A mandrel (pronounced /ˈmændrɨl/, and also spelled mandril; in American English also called an arbor) is either an object used to shape machined work.
The JD2 is a mandrel bender.

This is getting kinda funny. Some cut and paste, not that any of this matters. My bold and italics
Mandrel Bending
There are various methods available to bend tubing. Mandrel Bending (Rotary Draw where a mandrel supports the inside of the tube to avoid collapsing). This produces round, smooth, and wrinkle free bends with centerline radius between 1 and 5 times the outside diameter.
Boost Bending
A boost bender assists the bend by pushing the tubing as it is being bent around the radius. This improves both the speed of production and quality of the bend.
Hydroforming
Another type of bending is Hydroforming (Internal fluid supports wall while being pressed into a cavity). We specialize in Pre-forming tubes for Hydroforming. We can Mandrel Bend difficult shapes, which our customers Hydroform in heavy presses.
Compression Bending is another form of bending offered in the tube industry, it is a process where the tube is pressed into shape using a simple machine that forces the tube around a radius without any interior support. Most automotive exhaust pipes, with their many flat spots and wrinkles, use Compression Bending.
CNC Mandrel Bending
Computer Numeric Controlled (CNC) Mandrel benders give the capabilities to bend high volume multiple bend parts in much less time. They include multiple stack benders capable of more than one radius to 6" diameters.
Roll Bending
Roll bending differs from Mandrel Bending in that the bend is not supported by an inside mandrel. The process is simple to set up, and allows for an infinite amount of bend radii, without re-tooling.
