hi steve,
thanks for adding to this.
it proves my fears of useing another material, right or wrong there will always be a chance to say you used the wrong material.
we did look at other materials available in the uk from the start, and prices.
the price of E40b in the round over here to machine billet cranks was coming in at £500 per crank. we couldnt get it big enough in bar.
BUT we could get EN30b big enough in bar, at a price of £50 per crank. then large sections could be laser cut out to reduce machining costs.
thanks tony
