This is a foundation class designed to provide what you need to know to safely operate the machine shop’s CNC Lathe.
We’ll cover CNC lathe basics beginning with the details of the machine, understand motion on the Z & X axes in the lathe, various cutting tools, the tool library and diameter & Z-offsets. We’ll also touch on different ways to generate g-code (the language that instructs the CNC machine what to do and where to do it), including the Centroid Interactive Conversation mode for the lathe. Finally, we’ll create some simple g-code, cut some air and if there’s enough time, cut some material.

In this 3 sessions class you will learn how to make a hammer from aluminum and brass as you learn basic metal machining techniques.
Machining operations that will be covered in the class include basic metal turning, external thread cutting, knurling, chamfering, cutting off, milling a flat on a round work piece, drilling, and tapping threads.
The hammer, which will be yours to keep, will have a brass head and will be useful as a "positioning" hammer. If you want a hammer head other than brass that's 1¼ inch diameter, bring the material to the class.
A materials fee of $20 is included in the class tuition.
Before the class, students should view the following YouTube videos on how to make this type of hammer:

While building a nut and preparing a threaded rod you will gain experience with our lathe and mill. You will also practice layout, facing with the mill, drilling, taping, adjusting a four jaw chuck, using the cut off saw, and filing a chamfer.
This class is suitable both as a beginning class and for those who are fairly new to the shop and wish to gain experience.
You will not only get a chance to gain confidence in using our shop tools, but have a lovely square nut that spins freely on your threaded rod demonstrating your proficiency with threading.
There will be a $5 material fee included in the price of class.

Blacksmithing is heating pieces of wrought iron or steel until the metal becomes soft enough for shaping with hand tools, such as a hammer, anvil and chisel. Heating generally takes place in a forge fueled by propane, natural gas, coal, charcoal, or oil.
This Basic Blacksmithing Class is a 2-session class of three hours each. These two three hour hands-on class allow you to learn basic techniques such as drawing, bending, and twisting and then advance to splitting, scrolling, and punching. You will be able to design, complete and take home simple projects such as bracelets, triangles, hooks, spoons, tools and more. The class will include an introduction to heat treating if appropriate for the projects undertaken.
Location: This is an off-site class.

Prerequisite: Introduction to the Milling Machine class or equivalent.
This is a foundation class designed to provide what you need to know to safely operate BARN’s CNC Mill, and is the requisite for ongoing CNC classes. We’ll cover CNC basics beginning with the details of the machine understand motion on the X, Y, & Z axes that define the work envelope, how to hold material, various cutting tools, and the Standardized Tool Library and height offsets. We’ll also touch on different ways to generate g-code (the language that instructs the CNC machine what to do and where to do it), including the Centroid Interactive Conversation mode. Finally, we’ll create some simple g-code, cut some air and if there’s enough time, cut some material.
A materials fee of $10 is included in the price of the class.

Are you always impressed how some people in the Machine shop can do the the most seemingly difficult things. Come and learn some of Peter's tricks and techniques. You will be amazed and astounded, you might even pick up a few new ideas to use on your own projects.
In this class you will learn some the the tricks and methods that the instructor uses to make good use of the tools in the shop. Finding centers, tapping techniques, deburring, using the micrometer, using the grinders, work holding etc.
This is a BARN holiday. Doors will be locked to members and non-members.

Learn to cut threads on the Hardinge Lathe
Threads are one of the most basic ways of joining two pieces. In this class you will learn the basics of cutting (chasing) threads using the Hardinge Lathe. You will be introduced to threading basics and then learn now to set up and cut threads using both dies and actual machine cutting. If there is time you will also be introduced to thread cutting on the Clausing Colchester Lathe.
One of many reference texts on machine threads can be found here.
A $10 materials fee has been included in the price of class.

Fix-It Saturday (FREE -- Members & Guests)
Fix-It Saturday takes advantage of the equipment and skills of the Metal Fabrication group at BARN to meet the challenge of repairing items brought in. Requested repairs should be focused on metal or related electrical projects. Your hands on participation in the "fix-it" process is encouraged.
See what we can do, what suggestions we can make, or what other avenues you might pursue if a fix is not at hand.
(No wheeled vehicles, please).
Registration is not required. Fix-It Saturday is free and open to members and non-members.
Please Note: Fix-It Saturday runs concurrently with an Open Studio available to qualified users. Open Studio users must register and pay the required materials fee for the Open Studio that is also held on this day. Please click here to register.

In this 4 session class (two hours each on weekends) you will learn how to make an air or steam powered engine from aluminum and brass as you learn basic and intermediate metal machining techniques.
Machining operations that will be covered in the class include basic metal turning, chamfering, cutting off, milling rectangular components, drilling, and tapping threads. CNC milling will be demonstrated for the main frame and optionally for the flywheel.
The engine, which will be yours to keep and will have an inlet that can be pressurized with air or steam to power it.
Here is a link to an animated .gif file that shows the engine in operation: https://i.imgur.com/h3UoK34.gif . The animation was generated last summer by our intern, Rose Bandrowski.
Before the class, students may view the following YouTube videos on how to make this type of engine. The engine in the course is simpler than the one in the videos but the principles and techniques are similar:

Beginning with a hexagonal aluminum rod you will gain experience making a bolt on our Hardinge lathe. you will practice facing, turning, threading, parting and chamfering operations.
This class is suitable both as a beginning class and for those who want additional experience.
For those that have taken the make a nut class this is your opportunity to finally have a matching bolt.
In this 2 session class you will learn how to safely use the Vertical Milling Machine. The Mill is one of the most useful machines for making simple to complex parts out of metal or plastic. We will cover work holding, cutters, the rotary table, and how to deal with different materials.
After completion of the class you will be able to make that part that they just don’t have at the hardware store. You will leave the class with a coaster or other useful item that you have made.
Additional Materials Fee of $10 for plastic and metal used during class will be added to the tuition when you register.

This class will teach you use a milling machine to perform an operation called pocket machining. The pocket is a rectangular feature that has length width and depth. The skills you will gain are layout, edge finding, setup, milling, use of the digital readout and some shop math.
This class is most suitable for those that have had at least one other hands on class.
This TIG welding class is an opportunity to dive deeper into TIG and to improve your skills under the eyes of a highly versatile welder and skilled teacher. The class is for students who have had TIG #1 and TIG #2. It will focus more on technique than fabrication.
Jeremy Loerch is both a skilled welder and a skilled teacher with a strong reputation for his own programs and Park Department welding programs. He also teaches forging (blacksmithing) and knife making for BARN.
