M42 k mount bower adapter Stuck

Im sure youve heard this 1000 times but ive got a serious issue here.

Ive spent over 10 hours trying to get this thing off my k20D and it will not

It can turn about 75-90 degrees but it wont get to the point where it actually releases

it also wont lock tite, no matter what lens I stick on it will still rotate freely about 75-90 degrees (estimated) so I have to kind of hold it in place

Im not sure what happened as ive used it several times with no problem and the last time it just wouldnt click into place to secure it and also wont remove.

I know all about the locking spring mounted pin and trust me ive tried everything here, depressing it DOES NOT work, and doesnt make a difference

Im at a point where Im about ready to pull out the chainsaw and getting my revenge

i use about 7 m42 lenses and 9 k mount lenses so it needs to come off.

Does anyone know if repair shops can help remove this or if i can send it back to pentax (its under warranty but this is obviously not a warranty issue)

how much do u think pro repair will cost? Im not even sure if they can remove it as I said ive tried for over ten hours. its been stuck on a week and also every time i mess with it its spitting metal shavings inside my camera. looking in the viewfinder it looks like someone dumped coffee grounds inside (terrible) alas none of it is coming up on the images so it must not be directly on the sensor. Ive tried mirror lock up and blowing to remove the flakes but they arent coming (very scary)

So you have any ideas or suggestions? im at wits end.

Ive tried multiple forums and i just get re routed to this one so hopefully u guys can come up with an answer.

it gets to the point it wants to come off but it just wont budge further and like I said the adapter freely rotates instead of locking in place. Is it turned around or something? I cant seem to get it to rotate any further incase it went past the correct release point.

im not even sure what to try or what is causing it as the releasing pin pushing, pulling, pressing, depressing, jigglign and jarring the mechanism doesnt seem to help at all. Same problem and its not getting me anywhere

Soon as this thing comes off im sending it to the company and letting them know how terrible they are (im sure they get tons of hate mail already)
as i see people all over with the same problem, unfortunately no one seems to post up the solutions, just disband the forum once they get it off and move along. The other posts ive seen on this website and others i have tried but have not received any luck from those solutions

thanks for listenikng and hopefully u have a solution that doesnt require an axe or chainsaw.. its getting close to that

Try to rotate it forward rather than back, to the next K mount slot, where you can remove it. Happened to me also, and sometimes going forward is better than backwards. With the lens in may help

ive tried rotating it in both directions and it seems that one side is looser when its turned clockwise opposed to coutner clockwise however either way it still gets to a point where it wont turn any further

It came with a key to help it go - use tiny pliers or long fingernail, and probe for the spring loaded locking bit in one of the slots. Try moving that while at the resistance point.

And, if you're gentle but insistent, you can overcome the resistance. Don't go brute force, just insistent.

Check here:

It is possible that the clip and/or the screw is off and somewhere in the bajonet. You have to try to locate it and remove it, perhaps with a forceps. Turn and shake in all possible positions, up side down.

thanks but ive been to every m42 adapter site known to man and like i said these solutions arent working for me.. that site doesnt even offer any solutions, its someone explaining that they can be altered to prevent this (which doesnt help when its stuck ont he k mount)

I am well versed in how this adapter works, as ive been using it a while ... this isnt a matter of ignorance there is something preventing it from removing.

Ive tried all these things and u are only reitterating what ive tried from my message.

So, is the clip still fixed and present? Can you see it?
I am wondering what you mean by "75-90 degrees". Normally it is only needed to rotate it by about 45 degrees to get it off.

Can you please take a photo of it, with the two extreme positions you can turn it?

yeah the clip is still present and still moves, but seems to no longer affect anything.

regardless of the position of the clip, the adapter moves and yes i agree it is moving more than it should. I will post some pics tonight of what im talking about. i appreciate u attempting to assist

I hope when i get pics uploaded (wont be until tonight) you will have a better understanding of my situation
