Flared bead spacers are easy to create with this 3-mandrel set from Fretz. Each mandrel has two halves, one of which slides along a central rod of the other, keeping the two aligned. The sturdy steel base keeps the mandrel upright and stable during flaring and the included wood stand (not shown in photo) keeps the tools organized. The three mandrels are sized for seamless tubing with inside diameters of: 3.5–4.4 mm, 4.5–5.9 mm and 6–7 mm. A variety of spacers can be created by varying the length, diameter, and thickness of your tubing. The hammer shown in the photo is not included.
