Trevor,
Even though I soaked the beam in kerosene overnight the bolts are still stuck fast to the spacers. <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" />
I even tried the cold chisel but all it did was put a small groove in the aluminium. <img src="http://www.catsailor.com/forums/images/graemlins/crazy.gif" alt="" /> I really didn't want to chisel too hard in case I started to elongate the beam holes.
The rear beam is still OK but I don't know for how long. Luckily the inner fasteners are cap screws located on the lower face so it's only the outer bolts I have to work on.
If I apply localized heat to the spacer maybe that would work otherwise I might have to get the hacksaw blade out and cut through the bolt at the inside. <img src="http://www.catsailor.com/forums/images/graemlins/crazy.gif" alt="" /> Maybe I should invest in a flame torch and give it to myself for fathers day <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />

Peter
