This is pretty much my first trummel build and im using a pretty heafty gear motor to turn it ..motor seems to be working fairly hard but we will see when its loaded full of dirt ..I remember my fathers big unit about a 7 foot diameter tube was really struggling when fairly full..We even twisted a drive shaft a time or three ..that little izuzu diesel was smoking pretty black ....Gravel mixed with water feeding sluice boxes ..Water probably helped keep the friction down ..wonder if turning dry gravel is a bit more difficult
this is the unit that inspired me to build it this way
