yoeddynz Posted October 18, 2012 Author Share Posted October 18, 2012 Sweet- can you remember what grade steel you used? Our lathe at work should just be able to handle it. It's old and worn but I can work around that. Saw a bounty item on trademe- looks very similar to v6 one but bigger. I need to find out more...

RUNAMUCK Posted October 18, 2012 Share Posted October 18, 2012 I can't rememeber exactly. But since I had no job, no money, and no hope at the time, I think it was just mild steel. The billet only cost $40. But that was 13 years ago. Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted October 19, 2012 Author Share Posted October 19, 2012 Once I have the engine out I can see what I can do. Come Tuesday I can ring around Nelson for steel prices. Quote Link to comment Share on other sites More sharing options...
nick_m Posted October 20, 2012 Share Posted October 20, 2012 my old work mate made a light flywheel out of mild steel for his super stock(? - the inline 6 smash and bash ones) I queried him at the time about using mild steel. He swore by it, reckoned that mild steel was much better with the heat cycles, the higher grade steels are more prone to heat cracking. Guess those inline 6s dont really rev that high, plus yours being a road car would probably be less likely to be subjected to those heat cycles. I reckon you would be alright with mild steel or medium tensile 1040 Im pretty sure those inserts on the fidanza Aluminium flywheels are only 1040. edit: Fidanza are heat treated 1050 Quote Link to comment Share on other sites More sharing options...
