That is a mandrel.

The JD2bender leaves no kink,, The dies as sold by JD are sized so it won't kink reasonably thin material.

Using a mandrel in that JD bender is a waste unless you get a smaller radius die to take advantage of the mandrel. Then you need to set up a frame on the back setion of the tube to keep the mandrel from pulling through the bend along with the material. Then it will need a way to retract the mandrel from the bent material. Real mandrel benders use a big hydraulic ram. That screws into the back end of that mandrel you pictured.

Try looking on ebay.

later, mikey
