Yes, just had a little look at it then there wound back, enough for it to slide back, will do it tomorrow too, I think I will do it! Still want a new frame though :') And I just took another quick loot in the shed then, I use to have to kind of tap my old wheel out like the dropouts were cramped not that way -->, but ^ that way, May just have a cheeky little file down to make it fit upto the tensioners, as the frame is pretty much on its last weeks! 
 
EDIT - was writing that while going back and froth, what dan said basically yeah ahah, cheers for all the help guys means alot!
