bending flat stock with arbor press
I would like to make an accessory for my 3 ton arbor press for bending thin stock. Basically I need a V block and a wedge attached to the ram. I have tried using a standard V block which works ok for messing around. I think I need a V block that is actually a bit less than 90 degrees so I can over bend enough to compensate for the spring back. So the first question is how much less than 90? The second question is how to make it? Cutting a 87 degree angle seems a bit tricky with a mill. The only idea I can come up with it to rough it out with a bandsaw and then use the shaper to cut the sides. chuck |
