how are butterflies removed on a qjet

How do I remove the butterflies on a 4bb qjet?

Best way is to grind the threads off of the exposed portion when you open them fully, then turn the screws out. If you don't, the heads typically break off, then you need to replace the shafts.

I've got the screws out before without cutting the exposed threads off, but I took my time, and am probably just tempting fate.

Why do I need to replace the shaft? I was able to remove the segments by using a vise-grip on the ends sticking out. Now I need to find the screws to fit this.. didn't see any at the hardware store. I'm I OK to still use the shaft? Is your concern that the stress I put on the shaft threads might cause the screws to become loose? What if I were to flatten out with a pin hammer where the threads come out. Might I cause damage to the shaft? Lots of questions here. Thanks for all the help dyeager535. I'm in Seattle also.

He was implying that if you break the bolts the threads are stuck in the shaft and you have to replace it because you cant clear the holes. You seem to have gotten the holes cleared so there is no need to replace the shafts.

The screws are 3-48.
