Greg you could try using the swansdown mop to generat heat.
Make sure it is loaded up first on another bit of wood as this helps getting heat into the mop before you start on the peice you are working on.
May help with the oil as well to get it burnished into the wood instead of sitting on top.
Heat here is the key factor on boards etc where you dont have the assistance of the lathe and your knuckles to generate heat.
