Magnifying glass

I'm stuck where the magnifying glass and the alligator clips are. I can't seem to do anything there yet it keeps telling me to go there. It's the room to the right of where the staff is
. Anyone know what I'm supposed to do?

When you have all the beads go to magnifying glass. You have to engrave the beads there.

I think I have all of the beads, but the hint keeps telling me to go there and when I try to put anything on the table it says I don't have everything I need. What else does it want?
