Hi Julie,
I blot sequencing gels 'cause I employ non-R/A detection. I think it is
referred to as "dry" blotting: simply wet the memb. with water, lay it on
the gel still stuck to one plate, put a sheet of 3MM or the equivalent on
top, followed by the other glass plate. It transfers in 10 min. 
Of course this is for a 0.25mm thick gel.
Doubt if that would work for anything much thicker...
Good luck,
