Machine ID’d: Rockwell-Delta 20″ Wood Band Saw 28-350

 This gentleman emailed us about a Rockwell 20″ wood band saw that he wasn’t sure what model it was or much about it. This band saw was made around 1957 according to it serial number. Labeled with Rockwell Manufacturing Co.- Delta Power Tools Division. A lot of the machines that Rockwell-Delta made during this time didn’t have model or catalog numbers posted on them. This band saw is a catalog number 28-350, and the standard blade length was 144″.

Originally Sold:
This 28-350 band saw with the basic package was sold for $519.75 in 1957, which is equivalent to $4,413.95 today. Here is the original catalog page:

Instructions and Parts Manual:

We have a printed instructions and parts owner’s manual for the 28-350 and similar 20″ Rockwell-Delta band saws available at the link below. It covers a lot of the specifications of the band saw, and explains what kind of motors Rockwell recommends as well as how to properly install the motor and make adjustments. It also contains operating instructions, adjusting the table, blade tracking, and blade tension for this band saw with explosive view diagrams of all the parts.

Machine ID’d: South Bend 13″ x 6′ Metal Lathe Catalog No.1866-C similar to 166-C

We had one of our readers that wanted to learn more about his great 13″ x 6′ South Bend metal lathe. These South Bend lathes are beautiful machines They were built like tanks. As long as you install them properly, keep them clean, keep them trim, and oil the lathe properly they should last forever.

The serial number of his lathe was No. 50328 and the catalog number was stamped 1866-C as you can see in the picture below. This information dates his lathe around 1931. The reader wanted some clarification as to if the 1866-C was misstamped, because most of the information and advertisements with a similar machine show the catalog number as 166-C.

 

The 1866-C is a real and correct catalog number for your lathe. The difference between the 1866-C and the 166-C is the 1866-C was considered a “Tool Room Precision Lathe”, which came with various attachments like the collet attachment, taper attachment, threading dial, etc…

This particular South Bend lathe is part of the “N” series, which is distinguished mainly by the design of the apron. The “N” series wasn’t in production for very long. South Bend started producing them around 1930. It was replaced by the “R” series after 1934, and that is what South Bend used to the end. They sold the “N” until about 1937. There is always a lot of overlap with South Bend on some of their parts.

Here are some pictures of the South Bend Lathe after it has been cleaned some.

 

Manuals for South Bend 13″ x 6′ Metal Lathe Catalog No.1866-C

We have a few manuals that cover this South Bend 13″ x 6′ Metal Lathe Catalog No.1866-C. We have new revised parts manual that shows the main parts of the lathe here:

 

These are very helpful when trying to take the the lathes apart or put them back together. Also, locating parts can become easier, because most parts have the part number casted into them.
We also have a manual that shows explosive view parts break down diagrams of the accessories for these larger lathes like the, taper attachment, milling attachment, threading dial, turrets, collets, steady rest, etc… here:
A lot of people didn’t realize the the threading dial was an accessory. It seems like a common part today, but it is actually possible to do threading well without the dial and the version of How to Run A Lathe explains this procedure.
South Bend basically made one book for operations that covered all their lathes, but it is important to find the one that covers the correct vintage, because they made lots of changes to these lathes over the years. They keep the book with the same title “How to Run a Lathe” all through out the years, with different editions. The edition we have here covers this style of lathe, and we’ve enlarged it so it is easier to read:

What are the Differences Between Step-Pulley Vs. Variable Speed Drill Presses

Drill Press Articles (Part 3 of 5)

 Step-Pulley vs Variable Speed Drill Presses

There are two different types of speed control systems for drill presses — step pulley and variable speed systems. The vast majority of drill presses bought and manufactured are step pulley drive systems. They usually have two pulleys with 4 to 5 different positions or steps to configure the different speeds. These are simpler, easier to produce, and cost less; however, they can be more difficult and more time consuming to change speeds. This usually isn’t a problem for most people, because speed changes aren’t needed often, especially if you are working with the same type of material and bits. This is the type of machines that were commonly purchased by factories for assembly line work where they were set up to do the same task over and over.

The variable speed drive systems are a lot more complex and vary greatly in their mechanisms for changing the speeds. The variable speed drive drill presses usually have a dial on the front that controls a mechanism that changes the working diameter of the spindle pulley, which changes the speed of the spindle. This change is done while the drill press is operating. Some people have retrofitted drill presses with variable speed frequency drive (VFD), and some manufactures are building them this way now. VFD’s control the speed of the motor electronically, and don’t require any mechanical changes. Variable speed drill presses are usually more preferred by machinist that work with a variety of bits and different types of metals where you are constantly changing speeds.

Bench Top Vs Floor Standing Drill Presses

Drill Press Articles (Part 2 of 5)

Bench Top Vs Floor Standing Drill Presses

Let’s discuss the different styles of drill presses. There are bench and floor versions of nearly every large drill press model. Mechanically they are the same, and most manuals include both versions. Usually the only real difference between the two versions is the length of the column and the size of the base. Sometimes the floor model will have a bigger column, but I’ve found this to be very rare.

http://www.ozarkwoodworker.com/ROCKWELL-15-Drill-Press-Model-Operator-Part-Manual_p_598.html

The advantage to a floor standing model is obvious. If you have to drill or mortise the end of a really long piece of material you can, but unless you get into cabinet or furniture making, this usually isn’t necessary. I have both in my shop, and I use the benchtop version 90% of the time. Plus, I set it on a cabinet with all my bits and tools easily accessible underneath. Both bench and floor are usually contained in one manual like these two Rockwell drill presses are covered in the same manual here, and as you can see their heads are identical. Each one has their own place and advantages.

How to: Measure and Size a Drill Press

Drill Press Articles (Part 1 of 5)

Drill presses have been around for quite a while. We use lots of different ones in our shops for different operations, and we have manuals for many of them. They are designed mainly to help keep precision while drilling holes. Of course, drill presses can be used for many other things like sanding, wood shaping, and more, but we’ll get into that later in this series of articles. There are lots of different sizes and types of drill presses, and this series of articles is to help you identify what type of drill press you have or what type of drill press you may want to purchase.

How Do You Measure a Drill Press?

The first thing people ask us is how to size a drill press. What is the difference between a 15″ or 17″ drill press? The measurement is simply the distance from the center of the spindle to edge of the column, then doubled. So if you measure 7.5 inches, you have a 15 inch drill press. This is referred to as the swing of the drill press which is the largest diameter piece this drill can handle. This is similar to the way a lathe is measured.

Machine ID’d: Atlas V42 10″ Metal Lathe Restored

Here is an image from a reader that nicely rebuilt and restored this Atlas 10 inch metal lathe model V42 with serial number 05140. This is a older version of the Atlas 10 inch lathe, because it has babbit bronze bushings and doesn’t have a pull knob to engage the power cross feed on the apron. We actually used to have a similar model in our shop.

 

The reader said that he had our parts and instructions manual for this lathe, which we have here:

 

 

This manual covers the following models.
  • For Atlas timken bearing lathes:
    with horizontal countershaft-Cat. Nos.: TH36, TH42, TH48, TH54
    with vertical countershaft-Cat. Nos.: TV36, TV42, TV48, TV54
  • For Atlas babbitt bearing lathes:
    with horizontal countershaft-Cat. Nos.: H36, H42, H48, H54
    with vertical countershaft-Cat. Nos.: V36, V42, V48, V54
  • For Atlas quick-change lathes:
    Cat. Nos.: QC42 and QC54

This manual does cover the basics. It explains lubrication, and labels the different controls of the lathe. The reader said that he wanted more information about the operation of the lathe. He’s not the only person that has asked us about this, and that is why we carry the Manual of Lathe Operations and Machinist Tables books, which is full of almost everything you would want to know to get started, plus it contains information on the gear and machinist tables for threading.

The problem with these books is that Atlas and Craftsman sold thousands of these over many decades. They made changes to the books as they made changes to the lathes, but they never stated on the cover or in the book which manual covers which vintage and size of lathe. We’ve collected over 25 of these books and have done the research for you, and we have the one that covers this lathe at the link below:
