The topic of "Teflon Tape" appeared in a "thread"/thread down in "Setup and Repair" today ( "Loose Tip"). I've used Teflon Tape, (as used in the Plumbing Trade), to eliminate the "creaking" of the bow screw that occurs on almost every German bow I've owned. I wrap enough layers of Teflon Tape on the bow screw, (ONLY on the un-threaded section of the bow screw), to eliminate the "slop" in the thru-hole ( in the stick), that the screw passes thru. This slop is usually the source of that "creaking". Trial and Error is used to wrap a flat, consistent layer of just enough tape to eliminate the looseness/slop. You're Welcome. Thanks.
