Help! M42 to K adapter-get it off my ZX-5n, please

[Dan Scott]

My screwmount to kmount adapter just came from B&H.

Screwed it on to the Jupiter-9, no problem. Put that on the ZX-5n, pretty iffy, can't tell if it's on all the way or not cause the focus scale isn't really lined up where it should be.

Go to take the lens off and try again, the lens comes off alright, but the adapter is fast on the ZX-5n. The tool that comes with the adpater turns it a little, but not enough.

Anyone have this happen before? Tell me you didn't have to take it to a service center to get it off, please...
