Most of my students came in with this compass. Right out of the package it is not tight and will not hold a measure. Constructions are hard enough for beginners without this hurdle, and has kept me much busier helping poor students gently draw arcs than I should be. I haven’t had time to even look at the compass to see if it could be improved. I just assumed it was a plastic piece of junk (btw, it IS). But today, one of my students said, “All you have to do is tighten the screw.” Eureka. And yes, I gave her a lollipop. Bless you Jordan.
First of all, you shouldn’t have to tighten the screw on EVERY LAST COMPASS right out of the package. Second, I know it won’t stay tight for long, if at all. Shame on you Fiskars.
But if you are stuck with this compass, at least you have a temporary fix.
