Step Mandrels are a good economic solution to forming shorter cylinders. 
 
These Step Mandrels will work well for short cylinders, but they won't be as effective as our Cylinder Forms with Reference or Cylinder Forms without Reference for longer cylinders. 
 
The smaller Step Mandrel offers diameters of 1mm, 1.5mm, 2mm, 3mm, and 4mm.
The larger Step Mandrel offers diameters of 5mm, 6mm, 7mm, 8mm, and 10mm.
