Video title: How to Roll a Cone – Midland Fabrication
In this video students James & Luke talk us through how to roll a cone in a set of pinch plate rolls. The cone is stage 1 of constructing a pot belly wood heater.
The unit of competence that this is aligned to is MEM05010C Perform Fabrication Forming & Bending. The students are nearing the end of their trade training at TAFE. They are completing a certificate III in Engineering Fabrication.
