For those of you who use the Bushmaster/brass cauls for key bushing: One problem I've experienced with the Bushmaster tool is its willingness of the lower barrel part to unscrew from the rest of the assembly. Short of using a pipe wrench, one thing I found to work well for keeping the assy. together is to put a wrap of Teflon tape around the threads (the same as is used for compressed air fittings). Since I put the tape on, no unscrewing - been at least a dozen bushing jobs now, and it used to come apart any number of times during a single job. William R. Monroe
