Monarch 10EE Restoration 1: Removing the Bed of the Lathe for Grinding 

Cool. I have been looking forward to the 10ee project! "Dont get too excited"... to late for that.

Hello Keith, I have a shop tip for you, that i have used in my shop for years. When you are doing a tear down of any kind. Get a box of quart zip lock bags for the shop. As you tear something down, Use the bags to store the bolts and label them from where they came from. This way during reassembly you will have a reference to where they came from. Enjoy your channel.

That potentiometer deserves it's own video !!

I’ve never clicked on one of your videos so fast!! I’m looking forward to this rebuild series

Looking forward to seeing the Horizontal Boring Mill restoration project. As always, so many projects & so little time.

I really enjoyed having Lance join you for this episode; the two of you make a good team. Please do more collaborations with him.

Can't wait to see this go back together!

Lance will be the traveling lathe guru.

Great editing Keith, love this series!

25:23 I kept waiting for that apron to fall! 😂

I love the art deco shape.

The two of you were having so much fun together!

This was the lathe that I ran when I served my apprenticeship back in the '70s. I have represented a machine tool distributor that represented Monarch as a sales guy. I saw proposals to reman and update the electrics by Monarch in the $65K range. When I ran them their electronic drive used vacuum tubes about 12" in height, of course, that's all gone now. These are the Rolls Royces of machine tools. As smooth as silk and absolutely dead accurate. A guy couldn't blame his machine.

A beautiful machine of solid design from yesteryear.....exciting project....thanx for sharing....

FINALLY!!! We’ve been waiting for years for you to begin this restomod!!!

Boy, this was one of the most interesting videos I have ever watched! I can't wait to see this lathe being restored, I just love the old machinery and how well it was made compared to modern stuff.

Soo happy to see this started! It will take some time, gotta wait in line of course but at least its now in the line.

Awesome. A pleasure to watch

I just finished my model A monarch, looking forward to the restoration on yours. Very interesting. Great video Keith, keep'um coming.

It’s nice to see you and Lance working together. Collaboration is awesome!

I'm not sure why, but that was an absolute joy to watch.

Lance very nice of you to help all the folks you help a good man. Keith looking forward to the series.

Super excited about your 10EE restoration!

The specs will be hard,.0005" over all on the bed grind, .0003" concave on a 5" face cut, and more, I did post the blue publication factory specs on the fake machinist forum. The best craftsmen in the world built, and still build these. Wow, what a challenge!

Been running my 10EE since 1988 so I'll be paying close attention to all videos on this one...thanks!

Love the restoration videos Keith!

Thanks Keith.

Thank you for sharing. Enjoyed.

Eagerly awaiting this series. Thanks for sharing.

Tell Lance he needs his own channel.

Lance is a great guy.. Very helpfull !

I do find it entertaining, the way you chaps pronounce "monarch" - like Monn-ark, where we in England (which actually has a monarch) say it more like Monn-uck. For what it's worth, I'm no fan of the monarchy in Britain or in principle, but I would love to understand why this word is pronounced so differently on different sides of the Atlantic ocean. Fascinating video as always!

Hilarious! Both maneuvering to be the one to do the most! Lucky no elbows or foul shots taken. Such great sportsmanship and cooperation.

Great way to start the week. I love watching other people work. Coffee and a couple of clicks, voila, a great video. Thanks, it's appreciated.

Nice to see you get to the 10EE! Looking forward to the eventual restoration.

These are some blockbuster restorations you've got on the go!

Great video Keith, Always love hanging out with you!!! I got to learn some of the differences between the round and square dials. Safe travels, I know you will have blast up there!!!

to professional Machinist saving American history thank you

Awe Keith you don't like living dangerously? LOL. With collecting antique tractors I've got one that got stalled in restoration since 1993. Life got in the way as did health, fire, death, etc. It's all straight forward to go back together again though.

looking forward to this one Keith. The Planer and this lathe are my kind of interest. Thanks for sharing with us. Hope you take us thru the grinding shop and the grinding process.

Can’t wait to see this one Keith. I was hoping you would do a real before and after (grinding/scraping) comparison of some key measurements but I know that’s not always possible - especially when it’s not a functioning machine.

I didn't think there was any sheet metal anywhere on that Monarch but there it was, right on top of the headstock holding the oil fil screen.

So glad you decided to restore that lathe! Felt so sad when you said you may not after getting the other lathe.

Game plans are Good. GOOD LUCK

I have no idea why but. like many others I have really been looking forward to seeing this beauty brought back to life.

Please provide more information on the DC drive in your plan. Great video... long awaited.

EE is my favorite lathe I’ll be following this project

It is really going to be a great series of vid's seeing this 80 year old machine come back to life and make chips once again.

If Mr Rucker ever wanna get rid of it, it’s mine. I call dibs. 😁

I need friends like yours Keith. Everytime I have a project all my friends seem to be on vacation or call me with a cough and fever coming??? Lucky You!!!

Very cool a lot FUN

I'd enjoy a video of remaking that lead hammer. It's a simple project but sometimes that still makes a good video.

Of all the machines these guys have a 10ee is the only one I covet. Will be a great series.

just to let you know in advance. Monarch used two different electronic drives on the double E. If it has tubes in the drive there is little chance of repairing it. The other was solid state, and at least you can still buy some of the parts, but nothing from Monarch! I learned the hard way on this. Ended up replacing it with a Euro Drive, but was low on power. Last I heard the only tubes you can get are out of Russia.

Nice!! The floor does get further away the older you get... :-)

Gtta love "Blind Man's Bluff" when taking apart, or reassembly of something.

Managing parts - always my biggest challenge when something takes a day or two. Years? Wow! 90 minutes of work in a 36 minute video. Practically real time. Thanks for the video.

I really, really, hope Keith can follow through with the goal of making this one near perfect! He's so pressured under normal conditions, he tends to work toward "good enough", and that's a legit approach. For this one... it deserves extra special precision attention! :). Looking forward to it, when it bubbles up on the to-do list.

Hello Keith, boy this couldn’t have come at a better time. I just took delivery of my first lathe and yes it is a 10ee.

A friend of mine has one of these, and I've used it several times, particularly for making model fasteners, because he had a 5C collet chuck for it, along with a nearly full set of hex collets. It just made it all so much easier. It does require a mindset change, though, because the dials are direct-reading, unlike a normal machine lathe.

Nice job, nice machine, nice cooperation! Thank you Keith! (I would number the shims under the bed and check if other ones are attached to the top. Maybe critical to end up with a true turning lathe again) Best, Job

I have a 1943 10ee too, it came with a car transmission as a replacement for the motor/generator if you can believe it but I switched it over to a VFD. Will be cool to see the same machine completely restored.

Hiya Keith

I will be following this rebuild pretty closely. I have a 10EE in great shape, 3, 4, and collet chucks. I am trying to get a floor poured in my new shop building so I can set and level my lathes. All $300 purchases needing rebuilt. I also picked up a K.O. Lee grinder to rebuild. At least a decade worth of work, lol. I really enjoy watching and rewatching your videos and can't wait to get mine out there. I will be binge watching for a while!!

I had a little bit of time working with a great man that is grinding bed ways for over 30 years and he told me that they were actually grinding the bed ways convex, so the middle was 3-5 microns taller than the ends to compensate the weight of the carrige. This was in the early 70s and it was controlled by an NC computer.

I love the art deco design and pieces of these lathes. I know someone that has one just sitting around.

My 10EE was built in 1961, it is quite different. When I got it someone had removed the electronics module (Thyratrons and drivers) and replaced it with a very lark Variac. It had terrible speed regulation. I designed a solid state speed controller for it and it has been working great for the last 23 years. Your compound looks perfect, usually the left corner has been chewed off a bit.

Ahhhh… the day I have been waiting for. Good plan of attack. Hope the next episode is than later. Good luck

I'm brand new to Machining and was just given a monarch EE. I'm looking forward to watching you restore it. My first impressions of my lathe is that they are an electrical nightmare LOL. I have the square dial version.

I’m glad I picked my 10EE when I did. 1939 Sundstrand, however the original pump was replaced probably in the 70’s or 80’s. The original Westinghouse 3 hp motor was still in it & functional when I replaced it with a 5hp single phase. I didn’t want to be that guy who killed the 82 year old motor. You video is urging me to get back into the garage, I want to strip & repaint it.

Great instructional video. I cut my teeth in 1956 on a 1936 16 x 48 Monarch and know what quality machines they built then and now. I hope you made lots of digital photos to help during reassembly.

Hi Keith, I pulled the mg set on mine and made a rectifier bridge and feed it with a 300volt variac . less than 100bucs and it works beautiful

KEITH AND LANCE, GREAT JOB, GREAT VIDEO, I CAN'T WAIT FOR YOU TO GET STARTED ON THIS PROJECT, PET THE CATS AND DOGS FOR ME... SEE YOU ALL NEXT TIME...

Thanks Keith! I have been waiting for this day. I’ve got a 10ee that I’m restoring. It’s a process for the home gamer anyway, so we can all just follow along and know that you’re going to do it right and bring this great old machine back to better than new.

A comment on the drive: There are two basic kinds of DC electric motors: series and shunt. Series motors have enormous starting torque and the speed is controlled by the load. Automobile starting motors are of this type. You note a high speed sound of the starting motor when it does not engage it’s load properly. Electric fork lifts use this type of motor. Series motors use the load to control the speed. Vacuum cleaner motors are of this type and although they are AC they need to be attached to their fan to control the speed. The other type, shunt motors also have high starting torque but they control their own speed and do not need a load to prevent run away. Armatures have very little resistance, a locked rotor will quickly pop the breaker. But these motors also are generators. As the armature turns it generates a voltage opposite to the applied armature voltage and at some speed the voltages will balance and speed increase will stop. This idea is sometimes referred to as “back EMF” and misunderstood as a bad thing. When the motor slows because of a load then the voltage being generated is reduced and the motor will draw more current to carry the increased load. I know that the Monarch 10EE Motor has a series field in addition to the shunt field but the effect of this series field is secondary to the basic operation.

Love these restore videos. Let's get dirty!!

Run across your channel couple weeks ago. I really enjoy it some neat stuff and have learned alot about miling. Very interesting wish would've got into it years ago a small lathe would be so Handy. Might get one someday 🔧🔧

Keith - make sure the grinder indicates on the ball bearing gib ways front and back as these have to be parallel to the bed ways. It might make sense to clean up the feet where they contact the base at the same time to get rid of the wae time shims. Have to scrape in the 2 if you do that.

The whole time I was going...does it really need to be ground? But kudos to Keith..."it's the way I want to go with the project". You do you Keith, no regrets! Can't wait to watch the series.

Thanks for this entertaining video. On those machinist meetings there are competitions, how to center things in a 4 jaw the fastest. Maybe there could be competitions about how to strip a lathe? How to assemble it....

love lathe restoration monarch

Hopefully, as the lathe is reassembled, you will give us a good explanation of what the various parts do.

Fun to watch. But now we have to wait again. lol. I wish I could get to ArnFest this year. Hopefully next year.

This made me remember my grandpa when you said "i need a big wrench" "what size?" my Grandpa's line would been "Ohhh about a 10 pounder" lol

Glad the gearbox turned out to be fine! Didn’t sound promising when you initially got some water out!

15:34 Lance: "I'll have all this knowledge I don't need." Is there anyone among us who has not done something for the first time and learned how, just to never do that again? All of us become chock full of useless knowledge (and other materials, of course) yet we keeping acquiring more of it. I would wonder why but I know it's just a symptom of our sickness. I wouldn't have it any other way.

I would love to see your show and how repair for old lathe. I should have this at home.

I think Lance was refering to KB electronics. I love my KB vfd. Cheers

Good call to get help from Lance I am sure you will do the same for him.

I foresee Lance coming back to help with the scraping of the bed.

MUCH EXCITE!

Good morning from SE Louisiana 20 Sep 21.

I feel there'll be some "scraping" involved 😉😉😉😉👍👌

One of the best lathes ever made! Ole you got to do is, change the ole.😅

it would be nice to introduce your friend (and channel) in the information below the clip or in the info in the up right corner.

Confirmed: Blue T-Shirt and Khaki shorts are mandatory attire required for this sort of work.

I used to want a 10EE untill I saw this video... Now I Really want one

I was hoping for a quick peek inside the gearbox but I guess I’ll have to wait a while.

Keith, if you can show the bed grinding process, that would be awesome!

Worth commenting on, didn't hit "mother may I"
