Help!!

[eyepod]

Hi all, i have set aside today to flock my 200p flex tube dob have done the front end and looks great BUT moving to the scary end i cannot remove the primary... have tried tugging twisting even making a handle screwed to the m3 threads that arn't used on the back of the cell assembly but it still won't budge am now thinking of using a hot water bottle to apply gentle heat to the tube hoping it might expand and release.........any idea's most welcome

thanks

Jason
