About product

The DSPIAE AT-CR stepped forming mandrel

A metal mandrel stepped into twelve diameters, on which wire and photo-etched parts are bent into regular arcs, rings and spirals. The range runs from roughly one to twelve millimeters, so it covers everything from small eyes and loops up to larger hoops and frames. A bend over a mandrel is fundamentally different from a bend made with pliers: the radius is the same along the whole length and repeatable, whereas pliers leave a kink and jaw marks where they grip.

What it is for

Typically for eyes and loops of wire, rigging rings, hoops, hose loops, curved photo-etched strips, rims and covers. It comes into play on ships, aircraft and vehicles and everywhere an arc is meant to be regular.

How to work with it

  • Wind the material on gradually and press it against the mandrel along its whole length, not just at the start.
  • Count on a bent part returning slightly once released, so bend it on a diameter one step smaller.
  • Bend photo-etched parts slowly, as a quick bend puts a kink in thin sheet.
  • Brass and steel can be annealed before bending; the material then bends without springing back.

Who it is for

The mandrel will be appreciated by builders of ships and aircraft who work with wire and photo-etch and by everyone who makes details of their own. It is not a bender for sharp edges, which is what photo-etch benders with jaws are for, but a complement to them.

Before forming it is good to draw the arc you need on paper and compare the finished part with it. The eye judges a radius badly and on a model the inaccuracy only shows once the part is glued on. Protect your eyes when working with wire, as a released end springs back.

FAQ

Twelve steps in a range of roughly one to twelve millimeters.

Pliers leave a kink and jaw marks where they grip. Over a mandrel the radius comes out the same along the whole length.

The material springs back slightly once released. Bend it on a diameter one step smaller, therefore.

It does not. A bender makes sharp edges, a mandrel regular arcs. They are complementary tools.
