Skateboard wheels is there anything they cant move?

   I use an  old 44 gallon drum trolley with the handle cut off solid as all hell and sits the machine at a good height to work on for a midget like me.     Does anyone else have to use a step whn working on machines

Yeah Skateboard wheels are great aren't they Daniel . Maybe one day I will make something more decent for working on Pinnies but for now this will get me by as far as moving them .. and my old saw horses to sit em on if I can't be bothered putting the legs on.
