Office Hours

If you are new to woodworking and don’t know where to begin, sign up for Thursday “Office Hours” and we can help you come up with a plan! We also recommend checking out the Shop 61 playlist on our YouTube Channel. Office Hours are the best time to get help designing or choosing a project, to have more involved woodworking questions answered, and to tour the woodshop. Woodshop sessions and office hours are scheduled through our calendar.

Machine Use

BLDG 61 “Guided Access” is time to use the tools. They are NOT group classes. Sessions are COLOR-CODED based on the level of supervision a specific tool requires. Tools in the ‘Yellow’ category require the least staff guidance. Tools in the ‘Green’ category require some guidance. And tools in the ‘Pink’ category require the most supervision. The machines available in each session are listed below. Staff are not able to change your category. It is up to patrons to select which category provides access to the tools they need. If they do not yet know which tools they need, patrons should attend “Office Hours” to make a plan for their project.
