Hi James
No worry beads needed
but practice on some scrap boards would pay off big time it's easy to get the hang of this simple jig , 3 or 4 slots and you will have it down, then it's just like getting on a bike after 10 years or so, once you got it you got it..
it's all in the balance ....
You could get some longer pins (bolts ) and used them as training wheels so to speak until you get the hang of it, they do most of the work, keeping it running true and supporting the router from tiping over from one side or the other just like training wheels on a bike so to speak ...
