Help! Adapter seized on my Atik 383l+ (Solved)

[kbrown]

Wanted to swap the camera on my filter wheel but this time my Atik came off with the camera-to-wheel adapter stuck on it really hard. It's quite thin so it's hard to get a grip on. I've tried with a sheet of rubber around it and twisting with locking pliers to no avail. Not sure how I'm going to get it off. It's getting a bit scuffed by my attempts already. Any ideas? 

I'm kind of scared to do anything radical with the thing on the camera itself. Can I open those four bolts visible in the photo to get the black ccd chamber bit off or is that going to screw up something?

Try putting a thick rubber band around it and see if this helps. In the past I have used one of those clamps you can get to help you remove jar lids or look on ebay for a baby boa constrictor.

Pliers are not a good idea, if you distort it it will never come undone, try the sole of a trainer pressed hard down on it and twisting.

If you're not bothered about saving the fitting you could araldite a longer fitting into it.

Squeezing the ring just distorts it and makes it grip tighter, try placing the camera face down on to a hard rubber sheet, something like a car floorwell mat or similar, press the camera firmly down onto the mat while twisting anti-clockwise, hopefully that may shift it, if that doesn’t work, wrap a couple of dozen turns of sellotape around a sheet of stiff card so that the sticky side is facing out and the card is covered over a large enough area to grip the ring , put the card on the rubber mat and repeat as before, pushing the camera face down on the card while turning anti-clockwise.

Ingenious ... will have to remember that one.

Make the room uncomfortably warm when trying the other methods suggested, this will provide an additional slight advantage...and on occasion is all that's needed to free the threads.

Best of luck ?

Next time you assemble the spacers and couplers smear a little of the hard, black, boot/shoe polish over the threads before you screw them together, it helps prevent them binding....?‍?

I've been using the "boot polish" trick for the past twenty years.....it works!!!

Me too but not that long...

Rubber gloves can be helpful  I wouldn't advise taking the front of the camera off except as a last result, Undoing it will a) let in moisture and b) let in dust. Both can be dealt with but dust on the sensor, especially, can be a pain. Plus having an unprotected sensor is a risk.

That's what I've been using until now. This time it seized properly. I got it sorted thanks to the previous tips on this thread. Essentially I put the rubber glove on the floor and stood on it to prevent it from moving. Then I pressed the camera down on it with the adapter in contact with the rubber and slowly rotated the camera anti-clockwise. Eventually the adapter came off neatly.
