[TowerTalk] Thrust bearing Help

WD40.  You can use a propane or napp torch to heat the bearing.  The
aluminum will expand more than the steel and possible break the
corrosion/rust.

I have a Glen Martin  TB-25 Thrust Bearing 

 

I am having trouble   BACKING OUT   the set screws that lock the Mast in
place

 

This TB-25 is made of Die cast Aluminum.

I have used WD-40 and several other sprays. 

 

I just can't break loose the bolts.  I just don't want to break the bolts or
the top housing of the TB-25.

 

Any ideas on what to spray on the bolts that will help break them loose
