A gentleman contacted us from Canada about this green Nardini TT-1230 E Turn-Tru metal lathe. He just got it, and was needing some wiring diagrams. We had just the manual he needed for the Nardini TT-1230E with the wiring and parts diagrams. More information on it is below. The Nardini TT-1230 E has a 12″ swing with an 8″ swing over the cross slide. The spindle bore 1 3/8″ with a D1-3 Camlock spindle nose. Maximum spindle speed is 2,000 RPMs. The tailstock has a #3 MT. In 1986 the Nardini TT-1230E sold for $4,795, which is the equivalent to $10,493.13 today.
Here’s a video of a similar machine:

One of our readers sent us these pictures of what turned out to be an older Rockwell-Delta-Milwaukee heavy duty wood shaper model 43-205 with serial number 78-2093. They were asking us to identify it so he could purchase the correct owner’s manual for it. This shaper is in good condition for it’s age. The serial number dates it to 1949. This was the biggest and heaviest wood shaper that Rockwell-Delta-Milwaukee ever made, and it was modeled after their popular unisaw design.
This shaper model came out in the Delta catalog in 1940 as the model 1340. The wood shaper has a 27″ x 28″ table with the standard 3/4″ spindle. It accepts a total of six interchangeable spindles: 5/16″, 1/2″, 3/4″ and 1″ standard spindles, 1/2″ stub spindle and a 3/4″ extra long spindle. This shaper was advertised as having a wide range of shaper cutter sizes.

Found this at the Missouri History Museum in St. Louis. This poster was illustrated by Pat Holbrooke in 1944. It was in the section displaying the war effort and actions taken in St. Louis and Missouri during the time. I have a lot of respect for the veterans of WWII. My father is even a Vietnam veteran.

While doing some research on this poster I found that Allposters.com is selling 18″ x 24″ and 24″ x 32″ versions of this poster
We’ve added 19 new Cincinnati milling machine and tool grinder operator’s instruction, service, and parts manuals.
We’ve been busy in our shop, but we’ve found some time to scan in and clean up over 1,400 pages of Cincinnati milling machine and tool grinder manuals for you. They have been uploaded and are now available in the Cincinnati section.
Cincinnati Milling Machine Co. 1926 Catalog Free PDF Download
Also we have a new Cincinnati Milling Machine Co. catalog that is now available in our Free PDF Catalogs download section. This Cincinnati catalog is 137 pages, and was printed in 1926. This is the oldest most comprehensive catalogs we’ve seen from the Cincinnati Milling Machine Co. A lot of care had to be taken into scanning this old catalog. Check it out, because we believe it was well worth it. It shows pictures of the old factory and laboratory facilities. It has all kinds of different mills and grinders that Cincinnati made at the time. This is great information to help you identify your old Cincinnati machinery, or to learn more about the evolution of their machinery.
We wrote an article on Cincinnati serial numbers. It can help you identify and date your Cincinnati machinery. It’s the most complete list we’ve collected, but if you have additional Cincinnati serial number information, please contact us. We’ll keep the list updated.
We have a whole lot more Cincinnati manuals that we haven’t had a chance to scan in yet. If you don’t see the Cincinnati manual you need listed below, feel free to contact us, and we may have it in our inventory. We literally have a few thousand more manuals in our inventory that we haven’t had a chance to get out yet. It takes a considerable amount of time to scan in and clean every page of these manuals to provide the best quality manual we can.
Here are the new Cincinnati Milling Machine Co. manuals that we recently added:
We hope you find the machinery catalogs and bulletins helpful. We take a considerable amount of time away from our tools to provide this information to you for free, because we truly believe that these old machines should be preserved. It’s really hard to find a machine built brand new today with the same quality and care that went to this old cast iron.
If you have any manuals or catalogs you would like have added to our inventory, please feel free to send them to us. We will scan them and post them online. We are expecting more machinery brochures and catalogs from HMS, so bookmark us check back soon. Share this with others.
The following information on Cincinnati Milacron milling and grinding machines serial numbers is from the second edition of Cincinnati’s serial number index from 1953 that was not released into circulation.
This is the most complete set of Cincinnati milling and grinding machine serial numbers I’ve ever seen, and this will continue to be a living and updated document as additional information is discovered. This includes significantly more serial numbers and information than the Serial Number Reference Book for Metalworking Machinery. I’ve included the original text from this document, and tried to organize it in a simpler format for online and mobile device viewing. If you have any additional information about Cincinnati serial numbers please comment below or contact us here.
THE index contained herein will identify any standard machine tool manufactured by The Cincinnati Milling Machine Co., since the beginning of 1933. By referring to the code on the next page the reader may also ascertain the year of order booking and lot number of the speciﬁc machine in question. Prior to 1933 several types of serial numbers were used. In general they involved the use of single preﬁx letters. Prior to 1912 a straight numerical sequence was used.
To identify machines not included in this index, or to learn any shipment date, write to the Order Department, Cincinnati Milling and Grinding Machines, Inc., Cincinnati 9, Ohio, Re. 2121, Teletype CI 27 7 , or direct Western Union Wire.

Machine Model Information
The Wording—“THE OLD MARK” was placed in use during the year 1938 to establish a year model for each new design machine as indicated by the following example:
THE OLD MARK
123 456 7890
Year 1938—Model Machine “EA”
A machine newly designed in the year 1938 by Engineering Dept., and placed in production the same year or a later year—say 1939—would be Model “EA”—1938, or Model “ER”—1939.
Current model letters are also included for each machine listed.
The Cincinnati Serial Number
Here is a typical Cincinnati Serial Number: 4A3U1K-110
This is the portion identiﬁed in the sections below. It is determined by the type, style, and size of the machine. Click on the section corresponding to the second letter. This code would be found in the “A Section”.
This portion identiﬁes the year of order booking according to the code below: Since the serial number is assigned at the order booking, the year of completion or of shipment may not always be the same as that indicated by this code. After 1953 all year codes start with number 5.
This is the 110th No. 3 Universal High Speed Dial Type Milling Machine (4A3U) order booked during “K” year (1941). It may have been completed one or even two years later. If there had been a major design change during the ﬁrst year,“1K“would have changed to “2K”, and this sequence number would have started over.
In 1973 the system was again changed to the following: the last two digits preceding the dash indicate the year of manufacture and the letter code no longer applies. Example: 49U78-000 Built 1978
Special CINCINNATI Machines which do not conform closely enough to any existing design are given the factory’s manufacturing order numbers for their serial numbers. These are usually six digits in length preceded by the year of order entry and a letter, and followed by a lot number, thus:
All that can be determined from this type of serial number is that here is a special Broaching machine ﬁrst authorized for building in 1941, and that this is the second machine of the type built—probably in a later year. The authorization date (41) is no index to shipping date, which cannot be determined from the serial number. The letter “M” indicates milling or cutter sharpening, “G” indicates grinding and “B” indicates broaching.

We’ve had a couple readers ask us questions about Hardinge HC & HCT chucking machines and metal lathes. We recently made available some more manuals for these Hardinge chucking machines. We have Hardinge operator’s, maintenance, and parts manuals for many different vintages, and for the different manual and automatic threading units that were on some of these Hardinge lathes. The Hardinge chucker lathes were workhorses, and even a worn out Hardinge HC & HCT can easily hold tight tolerances. These also had the nickname Kodak Lathe, which is explained below.
Hardinge Brothers, Inc. History
1919 Hardinge Cataract Quick Change Lathe
The American Hardinge Brothers’ origins go back to 1890 in Chicago, when Franklin and Henry Hardinge began developing watchmaker lathes. They purchased the Cataract machine line from Cataract Tool and Optical Co, in 1902. In 1931 Morrison Machine Products purchased Hardinge Brothers and moved them to Morrison’s operations in Elmira, NY. Hardinge Brothers, Inc. machines are well known for their superb quality and dependability. Their popular models are the HLV and the great HLV-H precision lathes. The HC and HCT chucking machines came after WWII. These models were also know as Kodak lathes, because Kodak wanted machines to help in the manufacturing of high quality lens rings, casing, and shells. The engineers from Eastman Kodak Company actually went down to Elmira, NY to work with the engineers at Hardinge to develop these lathes specifically to help with Kodak’s production. That was the original purpose of these lathes, but these lathes also turned out to be great on other jobs as well.
Hardinge HCT Lathe Pictures
We received several pictures from some readers looking for information and manuals for their HCT chucker metal lathes. The first set show a HCT with serial #26300, dated 1953. The cross slide was removed for repair and cleaning, and it is missing the threading attachment, which is the “T” in HCT.
Threading attachment shown above

This next set of pictures is of a Hardinge HCT chucking metal lathe. I’m not sure what the serial number is, but it is the same vintage of HCT lathe as the one above. Obviously, someone has added a VFD at the top left for variable speed control later, and this one is also missing the threading attachment.
Hardinge Manual & Automatic Threading Unit Attachment
Hardinge made both a manual and automatic threading unit attachment for the chucker lathes, which were the HCT models. The Hardinge chucker lathes don’t have a quick change gearbox to switch feeds for different threads. Instead the Hardinge have a threading attachment unit that follows what is called a lead screw with a certain pitch that is placed on the back end of the spindle.
Then you have to place the corresponding follower on the follower arm. This follows the lead screw which with the set pitch, and moves the tooling on the other side of the spindle so you can cut the threads. The following pitches for right-handed threads were standard: 12, 13, 14, 16, 18, 20, 24, 28, 32, 36, 40, 48, 50 and 60. Left-handed or special pitches could be custom ordered, and blank lead screws and followers were also sold so you could grind your own threads or leads.

Hardinge Lathe Catalog Information
Below are some excerpts from some Hardinge lathe catalogs about the HC and HC-AT that detail the specifications of these lathes. We also have Hardinge catalogs and bulletins in PDF format free to download here: Hardinge PDF Downloads
Operator’s, Maintenance, and Parts Manuals for Hardinge HC, HCT, and HC-AT
We have quite a few manuals available that cover the Hardinge HC, HCT, and HC-AT lathes. Here are some Hardinge manuals that would be useful for these models:
