Well I don't have any experience with the disk cutter, I assume it is mounted like a circular saw in which case cutting a curve will be very difficult.
With a sawsall though, a bar or stick of wood with a pin or probably even better a small bolt through it near one end and cut 9 inches from the middle of the bolt to the end minus the distance from the end of the shoe of the sawsall to the blade then drill and saw or file enough length to get the blade of the sawsall through. Then drop the bolt on the end of the stick through a hole at the center of the circle and I think I would slip a lock nut on it to be sure that vibration or other things won't allow it to come free. Then keep the edge of the shoe of the sawsall against the end of the stick or bar and if anything just keep the saw very very gently turned toward the center of the circle just enough to keep it from tending to wander away from the end of the stick and then make your way around the circle using the rod or stick to keep you equally spaced away from the centre. If you can manage with light cotton gloves I recommend it. The blade you will be using will have very fine teeth so that isn't much trouble but it can get pretty darn hot and it is also a little difficult to keep the shoe against the end of the stick while keeping your fingers from getting pounded by the shaft and blade holder and often small shards or curls of wire cuttings. Well that is my suggestion. I haven't cut a lot of metal though and the hood won't be flat I am sure, they are usually contoured so it may be a little difficult to track perfectly. Hope this helps.
