I don't know where you are. Here in Maine, it's cold out.
Get the whole end of the mast/base cold, then quickly heat all around only the mast with a propane torch, waving it a bit. As the mast expands it will pull away from the base. Alternate heat and cold, always heating just the mast. You are trying to keep the base cold, while heating the mast to increase it's diameter. As soon as the heat flows into the base, stop and let it cool.
Rapping around the circumference of the mast where it's bound to the base also stretches the metal, and as mentioned helps to open tiny voids for capillary attraction of the PB blaster or other penetrants, like automatic tranny fluid mixed with acetone.
