anyone ever use a bicycle inner tube for this? i want to try it. i also found a air filter from the yard at work and tossed it in the fire pit, 2 screens were the product. free and looks like a good fit. i have several bicycle inner tubes to use. and pvc pipe galore. i am wondering if a towerpro mg995 servo continuous rotation will do the trick to spin it, or if i should use something else.

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
