Ehab, tried that and found it very slow going, really had to work the hot blade to make any progress. It certainly did not like anything with cf reinforcement which is often the case in areas where cut-outs are required.
Jason, found the blades blunted real quick on those razor saws, with the small hack saw blades just re grind the tip when it looses its bite and away you go.
Often wondered if there was a miniature version of those 'cutters' they use to remove plaster casts from broken limbs, might be useful in our game!
