Maximat Standard

Was a bit curious this morning, so I unscrewed the plastic holding ring.

I thought a decent image of the back side of the holding ring would be informative, as it has the integrated shaft keys.

Yes, very informative picture. It explains why the "Key" had no leader/part number.
I certainly don't understand their section view depiction, but your picture answers the question.

One last pic of Maximat internal parts.


I purchased a set of face pin spanner wrenches to get access to the bearings. The outer ring came loose easily, but the construction doesn't allow enough space to get the pin wrench on the inner ring. A different wrench or some custom ring with pins will be required to get it apart.

Sadly, a problem for the new owner. My wife and I decided to downsize, and I just don't have the time (or machine hauling capability) to play with and then transport the latest toy. Aside from one dry set of bearings on the milling head, both motors have dry bearings and might need some repairs. A friend in town needed a bigger hobby lathe and is willing to work on it, so it's off to a new home.

Hi all
Regarding the serial number. I have a similar lathe with serial C 66 12 17 - looks like date format YY MM DD - but haven't found anything about the format of the serial numbers. Don't know the model though.
Need to get it in its final position so I can finish the restoration.

Welcome to H-M, @Questjon
Very nice looking machine. Did you just acquire it?

Thanks. I got it about a year ago. I do know most of the history of this lathe though. My father started a electrical engineer company around 1965. The company bought the lathe around that time. Since it was mostly an electronic firm the lathe got very little use. In 2008 the firm joined another bigger engineering firm and the lathe was put in storage. There it sat until 2022 when they wanted to close the storage facility. I contacted the facility manager and asked to buy the lathe - well he said I could just take it for free if I removed it right away. Which I did.

That's a great story. You're keeping it in the family.

Hello folks it so good to see someone else with this issue that has a fix . I know as much about this craft as I do building reusable rockets that run on moon dust and carrot juice. In my travels I came across this [vintage wonderful mess of mechanical art] in the garage of an 85 yr old wonderful man that was full of stories. I could not leave this sitting in the once busy shop of yesterday... it must be rescued before some kid sold it for scrap.
Moving was a task for much younger men , I did it by hand with one freind and what could have been the equivalent of Egyptian stone moving methods. Luckily we both have all our fingers.
Many accessories came with this tool and the sheetmetal break shear roller combo that I too picked up for home.
I've played on and off over 2 years, giving up for more important and pressing projects when the gears thing kept me at dead ends. I've spent 100 plus buying gears that don't work ( sizes being incorrect or information being wrong. ) I was about to take the broken cogs to a machine shop to get the proper gear size. The mods, pitches, etc was too much for my small brain to over come with tools at hand.
With all that being said( hoping to bring a smile) with my failures i hope you can say by looking at my photos that the likes or correct for my needs.
It appears the 2 gears on your lever that run side by side are both steel? And you have one nylon gear. We'll as you see i have 2 nylons. Maybe because God loves me but wants to test me. If your file is right for my needs. Ill be half way there.
Thank you for any help.
This machine maybe to needy for me knowledge to make here 100% but i do want to make her usable if not to find a good home and buy something easier to get on with. As I mentioned this is all over my head.
oh yes. I am also missing the adjustment stop the lock uses but I think I can make this part unless someone has an extra. Lol not many extras in this hobbybwith this machine cheers Joe

Below is a link to a Gear Dimension Calculator which may help you define the damaged gears.
Enter the known number of teeth and edit the other values until the calculated OD matches (closely) what you measure on the damaged gears.

Calculator to make the right dimensions for a gear or gear blank: calculate gear pitch, outer diameter (OD), root diameter, and clearance.

Nice find.

Replacement gears are now easily made on a 3D printer. If you don't have a friend with one check your local makerspace or community college.

I really didn't need another lathe, but I saw an Emco Maximat for sale with a stand, a 3 jaw chuck, a small vise, faceplate and various other parts for a very good price, so I couldn't pass it up. A very nice fellow up in Newark, Delaware even helped load it on my trailer.

I have not yet checked out the motors, but I noticed the mill/drill head appears to have dry grease in it. Has anyone pulled one of these apart? The drive pulley end has some sort of spring pin, and it looks like the rest of it comes apart from the chuck end, as there's two rings with pin holes for disassembly. Any trick to getting out the spring pin out of the pulley end?

The manual indicates use of Esso Nebula EP No. 1 grease. Can anyone provide advice as to a source for this grease or a suitable substitute?

The bed has a serial number of 651014. Any idea of how old this machine might be? I have not found anything other than "Maximat Standard" on the machine itself, but some literature that came with the manual indicates it may be a model MQ-3100.

Here's some pics and info.

I appreciate any guidance/advice that might be offered.

Hello TomKro

I have just a Maximat Compact with the serial number 651074, and I´m looking for a Manual and Spare Parts Manual for the machine.
Do you have èlectronically manuals?
