Objectives At the end of this training you will be able to: 1.Explain the key features of the tube bender 2.Layout tubing to make bends 3.Use the tube bender to make a variety of bends 4.Diagnose problems with tube bends 5.Design tube runs for safety and maintenance
TurnPro Indexing Handle Tube Bender Features Makes bends greater than 90° in a single operation Eliminates crossed handles No assembly and reassembly of bender handles Durable Construction – Suitable for heavier wall tubing – Vise mountable 1/4, 3/8, 1/2 in. (6, 8, 10, 12 mm) sizes Training available

Layout Sequential Bend Method 1.Add the lengths or all section together to estimate the overall length of tubing required for the job. 2.Mark the starting point (reference mark) for your project. – Remember to make all marks completely around the tube. 3.Measure from the reference mark to the vertex of the first bend. – The vertex is the point where the center lines of the two legs of the angle meet. 4.Bend the tube. 5.Using the vertex of the previous bend as the reference mark, mark the vertex for the next bend the next bend. 6.Repeat steps 3 and 4 for the next bend
Sequential Layout Reference Mark Vertex 3 in. 1.Add the lengths or all section together to calculate the overall length of tubing required for the job.
Sequential Layout 2.Mark the starting point (reference market) for your project. Remember to make all marks completely around the tube. Reference Mark
Sequential Layout 3.Measure from the reference mark to the vertex of the first bend. The vertex is the point where the center lines of the two legs of the angle meet. Reference Mark 3 in. Vertex

Layout Calculations Reference Mark 3 in. 6 3/16 in. 3 in. in. Adjustment (Gain) Calculations 3 in. + 3.5 in. – 5/16 in. = 6 3/16 in. 6 3/16 in. + 3 in. – 5/16 in. = 8 7/8 3.5 in. New Calculation 9 1/2 in. – (2 x 5/16) = 8 7/8 in.
Imperfect Bends Common causes of imperfect bends May be caused by: Not having the mandrel forward far enough in the tube Bending thin wall tubes without a mandrel Trying to bend too short a radius Bending smaller diameter tubing in a larger radius block. Sometimes produced when thin wall tube is bent without a support mandrel. May be caused by the tube slipping in the bender. A kinked bend may also result from the use of non-annealed tubing.
