One of the many challenges facing practical student workshops is the proliferation of rapid prototyping and similar technologies. 3D printers have enabled students to take ideas and concepts further than ever before and sometimes to completion. The only limitations at this stage are the materials available for the manufacture of components and prototypes on 3D printers. Traditional manufacturing processes like fabrication and machining are still sometimes required to complete projects. This has seen a greater demand and workload for traditional machine shops and trades people. Some of the manufacturing work has to still be completed by skilled experienced trade's people but some of the simpler less complex machining and fabrication tasks could be easily completed by unskilled students with basic training and minimal supervision. We needed to come up with a system that provided students access to industrial fabrication and machining equipment in a safe and productive environment. The peer support system provides a framework enabling students with little or no machine operating skills to safely access industrial equipment with minimal staff, supervision and danger of injury. This paper is a justification of these concepts, interest, approaches, and practices of the peers support framework and philosophy.

The design and performance of an eddy current damper for the Labshare remotely operated "Shake Table" multi-storey building vibration rig is described. The damper comprises stationary E-cores on either side of a copper plate attached to each storey. An approximate formula for the damper retarding force F is derived, of the form F = âkuI2 for plate velocity u and E-core current I, and a criterion for its validity is established in terms of the magnetic Reynolds number. A close fit to measurements of the force using a load cell is obtained for k = 0.401 N/(msâ1 A2). This was about 12% lower than the force determined by three-dimensional (3D) finite element analysis (FEA) using ANSYS 12.1, but the error can be attributed to manufacturing imperfections. Students can use the force formula in their investigation of closed-loop control of the Shake Table vibration. More generally, a formula for the force constant k can be used for the approximate design of any similar E-core damper.
