Subject: RE: Loose or Sloppy Joint Ferules
OK, here's how my connections work. You guys tell me if I'm close to being right. |
My pole sections are lightly sanded so that a six-inch brass tube (.10 inch wall thickness) can be fitted very tightly over the last three inches of one of the pole tips. That leaves three inches of the brass tube female end for receiving the second pole. The wood male end of the second pole is lightly sanded and inserted into the felmale end for a snug fit. That's it: two pole sections connected by a six inch brass tube held together by friction.
The problem doesn't seem to be with the wood expanding or contracting, although I can see where that could be a problem over time. The problem seems to be that the brass connection on the female end is being expanded by normal flag waving usage over a relatively short period of time. I can't increase the diameter of the male end of the second pole to compensate unless I add something to it like a thin brass fitting, so either I get new poles or new brass tube connections and start all over again, or I try adding some type of shim. As you all have pointed out, that will probably lead to stuck connections and me inadvertantly expanding my young flagman's vocabulary.
For those of you who have been doing a signal impression for several years, what are your solutions?
