I wouldn't personally run without it. But I have lots of stones. I have seen some old 1480s without a stone trap at all. There should be 2 pins that attach the feeder house to the stone trap and 2 pins that attach the stone trap to the machine. I believe you can just pull the stone trap out completely.
Hopefully someone else can confirm my idea before you go ahead and do it.
I had it off, and almost did that but was worried I would have to replace the belt running it with a smaller one since it would be now 6 inches or more shorter with the trap off. But if you could, I probably would for now until I could get the razor on. Not against the rock trap, but if it allows me to cut again, I would take it off in a minute.
