I have a few sections from a used yagi purchase that are like this - a few
of them I managed to get apart with lots of effort using a screw driver in
an existing hole and lots of pulling ... the rest just wouldn't budge.
Heating I don't believe works - its near impossible to heat them
independently - so they expand together... I tried WD-40, and the slippery
stuff - can't remember its name but for this purpose - nothing worked. These
pieces are now in my scrap pile replaced with new material from DXE.
