   Hi all
   
   Just wondering what every one thought about this. I work in engineering and regularly work on lathes Nd milling machines. Could I get hold of a standard flywheel and make some groves in it etc to make it lighter? Obviously keeping it all balanced. What you think?
   
   Cheers paul

   Yes you can mate knowing your engineering is key. You need to remove material to keep it balanced is the key and making it lighter to the outside and leaving material on the inside.

   unless you know what you are doing id strongly recommend you dont do so.
   
   Even working with milling machines on a daily basis doesnt mean you will be aware of the weight you need to remove etc.

   as above if you dont do it right it could crack and explode or be unbalenced. driving around with an unbalenced wheel is bad so imagine bolting it directly to the crank.

   have a look at some videos on youtube about exploding flywheels, then ask yourself is it worth the risk Standard flywheels are cast and shouldn't be played around with if you ask me, a light skim to balance it at the most!!. If you want a light flywheel get a steel or alloy billet one.

   Im an engineer too
   I work on cnc stuff all day and could do one as you say
   
   After weighing up the pros an cons i bought one its not worth the risk and the time doing it as tbh they arent that expensive
