摘要

The making of crankshafts has been described in articles in this and other magazines so many times that I did wonder if it was worthwhile adding yet another. However, I made my crankshaft from high tensile steel and I suspect some model engineers are reluctant to use this type of material due to the perceived difficulty in machining it compared with mild steel. Plus I have not noticed many articles devoted to machining HT steel from a model engineer's point of view. I cannot deny that high tensile steel takes longer to machine and will blunt, the edge of your cutters more readily than mild steel, but, in my view, it is a price worth paying for its several advantages (when required), the most obvious of which is its greater strength. The grade of steel I specified on my drawing is EN24T, which is supplied already heat treated to around 32 Rockwell C and is in common use. The increased hardness does offer some increased wear resistance but is not sufficient to make it significantly more difficult to machine than an annealed grade, in other words it's a sort of half way house between a fully hardened and ground shaft and one made from unhardened mild steel. The increased hardness also makes it more resistant to damage when holding it for subsequent machining operations and of course accidental damage.
