I'm unclear why the recommendation has been for "drill rod" (i.e.tool steel) for the parts that essentially hold the parts to a hinge together. It would seem that a plain 1018 cold-rolled steel would be strong enough. For easy machining, even 12L14 would seem to be preferable, although I don't know if that's legal in the EU, given the slight lead content. Anyone care to shed some light on this? And if "Drill Rod' is the preferred material, what *kind* of steel? i.e. O1, S7, A2, D3, W1, M2? Just curious--unless the application is for a shaft subject to torsional loads or needing a cutting edge, I generally use cold-rolled mild steel--it's inexpensive and machines well. --Chuck
