Direct driving the shaft takes a bit of horsepower.....1/4 horse will do it, 1/3 horse is better. Mine was a 1/15~ish hp with a 4:1 belt reduction and still needed a bit of help sometimes.

No need to worry about wizardry, just use a variable speed motor (or not). I prefer 90vdc myself. A 3-phase motor and a vfd will work too. More than one person has used a fixed speed motor.....just remember you can't slow down for corners or speed up for long boring beads. DC or the vfd option allow for easy reversing. Single phase motors do not allow easy reversing.

A gear reduction is a must! Mine was 87rpm with a 4:1 belt reduction, resulting in 22~ish rpm at the dies......even with 2" dies, that is moving pretty quickly!
