A friend sent me a photo some time ago. He hung the stock vertically with the head down and applied a heat lamp over a period of time. The photo actually shows a stream of oil coming from the stock head.
Or even in the oven. You wont beleive the puddle of oil that will be on the baking sheet inder it after not too long.
I first use acetone soaks. Then set aside for a few days in a window. If oil keeps coming up to the surface then it needs another soak. If after 4-6 soakings it is still coming up, i then resort to heat. That usually gets it all.
