not. I got the lathe for free so I'm already ahead !

[@AlwaysSunnyintheShop]

@@aaronroberts3848 Yeah check inside the headstock- the nearest shaft to the operator does have a shear pin in it IIRC, and it could be as dumb as the quadrant needing to be adjusted and no one ever took off the cover to look. If that's out of position, no feeds or threading. Free is a great place to start!

[@fpoastro]

It looked like your lock washer was spinning freely on the shaft which if it is that no workie.

[@AlwaysSunnyintheShop]

Yeah I saw that when editing the video- pretty obvious when I saw that.

[@OmegaSparky]

I went back and looked at the original video when he installed the new shoes and though there wasn't a clear shot of the washer, it didn't look like there was an inner tooth to catch in the keyway.

[@Robert-ko6wr]

Forced? Any day in the shop is a great day! Who said that? Why you said that. Enjoy watching your videos. Happy New Year!

[@MrJimhayes1]

I’m pretty sure you’re working on the brake con area I think that item should be tightened up against the shoulder then the tab bent over if they were merit where marks on the clutch again you need to readjust the clutch if there were some grooves in that area you were referring to they were just from age of the brake disc wearing good luck

[@jhbonarius]

[@coconutpie333]

dont know if it matters but aboms monarch shifting fork is backwards to yours -the oil trough is on the left

[@BillKnu]

Why do you not have some overhead lifting device? A barn over barn door track and a block and tackle. A hydraulick engine hoist. You will in some time finding yourself want to turn something heavy or difficult to handle to chuck.

[@AlwaysSunnyintheShop]

I wish I did but space is a lot tighter in here than people realize. I frequently have to ask for help from my neighbor for lifting heavy things that a hoist would be able to do for me.

[@P888JAC]

Adding an afterthought, there would be initial load on shaft initially so there may have been a thrust bearing before the nut? Just thinking through stuff Regarding set screw being loose the bronze shoe will rotate in the actuator causing wear on the pivot maybe there should be a grove that the dog point grub screw can rotate? A thought

[@AlwaysSunnyintheShop]

The parts diagram from Monarch doesn’t show any other parts to this assembly. Might have been better designed with a backup of some kind.

[@smithparkins4862]

Hi Aaron, Some help for moving that top cast lid. Look inside the bolt holes used to fasten the lid to the headstock, there may be some threads for using larger bolts to attach rigging for lifting of the lid. Usually, the builders had such things. Worth a look . Hopefully you don't ever have to back in there again, but if you do, check it out. I am thinking you can use the Genie lift and some chain. I think you mentioned going in later to put sealant on. Have a look then... Instaschmit.......

Lock washers need to be locked both sides unless they are keyed, ie have a tab in the centre hole that fits in a keyed slot.

does it have a magnetic clutch?

I don't think you should put the nut back on till cleaning the nut and screw with acetone and put the lowest force locktight on the threads. But only around where the nut seats not the full shaft.

[@RubenKelevra]

3:12 seriously? Add two bolts with a hook attach them with a nut, and lift it with a manual chain hoist. It's cheap and you don't overload your back 😙🎶

Good idea- another viewer went back to my install of these components earlier last year and saw that the washer was already broken. At that time I had the headstock clean enough to eat out of, so the broken tab made its way out at that time.
