I have a Graflar lens for by Century Speed that has been mounted so tight to the lensboard that it's jamming the lens opening and shutter controls. Not only that but the local camera repair shop claims that it's also GLUED to the board. Nothing that I have tried seems to work. It's has even broken a spanner wrench. Any ideas?

I'd procure a new lensboard and then carefully destroy the old board with a cutoff tool on a dremel first then a rotary rasp when I got close to the shutter essentiallly cut the board in half or thirds and break the parts out.
