Looking for some advice on the best way for creating the crankshaft and camshaft holes. I have roughed most of the material away by drilling from both ends but now I'm at the step where they can be taken to size ensuring they're true and parallel to each other.
We've tried line boring on some scrap aluminium and not getting consistent results with it, personally I think the bar is too small a diameter and is flexing as it's cutting even on light cuts. My next thought is to mount it on the lathe and use a long series reamer for both holes which would give a significantly better finish then I've been getting with line boring. Can anyone can offer any advice or perhaps a different method?
