Steve,
This mod can be done without taking the scope apart.
Roll up the flocking paper(don't remove the backing--you're not gluing it in yet) into a tube slightly smaller than the inside diameter of the primary mirror's baffle.
When you insert it in the back, it will unroll until it fits the inside of the baffle tube fairly snugly.
Make certain it is not long enough to stick out the front of the baffle tube.
Star test the scope. Eliminate the problem? (Sounds like it might be yes).
Remove the rolled-up flocking paper and be certain it is exactly the length/width to go around the inside of the baffle WITHOUT OVERLAP. Remove the backing, and roll the tube until it just barely overlaps. Insert the tube into the baffle(try very hard not to hit the sides of the baffle tube when inserting). Insert a piece of wooden or plastic doweling slightly smaller than the I.D. of the baffle tube and roll it around the perimeter of the baffle to press the flocking paper in place.
If this seems to be difficult because you doubt you can stick it in without touching the sides of the baffle, then before you pull the backing paper off the adhesive, cut it into two strips and put one strip in first, then turn the scope over and put in the other strip. Remember: NO OVERLAP. The adhesive sticks very well to metal, but not to the fuzz on the top of the flocking paper itself.
So, no dismantling necessary.
Good luck.
