As discussed in this forum, flop tube weights are mostly of two varieties. The metal-to-metal or the o-ring. The metal type scores the bottom of the tanks, and the O-rings have come apart or come off inside the tank. I have developed a new weight that will not score the tank or come apart. I have one in my skybolt tank now (5 hours so far). It is approximately 3 inches long, 6 ounces, with 1/4 NPT threads in hose end. The end piece is Delrin and is free to rotate to minimize wear. It is swaged (flared) in place and cannot come off. I would appreciate any thoughts/comments from everyone.
