Hello,
cheers for the tips, I think I will raid my Girlfrined bathroom cabinet for nail polish remover and carefully give that a go.
Normally I would try just popping it off carefully with a knife, but the part I glued on wong is a fairly fine ring for one of the top turret ports which sits in a hole in the cast resin turret.
I was having a ponder and I thought that as the turret is quite chunky and wont warp i might sit it in warm water and see if differential expansion might loosen it up a little bit first.
Thanks for the help
