Right then guys, I've had my A5 for a good 4 years now and unfortunately several of the alan bolts that hold it together have rounded off at my last strip down, I cant get the damned things out now and I really want to get it apart to clean up, oil etc. Any tips on doing this without damaging the marker? I've thought about either cutting grooves into them with a dremel so I can get a flat screwdriver in, or possibly bash a slightly larger torq wrench into them to extract that way, but just thought I'd ask before diving straight in. Also is there anywhere that I can get hold of some new bolts? I know the A5 parts kit has a couple in (which I've used) but I dont really want to buy yet another complete kit for the sake of 2 bolts (cos I'm skint & tight )
