Quoted from yancy:I don't see why not. I just slapped a mylar circle over that whole area. Reminds me, I want to buy a case-hardened magnet core from Pinball Life to replace the factory core, aka mushroom waiting to happen.
My sparky magnet is a mushroom now. I did not know that you could get a case-hardened magnet core or I would have added that to my last order.
Is this the magnet core? http://www.pinballlife.com/index.php?p=product&id=1837
What is a good place to source the mylar from?
