I have just had an idea for aligning holes in cases where access to some internal item might be required (and I wish I'd thought about it some time ago). It occurred to me that lots of simple little devices (such as laser pointers, laser measurers, laser torches, IR thermometers and the like) have a laser beam incorporated. If the item that needs the access-hole and the laser-pointer device are aligned without the casing being present, making as sure as possible that the laser-beam is aligned horizontally and vertically with the item to access, then when the casing is in place the laser-spot will mark on the casing where the hole needs to be made. This necessitates that neither the laser-pointer nor the device that needs external access are allowed to move between initial alignment and replacement of the casing, but that should not be beyond the wit of man. I may not have made myself clear and I haven't personally tried this idea out. I think it might just work. It would certainly be better than the bodges that I have done in the past. Who wants to be the guinea-pig?
