flywheel resurface Machinist question

[Tree25]

My dad is resurfacing my flywheel... he is new at the engine parts end of it but he claims is pretty simple. One question is brought up... Can the surface be too smooth? Its nice and fresh looking after he put it on the the machine to take off 5 thousanths. A co-worker sugested to put it on the lathe to have it a bit coarse for the clutch to have somthing to bite into. Otherwise I may get a lot of chatter as the disk will not grab the smooth surface as well.

The theory sound great but wanting someones .02 cents who
has expierience

What is he using to surface it? There is a typical surfacing machine for this and not done with a lathe.

Having some surface texture will seat a new disk quicker.

FYI, the step in the flywheel is critical to keep.

The perfect refinish job is done with a grinder and the surface should be nearly mirror smooth.

Video was cool, I wondered how that was done.

I have a feeling it's a good idea as well to have it balanced. Is it internal/ external balance and do I get it balanced to the rotating assy or just to zero etc.
