Still thinking about what to do with crank cleaned it up a bit and took a better pic, that nick in middle looks quite deep, also there is a lot of pitting. Rang them for prices today, health check just to say what it needs is £36, polish another £40, Regrind £185, measuring was extra and full total would be £285. If he says it does need regrind which I think he will then its a lot cheaper to get this one on ebay. Its gonna be a hassle to get to machine shop then drop crank off and get back another day to pick it up in between work so thinking should I take a gamble and get the ebay one and save money, If it does need a regrind then thats a no brainer
