Removing FSA chainset?

[andyoxon]

Any ideas how to remove the drive side crank/chainrings of this FSA Gossamer chainset.  NDS crank is removed but the axle (arm) doesn't knock out; so appears to be stuck.  Carry on with hard wood block and heavy hammer? What types of BB bracket is the one installed?
