Adapter Ring Won't Budge... Please Help!

[PhotoGav]

The small adapter ring that goes between my CCD and the skywatcher reducer for my 80ED is stuck on the reducer... I just can't move it. I have tried the rubber glove trick, which normally works, but it is well and truly welded on this time. Please does anyone have any cunning tricks to help it move?

Thankfully it is stuck in a useful position, so I can still use everything, but it just annoys me that I can't remove it!

Thank you.

Put it close to a radiator, then use the rubber gloves, make sure its sitting in the palm of one hand while the other palm presses and twists, keep them flat don't try to unscrew  the items...

Tinker's suggestion is good. If it doesn't work I suggest that you put the reducer on a flat surface with the front element facing up and cover the front element. Squirt a little WD 40 between the stuck adapter threads and leave for 24 hours and it will come loose. Do not spray the WD 40 all over the place as it is not good for the coatings. As the rear element of the reducer is facing down, sitting on the adapter, the WD 40 will only penetrate downwards and not toward the rear element. Use rubber gloves to unscrew them. I had two ultra low profile M48 to T adapters that had got stuck due to over tightening and nothing would get them loose even a hot hair drier gun but WD 40 did the job. Keep a very thin film of WD 40 between the threads and they wont get stuck again unless over tightened . When I make parts for my model engineering projects I do make sure that Aluminium is not used for screwing parts together to avoid fusing.

Thank you folks. I will give those ideas a try straight away!

I'm embarressed to admit that I put it outside in the cold last night, thinking that would help... Doh!

Ah, the joy... It was almost worth getting them stuck just to feel the thrill of getting them apart! WD40 won the day.

Thank you so much for your help guys, here's a virtual beer on me. Happy New Year to you both!
