Hi Mike
I went 150ml as I remember reading that 6 pumps was max before mixing. To be honest now I've done one round of this I think doing it in one shot would work OK. Maybe rig up a cordless drill on a stand with bent wire in the chuck and run this slowly between every 150ml added and then one final stir at the end.

Would be interest in the Diamant. The 1kg epoxy kit i used was about £40 plus postage, how much was your kit ?
I'm expecting to have to dial in the last bit of level so would be interested in how you got on.
