I've read a couple of interesting threads on here about lightened flywheels recently, the 'modern' way of doing this seems more effective at reducing weight and probably stronger / less risky than drilling millions of holes like they used to back in the day.
So, where does that leave the 'Swiss cheese' type? I always had doubts about weakening the thing and I'm not sure how far you can safely go. Do we know of any cases where a drilled flywheel has failed? Is there a critical area to avoid?
I only ask because I have a drilled flywheel in one of my boxes and I'm wondering whether to hang onto it or not. Will become pertinent soon as I'm building up an engine which is currently short of a (Ruby/ Newton Bennett) flywheel and clutch assy.
Thoughts welcomed...and yes I'll put up a pic when I get a moment...
