Valve springs

To be able to produce 25 equal valve springs I made a simple tool to bend the wire.

(A description of the tool can be found in Bouwbrief 91, p. 13/14:  Materiaal en Gereedschap 45: Hulpstuk voor het maken van speelklep veren. author: Johan de Vries)

Material used: 4 m. of spring steel wire of 1 mm diameter. Length of the legs 5 cm.

The steel wire is bent over a pin of 6 mm. (1 loop) by means of a lever.

 The ends are then bent with a small vise

The result: a pile of 28 springs
