Industrial Sewing Fast Pass Test

Introduction

Before using the industrial sewing machines at TinkerMill, members are required to take the Industrial Sewing Machine Certification Training. The purpose of the training is to teach the proper usage of the equipment is order to ensure the safety of the user and to help prevent damage to the equipment. Members who have extensive prior experience with industrial sewing machines may consult the shop captain to request a "Fast Pass" certification test in order to get certified without taking the class. This page describes what the "Fast Pass" certification entails and can help a member determine if they may be a candidate for the test.

“Fast Pass” certification is available only to TinkerMill members, must be approved by the shop captain, and costs $25, which is a non-refundable fee. If the member is unable to pass the test, then the certification fee will be credited towards the cost to take the certification class at a future date.

Administration

This section discusses the "Fast Pass" test eligibility criteria and administration process.

• The member must be pre-approved by a shop captain and pre-pay the test fee in order to take the "Fast Pass" certification test.
• The test can be administered by a shop captain or one of the industrial sewing instructors.
• The member may select either the Kingmax or the Juki and may adjust the speed to their comfort level. Materials such as fabric, thread, needles, and poly webbing are provided.
• The test is divided into two sections - Working Knowledge and SKills Demonstration. The Working Knowledge portion is an oral test in which the member must describe and discuss fundamental aspects of the machine and industrial sewing techniques. The Skills Demonstration is the hands-on portion of the test in which the member must prepare the sewing machine and perform actual sewing. The member must pass the Working Knowledge section of the test before proceeding to the Skills Demonstration.
• The test administrator may stop the test at any time if it is clear that the member cannot pass it. The member cannot proceed to the Skills Demonstration if they are unable to pass the Working Knowledge section.
