Acculap is not much good for faster aspherics , as it doesn't really flow well or at least the stuff I tried didn't . If the channels aren't closing up the lap isn't flowing .
Its popular in industry for machine polishing spheres.
When you say expensive , how much per kg are you talking landed in Aus for Acculap ? .
I have a fair bit of Tivoli Coronapech german pitch ex CSIRO , I will probably never get through , I could part some but you would need to be comfortable with adjusting hardness by adding some rosin to harden . Its probably similar to a Gugolz 55 in it's current state .
