Description of the class:

Students can bring projects (call to discuss your project well in advance of the class) or work on one of the many projects that are available in the shop.  I always encourage challenging projects even if you are a total novice to the craft.

On Friday morning I start off by defining an easy to understand  vocabulary of the Metal-Shaping craft.  With each defined term I demonstrate the several  established  techniques and some of my own to create perfect sheet metal panels.  Late on Friday students  practice  the various shrinking , stretching, and planishing techniques that I previously explained and demonstrated. On Saturday projects are started.  I have found it is best to group students in teams working together on a project, each student reinforces the other. If someone prefers to work alone on a project that is not a problem.  If there are six or more students in a class I bring in one or more instructors to help with the class.

The project part of the class reinforces what you have learned.  Usually it takes till Sunday afternoon for the theory, practice, and understanding of the potential of the various tools to start clicking and the confidence level to start building. Smiles start to appear as very complicated projects start to take shape-confidence builds, discussions generate, and ideas start to gel .  The power of craftsmanship and creativity kick in and that is what it is all about. The unity of craftsmanship and creativity are one of life’s greatest pleasures.

To get an idea of the facility I have posted pictures of the tools that are in the shop,I will have more by the end of 2017. We’re currently building a double headed  large scale power hammer ( see picture-the hammer should be finished within 30 days ) so that hammer techniques can also be a major component of the class.  By the end of 2017 I intend to have two double headed full size power hammers and ten  large English wheels for students to use. All the metal shaping tools are of my own design and built in the shop.

Payment can be made by clicking on the desired month below on this page. Payment can also be made over the phone by credit card please call (508) 347-7749

The class starts at 9:00am till noon. One hour off for lunch (free lunch included everyday). Class resumes at 1:00pm and runs through 5:30pm.  Break one and a half hours for supper ( there are at least twenty restaurants in the area.) The class starts again at 7:00pm and runs to till 10:00 pm.


Days Inn in Sturbridge 508 347 1978 ( 10 miles away) offers my students their corporate rate ( around $60.00 per night you must mention you are attending the class)  The Days Inn is an excellent motel, I have had zero negative feedback from students. There are at least 20 other motels in the area to choose from.
