Eberhardt bun molder question
I picked up this sweet old Eberhardt bun molder. I've just finished putting it back together after a good clean and relube. My question involves the adjustment knob pictured.The knob spins up and down the threaded rod that is numbered 1 to 7. I can see that when set to 1 it molds in large revolutions and set to 7 in very small revolutions but I can't figure out how this applys to my doughs....I assume it has to do with different dough stiffnesses but I'm just shooting in the dark hear. I've looked for a manual but it's a pretty old model(Eberhardt BT30) and I've haven't had much luck. I'd appreciate any info anybody has on this machine.
