So the shadowgrah is mostly working after I read the directions carefully. There is one issue however. This is the newer style shadowgraph. The circular washer with the split at the back (I suspect this is the magnet) is loose. It shifts around as I try to adjust the shadowgraph and even drops almost out. Can I secure this with something? Perhaps a couple drops of candle or bees wax melted on top of it?

Thanks,
