    How much crown should be in the pan roller of the Alcolor dampening system?

    If your roller supplier will turn the roller to custom specs I prefer a .004 crown for a 40 inch alcolor unit running without isopropyl. On a speedster 72 or 74 I prefer a roller with NO crown

    Ok, I am doing test trials on a GTO52 for the IPA free conversion. Should I order pan roller with crown or without?

    I'm thinking that no crown should be needed on a GTO just because of its size but thats just a guess as I've never run one.
