The 411 on Roof Drains at Metal Craft Spinning and Stamping

Over time a flat roof may collect too much water, which will cause flooding.  You can easily prevent this by installing a roof drain. Roof drains are used to convey stormwater from the roof to the retaining area or the drainage sewer. Stormwater is generally received from the roof drains and moved to one of three places:

  1. Your city’s sewer system
  2. A retention pond or reservoir
  3. Left on the ground to naturally evaporate

Automated metal spinning can create roofing drains with a wide range of diameters as well, which is why manufacturers use metal spinning to build roofing products for all shapes, materials, and applications.

Metal Craft Chosen to Spin 2019 Good Deeds Cup

The Chevrolet Hockey program aims to inspire positive values in young Canadians through hard teamwork and sport and also encourages the participants to perform positive deeds in their communities. The program enables Chevrolet to donate to causes across Canada on behalf of Peewee hockey teams. Players have performed hundreds of good deeds since the 2016/2017 culmination. Good deeds encouraged by the program include voluntary work at food banks, visiting an animal shelter, or driveway shoveling in the community.

However, the activities involved are limitless, as players are free to come up with and implement any suggestions. Good Deeds Champions receive different prizes, including the coveted Chevrolet Good Deeds Cup with the team’s name engraved. But how exactly is such a celebrated championship cup designed and made?

The Good Deeds Cup Design


Hockey Canada approached Jimmy Rogers of 39 Design and Engineering Inc. to design the Chevrolet Good Deeds Cup. He then contacted Metal Craft Spinning and Stamping to spin the cup portion of the trophy itself. This unique project allowed us to showcase our manual metal spinning capabilities while supporting a worthwhile charitable program.

The client asked us to fabricate the Good Deeds Cup from brass. This metal comes as a flat sheet with excellent formability properties, allowing for a smooth transformation into a cup. While brass is already a ductile metal, for this project we put it through several annealing cycles to make it more malleable. The annealing process involves treating the metal with heat to increase its ductility, but multiple rounds of annealing were necessary as brass heats up rapidly and gets hard quickly.

metal-spinningTo create a high-end, long-lasting cup, we turned to our senior metal spinner, whose 30 years of hand spinning experience was the perfect match for the project. Our senior metal spinner has handled a wide range of complex pieces over the years, which means he could handle any issues that may arise to produce an exquisite masterpiece.

Since the end product was only one piece, the operator chose a hand spinning lathe instead of a CNC machine. Aside from the low volume, a hand spinning lathe is also ideal when you need maximum control. Manually spinning the piece allowed our senior metal spinner to feel the flow of the material.

Crafting this sophisticated piece required significant preparation and time. The spinner took five hours to produce the Good Deeds Cup. It was then polished and shipped to our client.

About Manual Metal Spinning

A typical hand metal forming process takes the following steps:

  1. The operator mounts the mandrel chuck to the headstock. He then fixes the blank in position by advancing the follower block attached to the tail’s headstock.
  2. A combination of a tool rest and pin serve as a support system for the lever arms. This arrangement gives the lever arms enough leverage to apply sufficient pressure to the blank against a forming tool like a roller.
  3. A pass in manual metal spinning refers to one movement of the roller across the blank’s surface. The operator needs to run multiple passes to form one complete part. This can be achieved by increasing the pressure on the blank using the lever arms gradually to reduce the blank into the desired form.

For mass production and repeatable precision in large volume metal forming, Metal Craft Spinning & Stamping uses our CNC metal spinning machine rather than a hand lathe. This technology automates the passes, transforming the blank disc into intricate pieces within minutes.

Bringing Metal Spinning to The Modern Age

Metal spinning has evolved significantly over the years. Though the concept remains the same, modern equipment and advanced technology have transformed the process into a more viable and affordable option for the manufacturing industry.


What Is Metal Spinning?

is known by many names, such as spin forming, spinning, and metal turning. Regardless of the name used, it is a metal forming process which rotates a tube or disc of metal at a high rate of speed to produce hollow objects or components. A common factor in these hollow objects is their typically circular cross section. 

The best uses of metal spinning include creating prototypes and manufacturing parts which require high internal and external pressures. 

Traditional Metal Spinning Process

The basic concepts of the metal spinning process have not changed a great deal since spinning was first introduced as a manufacturing tool. The essential steps include: 

    • Mounting a mandrel chuck on the headstock of the lathe.
    • Mounting a follower block to the tailstock.
    • Clamping of a circular blank by advancing the follower.
    • Pressure is applied to the blank via a roller or other forming tool on the lever arms, using the tool rest and pin to provide scissor-like support and leverage to the lever arms.
  • The roller moves across the blank in a series of passes until it forms the completed part.

Modernization of Metal Spinning

metal spinning automation Manual metal spinning, which came to North America in the early 1800s, has evolved into a more modern process. The technological advances of our modern age have combined to automate the process, making it faster and improving repeatability. As such, automation has made metal spinning an even more reliable and cost-effective manufacturing option. 

Automated metal spinning makes use of computer numerical control (CNC) in place of hand spinning. CNC is a method of subtractive manufacturing technology, which follows a computer aided design (CAD) model along with a variety of cutting tools to remove material from a blank in order to produce the desired component. The major advantages of CNC spinning over hand spinning include: 

  • Higher level of accuracy and consistency over an entire production run
  • The mitigation of human error risks through the autonomy of CNC machining and reduced touches.
  • The necessity of fewer personnel for high capacity production runs
  • 24/7 operation using machines, which cuts back on manpower and operating costs. 

Besides these advantages, CNC metal spinning allows for the turning of a broader range of materials than hand spinning, including less malleable materials. The materials formed using CNC spinning include:

Spinning, Stamping, and Hydroforming: Which Works Best for Your Application?

Most manufacturers consider metal spinning, metal stamping, and hydroforming to be specialized and narrowly focused processes, but actually, these metal-forming methods are used in industries as varied as commercial construction, interior design, heating and climate control, and agriculture. Manufacturers use spinning, stamping, and hydroforming methods for products ranging from satellite dishes to funeral urns.

Understanding the benefits of each process as well as where they overlap will help you decide which metal forming technique best suits your application. Below, we’ve assembled an overview of the three main metal forming practices, and we also outline the ways they could benefit your production line.


Metal Spinning

Metal spinning produces hollow parts in typically circular cross sections. This low-cost process efficiently allows you to create large volumes of cylindrical objects with minimal waste, and its tooling’s innovative design allows you to make changes to the production process at minimal expense.

Metal spinning can create objects with diameters ranging from one inch to eight feet. Manufacturers use metal spinning to build products including roofing, lighting, stainless steel bowls, engine components, musical instruments, brass vases, and satellite dishes.

Metal Stamping

Metal stamping uses precast dies to form flat metal sheets into different shapes. Because metal stamping requires less machine use and fewer laborers, it incurs fewer production expenses than other techniques.

Well-designed metal presses can punch, bend, notch, and emboss sheet materials as needed. Parts formed via metal stamping often appear in farm equipment, brackets, caps, and ventilation systems as well as many other industries.


Hydroforming uses oil pressure to shape cold-forming metals such as aluminum and stainless steel into durable, yet lightweight, pieces. The seamlessly bonded end products feature a high stiffness-to-weight ratio, so they meet the required tightness tolerances. 

This cost-effective method creates components via single-stage production, which also makes it easier to process large amounts of material at a time. Metal formers use hydroforming to build lighting fixtures, satellite antennae, and a wide range of automobile parts.

Which Method Best Fits Your Application?

Each metal forming technique offers unique benefits and drawbacks depending on its application. Manufacturers must also take their desired volume sizes into account when selecting a metal forming method. 

  • Metal spinning works best for prototyping and parts with high internal and external pressure
  • Metal stamping quickly fills both low- and high-volume orders and precisely cuts complex shapes
  • Hydroforming produces large, complex parts that require original finish maintenance, and can yield annual volume runs both large and small
