Yep, the stuff you used to put on the school books - well we did in my day! "Contact". Try one wrap and see if that takes up the gap between the collimator and the 1.25" adapter. If that doesn't work, try two wraps. I have found one wrap of a GSO collimator was sufficient. You want it nice and snug, but you don't want the contact on only one side - ie. not half a turn or 1.5 turns.
